Heineken Spain
Valencia
The solar thermal plant installed at Heineken’s factory in Valencia was developed to reduce CO2 emissions and promote renewable energy use in industrial processes. It uses Fresnel technology to produce steam at 8 bars, which Heineken uses in beer production. The main goal was to help Heineken achieve 100% renewable energy. The system, covering 6,000 m² with 182 Fresnel modules, generates about 4.2 MW of thermal power. Completed in eight months thanks to its modular design, it reduces reliance on natural gas, cutting emissions by around 1,300 tonnes annually. The installation also contributes to local industry, involving Spanish components and creating over 160 jobs. This project addresses the dependence on fossil fuels, lowers energy costs, and advances Industry decarbonization. It operates under a 15-year Power Purchase Agreement (PPA) and is part of public-private collaboration supported by European funds. It is the biggest Fresnel plant for industrial processes in the world.
The solar thermal system saves about 1,300 tons of CO₂ annually by replacing fossil fuel steam and reduces natural gas use, decreasing emissions. It involves a €3 million investment. Since it's a PPA contract, Heineken does not have direct ROI but benefits from purchasing energy at a competitive price compared to natural gas costs, ensuring long-term energy savings and environmental impact reduction.
Solatom produces renewable energy heat by concentrating solar energy with mirrors that track the sun. This energy is concentrated into a receiver - an isolated vacuum tube absorber - where steam, hot oil or hot air is produced. Thanks to this heat, Solatom not only manages to reduce the industry’s CO2 emissions, but it also manages to reduce the client’s energy bill. This reduction in price is possible thanks to its innovative design, which allows the solar energy to be converted directly into heat, rather than producing electricity first, to later produce heat. Another big advantage of Solatom’s product is the high temperature (up to 350 ºC) it can reach. Many industries demand high temperatures, and conventional solar flat plate collectors are just not able to generate heat at temperatures over 120 ºC. This is because flat plat collectors do not track the sun to concentrate the energy, which limits its use to households and not solving the industries problem, like Solatom does.
