NREL ETES long-duration thermal energy storage – IMAGE ©NREL Four years ago, researchers at the National Renewable Energy Laboratory (NREL) won Department of Energy (DOE) ARPA-E funding to invent a new long-duration thermal energy storage technology able to discharge heat or power for 100 hours. The goal was to devise long-duration storage with a storage …

IRA incentives for thermal storage in idle oil wells IMAGE©Geo2Watts Climate policy in the US Inflation Reduction Act (IRA) provides powerful incentives to generate renewable energy and phase out fossil fuel production. Oil and gas companies are already required to cap boreholes when an oil well is depleted, to meet Asset Retirement Obligations (ARO). But …

Abstract Corrosion and dissolution of containment alloy constituents is an important consideration in high temperature thermal energy storage using molten salts. While the focus of most studies has been on protecting the alloys from corrosion attack, an often-neglected aspect is the dissolution of alloy materials into the molten salt which leads to fouling and possible …
