The world needs a large supply of renewable carbon to replace fossil feedstocks for hard-to-abate sectors like aviation, shipping, chemicals, food and beverage. Arno van den Bos, Karan Kochhar, Luis Janeiro and Francisco Boshell at IRENA present the results of their study to estimate demand, and whether supply can match it through to 2050. The main sources of supply come from alcoholic fermentation, biogas, pulp & paper, and biomass. Each has … [Read more...]
Turning Ethanol production’s CO2 by-product into E-Fuels using Wind power
With vast open spaces, Midwest states in the U.S. produce millions of gallons of ethanol from corn as well as thousands of kilowatt-hours of electricity from wind farms every year. Research led by NREL is working on using wind power to drive electrolysers that turn the ethanol’s CO2 by-product into e-fuels, explains Erik Ringle at NREL. A typical 50 million-gallon-per-year ethanol plant releases 14 tons of CO2, a natural by-product of … [Read more...]
