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

Green Car Congress

At modest current densities, round-trip energy efficiencies of 99% can be achieved. Short-term transients, including those related to wind and solar sources, present challenges to the electrical grid. Existing energy storage technologies cannot satisfy these requirements. Cost is a greater concern. —Wessells et al.

Australia Goes All-in on Green Hydrogen

Cars That Think

They’ve been studying up on renewable energy, hydrogen power, and electric vehicles, preparing for the big day in April when their remote-controlled vehicles will rumble for 4 hours in Gladstone, a port city in Queensland. And while coal plants still supplied over half of Australia’s power in 2021, change is afoot.

UC Davis researchers suggest we may be at the beginning of a real hydrogen transition in transportation

Green Car Congress

Key to realizing the potential role for hydrogen in transportation is automakers’ continuing commitment to hydrogen FCVs as a necessary complement to plug-in electric vehicles and a critical component of their long-term strategy to provide vehicles that contribute to energy and climate policy goals. Is it different this time?

How Smart EV Charging Will Help Promote Renewable Power Generation

Wallbox

The proportion of grid electricity generated by renewables such as wind and solar energy fluctuates depending on how hard the wind is blowing or how strong the sun is shining. This can lead to a huge variation in the grid power available, which can be a problem for power companies.
