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

Phil Ansell, an aerospace engineer at the University of Illinois Urbana-Champaign, modeled the life cycle carbon dioxide equivalent emissions of liquid hydrogen production required to meet the fuel needs of Chicago’s O’Hare International Airport (ORD) with today’s electric grid mix.

Power-to-gas trial to inject hydrogen into Australia’s gas grid; A$5M award to AquaHydrex

Green Car Congress

The Australian Renewable Energy Agency (ARENA) announced a trial for a new type of electrolyzer which could see excess renewable energy stored in the gas grid and used to decarbonize Australia’s gas supply. When hydrogen burns, it produces only water vapor and no carbon dioxide.

DOE awarding $35M to 11 projects for hydrokinetic turbine development; ARPA-E SHARKS

Green Car Congress

Hydrokinetic energy is an abundant renewable resource that can boost grid resiliency and reduce infrastructure vulnerability, but it is currently a cost prohibitive option compared to other energy generating sources. The University of Michigan. The turbine will be designed for power delivery to remote and local grids.

New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Yi Cui has developed nanoparticle copper hexacyanoferrate (CuHCF) battery cathode materials that demonstrate long cycle life and high power for use in grid storage applications. Short-term transients, including those related to wind and solar sources, present challenges to the electrical grid. A team at Stanford led by Prof.

Bloom Energy announces hydrogen-powered energy servers to make always-on renewable electricity a reality

Green Car Congress

At peak times, some US states and countries already have more renewable power than their grids can handle. Despite those periods of excess wind and solar power, because the ability to store electricity for more than a few hours is lacking, dispatchable power from the combustion of fossil fuels continues to bridge gaps in supply.
