MITEI study finds hydrogen-generated electricity is a cost-competitive candidate for backing up wind and solar

Green Car Congress

A team at MITEI (MIT Energy Initiative) has found that hydrogen-generated electricity can be a cost-competitive option for backing up wind and solar. However, the authors noted, the power prices required to justify investment in an HFGT to replace a natural gas-fired gas turbine are considerably higher than those seen in the market today.

Study: Energy sorghum may combine best of annual, perennial bioenergy crops

Green Car Congress

Now, a study by researchers at the US Department of Energy (DOE) Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) has found that energy sorghum ( Sorghum bicolor ) behaves more like miscanthus in the way it efficiently captures light and uses water to produce abundant biomass. Energy sorghum falls somewhere in between.

Separate MIT, IEA reports both outline major expansion in role of natural gas; caution on climate benefits

Green Car Congress

World primary energy demand by fuel in the IEA high gas scenario. Separately, the International Energy Agency (IEA) released its own report exploring the potential for a “golden age” of gas. Both reports also emphasized that although natural gas is the lowest carbon fossil fuel, it is still a fossil fuel. Source: IEA.

China Will Attempt First Carbon-Neutral Winter Olympics

Cars That Think

About 160 kilometers northwest of Beijing, the city of Zhangjiakou with its rugged terrain boasts some of the richest wind and solar resources in China. Renewables account for nearly half of the city’s electricity output with less than a third of its full solar and wind potential of 70 gigawatts installed so far.
