Space-based Solar Power: A Great Idea Whose Time May Never Come

Cars That Think

The scene: A space-based solar power station called the Converter being commissioned some time in the Future. The plot: The astronauts are training Cutie to take over the station’s operations, which involve collecting solar energy in space and then directing it as intense beams of microwaves down to Earth. For example, U.K.-based

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.

PCC SE and Landsvirkjun to convert silicon metal plant CO2 emissions to methanol

Green Car Congress

The production of green methanol requires a renewable carbon source from PCC’s silicon metal plant in Iceland and renewable power from Landsvirkjun´s power stations. PCC SE aims for its silicon metal plant at Húsavík to become carbon-neutral by replacing fossil carbon reductants in production with renewable alternatives.

Bosch on importance of renewable synthetic fuels to reach climate goals; e-fuels

Green Car Congress

One path to achieving this is with renewable synthetic fuels (e-fuels). Bosch outlines seven reasons why renewable synthetic fuels should be part of tomorrow’s mobility mix: Time. Renewable synthetic fuels have long since left the basic research phase. emitted by burning renewable synthetic fuels is reused to produce new fuels.

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.
