CO2-neutral hydrogen storage with a bicarbonate/formate system

Green Car Congress

Here, we describe for the first time the design of a reversible hydrogen storage cycle based on the redox system bicarbonate/formate. Most importantly, after full conversion of the formate, the bicarbonate solution may be recharged with hydrogen to close the cycle. Angewandte Chemie International Edition doi: 10.1002/anie.201101995.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

The battery in her EV is a variation on the flow battery , a design in which spent electrolyte is replaced rather than recharged. The design returned to life in the mid-20th century, was developed for possible use on a moon base, and was further improved for use in grid storage.
