The Stirling Biomass Gassification Engine in Action (Video)
This is an entry in my series on Denmark's myriad efforts in the climate and clean energy arena, and why they seem to work. I'm trying to find out if Denmark-ifying societies around the world might stop climate change ...Image courtesy of Stirling.DK
The Stirling Engine is a small-scale generator that converts biomass (wood chips) into electricity and heat. It's designed to power mid-sized buildings, like schools or hospitals, and small communities with low energy demand. Below, one of the lead researchers demonstrates how it works:
Denmark uses a lot of biomass. As of now, biomass generation accounts for some 10% of its energy mix -- often in situations as those described above. Biomass is still controversial in green circles, due to the relative resource intensity inherent in such operations -- primarily, they use up a lot of water to grow fuel instead of food.
But the process is essentially carbon neutral (unless the biomass fuel needs to be transported over long distances), and provides a fine stopgap climate solution in many localalized situations.
