The Corporate Rush for Long-Duration Storage

The demand for long-duration energy storage (LDES) is experiencing an unprecedented surge, driven largely by the aggressive climate commitments of major technology corporations. To power energy-intensive data centers with 24/7 carbon-free energy, tech giants are moving beyond short-term lithium-ion solutions and securing massive, multi-day storage contracts from innovative LDES developers.

Form Energy Secures Landmark 30 GWh Contract

In a landmark deal that underscores this market shift, Form Energy has contracted a massive 30 gigawatt-hours (GWh) iron-air battery project to supply a Google data center. This colossal agreement targets phased commissioning between 2028 and 2031. By leveraging iron-air technology, Google aims to bridge the gap between intermittent renewable generation and the continuous baseload power required for its AI and cloud computing operations, effectively shifting solar and wind energy across multiple days.

Energy Dome's CO2 Storage Pipeline

Simultaneously, Energy Dome is capitalizing on the corporate demand for alternative LDES chemistries. The company is advancing compressed carbon dioxide storage systems that achieve lower unit costs than lithium-ion batteries for 10-plus hour duration windows. Energy Dome's technology uses compressed CO2 gas in massive grid batteries, capable of delivering power for up to 24 hours to help balance renewable energy on the grid.

Energy Dome has secured project pipelines exceeding 30 GWh globally, including a dedicated facility in Ireland targeted for 2028 to support Google's European data center operations.

These monumental contracts signal a pivotal moment for the LDES market. Technology companies, with their vast capital and urgent decarbonization timelines, are acting as the primary catalyst for scaling novel storage technologies. By funding gigawatt-hour scale deployments of iron-air and CO2-based systems, the corporate sector is effectively de-risking these technologies and accelerating their path to global commercial maturity.
