Energy storage: the key to a decarbonised future

Setec Powerr

This article will answer your confusion. Technologies include energy storage with molten salt and liquid air or cryogenic storage. Molten salt has emerged as commercially viable with concentrated solar power but this and other heat storage options may be limited by the need for large underground storage caverns.

Gravity Batteries, Green Hydrogen, and a Thorium Reactor for China

Cars That Think

This article, by researchers at PARC and the University of Washington, is one possible answer. The basic idea is to add particles of sea salt to the atmosphere to brighten clouds and cool the planet. Molten salt nuclear reactors fueled by thorium were first investigated at Oak Ridge National Laboratory in the 1950s.

Researchers Propose Solar-Driven Biomass Gasification Pathway for Synthetic Fuel Production

Green Car Congress

High temperature heat for biomass gasification is obtained from a molten-salt system in a solar concentrating tower. One of the feasible approaches is heating sand (Olivine, also the catalyst of gasification reaction) by hot molten salt from a solar concentrator tower, using a gasifier designed as a fluidized-bed of olivine particles.

Sadoway and MIT team demonstrate calcium-metal-based liquid metal battery

Green Car Congress

MIT professor Donald Sadoway and his team have demonstrated a long-cycle-life calcium-metal-based liquid-metal rechargeable battery for grid-scale energy storage, overcoming the problems that have precluded the use of the element: its high melting temperature, high reactivity and unfavorably high solubility in molten salts.
