Researchers use quantum computing method to optimize molecular photoswitches for solar energy harvesting

Green Car Congress

Molecular photoswitches that can both convert and store energy could be used to make solar energy harvesting more efficient. Mikkelsen at the University of Copenhagen, (Denmark) and Kasper Moth–Poulsen at the Technical University of Catalonia, Barcelona (Spain), have taken a closer look at the photoswitches best suited for this task.

Danish team electrifies steam-methane reforming for greener approach to hydrogen production

Green Car Congress

Researchers from the Technical University of Denmark and Haldor Topsoe, with colleagues from the Danish Technological Institute and Sintex have developed a “ disruptive approach to a fundamental process ” by integrating an electrically heated catalytic structure directly into a steam-methane–reforming (SMR) reactor for hydrogen production.

New nickel-gallium catalyst could lead to low-cost, clean production of methanol; small-scale, low-pressure devices

Green Car Congress

Scientists from Stanford University, SLAC National Accelerator Laboratory and the Technical University of Denmark have identified a new nickel-gallium catalyst that converts hydrogen and carbon dioxide into methanol at ambient pressure and with fewer side-products than the conventional catalyst.

More details about California’s proposal requiring bidirectional charging capabilities for all EVs

Charged EVs

You could do V2G through the DC port of the vehicle—this is what we are doing with school buses here in California, where our charging station converts AC to DC and then connects to the DC port of the vehicle to provide power. Then it takes the DC from the bus, or car, and converts it back to AC to provide power for the grid.

New porous form of magnesium borohydride shows 2nd highest density among all known hydrides for hydrogen storage

Green Car Congress

Jensen at the University of Aarhus in Denmark report on a new highly porous form of magnesium borohydride in the journal Angewandte Chemie. The researchers made a third form, designated the ? Under high pressure this material converts into a nested, non-porous framework with a density that is nearly 80% higher.
