Project

HYSOL

In the biobased economy biomass is used for conversion to biomaterials and bioenergy. Large part of this biomass comes from agricultural activities of which residues, such as crop residues and manure, are considered a promising source. Changing the use of these residues will affect the production conditions of agriculture and may have negative consequences for soil fertility and soil organic matter. Quantiative insight is lacking on where and how much residues can be used sustainably: knowledge which is needed to determine best practises on using agricultural residues for the biobased economy. Sustainable removal of agricultural residues and its consequences depends on crop and site characteristics and needs to be assessed in a spatial context for the development of the biobased ecocnomy.

In the EU HYSOL project a plant design is made for a solar energy plant making use of renewable gas to improve the efficiency of the use of the solar energy and to ensure a continuous electricity production while using only renewable energy. The potentials for the sustainable production of gas from biomass/residues for use in solar power plants need to be clear before this type of solar power plant can be introduced on a large scale.

The aim of this project is to give an overview of the potentials of biogas production from agricultural residues in the EU, the potentials of upgrading biogas to natural gas quality and the potentials to use the biogas production residues (digestates). Effects of residue and digestate use on soil organic matter and soil fertility will be assessed in a spatial context. This will be input to LCA scenarios performed by the Danish partner in the EU HYSOL project and can also be used by parties in the EU interested in biogas production.
