Gasifying the World to Save It

Gasification involves the flash heating of substances to above 1000 degrees Fahrenheit, in the absence of oxygen. Most of the yield is a combination of H2 and CO, referred to as syngas or sometimes “coal gas”. Any hydrocarbon can be gasified in that manner, including garbage, biomass, coal, shale oil, heavy oils, etc. Nexterra Energy of Canada has developed a process whereby syngas can be conveyed from where it is produced to another location for burning or use in synthesis of fuels. Nexterra has recently obtained new financing to allow it to scale up its process to service Canadian industries, including lime kilns.

Nexterra’s technology uses wood chips or other solid fuels to create relatively clean syngas, which can then be burned in a traditional gas power generation system. The feedstock is put through a tightly controlled series of steps including drying, pyrolysis, gasification and reduction, and in the end, the incombustible and dirty ash is removed and the hydrocarbon-rich syngas is piped away. The company is targeting plant-scale operations in the forest products, institutional, power generation and pulp and paper manufacturing sectors. _Source

Other companies are working on gasification of garbage and biomass, and others are using coal , oil shale, and heavy oils as feedstock.
