Heating Buildings With Solar Energy Stored in Sand

Cars That Think

When we turn up the heat in our homes and workplaces, we must balance our personal need for warmth with the global impact of burning fossil fuels like oil, gas, coal, and biomass. These initiatives have largely focused on renewable electric power generation, distribution, and storage. The apparent contradictions do not end there.

BNEF report finds hydrogen promising decarbonization pathway, but carbon prices and emissions policies required

Green Car Congress

The falling cost of making hydrogen from wind and solar power offers a promising route to cutting emissions in some of the most fossil-fuel-dependent sectors of the economy, such as steel, heavy-duty vehicles, shipping and cement, according to a new report from BloombergNEF (BNEF). Storing and moving hydrogen is challenging.

5 Big Ideas for High-Temperature Superconductors

Cars That Think

In 1911, Dutch physicist Heike Kamerlingh Onnes plunged a mercury wire into liquid helium and noticed that the wire’s electrical resistance vanished. It refers to materials that superconduct above −195.79 °C, the boiling point of liquid nitrogen. HTS induction heaters promise to halve energy use, along with greenhouse gas emissions.

Audi unveils e-gas project: synthetic methane from the methanation of green hydrogen; series production of CNG models in 2013 powered by e-gas

Green Car Congress

Audi A3 TCNG for e-gas project. Starting in 2013, Audi will begin series production of TCNG models whose engines—derived from TFSI units—will be powered by e-gas: synthetic methane produced via the methanation of hydrogen produced by electrolysis using renewable electricity. Click to enlarge.

AQDSH 2 refers to the reduced form of AQDS. Quinones are naturally abundant, inexpensive, small organic molecules, and similar to molecules that store energy in plants and animals. Solid-electrode batteries maintain discharge at peak power for far too short a time to fully regulate wind or solar power output. Cell schematic.

What is Renewable energy integration, challenges, why it is needed

Baua Electric

Renewable energy integration refers to the process of efficiently incorporating renewable energy sources into existing energy systems. This involves the seamless blending of renewable energy, such as solar, wind, hydro, and geothermal power, into the overall energy infrastructure to meet the growing demand for clean and sustainable energy.

“Project Volt Gas Volt” proposes long-term financing plan to support widespread implementation of power-to-gas systems

Green Car Congress

Project Volt Gas Volt is based on a long-term financing plan and the use of existing technologies for the large-scale conversion of surplus renewable electricity to methane, with subsequent reuse. Project VGV uses surplus electricity generated by renewable and nuclear sources to produce hydrogen via electrolysis. Earlier post.).
