Sandy solution for renewable energy storage; Thermal Energy Storage System

Green Car Congress

Sand is emerging as a key ingredient in the race to develop a viable electricity storage system for renewable energies. Australia-based Latent Heat Storage has developed a low cost thermal energy storage system based on the latent heat properties of silicon derived from sand. —Jonathan Whalley.

Over the last five to 10 years we have seen an uptick in new entrants providing retail energy services," says Albert Cheung, head of global analysis at BloombergNEF. "It On any national grid, once the energy is in there, it's hard to trace the generating source—some of it will come from fossil fuels.

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

Green Car Congress

Researchers at Harvard have demonstrated a metal-free organic–inorganic aqueous flow battery—a quinone–bromide flow battery (QBFB)—as an example of a class of energy storage materials that exploits the favorable chemical and electrochemical properties of a family of molecules known as quinones. —Huskinson et al.

JRC study finds 8 metals for low-carbon energy technologies at risk of shortages; EVs, wind and solar, and lighting the applications of most concern

Green Car Congress

The study builds on a 2011 effort which looked into the six key applications of the Strategic Energy Technology (SET) Plan: wind, solar, nuclear fission, bioenergy, carbon capture and storage (CCS) and the electricity grid. The EU demand for lithium is projected at nearly 15% of the global supply, while that of graphite at 10%.

EKODA consortium exploring direct reuse or repurposing of batteries, gearboxes

Green Car Congress

If the energy storage system is older, it would be possible to use it in a smaller agricultural machine. Even if the battery has multiple defective cells, it may still be suitable for stationary use, for example, as electricity storage in a home photovoltaic system. The battery system does not need to be thrown away.

Roev’s electric ute plans explained: Conversions now, manufacturing its own vehicle by 2026

EV Central

The company is intending to create a so-called micro factory (possibly more than one) that would require much smaller capital investments to open the doors and be profitable churning out as few as 10,000 vehicles annually (most factories need to manufacture hundreds of thousands to be competitive globally).
