Build to Zero is a Seville-based climate technology company founded in 2022, specializing in thermal energy storage technology for industrial heat decarbonization. Their mission is to transform industrial heat production to achieve a carbon-neutral future, phasing out fossil fuels while enhancing the competitiveness of manufacturing industries.
ThermalBox® is their flagship product — an innovative solution designed to replace fossil fuel boilers that combines power-to-heat technology with thermal energy storage. By utilizing direct electrical heating of a circuit of molten salts, ThermalBox® generates 100% decarbonized process heat in the form of steam or fluid. It provides 24/7 emission-free industrial heat below 400°C through electrification with renewables combined with thermal energy storage, and can be adapted to each process industry to economically substitute fossil fuels.
It primarily serves sectors such as chemical, petrochemical, food and beverage, paper and printing, and mining.
