New method could potentially produce hydrogen from biogas for $2/kg

Kore, an energy startup in California, has developed a new way to produce hydrogen from biogas, and is now poised to build a commercial-scale demonstration facility in Los Angeles. It said half of the carbon in the feedstock can be converted into gas, while the other half can be converted into solid elemental carbon char.

Module brands that earn the trust of solar installers

The latest global PV installer survey by Germany’s EUPD Research offers a hint of the solar brands which installers, mostly based in Europe, gravitate toward. This year’s report also ventured to South Africa and considered mounting systems for the first time.

The Hydrogen Stream: Acid-treated cells produce about 200% more hydrogen

US scientists have improved the performance of intermediate-temperature electrolyzers based on protonic ceramic electrochemical cells. Germany and India have signed a hydrogen cooperation deal, while ArcelorMittal has tested the use of green hydrogen in the production of direct reduced iron at a steel plant in Canada.

Laser focus on perovskite film formation

Scientists in the United States developed a method to observe the structure and mechanics of a perovskite material during its synthesis and transition from liquid precursors to a solid thin film. The group says its work will provide new insight into manufacturing and the development of reliable large-scale processes for perovskite solar cell production.

Strong potential for inorganic perovskites

Scientists in the United States have developed a method to compare the performance and number of defects in different perovskite cell materials. Based on simulations and work with prototype materials, the group finds that all-inorganic materials have higher potential efficiency than their more widely researched organic-inorganic counterparts.
