Water Horizon

Decarbonising the heating and cooling sector is central to achieve the energy transition. Energy for heating and cooling accounts for about 50% of the global final energy consumption in Europe and is responsible for more than 40% of global energy-related CO2 emissions.

Water Horizon has developed a mobile thermal battery able to recover unused waste heat (50°C-200°C) at one place and deliver renewable heating and cooling (-10°C- 50°) at another one.

The technology relies on thermochemical absorption to generate both cold and heat, with no thermal loss, high energy density, high efficiency, and easy control and modulation of the energy produced.

Our technology has been successfully demonstrated at industrial scale (1 MW) and is operating in Toulouse (France) : the battery recovers waste heat of an incinerator and delivers at the same time heat to a swimming-pool and cold to an ice-rink, both located 15 km away from the heat source.
