Form Energy, Noon Energy and Ore Energy are all commercialising proprietary 100-hour battery technologies for LDES applications, but how do they compare on metrics like cost, energy density and round-trip efficiency? We look at what they have revealed, as well as what they haven't.

Hithium has signed a cooperation agreement for a potential 3GWh of battery storage deployments in the Asia-Pacific region with infrastructure investor Brawn Capital.

Form Energy has signed a 12GWh supply agreement in the US for its iron-air batteries with AI data centre infrastructure developer Crusoe.

Ex-Fluence alumnus Marek Kubik sat down with Energy-Storage.news at last month's Energy Storage Summit 2026 in London to talk big picture BESS technology trends, including energy density, LDES and sodium-ion.

Envision Energy's director of energy storage solutions, Michael Koller, speaks with Energy-Storage.news at Energy Storage Summit 2026 in London, UK.

Tesla and Chint Power rank first and second in a new long-duration energy storage leaderboard from Sightline Climate, while mechanical storage providers such as Italy’s Energy Dome feature prominently as post–final investment decision projects begin to reshape the competitive landscape.

From ESS News

An analysis of the long-duration energy storage (LDES) scene, focusing on technologies with at least eight-hour durations, shows the top two providers today globally are lithium-ion battery makers Tesla and Chint Power.

The new leaderboard by Sightline Climate, being developed over the past 15 months, according to the firm, gives a snapshot right now of leaders in LDES across factors including technology performance, financial profile, deployment track record, and economics and cost.

Lukas Karapin-Springorum, a research analyst at Sightline who introduced the LDES leaderboard to ESS News, said efforts to accurately rank players have been focusing on the core factors that matter to find the names that stakeholders like utilities, banks, and investors need to know right now.
