Energy Materials

The innovation domain of Energy Materials focuses on the development and application of advanced materials that can store sustainable energy in a sustainable manner. This interdisciplinary research area combines materials science, chemistry, physics, and technology to create innovative materials that enhance the efficiency, sustainability, and performance of energy systems.

Innovative developments in the innovation domain of Energy Materials focus on:

• Lithium-ion and alternatives: Lithium-ion and alternatives: new battery technologies such as sodium-ion, which are less dependent on critical raw materials.

• Electrolyzers: New designs such as solid oxide and AEM electrolyzers are in development alongside existing PEM and alkaline technology.

• Heat storage: Innovative methods such as latent and thermochemical heat storage utilize phase changes and chemical reactions.

• Nanomaterials and Thin Films: Used in energy storage and conversion, with applications in batteries and solar energy.

Refraining from the use of fossil energy sources requires sustainable, preferably circular alternatives. Promising are:

• Electricity: Battery technology, with applications in heavy transport, construction vehicles, and niche markets. Alternative storage methods, such as thermal batteries, are also being considered.

• Hydrogen: Production and storage of hydrogen through electrolyzers and fuel cells. The Netherlands can play an essential role in the value chain of electrolysis.

• Heat storage: Innovations in aquifer storage (underground storage in insulating soil layers) and heat storage tanks are essential for balancing energy peaks. This also offers export opportunities.
