Bio-based phase change materials in lignocellulose matrix for energy storage in buildings. Acronym (BIO-NRG-STORE)

Energy consumption in residential buildings is one of the biggest energy-demanding sector and recent studies report that 40% of the energy generated in the EU is consumed in buildings.

Thermal-powered storage technologies have the potential to offer a flexible and reliable way to store heat by means of renewable, bio-based phase change materials (BFFM) encapsulated into lignocellulose matrix.

The project objective is to develop and validate insulation materials based on incorporated of BFFM into lignocellulose fibers, charcoal, veneer and solid wood aiming at increasing heat storage and conduction while retaining strength, increasing hygroscopicity, thermal insulation properties and improving biological durability of the initial materials.

Specific aim of the project is to use lignocellulose micro/macro structure (e.g. wood cell wall and lumen) as low-cost porous structures (storage cell) for encapsulation of BFFM for use in “green” building products for energy saving.
