Energy Dome product offering
Product offeringCore offering
Energy Dome designs, manufactures, and deploys grid-scale long-duration energy storage systems based on its proprietary CO2 Battery technology, which uses carbon dioxide in a closed thermo-mechanical compression cycle to provide 8-24 hours of firm, dispatchable electricity. The platform is offered in two configurations—the standalone CO2 Battery and the CO2 Battery Plus integrated with gas turbines—delivered through Energy Storage As A Service (tolling) or Buy Your Own Plant (direct purchase) commercial models for utilities, grid operators, and hyperscale data center operators.
Product overview
Energy Dome offers a unified CO2 Battery technology platform with two configurations. The core CO2 Battery provides 8–24 hours of standalone firm, dispatchable grid-scale capacity using a closed thermo-mechanical cycle with carbon dioxide. CO2 Battery Plus extends this by integrating with gas turbines to capture waste heat, achieving >115% efficiency and doubling peak output. These products are delivered through two business models: Energy Storage As A Service (tolling agreements with no upfront cost) and Buy Your Own Plant (full turnkey asset ownership).

Functional benefit
Products and services
- CO2 Battery Grid-scale long-duration energy storage system providing 8 to 24 hours of firm, dispatchable capacity using carbon dioxide as a working fluid in a closed thermo-mechanical cycle. Stores energy by compressing CO2 and dispatches it by expanding through a turbine to generate electricity, with 70%+ net round-trip efficiency and a 30+ year asset life. Designed for utilities, grid operators, and large energy users needing standalone capacity.
- CO2 Battery Plus Integrated configuration of the CO2 Battery that co-deploys with open-cycle gas turbines (OCGTs), using direct waste heat recovery to achieve >115% round-trip efficiency and more than doubling peak power output during SuperBoost mode. Turns existing gas generation into firm, long-duration capacity with lower delivered energy costs and a reduced carbon footprint. Purpose-built for AI data-center capacity programs.
- Energy Storage As A Service Service model in which Energy Dome finances, builds, owns, and operates a CO2 Battery plant while the customer enters a long-term tolling agreement to purchase energy storage capacity and dispatch services. The customer avoids upfront capital outlay, construction risk, and operating responsibility while receiving guaranteed performance.
- Buy Your Own Plant Turnkey delivery of a complete CO2 Battery plant—designed, engineered, supplied, and commissioned by Energy Dome—backed by an operational warranty and a long-term service agreement for maintenance and optimization. The customer owns the physical asset and is responsible for its operation.
