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. Schiller et al. A small fraction (0.58

BMW investing €400M in new vehicle assembly at Munich plant as part of shift to electromobility; engine production being concentrated at Steyr and Hams Hall

Green Car Congress

The plants will take advantage of the best options at each location—from solar energy in Oxford, Mexico and China, to biogas in South Africa, to wind power in Leipzig. In addition to using renewable energies, water, solvent, gas and electricity consumption will be further reduced in parallel.

Researchers develop new stable artificial photosynthesis device to produce ethylene and hydrogen from sunlight and CO2

Green Car Congress

By understanding how materials and devices transform under operation, we can design approaches that are more durable and thus reduce waste. Electron microscopy experiments at the Molecular Foundry confirmed that cuprous oxide quickly oxidizes or corrodes within minutes of exposure to light and water.

Texas: From Shale Boom to Water Revolution

Green Car Congress

Now the slick but dry state is becoming famous for water: that precious element that both resolves the drought problem and also makes it possible to pump more oil out of the ground. At the same time, the new technology uses no chemicals, rendering it quite possibly the ‘greenest’ water processing technology in operation today.

Thomas Built Buses achieves zero-waste-to-landfill

Green Car Congress

Thomas Built Buses, a subsidiary of Daimler Trucks North America LLC (DTNA), says it has become the first school bus manufacturer to achieve Zero-Waste-to-Landfill operations. Zero-Waste-to-Landfill means that everything received or produced by the company is used, reused, recycled or sold, and nothing is sent to the landfill.

Chilldyne optimized the cold plate using corkscrew-shaped metal channels, called turbulators, that force water around them “like little tornadoes,” maximizing the heat absorbed, says Harrington. Emily Waltz Mining leaves behind piles of waste after the commercially viable material is extracted.
