Gasification to produce electricity is becoming m

Gasification to produce electricity is becoming more and more popular all the time. Lots and lots of information can be found out about gasification. Below is some information. I believe the thing we need to realize about this Is, since gasification is a viable way to produce electricity and with it becoming more popular GESI will and does have high growth and expansion possibilities just for being in a growing industry. With that in mind once GESI completes permitting and builds the first plant how many more will follow?

“Biomass gasification works just like coal gasification: A feedstock enters a gasifier, which cooks the carbon-containing material in a low-oxygen environment to produce syngas. Feedstocks generally fall into one of four categories:

•Agricultural residues are left after farmers harvest a commodity crop. They include wheat, alfalfa, bean or barley straw and corn stover. Wheat straw and corn remnants make up the majority of this biomass.

•Energy crops are grown solely for use as feedstocks. They include hybrid poplar and willow trees, as well as switchgrass, a native, fast-growing prairie grass.

•Forestry residues include any biomass left behind after timber harvesting. Deadwood works well, too, as do scraps from debarking and limb-removal operations.

•Urban wood waste refers to construction waste and demolition debris that would otherwise end up in a landfill. Pallets -- flat transport structures -- also fall into this category.

The choice of feedstock determines the gasifier design. Three designs are common in biomass gasification: updraft, downdraft and crossdraft. In an updraft gasifier, wood enters the gasification chamber from above, falls onto a grate and forms a fuel pile. Air enters from below the grate and flows up through the fuel pile. The syngas, also known as producer gas in biomass circles, exits the top of the chamber. In downdraft or crossdraft gasifiers, the air and syngas may enter and exit at different locations.”
