DOE issues $35M funding opportunity for hydrogen and fuel cell technologies

Green Car Congress

One hydrogen production pathway that has not been included in recent funding opportunities is advanced high‐temperature water splitting (HTWS), including operation on renewable, low‐carbon electricity sources. For renewable, low‐carbon hydrogen production by HTWS, the energy source needs to be renewable with low‐carbon emissions.

BASF investigating sodium-air batteries as alternative to Li-air; patent application filed with USPTO

Green Car Congress

Their work, they suggest, demonstrates that substitution of lithium by sodium may offer an unexpected route towards rechargeable metal–air batteries. However, this system can also suffer from similar high overpotentials and low energy efficiencies when using carbonate-based sodium electrolytes. 1 (carbon), corresponding to roughly 3.3
