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. As we move to more and more renewable penetration, this intermittency will make a greater impact on the electric power system. —Drake Hernandez.

Bauhaus Luftfahrt analysis finds solar thermochemical jet fuel production viable only if CO2 captured from renewable sources and not flue gases

Green Car Congress

A team from Bauhaus Luftfahrt in Germany has analyzed the climate impact and economic performance of solar thermochemical jet fuel production. Schematic of solar thermochemical fuel production path. A solar tower or dish concentration system can deliver the required level of radiative flux. kg CO 2 ‐equiv /L. Click to enlarge.

Solar-to-Jet-Fuel System Readies for Take-Off

Cars That Think

A glimmer of hope, however, comes from solar fuels. For the first time, scientists and engineers at the Swiss Federal Institute of Technology (ETH) in Zurich have reported a successful demonstration of an integrated fuel production plant for solar kerosene. They also reported good material stability for multiple consecutive cycles.

Berkeley study finds renewable portfolio standards insufficient to meet 2030 GHG emission targets; new policy required

Green Car Congress

The least expensive way for the Western US to reduce greenhouse gas emissions enough to help prevent the worst consequences of global warming is to replace coal with renewable and other sources of energy that may include nuclear power, according to a new study by University of California, Berkeley, researchers. —Daniel Kammen.

Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

Benson from Stanford University and Stanford’s Global Climate and Energy Project (GCEP) has quantified the energetic costs of 7 different grid-scale energy storage technologies over time. The Stanford study considered a future US grid where up to 80% of the electricity comes from renewables. Click to enlarge. A new study by Charles J.

Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

Jacobson, who is also a senior fellow at the Stanford Woods Institute for the Environment, examined public data from a coal with carbon capture and use (CCU) plant and a synthetic direct air carbon capture and use (SDACCU) plant for the equipment’s ability, alone, to reduce CO 2. You can’t just ignore health costs or climate costs.
