Energy Dome and digital infrastructure company New Era Energy & Digital Inc. (NUAI) have signed a Memorandum of Understanding (MOU) to assess deployment of Energy Dome’s CO2 Battery Plus system at NUAI’s Texas Critical Data Centers (TCDC) campus in Odessa. The project is designed to support a planned 1 GW+ AI‑optimised data centre, where reliable, dispatchable power is critical amid grid interconnection constraints and soaring computing‑driven demand.
The partnership focuses on using the CO2‑based storage technology to maximise speed to power, reduce dependence on constrained grid upgrade timelines, ensure high availability for mission‑critical operations, and lower the carbon intensity of on‑site generation. Energy Dome’s CO2 Battery Plus system integrates with open‑cycle gas turbines (OCGTs), capturing waste heat from turbine exhaust and using it during discharge to boost output and efficiency, effectively achieving performance closer to a combined‑cycle setup at lower capital cost.
The system can operate in three modes: charge, where CO2 is compressed and liquefied during low‑demand or high‑renewable periods; discharge (SuperBoost), where the stored CO2 is re‑expanded using turbine exhaust heat to deliver extra power equivalent to an additional gas turbine; and generation (Boost), where the compressor and turbine run together to increase net turbine output by up to 25% without net mass transfer.
Energy Dome says the technology addresses the mismatch between highly variable AI data centre loads and on‑site generation, while helping to cut delivered energy costs and emissions. NUAI plans to expand the deployment across its digital infrastructure portfolio, noting that the company’s recent collaborations with hyperscalers underline growing recognition of the platform in the AI‑driven power market.
