DOE to award up to $180M for offshore wind demo projects; targeting lowering levelized cost of energy (LCOE) below 10¢/kWh

Green Car Congress

The US has offshore wind resources estimated at more than 4,000 gigawatts, with strong, consistent winds located in the Atlantic, Pacific, the Great Lakes and the Gulf of Mexico. LCOE is the sum of all annual costs divided by the amount of electricity produced per year.). Funding is subject to Congressional appropriations.

Japan team evaluates battery-assisted low-cost hydrogen production from solar energy

Green Car Congress

Researchers from Japan’s NIMS (National Institute for Materials Science), the University of Tokyo and Hiroshima University have jointly conducted a techno-economic analysis for hydrogen production from photovoltaic power generation (PV) utilizing a battery-assisted electrolyzer. This approximately converts to US$1.92 to US$3.00/kg

Fraunhofer analysis finds battery-electric trucks have energy cost advantage over hydrogen trucks

Green Car Congress

The energy cost advantage of battery-electric trucks is the key to a rapid switch to e-trucks, because fuel and energy costs account for the largest share of the total cost of ownership (TCO) for intensively used commercial vehicles. They exceed the purchase costs many times over.
