Renewable energy and Energy efficiency
Heat networks are generally set up by local governments to distribute heat generated at a central plant to residential, commercial, and government buildings. France’s current heat networks must be modernized if they are to meet the targets outlined in the country’s energy transition policies.
CEA Tech is helping to make heat networks more efficient, conducting research in areas like heat sources (and, especially solar thermal), cogeneration, and industrial waste-heat recovery. CEA Tech institute Liten is also investigating the heat storage systems crucial to managing heat networks fed in part by intermittent sources. Liten is developing simulation tools that will contribute to improving system-level performance and minimizing heat loss. The goal is to reduce the amount of heat production required while meeting the needs of users on a neighborhood scale.
ALL TECHNOLOGY PLATFORMS
Managing the intermittent nature of renewable energy production is one of the challenges to grid integration. CEA-Liten, a CEA Tech institute, developed a decision-assistance tool to optimize energy storage and ensure better grid regulation for a variety of time horizons.
A heating-network substation was commissioned in the lab for testing, and then upgraded to a more advanced version. Two testing platforms at solar energy research center INES were connected for the first time ever for the tests.
Several energy-related advances for the City of Grenoble, France were unveiled to the public as part of the CITY-Zen Days initiative. One of them is an innovative heating network. The prototype is currently under construction and the new network will round out France’s second-largest heating network.
Construction on the Jupiter 1000 power-to-gas demonstrator plant began on December 19, 2017 in Fos-sur-Mer in the South of France. The groundbreaking ceremony was attended by a number of elected officials. Research scientist Laurent Bedel of Liten, a CEA Tech institute, spoke to us about the project.
Liten, a CEA Tech institute, has developed a tool to predict concentrating solar power (CSP) plant production based on forecasts of direct solar irradiance.
How to collaborate with CEA Tech teams ?
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
