THERMOBAT will develop an innovative Latent Heat Thermophotovoltaic (LHTPV) battery for long duration storage (10 to 100 hours) and combined heat and power (CHP) generation. The system stores electricity in the form of latent heat at very high temperatures (1200 deg C) using a new kind of ferrosilicon alloy with very high energy density (> 1 MWh per m3) and converts it back to electricity and low-temperature heat ( 400 kWh per m3), high global efficiency (> 90 %), that is safe, flexible, compact, silent, recyclable, scalable, and able to produce clean heat and electricity on demand. The dispatchable CHP generation capability of the LHTPV battery will be demonstrated in a sport center that is managed by one of the largest Spanish companies dedicated to the design, maintenance, and operation of infrastructures. THERMOBAT builds on the results (demonstrated proof of principle) achieved within the FET-OPEN project AMADEUS in which a small lab-scale prototype of the system was built and tested. THERMOBAT will bring LHTPV technology closer to commercialization by developing scalable, low-cost, and environmentally friendly processes for the manufacturing of the key components of the LHTPV battery. In addition, we will focus on accelerating tech-to-market activities through Thermophoton, a recently established UPM spin-off company that will receive UPM's know-how and will develop a detailed business plan to make the innovation fully marketable. This tech-to-market plan is also a continuation of another EU funded project named NATHALIE (FET Innovation Launchpad) in which the market and the potential application of the invention on industrial, commercial, and institutional buildings have been analyzed.

Effectively combating global warming requires a significant reduction in CO2 emissions. This poses enormous challenges, especially for the energy-intensive process and production industry, as this industry accounts for one third of total energy consumption. What is needed is intelligent electrification across all operational processes. Electrification has such a large potential impact on decarbonisation because it allows clean, renewable electricity to power processes that previously used emissions-intensive technologies (such as gas burners). This means that a process that previously produced high emissions can become absolutely emission-free when powered by renewable energy. The aim of the CITADEL project is to substitute fossil combustion processes with innovative electric technologies, such as electric resistance heating, microwave heating and plasma heating. Five use cases are considered, targeting the production of refractory bricks, glass and copper wires, preheating processes in steel production and the recycling of concrete. For these specific applications, appropriate demonstration plants have to be designed, built, tested close to the process and validated. This is supported by corresponding activities to provide suitable high-temperature materials and tools for instrumentation and effective process control. Challenges regarding a stable energy supply, electrical and thermal load management or intelligent energy management are simulated by means of numerical models. This includes corresponding risk assessments, e.g. with regard to possible time constraints in terms of a continuous power supply and the consequences of supply fluctuations for process safety. All demonstration cases will be evaluated by a life cycle analysis and with regard to the effectiveness in the reduction of greenhouse gases. The impact of the technical solutions developed here for the process industry will be assessed and strategies for scale-up and deployment will be elaborated.
