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. Currently, plants burning fossil fuels, primarily natural gas, fill in the gaps as peaker plants—a tendency that is likely to grow pari passu with VREs.

Air France KLM signs 210M gallon SAF offtake agreement with DG Fuels

Green Car Congress

The feed-stock reduction is achieved primarily by supplementing the process with oxygen and hydrogen produced by water electrolysis units that are powered by clean wind and solar generated electricity. DGF replaces the coal gasification used by others with biomass gasification and natural gas reforming.

Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

Wind and solar parks produce a large portion of their energy. Then, as now, wind farms are operating off the world’s coasts—but not all of these offshore sites are connected to the mainland via underwater power cables. Some of the wind farms instead sit in clusters more than 100 kilometers out at sea.

DLR team integrates solar heat into solid oxide electrolyzer for highly efficient hydrogen production

Green Car Congress

A team at Deutsches Zentrum für Luft- und Raumfahrt (DLR) has successfully integrated solar heat into a solid oxide electrolyzer. The experimental setup of the prototype system consisted of a solar simulator, a solar steam generator, a steam accumulator and a solid oxide electrolyzer. kW electrical power.

Berkeley Lab researchers advance hybrid bioinorganic approach to solar-to~chemicals conversion; 50% electrical-to-chemical, 10% solar-to-chemical efficiencies

Green Car Congress

A team of researchers at the US Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have hit a new milestone in their development of a hybrid bioinorganic system for solar-to-chemical energy conversion. In the new system, solar energy is used to split the water molecule into molecular oxygen and hydrogen.

Prometheus CEO outlines tech advances that could make CO2-to-fuels renewable gasoline and jet price-competitive with fossil fuels

Green Car Congress

Recent breakthroughs in separations and catalysis, along with long-trend reductions in solar and wind electricity costs, have significantly increased the potential for cost-competitive renewable fuels from direct air capture (DAC) of CO 2. TW of combined solar and wind capacity for the United States alone will be required.

Statkraft to install GE Rotating Stabilizers in grid-stabilization project in Scotland

Green Car Congress

GE Power Conversion will manufacture and install two Rotating Stabilizer synchronous machines at Statkraft’s site in Keith, Moray. Rotating Stabilizers can help reduce emissions and maintain grid performance by providing the same synchronous inertia as coal or gas power plants without the associated CO 2 emissions and high running costs.
