U.S. Department of Energy (DOE) Secretary Steven Chu contributed a statement to an announced breakthrough in research into tapping the vast fuel resource of methane hydrates that could eventually bolster already massive U.S. natural gas reserves.

As Al Fin pointed out yesterday natural gas is priced to a barrel of oil equivalent at about $10-$11 per the estimable Geoffrey Styles view, something less than 10% of the cost of oil.  For North Americans adding a viable and hopefully low cost means to make use of gas hydrates could be giant boost to low cost fuel sources and a massive kick to the economy.

For experts the methane hydrates resource is the largest reserve of hydrocarbons in the planetary crust. So far humanity has not devised a process to economically harvest this immense energy wealth. Today’s DOE announcement may point the way to a new era in abundant energy to build out a bigger and better world economy.

By injecting a mixture of carbon dioxide and nitrogen into a methane hydrate formation (pdf link) on Alaska’s North Slope, the DOE partnering with ConocoPhillips and Japan Oil, Gas and Metals National Corp was able to produce a steady flow of natural gas in the first field test of the new method. The test was done from mid-February to about mid-April this year.

The department said it would likely be years before production of methane hydrates becomes economically viable. Secretary Chu said in his statement, “While this is just the beginning, this research could potentially yield significant new supplies of natural gas.”

Methane hydrates are cold ice crystal-like structures that contain methane the chemical of natural gas. The hydrates are located under the Arctic permafrost and in ocean sediments along the continental shelf and widely spread worldwide.

Gerald Holder, dean of the engineering program at University of Pittsburgh, who has worked with the DOE’s National Energy Technology Laboratory on the hydrate issue, said before the announcement he had been sceptical about what researchers would be able to accomplish.

He said the main problem until now was finding a way to extract natural gas from solid hydrates without adding a whole lot of steps that made the process too expensive, which makes the success of this new test significant.

“It makes the possibility of recovering methane from hydrates much more likely. It’s a long way off, but this could have huge impact on availability of natural gas,” said Holder.

While everyone is suggesting that methane hydrate production is some time in the future, we might note that a partner is from Japan, a country that has been buying via imports virtually all its energy and fuel inputs.  A glance at the map of potential reserves shows that Japan may well pour on the intellectual and financial power to get results much quicker than many expect.

On the other hand, for North Americans natural gas is ratcheting down to dirt cheap, with more resources with the new horizontal drilling and reserve fracturing available on land and significant amounts of natural gas at sea in already developed areas.

For everyone the matter of coming up with the CO2 for the injection is going to be a significant issue.  First just gathering it remains a significant problem.  Making it from – natural gas – is the preferred method today.  That raises the question if the CO2 injected is lost to sequestration or is it recycled for reuse, or what proportion is being lost or recycled?  CO2 is very useful and it may become a valuable resource in its own right very soon.

Abundance makes a lot of things that weren’t viable at a price possible at lower costs.  Abundant fission or cold fusion could make electrolysis viable freeing hydrogen for adding to coal for both liquid fuels and CO2 sources.  Scaling could make such concepts usual and common thinking very quickly.

For now though the DOE and partner’s news is very gratifying.  It must be giving the futurists at OPEC an OMG moment, again.  Things are going to be changing.

Let’s hope the DOE and the partners spill some more info soon so we can have a better look.

Source: Huge Natural Gas From Methane Hydrates Process Developed

Since the end of the last ice age 21,000 years ago, our planet has seen ocean levels rise by 120 meters to reach their current levels. This increase has not been constant, rather punctuated by rapid accelerations, linked to massive outburst floods from the ice caps. The largest increase, known by paleoclimatologists as ‘Melt-Water Pulse 1A’, proved to be enigmatic in many respects. A study recently revealed the mysteries of this event, without doubt one of the most important in the last deglaciation.

A recent study demonstrates the link between observed fluctuations of atmospheric jet streams and the theoretical concepts that describe why jet streams exist. Atmospheric jet streams are fast-flowing currents of air found approximately 10 km above sea level in the extratropical regions of both hemispheres. Because these jets influence regional weather patterns, there is great interest in understanding the factors that control their path, their strength and variations in both.
