Over the years, we put together a collection of information on wood gasification. What is wood gasification? Our friends at All Power Labs have put together a nice tutorial, and have provided us with a gasifier to experiment with. More documentation on that project is upcoming.
Gasification is the use of heat to tranform solid biomass or other carbonaceous solids into a synthetic “natural gas like” flammable fuel. Through gasification, we can convert nearly any dry organic matter into a clean burning, carbon neutral fuel that can replace fossil fuel in most use cases. Whether starting with wood chips or walnut shells, construction debris or agricultural waste, gasification will transform common “waste” into a flexible gaseous fuel you can use to run your internal combustion engine, cooking stove, furnace or flamethrower.
Did you know that over one million vehicles in Europe ran onboard gasifiers during WWII to make fuel from wood and charcoal, as gasoline and diesel were rationed or otherwise unavailable? Long before there was biodiesel and ethanol, we actually succeeded in a large-scale, alternative fuels redeployment– and one which curiously used only cellulosic biomass, not the oil and sugar based biofuel sources which famously compete with food.
This redeployment was made possible by the gasification of waste biomass, using simple gasifiers about as complex as a traditional wood stove. These small-scale gasifiers are easily reproduced (and improved) today by DIY enthusiasts using simple hammer and wrench technology. The goal of this GEK is to show you how to do it, while upgrading the engineering and deployment solutions to something befitting the digital age.
