The CO2 Battery Plus technology, works alongside Open-Cycle Gas Turbines (OCGTs) and addresses three key areas:
Charge Mode
During low-demand hours or periods of excess renewable production, power is used to compress gaseous carbon dioxide, which is then stored in its liquid form in standard pressure vessels.
Discharge Mode (SuperBoost)
During peak-demand hours, the liquid carbon dioxide is evaporated and heated using heat from the gas turbine(s) exhaust(s), driving an expander and thereby running the CO2 Battery turbine, providing additional power comparable to that of an additional gas turbine of the same type, hence more than doubling its output (>100%).
Generation Mode (Boost)
The CO2 Battery compressor and turbine run simultaneously, with no net mass transfer between the gas and liquid carbon dioxide storage. The gas is looping in a closed cycle, increasing the net power output of the gas turbine by up to 25%.
While the global electricity demand accelerates, driven by AI workloads, hyperscale computing, and the rapid expansion of data centre infrastructure, the CO2 Battery technology provides cost-competitive, long-duration, and dispatchable energy storage that delivers firm, on-demand power at scale, enabling grids to meet this new load reliably without increasing emissions.
The CO2 Battery Plus unlocks a new level of performance by converting gas turbine exhaust heat into additional, on-demand power. In SuperBoost mode, it effectively adds the equivalent of another turbine, more than doubling output during peak demand. In Boost mode, it enhances efficiency in a closed-loop cycle, increasing net power by up to 25% without additional fuel input.
Unlike lithium-based systems, which only store and discharge electricity, CO2 Battery Plus actively amplifies generation, reduces fuel intensity, and leverages existing infrastructure. The result is lower delivered energy costs, greater operational flexibility to match data center load variability, and a materially reduced carbon footprint, all with infrastructure-scale reliability.
