Deputy Editor Tim Probert reports from the University of Leeds, which in conjunction with the Chinese Academy of Sciences, is developing an integrated system for thermal power generation, electrical energy storage and carbon capture. The new system combines an open nitrogen cycle with a closed, gas fired Brayton cycle, with carbon dioxide captured in the form of dry ice. Unsurprisingly, the project has attracted interest from utilities and manufacturers from around the world.
Sales of micro-CHP devices fell to 20,930 units in 2009, but in terms of power generation capacity the market size actually grew to 37.8 MWe of capacity. The 2009 market was worth some €269 million (US$346 million) – according to the annual review of the micro-CHP market published by Delta Energy & Environment.
