Dutch industry, which accounts for more than 40% of energy consumption, relies heavily on heat produced by burning fossil fuels. The necessary transition to renewable energy sources, together with rising costs for CO2 emissions, poses a significant challenge. The desired electrification of heat production by alternatives is lagging behind. Increased electricity consumption, estimated at 80 to 130 terawatt hours by 2050, requires flexible energy solutions to address the mismatch in supply and demand, which causes grid congestion and fluctuating energy prices. In this project, a molten salt heat battery system is developed, demonstrated and validated, which can deliver industrial steam between 100-400°C. This system is aimed at saving energy and reducing grid congestion in industrial environments. Participating parties are Brabetech and Gielissen Technical Companies. This is validated at Bio Energie Centrale Cuijk.
