The Engineer-Poet recently had a post on The Cogeneration Stopgap at the Oil Drum, which looked at how the combination of cogeneration (generating combined heat and power - CHP - using natural gas) and heat pumps could be used to heat North American homes much more efficiently and extend the life of North America's dwindling natural gas reserves for a period of time while houses are retrofitted to make them more energy efficient and natural gas use is replaced with electricity. The only example of cogeneration technology touched on in the article was from Climate Energy, whose CHP unit is made by Honda.

An Australian company working in this area called Ceramic Fuel Cells was in the news recently after landing a $240 million deal with Dutch energy company Nuon to supply 50,000 CHP units by 2014. The company still needs to meet a number of commercial requirements set by Nuon - in particular improving the durability of the cells from two years to four.

The company is hoping that production will begin by June 2009 in a new €12.4 million factory in Heinsberg, Germany, which aims to produce 10,000 2 kW units per year. The cells are expected to emit 60% less carbon dioxide than traditional combustion generators. The company is also partnering with Britain's Powergen, Germany's EWE and Gaz de France.
