Value propositions

Take control of your load curves, from audit to market monetisation

Thermal storage coupled with processes

Ice tanks, buffer tanks or latent heat storage to shift thermal loads without affecting production. Peaks in cooling or heating demand are absorbed upstream, without oversizing installations or drawing on the grid at the wrong times.

Storage batteries (BESS)

Charging during off-peak hours, discharging at production or demand peaks: lower subscription costs, no more contract overruns, protection of processes sensitive to grid disturbances. Sizing based on the site’s actual load curve, not a catalogue standard.

Monetising flexibility

Participation in RTE demand response mechanisms and flexibility aggregators to monetise unused capacity. Storage assets are no longer just a cost control tool: they become a source of revenue.

Optimised control and BMS integration

Storage is controlled in real time and coordinated with all the site’s energy flows: renewable production, processes, lighting, HVAC. Optimisation is automatic and tariff arbitrage is calculated continuously.

Testimonial

“The waste heat emitted is equivalent to 100 nuclear reactors. To make use of it, we designed a disruptive technology in the form of a thermal battery that recovers lost heat.”

Chairman, Water Horizon

  • LOW-CARBON HEATING AND COOLING

    Port of La Rochelle

    With its ambition to cut carbon emissions by 30% by 2030, collaboration between waste heat producers and consumers represents a real opportunity for the La Rochelle area.

    The La Rochelle Energy-from-Waste plant (UVE) is a treatment centre for waste from local authorities and industry.

  • ENERGY STORAGE AND FLEXIBILITY

    Bessières greenhouses

    Recovery of waste heat from the Bessières energy-from-waste plant (196,000 t/year of waste) to supply renewable cooling to the Serres de Bessières greenhouses (10 ha, 6,000 t of tomatoes/year). LH2C (Low Heat to Cold) technology: charging and discharging on the same site. A local circular economy between a waste heat producer and an agricultural cooling consumer. Financing: Water Horizon + ADEME.

  • ENERGY STORAGE AND FLEXIBILITY

    Alex Jany sports complex, Toulouse Métropole

    World’s first industrial thermal battery commissioned (Sept 2025). Recovery of waste heat from the SETMI energy-from-waste plant (incinerator, 240,000 t/year of waste) transported to the Alex Jany swimming pool and ice rink complex. 2 thermal batteries of 1 MW. Financing: Water Horizon + European Commission (Innovation Fund €2.5M). Stakeholders: Toulouse Métropole, SETMI, European Commission.
