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. California draws more than 20% of its electricity from solar and approximately 7% from wind, with more VRE coming online rapidly. —Drake Hernandez.

The ‘world’s largest’ ultra-high-altitude wind farm just came online in Tibet

Baua Electric

The world’s largest ultra-high-altitude wind farm came online on January 1 in Tibet, or what China now refers to as the Xizang Autonomous Region. The 100-megawatt (MW) wind farm is at an altitude of 4,650 meters (15,256 feet) in the Seni District. million wind farm was built in around 260 days despite the harsh conditions.

Compact pilot plant for solar to liquid fuels production

Green Car Congress

Partners from Germany and Finland in the SOLETAIR project are building a compact pilot plant for the production of gasoline, diesel and kerosene from solar energy, regenerative hydrogen and carbon dioxide. An electrolysis unit developed by Lappeenranta University of Technology (LUT) produces the required hydrogen by means of solar power.

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.

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.

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.

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. Hot steam with a maximum flow rate of 5.0
