UC Davis ITS researchers take a detailed look at water consumption and withdrawal requirements for ethanol

Green Car Congress

Water consumption intensity of ethanol from corn grain and crop residue and the avoided/displaced water use credits assigned to coproducts: DGS and electricity. In their paper, Mishra and Yeh analyze the lifecycle water requirement consumption and withdrawal requirements of ethanol produced from corn and from crop residue.

EIA: natural gas-fired reciprocating engines are being deployed more to balance renewables

Green Car Congress

In addition, power plants using internal combustion engines tend to require significantly less water than similarly sized combined-cycle or simple-cycle natural gas turbine plants. Power plants with large reciprocating engines are often located in states with significant renewable resources, specifically wind generation.

Researchers demonstrate sustainable integrated process for wastewater algae to biocrude via hydrothermal liquefaction

Green Car Congress

A team at the University of Kansas has demonstrated the feasibility of an integrated wastewater algae-to-biocrude process using hydrothermal liquefaction (HTL) that can sustainably cultivate algal biomass for biofuel production. HTL uses subcritical water as the chemical driving force to convert biomass to a carbon-rich biocrude.
