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. —Emre Gençer, co-author.

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.

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.

water and electricity to produce higher-energy carbon-based products and a co-product of pure oxygen. This reaction is energetically uphill, so electricity must be added to drive the reaction forward, and it is not possible without a new family of CO?-reducing reducing catalysts.

Study finds direct seawater splitting has substantial drawbacks to conventional water splitting, offers almost no advantage

Green Car Congress

For the implementation of a sustainable energy economy, the greatest challenge is the weather-depending, fluctuating electricity production of wind and solar power plants. To store the green electricity in a highly scalable way, it must be converted into chemical energy. Additionally, H 2 O is needed for water splitting.

CEMEX, Sasol and ENERTRAG partner to turn CO2 from cement plant into Sustainable Aviation Fuel

Green Car Congress

The consortium will source green hydrogen generated exclusively from wind and solar energy from ENERTRAG. In this first phase, 15,000 tons of electric kerosene are to be produced annually, from the 100 tons of CO 2 per day combined with 12 tons of hydrogen per day. All three companies are equal partners in the joint venture.

United announces investment in, commercial agreement with Dimensional Energy; CO2-to-SAF

Green Car Congress

Dimensional has also received grants from the National Science Foundation and both the Department of Energy’s ARPA-e and Solar Energy Technology Office (SETO). Dimensional’s technology can run on all forms of renewable energy. The company began construction on a CO 2 -to-fuels demo in Tucson, Arizona in 2021.
