Researchers split water by altering photosynthetic machinery in plants; semi-artificial photosynthesis

Green Car Congress

A new study, led by academics at St John’s College, University of Cambridge, has used semi-artificial photosynthesis to explore new ways to produce and store solar energy. They used natural sunlight to convert water into hydrogen and oxygen using a mixture of biological components and manmade technologies. —Katarzyna Sokó?.

Energy storage: the key to a decarbonised future

Setec Powerr

We are transitioning from fossil fuels to renewable energy sources such as wind and solar, and the use of energy storage is becoming more widespread. Molten salt has emerged as commercially viable with concentrated solar power but this and other heat storage options may be limited by the need for large underground storage caverns.

Volkswagen inaugurates 9.5 MW solar park at Chattanooga plant in US; key element of VW Group’s strategic sustainability targets

Green Car Congress

MW solar park at Chattanooga is owned and operated by Silicon Ranch; VW has signed a 20-year power purchase agreement. Volkswagen inaugurated its largest solar facility in the world—also the largest solar facility operated by an automaker in the US—at its plant in Chattanooga, TN, which produces the Passat model for North America.

New TOTAL hydrogen filling station in Karlsruhe produces H2 onsite with steam electrolysis and solar energy

Green Car Congress

This H 2 filling station—the eleventh in the TOTAL network and the tenth in the German federal state of Baden-Württemberg—is differentiated by producing hydrogen on-site through steam electrolysis, using electricity generated by a solar array. By the end of 2018, 100 hydrogen stations will ensure a basic supply.

Monash team proposes roadmap to renewable ammonia economy; 3 generations of technology

Green Car Congress

Researchers at Monash University in Australia are proposing a roadmap to renewable ammonia being produced in the future at a scale that is significant in terms of global fossil fuel use. The H-B process is no longer required; instead, the reaction is driven by electrochemical reduction and the H source is water.
