The aim of greenGain is to strengthen the energy use of regional and local biomass from the maintenance of areas and landscape elements, which is performed in the public interest. The scope of the biomass used, will be any material predominantly produced from nature conservation and landscape management, but not from energy-crops. The main target groups are regional and local players, who are responsible for maintenance and conservation work and for the biomass residue management in their regions. Moreover, the focus will be on service providers - including farmers and forest owners, their associations, NGOs and energy providers and consumers. The project will show strategies to build up reliable knowledge on local availability of these feedstocks and know-how on issues from logistics to storage and sustainable conversion pathways for the transformation of these feedstocks to renewable energy (heat and energy products). Furthermore political, legal and environmental aspects will be addressed in model regions. Awareness raising, governance and public acceptance actions will be focussed on. General guidelines will be prepared to guarantee a wide dissemination to other regions in the EU. The regional partners will be actively supported by Technical Partners for the project measures’ development and implementation. As a CSA, the project focal point will be the exchange between the model regions and other similar relevant players in the EU, by good practice exchange, a topic-specific website, several workshops and educational site visits in different regions as well as other standard public relations activities. The project team is carefully balanced between technical and scientific organisations and local demand side oriented players. Regions in northern Europe with a wide knowledge in this field are cooperating with European (south-west, middle, east) regions, having an untapped potential, that can be accessed through efficient knowledge transfer.

The GreenSolRes project demonstrates the levulinic acid (LVA) value chain of lignocellulosic feedstocks to high-value products in a 3-step approach on TRL 6. First, a demonstration plant in Biorefinery of RWTH Aachen will be designed and build for conversion of lignocellulosic biomass to the platform chemical levulinic acid. Levulinic acid hydrolysate separation enables more efficient and purer levulinic acid production. In a 2nd step the versatile platform chemical levulinic acid is hydrogenated to 2-methyltetrathydrofuran (2-MTHF), gamma-valerolactone (GVL) and 1-methyl-1,4-butanediol (MeBDO) in a direct process developed by RWTH Aachen. These can be produced in the same reactor with a single catalyst by tuning the process conditions. In parallel, BASF will investigate the conversion of LVA esters to MeBDO and GVL. Third, the application of the products as solvents is validated in adhesives and the pharma sector as substitute of their less sustainable C4-analogues. Additionally, HENKEL studies the development of respective new polymers with improved properties. The basic engineering of first commercial plants for these steps supports rapid upscaling and exploitation after the project. This will release these products from the niche markets they are confined to due to ineffective existing production routes. At competitive prices compared to their petrochemical C4-counterparts these chemicals and related products will boost the bio-based market as they have a high greenhouse gas emission avoidance of at least 70% and an additional value to society via better health & safety properties. The whole value chain from e.g. forestry residues to consumer products is assessed for environmental sustainability, risks and health & safety to support business case development and market implementation.

Photofuel studies and advances the biocatalytic production of alternative liquid transportation fuels, which require only sunlight, CO2 and water. Microbial cells directly excrete hydrocarbon and long chain alcohol fuel compounds to the medium from which they are separated, without the need to harvest biomass. This significantly improves the costs and energy balances as only a minimum of nutrients is required for self-replication of the biocatalyst, whilst cell harvesting, drying and lipid extraction is omitted. Such minimum-input systems are compatible with operation on degraded or desert land which avoids the pitfalls of most of the currently available biofuel technologies. The products are drop-in fuels that fully or partially replace their fossil counterparts without the need for new infrastructure. To set a benchmark for alternative solar fuels, three research groups will collaborate in the advancement of the biocatalysts from TRL 3. The best biocatalytic system(s) will be up-scaled and operated outdoors in photobioreactors modified for direct fuel separation at a scale of several cubic meters (TRL 4-5). The identification of optimal future fuel blends with a fossil fuel base and Photofuel biofuels as additives, as well as the analysis of performance and emissions in car or truck engines, will be evaluated by the oil- and automotive-industry partners. The entire pathway will be assessed for environmental and economic performance as well as social acceptance of large scale production in rural communities and by the consumer. All results will be combined to a business development plan, which clearly identifies the opportunities but also the challenges prior to an economic fuel production in compliance to the EC Fuel Quality Directive.
