    China’s demand for coal is likely to peak by 2020, according to new analysis from ratings agency Standard & Poor’s.

    It bases the conclusions on the country’s GDP increasing by 7.4% and 7.2% in 2014 and 2015, with coal demand falling to single figures later this decade.

    “This is due to the slow shift of the economy toward consumption from capital investments; lower GDP growth; and the Chinese government’s increasing focus on tightening emission standards and moving to more renewable energy sources,” it says.

    “Other tangible factors include the low level of fresh water and lack of long-term quality coal resources.”

    Shale gas could be a “game changer” says the agency, but significant pipeline infrastructure needs to be installed before the country’s reserves can be fully exploited.

    China is the world’s largest coal consumer and biggest source of greenhouse gas emissions.

    In a report published on Tuesday with the London-based Carbon Tracker NGO, Standard & Poor also warns coal producers that new green policies aimed at addressing climate change will hit growth.

    “As governments globally seek to reduce their CO2 emissions, it looks increasingly likely that ‘King Coal’ will lose its crown,” says the report.

    “A significant decline in coal production and consumption globally is becoming a much more realistic concept.”

    Coal companies in Europe are likely to be hit hardest, with the report dismissing any short term impacts on coal mining in Indonesia, Vietnam, and Australia.

    It says the future of US coal will likely hinge on domestic natural gas prices, boosted by President Obama’s recent move to cap emissions from carbon polluting power stations 30% by 2030 on 2005 levels.

    And the agency suggests some coal producers may suffer from the “carbon bubble”, where shifts in international climate laws make their reserves unburnable.

    It adds: “The global coal market is in the doldrums, owing to excess supply and fundamental shifts in the US energy mix toward gas and new coal mining projects.

    “Over the long term, coal miners may experience stranded assets as a result of carbon constraints.”

    In a statement Standard & Poor’s credit analyst Michael Wilkins says “numerous factors and their timing” are likely to affect the future of coal as a major energy source.

    “Carbon pricing through either taxation or cap and trade emission reduction schemes is among them,” he says.

    “We believe new initiatives, such as those made recently by the US and China may flatten the growth in coal demand over the coming years.”

    Adeline Diab, head of responsible investments at Aviva Investors, says the report should alert potential fund managers over the long term risks linked to coal.

    “The dynamics and change of the coal market is accelerating. However, markets are currently not pricing these risks even though they are material to long-term capex plans and current market values.”

  • Measuring sea level rise Influences on sea levels

    Measuring sea level rise

    Influences on sea levels

    Many meteorological and oceanographic processes, with different time and spatial scales, affect sea levels around Australia. Influences on sea levels can be dynamic and vary from place to place. Many of these processes are considered cyclical – they oscillate back and forth. Although these processes do not have a permanent imprint on the long-term mean (or average) sea level, they can make it difficult to determine underlying trends in sea level.

    The timeframes for major influences on sea levels are summarised in the table below (adapted from New Zealand National Institute of Water and Atmospheric Research, Goring & Bell 2001external link).

    Driver Sea-level response Indicative timescales
    Gravitational attraction of astronomical bodies Tides Hours, with some influences extending over multiple years
    Wind Set-up Days
    Changing atmospheric pressure Inverted barometer Days
    Ocean currents Variations Weeks to months
    Annual temperature cycle Annual cycle One year
    El Niño/Southern Oscillation Interannnual oscillations Years
    Interdecadal Pacific Oscillation Interdecadal oscillations Decades
    Long-term global temperature changes Long-term sea-level change Multiple decades to centuries

    Some influences affect sea levels on short timescales (less than one year) including seasonal factors, weather systems and variability of ocean water properties such as temperature and salinity. The physical properties of the ocean water mass change with mixing and ocean currents, and can cause significant variations in sea level lasting from weeks to months.

    Larger scale phenomena, like the El Niño Southern Oscillation (ENSO), the nodal tide and the Interdecadal Pacific Oscillation (IPO), can cause fluctuations in sea level spanning years to decades and are more difficult to isolate from sea level trends.

    There is a distinct seasonal signature in most sea level records. For example, the Fort Denison (Sydney) record (which has been collected from 1886 until present) has a strong positive (high) bias in autumn and a negative (low) bias in spring, compared with long-term averages.

    Longer term, larger scale meteorological influences such as ENSO can influence sea levels on cycles from three to eight years (National Tidal Centre 2010external link). The inter-annual variability in sea level around Australia correlates with ENSO (Amin 1993external linkFeng, Li & Meyers 2004external linkChurch, White et al 2004external linkChurch, Hunter et al 2006external linkHaigh, Eliot et al 2011external link).

    The range of lunar influences on tides occurs over a cycle of about 18.6 years. Throughout this cycle, the moon induces a small amplitude harmonic influence on the position of mean sea level at a fixed location. The influence is at a maximum at the poles with no influence on the equilibrium nodal tide at latitudes of around 35°N and 35°S (Pugh 1987external link). The tide gauges in NSW are situated between 28°S and 38°S so the amplitude of the nodal tide for the NSW tidal records is therefore considered negligible (less than 4-5mm). Larger values than the theoretical maximum amplitude of the nodal tide have been measured in tide gauge records (Houston & Dean 2011external link).

    At multidecadal time scales sea level also varies with the IPO, which operates over time frames of 20 to 30 years (National Tidal Centre 2010external link; Holbrook, Goodwin et al 2010external link). This long period oscillation is a lengthy interdecadal fluctuation in atmospheric pressure and sea surface temperatureexternal link. When the IPO is low, cooler than average sea surface temperatures occur over the central North Pacific, and vice versa. During the 20th century the IPO exhibited three major phases: it was positive (southeastern tropical Pacific warm) from 1922 to 1946 and 1978 to 1998, and negative between 1947 and 1976. During positive phases of IPO more El Niño like conditions prevail and sea levels in Eastern Australia are lower than average. During negative phases more La Nina like conditions prevail and sea levels are higher than average.

    Tide gauge data provides a measure of the water level “relative” to a fixed, land-based reference mark. However, the land upon which the tide gauge is positioned may be moving. Many processes can contribute to the land moving including:

    • solid earth tides (relatively small movements of the Earth’s surface caused by the gravity of the moon and sun)
    • plate tectonics (movements of the Earth’s crust)
    • glacial isostatic adjustment (the rise of ground levels previously depressed by the weight of ice sheets during the last glacial period, also known as post-glacial rebound)
    • localised factors including aquifer extraction, reclamation and development loadings.

    To accurately estimate sea level change, these processes need to be taken into account. The land itself at a tide gauge might be moving up or down at long term rates comparable with the actual rate of sea level rise. This needs to be considered in isolating the real component attributable to sea level rise.

    Sea level rise along the NSW coast can be more accurately determined since the installation in mid-2012 of Continuously Operating Reference Stations at Newcastle and at Fort Denison in Sydney Harbour. These reference stations were funded by OEH to measure any ground movement which could affect the sea level recordings. This will complement the similar sea level monitoring station at Port Kembla operated by the Bureau of Meteorology. These three stations will provide useful data on sea level trends in the medium-long term.

    Challenges of isolating long term trends from sea level records

    It is difficult to isolate the smaller signal of long-term changes in sea levels from these larger dynamic influences which operate over different time and spatial scales (Zhang & Church 2012external link). Sea level records which are sufficiently long need to be used so that the more dynamic and cyclical influences do not obscure the long term trend.

    Large inter-annual and inter-decadal sea level fluctuations associated with climate variability (such as ENSO and IPO) are difficult to distinguish from underlying long-term trends of sea level rise in shorter data sets. Long record lengths spanning ENSO and IPO cycles are recommended to help distinguish between trends and long-period relative sea level fluctuations in individual recordsexternal link (Douglas, Kearney & Leatherman 2001external link; You, Lord & Watson 2009external link) and even then great care needs to taken in the interpretation of measured trends.

    Analysis (such as filtering and averaging) can be applied to tidal records of sufficient length to smooth dynamic sea level influences and reveal low amplitude sea level rise.

    Measuring sea level in NSW

    OEH supports a system of tide gauges which measures ocean water levels continuously at recording sites along the NSW coast, and on Lord Howe and Norfolk Islands. This tide gauge systemexternal link is managed and maintained by Manly Hydraulics Laboratory. Data from these sites have been presented in a range of reportsexternal link, including the NSW Ocean and River Entrance Tidal Levels Annual Summary 2011-2012 report.

    Analysing historic sea level data

    OEH is working with collaborators from CSIRO, University of Tasmania, University of Western Australia, Australian National University and Southampton University (UK) to analyse Australian recorded historical sea levels and determine trends, regional variability and influencing factors.

    The team are using publicly available tide-gauge records and satellite-altimeter data around Australia. They will also assess the quality of long term Australian sea level data, review relevant Australian sea level research, investigate spatial and temporal variability of sea level data, and analyse long-term sea level trends around Australia. The results will be interpreted in the context of global sea-level change and will be published in a refereed scientific journal.

    Past trends provide valuable evidence in preparing for future environmental change but, by themselves, are insufficient for assessing the risks associated with an uncertain future (Parris, Bromirski et al 2012external link).

    Look what’s happening to Australia’s population
    Share

    According to the ABS, Australia’s population grew by 1.73% in the year to December 2013.

    While this doesn’t sound like much in percentage terms, it is a population increase of 396,200 in the last year. Our current population increase is the equivalent of one new Coffs Harbour every eight weeks, or one new Gold Coast every 19 months!

    So let’s look into this in a little more detail…

    How big is our population?

    You can check how many of us there are using the ABS population clock which assumes growth of:

    • one birth every 1 minute and 42 seconds,
    • one death every 3 minutes and 34 seconds ,
    • a net gain of one international migration every 2 minutes and 14 seconds, leading to
    • an overall total population increase of one person every 1 minute and 20 seconds .

    Apparently there’s around 23,550,000 people in Australia at present.

    In 1966 Australia’s population was 11.5 million, so it has taken less than 50 years to double in size. While we’re growing faster than all other developed countries, not surprisingly many third world countries are growing faster than us.

    We’re having a baby boom

    Currently Australia’s births are exceeding 300,000 a year. Just to put things into perspective the original Baby Boom in the early 1960s peaked at 260,000 births yet created Australia’s largest generation – the Baby Boomers.

    We’re living longer

    And while the birth rate has been growing, the death rate has been declining, a factor of increasing longevity and an ageing population.

    Population growth from migration still a big factor

    While population growth due to net overseas migration slowed a little to 235,797 in 2013, this still eclipsed the natural increase in population (births minus deaths) of 160,357.

    Our population will grow by 10% in the next five years

    It is likely Australia’s population will increase by 10% over the next five years if we compound the current rate of growth.

    With most of this growth happening in our major capital cities this will clearly cause some interesting planning and social challenges, but it will also create some great opportunities for our real estate markets and for property investors.

    The Wheels of Justice

    James Hansen

    2 July 2014

    The wheels of justice turn slowly, perhaps more so on the most important matters.  Yet the courts, with their ability to take a long view and minimize politics, are crucial in the fight to stabilize climate and preserve our planet for young people and future generations.

    Here I comment on the status of “atmospheric trust” cases and note the appeal of an “equal rights” case. I also argue that the legal approach is an essential component in a coordinated multi-front approach that is required for success in what will be a long battle for justice.

    Atmospheric Trust.  I wrote recently[1] about Alec L. v. McCarthy, a suit filed by young people against the (U.S.) federal government.  Their case is based on the trust concept, that we have an obligation to future generations, a concept well appreciated by the founders of our nation[2], specifically the atmospheric trust concept[3] developed especially by legal scholar Mary Wood.

    On the face of it, the 5 June ruling by the U.S. Court of Appeals for the District of Columbia Circuit, affirming the earlier dismissal of the youths’ case, is a setback.  However, the Court’s ruling positions the case to proceed to the Supreme Court on the question of whether the federal government has a public trust obligation to its citizens. The Court of Appeals focused on a recent U.S. Supreme Court case, PPL Montana v. Montana, which the D.C. Circuit found to exclude any federal public trust obligation, leaving all public trust obligations to the states.  However, that interpretation leads to the implausible requirement for states to take actions to stabilize climate and negotiate international agreements for that purpose.  Thus one route to the Supreme Court will entail challenging the concept that the federal government has no trust obligations, with the climate case itself providing clear evidence to the contrary.

    Progress was achieved in a state “atmospheric trust” case on 11 June when the Oregon Court of Appeals ruled that the courts, not the legislative or executive branches, must determine whether citizens are entitled to governmental protection of the atmosphere as a trust resource.  The ruling clarified that the judiciary should decide what atmospheric protection is required by law, which the other branches of government must then implement.

    These cases, and additional ones in other states, were filed by Our Children’s Trust on behalf of young people, with “Assessing Dangerous Climate Change”[4] providing the principal scientific basis, including specification of emission reductions required to stabilize climate this century.

    Progress may seem slow, but I argue below that the legal approach is an important component of a multi-front approach that must be taken to achieve rapid phasedown of fossil fuel emissions.

    Equal Rights.  Young people’s expectation of a healthy planet derives from fundamental rights.  Our nation was founded on the “self-evident” concept that all people have equal rights.  The U.S. Constitution’s purpose to “provide the blessings of liberty to ourselves and our posterity…” implies obligations to the young and unborn.  The Constitution assures that all people will receive “equal protection of the laws” and cannot be deprived of property without “due process” of law.  These fundamental rights have global relevance because of substantial commonality of our Constitution with the Universal Declaration of Human Rights adopted by the UN in 1948.

    The legal concept that young people have equal rights may provide a relatively fast track toward judicial pressure on governments to slow emissions consistent with climate stabilization.  Therefore I am glad that Our Children’s Trust is considering, in addition to pursuing the issue of “atmospheric trust” to the Supreme Court, a new constitutional case on behalf of a new group of youth plaintiffs on the basis of these most fundamental rights protected by our Constitution.

    Success of the legal approach, via either atmospheric trust or equal rights, requires skilled, dedicated legal experts.  They are competing against the best lawyers that the government can muster and the best lawyers that the government’s “friends in court” can buy.  In the federal case their friend in court is the National Association of Manufacturers.

    The activities and legal support for cases brought by Our Children’s Trust to a large extent are obtained pro bono or at very low cost, but there are still substantial expenses associated with the legal cases.  I recommend, to those persons who can afford it, donating to Our Children’s Trust.  However, in any case, please go to www.OurChildrensTrust.org to see their story.

    Multi-Front Strategy.  Given (1) the slow turning of judicial wheels of justice, (2) the ongoing effort by the Obama Administration to reduce U.S. carbon emissions, and (3) the likelihood that international agreements, even if limited, will be reached at UN talks in 2015, is it necessary to pursue the legal approach?  Yes.  I will explain that answer further in a moment, but first let me make a general statement and note why a multi-front strategy is necessary.

    We are in a long battle against forces favoring the status quo, forces with the resources to heavily lobby and influence our governments.  As in the long battle for civil rights, the courts have the potential to help move change, because they are less subject to financial influence of lobbyists.

    The courts cannot design a plan to stabilize climate.  However, in the case of civil rights courts required the executive branch to present their plans for guaranteeing civil rights, and they could review whether proposed remedies were real and satisfactory.  Similarly, the courts can require plans for reducing emissions consistent with what science indicates is needed.

    Yet courts seldom get far ahead of the public.  Civil rights advances, such as fair voting rights and school desegregation, were ordered by the courts only after widespread public support became obvious and large-scale demonstrations occurred.

    Thus public involvement is a second essential front in this battle.  That front is led by 350.org.   The number of people is growing rapidly, but it must rise to even higher levels.  The next big jump should be The People’s Climate March on 21 September in New York City, when world leaders will be meeting for a UN summit on the climate crisis.  Let’s help make this the largest climate march in history.  You can sign up for The People’s Climate March at www.350.org.

    However, no matter how many people participate, if young people do not demand a policy that will actually work, the effort may be largely wasted.  As long as fossil fuels are allowed to be the cheapest energy, they will continue to be used.  They are cheapest because they are subsidized and do not pay their costs to society caused by human health impacts and climate disruption.

    The workable solution is to collect a gradually rising carbon fee from fossil fuel companies and distribute 100% of the funds in equal payments to all legal residents.  Thus people doing better than average in limiting their fossil fuel use will come out ahead.  This approach is necessary not only to gain public approval of a rising fee, but because it will spur innovations and economic development, leading to the most rapid possible phase out of fossil fuel emissions.

    This third front is led by Citizens Climate Lobby.  They have been growing rapidly, including chapters in several countries.  If this growth continues, especially if the transparent fee-and-dividend is demonstrated somewhere, it may be possible to overcome the ingrained tendency of politicians to grab funds to make the government bigger.  It costs nothing to join CCL.  You can participate in a local chapter or start a local chapter.  The aim is to educate both the public, e.g., via op-eds and letters-to-the-editor, and politicians via discussions with them on local, state, and national levels.  Go to the CCL website at www.citizensclimatelobby.org to learn more.

    CCL commissioned a study by non-partisan REMI (Regional Economic Models, Inc.), available as a 3-page summary or full report.  A fee of $10/ton of CO2, increasing $10/ton/year, with 100% of the revenue returned to households, would spur the economy, increasing jobs and GDP, while reducing emissions 33% in 10 years and 52% in 20 years.

    Fee-and-Dividend, or Fee-and-Clean-Energy-Rebate, makes energy costs honest.  The economy is spurred and efficient; energy infrastructure is modernized; energy efficiency is rewarded. There are great benefits for energy security, national security, economic growth and job creation.

    Fee-and-dividend contrasts sharply with the “fight subsidy with subsidy” approach, most notably “renewable portfolio standards” for electricity.  The latter subsidy increases electricity costs for consumers, but the greatest cost is hidden, borne by all tax payers.  Such forced growth of non-hydro renewable energies can be maintained only while the annual-mean contribution of these energies is a small fraction of total energy use.  Yet the forced fast growth (in percent) of renewables feeds the misconception that the sun and wind will soon supply all of our energy.

    Observing this, the fossil fuel industry gratefully festoons its web sites with solar panels and windmills, meanwhile investing hundreds of billions of dollars in technologies to extract more fossil fuels, realizing that fossil fuels are not actually being threatened by government policies.  Reality then forces politicians, even liberal ones, to approve expansion of fossil fuels, including fracking for gas and oil, off-shore drilling, Arctic drilling, and continuation of coal mining.

    Our captains of industry are ready and willing to be part of the energy and climate solution.  However, they will not be so until government policies provide appropriate incentives.

    Managing the End-Game.  Leaders of the United States and other major nations are not crooks.  However, the deception they practice, probably unwittingly in some cases, is so consequential that they may as well be.

    The deception is their presumption that they can solve the problem via “caps” on emissions.  They avoid exposing the impossibility that this approach will work by diverting attention to discussion to a barely relevant “goal” for a limit on global temperature rise.

    Young people, please listen and think about this matter.  It is not rocket science.  If you do not understand what is needed, and demand it, the planet and you are in deep trouble.

    As climate change becomes obvious, it is crucial that actions to address it not be left to politics-as-usual controlled by vested interests.  You must influence the course of events.  Otherwise, there is a real danger that history will repeat itself.  I refer, for example, to the ineffectual efforts at Kyoto in 1997 and the United States in 2008.

    Consider 2008.  Obama had a huge debt to young people, who had turned the tide for him in the primaries and worked tirelessly to get out the vote in the election.  Then they trusted their elders to do what was needed for their future.  A farcical 3000 page cap-and-trade-with-offsets bill was produced.  It looked like it had been written by Goldman Sachs and JP Morgan Chase.  Perhaps it was, given the revolving door for economists between Washington and Wall Street.  Cap-and-trade allows banks, with skilled trading units, the opportunity to make billions as carbon prices fluctuate, every dime coming out of the public’s pockets.  Fluctuating prices have negative value, compared to a steadily growing carbon fee; the latter is what entrepreneurs, business people, and the public need to guide economic decisions and consumer choices.

    There is no practical way to a global cap on emissions.  And as long as fossil fuels are allowed to be cheap, they will be burned.  What is required is a flat across-the-board rising fee on carbon, collected at domestic mines and ports-of-entry.  Border duties would be collected on products from countries that do not have an equivalent carbon fee, providing a strong incentive for other countries to have a carbon fee, so they can collect the money themselves.

    Governments in different countries would be free to use collected revenues as they choose (but not to defeat the fee’s purpose by subsidizing fossil-fuel-burning industries).  However, in most cases it makes sense to distribute the funds to all citizens, thus mitigating effects of rising fossil fuel prices and obtaining citizen buy-in for clean energy transformation.  Yes, fee-and-dividend involves some “income redistribution” as it tends to be progressive; people with large houses, multiple houses, or who travel a lot, will pay more than they receive in dividend.  However, the effect is innocuous to a wealthy person, a negligible effect compared with a change of tax rates.

    Young people, please beware of smarter-than-thou economists and politicians.  Economics is important, but the issues here are readily understandable to all.  The fundamental reason that the collected fee must be distributed to the public is that only in that case will the public allow the fee to continually rise until, over a period of decades, fossil fuels are replaced by clean energy.  So beware the economist who says “I have a smarter way to use the money; let’s use it to reduce some existing taxes rather than distribute it to the public.”  And beware the politician who uses the phrase “price on carbon” instead of carbon fee; he lacks the courage to tell the whole truth.

    Similarly, beware the liberals who will say “I have a better use for the money.  Let’s use it to reduce the national debt.”  That’s code language for “let’s throw the money in the government pot, so the government can be bigger.”  Yes, the government has budget problems, but these need to be balanced on their own.  If social security costs exceed expected revenues, e.g., the budget should be balanced internally by adjusting benefits such as retirement age, not by leaving a growing debt for young people or stealing their carbon fee revenue.

    In United Nations discussions you must avoid the temptation to mix carbon fee-and-dividend, which is handled within each nation’s borders, with climate reparations.  Almost everyone agrees that developed countries responsible for the excess greenhouse gases in the air today owe reparations to developing countries, who are suffering as a consequence while doing nothing to cause the climate problem.  Secretary of State Clinton, at a UN meeting a few years ago, suggested a specific level of commitment, as a starting point for discussions.

    Fortunately, developed countries require the cooperation of undeveloped countries to achieve climate stabilization.  It will be impossible to restore the planet’s energy balance without both rapid reduction of fossil fuel emissions and a large effort to restore carbon to the biosphere and soil, as discussed in our PLOS ONE paper.  Further, improvements required in agricultural and forestry practices are beneficial locally, as well as globally.  For physical and practical reasons, the greatest potential for biospheric carbon restoration and storage exists in developing countries.  In order to assure that the practices are carried out, the formula worked out for reparations should include a factor based on the success of a nation in achieving carbon storage, as judged by regular assessments.

    It is important that these conditions be clearly specified and rigorously upheld.  By this I mean: (1) the carbon fee must be revenue neutral, which in practice requires 100% distribution to the public, (2) international reparations must be a separate matter, for which there is a clear incentive, as discussed above.  Without firm agreement on these principles, there is no chance that conservatives will cooperate.

    The time of fossil fuel end-game is approaching, hastened by growing climate impacts.  However, it is crucial that the end-game be handled expeditiously.  It is possible that little will be accomplished in the 2014-15 UN meetings; so far they are still playing games with “caps” and “goals”.  On the other hand, it is conceivable that, say, China recognizes the merits that a carbon fee would have for them (an effective way to reduce local pollution) as well as the long-term threat that climate change poses to them.  They may well entertain a mutual across-the-board carbon fee.  Even a modest fee would be a huge step toward solution of the climate crisis.

    However, if there continues to be no effective leadership, that is no reason at all to give up.  Indeed, it is perhaps more likely that effective action will be achieved by separate negotiations among a few of the major powers.  Regardless of where the end-game is played out, pressure from the public, especially from young people, can be the deciding factor in determining whether the actions occur in time to avoid large-scale irreversible consequences.

    Yes, young people, I understand that managing the end-game is a tall order, but, whether fair or not, it’s the task you have at hand.  Do not assume that old geezers are taking care of it for you.

    Finally, I promised to come back to the matter of why the legal approach is a required part of the climate solution.  The reason is the deception and self-deception that leaders sometimes practice.  Courts can be effective in making clear that “caps” and “goals” are inadequate, thus refusing to let governments stall with those deceptions.

    Taking The Ion Out Of Lithium-ion To Increase Power Storage

    Lithium-ion batteries are everywhere because today’s technology allows them to hold the most electricity of any other portable power source. But they could hold more if they ditched the ion in the battery’s anode and used only lithium.

    But lithium alone makes for an unstable battery – until today. Stanford University researchers say they’ve taken a major step toward developing a lithium-only device that could hold up to four times the power of comparably sized lithium-ion batteries. Their research was published July 27 in the journal Nature Nanotechnology.

    “You might be able to have cell phone with double or triple the battery life or an electric car with a range of 300 miles that cost only $25,000 – competitive with an internal combustion engine getting 40 mpg,” said team member Steven Chu, the Nobel laureate and former U.S. energy secretary who recently returned to Stanford.

    Under today’s technology, a battery’s key components include the anode, a negative pole from which electrons flow to a device such as car or a smart phone, and the cathode, where the electrons return to the battery, completing the electrical circuit. Between them is a solid or liquid electrolyte containing positively charged lithium ions that shuttle between the anode and the cathode.

    Today’s anodes are made of graphite or silicon, but they don’t hold as much of a charge as pure lithium. But during use, the material in an anode tends to expand during charging. Silicon and graphite don’t expand very much, but the Stanford team says the growth of lithium in an anode is “virtually infinite” and uneven, causing bulges and eventually cracks on the battery’s exterior.

    That allows lithium ions to escape, forming microscopic branchlike growths called dendrites, which short circuit the battery and limit its longevity.

    Further, pure lithium reacts negatively with the electrolyte, depleting it and further shortening the battery’s life. Finally, contact between an anode and an electrolyte generates heat, and sometimes even fire or an explosion, and therefore are unsafe, as demonstrated by recent battery fires in batteries in Boeing Dreamliners and Tesla electric cars.

    So the Stanford team built a layer of interconnected carbon domes – “nanospheres” resembling a honeycomb – to cover anodes made of pure lithium. This layer is only 20 nanometers, or billionths of a meter, thick, yet it keeps the lithium from reacting with the electrolyte. And it’s flexible, so it can keep insulating the lithium as it expands and contracts during charge and discharge.

    If the Stanford research pans out, it would achieve the “Holy Grail” of batteries, according to Yi Cui, a professor of material science and engineering and the team leader. “[Pure lithium] is very lightweight and it has the highest energy density,” he said. “You get more power per volume and weight, leading to lighter, smaller batteries with more power.”
