This calculator is provided for indicative feasibility purposes only. Results are based on simplified economic modelling and industry benchmark data and do not constitute investment advice. CAPEX benchmarks from Highview Power (2023), CryoHub EU H2020, NREL (2024), IEA. RTE reflects real LAES physics: liquefaction ~0.4 kWh/kWh; expansion recovery ~75%. Ancillary services revenue (frequency response, capacity market) is not modelled and may significantly improve project economics.
