Study finds GWP of electrolyzed hydrogen to meet ORD’s fuel needs would be 2.5x that of fossil fuels with 2020 grid mix

Green Car Congress

His analysis found that if electrolyzed hydrogen were to be produced using a 2020 US electrical grid mix, its use would be associated with approximately 2.5x If only incremental increases in renewable energy resources are introduced across the grid, electrolytic hydrogen will not become an environmentally sustainable solution.

The source of the electricity – whether renewable sources like wind, solar, or water, or nonrenewable sources like coal – is also important. And while the energy grid is slowly becoming more “clean” as suppliers switch to renewable sources, business owners can also make a difference.

Mercedes-Benz Cars plants in Germany to be supplied with CO2-neutral energy from 2022

Green Car Congress

The production hall uses renewable energy and reduces water consumption and waste significantly. This includes optimized resource consumption through the most efficient use of energy and heat. On the roof of “Factory 56” there is a photovoltaic system which supplies the shop with self-produced green electricity.

Sandia study finds underground geologic storage of hydrogen could boost transportation, energy security

Green Car Congress

Additionally, installation of electrolyzer systems on electrical grids for power-to-gas applications, which integrate renewable energy, grid services and energy storage will require large-capacity, cost-effective hydrogen storage. Hard rock caverns are relatively unproven; only one site holds natural gas. Lord, Peter H.

IEEE Discusses 6 Simple Solutions to Climate Change at COP27

Cars That Think

Conventional coal-fired plants, which make water boil to generate steam that activates a turbine, have an efficiency of about 38 percent. Ultrasupercritical plants operate at temperatures and pressures at which the liquid and gas phases of water coexist in equilibrium. IEEE also launched a website that houses additional resources.
