Heliogen and Bloom Energy demonstrate production of low-cost green hydrogen; concentrated solar and high-temp electrolysis

Green Car Congress

Heliogen’s AI-enabled concentrated solar energy system is designed to create carbon-free steam, electricity, and heat from abundant and renewable sunlight. When combined with Bloom’s proprietary solid oxide, high-temperature electrolyzer, hydrogen can be produced 45% more efficiently than low-temperature PEM and alkaline electrolyzers.

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

Green Car Congress

The design permits larger amounts of energy to be stored at lower cost than with traditional batteries. But until now, flow batteries have relied on chemicals that are expensive or hard to maintain, driving up the cost of storing energy. Thus the amount of energy that can be stored is limited only by the size of the tanks.

Stanford team proposes new design strategy for electrolytes for lithium metal batteries

Green Car Congress

Stanford University scientists have proposed a design strategy for electrolytes that enable anode-free Li metal batteries with single-solvent single-salt formations at standard concentrations. In our study, we use organic chemistry to rationally design and create new, stable electrolytes for these batteries. Battery500.
