Iowa study suggests miscanthus would yield more biomass in Iowa soil than originally thought

Green Car Congress

Miscanthus, a perennial grass with vast potential to produce biomass, would deliver even better yields than once thought in Iowa, according to research by agronomists at Iowa State University. The paper found that the miscanthus hybrid had low mortality rates when faced with harsh Iowa winters. Nicholas N. Boersma, Emily A.

Iowa State team develops hybrid technology to create biorenewable nylon

Green Car Congress

Engineers at Iowa State University have developed a hybrid process that combines bio- and electrocatalysis to convert glucose into bio-based unsaturated nylon-6,6—which has the advantage of an extra double bond in its backbone that can be used to tailor the polymer’s properties. Their study is published in the 12 Feb. Suastegui et al.

USDA provides $91M loan guarantee to Cool Planet for biogasoline blendstock plant; biomass pyrolysis and catalytic conversion

Green Car Congress

A precise amount of ground biomass is fed into a moving tray; at the first heating and processing stage, the function is to drive off entrapped water, and to perform the first step of de-hydration of the biomass while mechanically compacting it for more effective heat transfer at later stages of processing. Depending on the temperature (300

Departments of Energy and Interior award nearly $17M for advanced hydropower technologies

Green Car Congress

By allowing utility operators to pump water up to a dam or impoundment during periods of low electricity demand and release water during times of peak electricity demand, pumped storage hydropower improves the reliability of electric grids and helps increase the use of variable renewable energy resources such as wind and solar power.
