Imagine a giant thermal battery that uses melted salts to hold onto heat. It takes electricity from wind or solar when it's cheap and plentiful, stores it as heat, and then releases it as steam whenever a factory needs it. This means a plant can stop burning gas for heat even if the sun isn't shining or the wind isn't blowing.
Industrial plants rely on fossil fuels for steam and heat below 400°C because renewable electricity is intermittent. This creates high CO2 emissions and exposes companies to volatile natural gas prices.
A modular Power-to-Heat and Thermal Energy Storage system using molten salts. It includes a 2.5 MWth Basic Unit with two storage tanks, an electric heater, and a steam generator.
If you are a food processing plant dealing with high natural gas costs for steam production — this project developed a modular storage system that delivers steam up to 222°C. It allows you to switch from fossil fuels to renewable electricity while keeping a continuous heat supply.
If you are a chemical manufacturer dealing with rigid energy demands and volatile fuel prices — this project developed a 2.5 MWth Basic Unit that stores energy in molten salts. This enables you to decouple electricity purchase from steam usage to lower operational costs.
If you are a textile mill dealing with limited electrification options for your boilers — this project developed a Power-to-Heat solution capable of supplying steam up to 20 barg. It replaces fossil-fuel boilers with a clean, electrified alternative.
The project data does not provide a specific unit price, but it states the objective is to develop a cost-effective and optimized design for the small to medium industrial market.
The system is designed for small to medium industrial applications, with a target capacity of up to 5 MWth and a current focus on a 2.5 MWth Basic Unit.
Based on available project data, the technology is being developed by Build to Zero SL, but specific patent or licensing terms are not listed.
The system provides demand-side flexibility services to electricity system operators, allowing it to absorb renewable energy during peaks and release it as heat later.
The project runs from December 1, 2024, to November 30, 2026, focusing on manufacturing, installing, and testing the Basic Unit.
The project is led by a single Spanish SME, Build to Zero SL, which holds 100% of the industry ratio. This lean structure suggests a fast-track commercialization approach, focusing on the direct transition from a 2.5 MWth prototype to industrial production without the overhead of academic partners.
