Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

In a paper in Nature , they suggest that the use of such redox-active organic molecules instead of redox-active metals represents a new and promising direction for realizing massive electrical energy storage at greatly reduced cost. You could theoretically put this on any node on the grid. —Michael J. —Michael J.

California Hydrogen Business Council says a robust P2G RD&D program should be a priority for the state

Green Car Congress

P2G converts electrical energy to chemical energy in the form of hydrogen. The hydrogen can then be transported through the natural gas grid via blending or further conversion to methane, transported by other means such as trucks, or used directly at the point of production. Power-to-Gas concept. The duck curve.
