Post-combustion CO2 capture: This has the added bonus of taking
off the CO2 in a pure stream for long-term sequestration. “Solar
thermal can also provide a valuable source of low-grade heat to drive
the post-combustion capture of CO2 from existing power stations – which
is an additional opportunity for the technology,” Dr Wibberley adds.
Parabolic troughs most promising: Of the various CST
technologies, parabolic troughs are under the most active development
worldwide and appear to offer the best economics which a carbon price
would make more favourable still.
Intelligent combination of technologies needed: Van Schagen
says: “In the polarized public debate, AustraliaÃ¢â‚¬â„¢s energy challenge is
often depicted as fossil-versus-renewables. In reality, the answer lies
in an intelligent combination of the best technologies and resources to
produce cost-effective energy with next to zero greenhouse and
Aust is uniquely placed: He argues that Australia has sunlight,
coal and gas in vast amounts. “We can combine them to create ideal
energy solutions in ways simply unavailable to most other countries on
