Efficient Thermal Systems
As the proportion of renewable thermal energy in heat networks increases, so will the need for new types of energy production, conversion, and storage components. In order to align intermittent renewable energy production with the dynamic demand of systems like heat networks, buildings, and industrial processes, modeling and simulating the systems and their components is the only way to ensure optimal management of the different sources of thermal energy.
Therefore, Liten focuses its research on innovative components like:
Liten has the capacity to integrate these components at different scales and to develop digital management tools validated on simulators that couple renewable energy sources and either urban heat networks or industrial processes. In terms of scaleup, Liten possesses test loops and demonstrator systems in actual industrial environments (the Calorie micro-network, the Multitherme demonstrator).
Residential buildings, which account for 40% of total energy consumption in France, are an integral part of Liten's energy research. Improving the performance of residential energy equipment is high on Liten's list of priorities. The institute tests new concepts on instrumented demonstrator buildings (the INCAS test houses, the FACT infrastructure) and on real buildings. To date, 200 occupied buildings are being monitored, providing valuable data on real-world usage that is used to improve control strategies.
Beyond heating networks, Liten makes use of CEA’s historic skills, which have been developed over 20 years on thermoelectric systems used for energy recovery, cooling and thermal monitoring applications. The work focuses on the development and characterization of materials (nanostructured thin films, bulk materials) and on the production of components and systems (thermal flow sensors in CMOS technology and for power components, micro energy harvesting).
Exponential growth in the number of sensors and other connected devices has made the Internet of Things, or IoT, virtually ubiquitous. And, not surprisingly, energy production, storage, and management—vital to keeping IoT devices running—are now top of mind.
Massive electrification is one of the keys to more environmentally sustainable energy practices—and one that will help us reach the target of reducing fossil-fuel consumption by half by 2050.
CEA-Liten and its partners have been looking at ways to optimize the management of urban heat networks for many years. Recently, they developed innovative algorithms and integrated them in a suite of software called DistrictLab-H.
