Cleanergy will plan and demonstrate (in phase 1 and 2) a solution for exploration and production of a technical solution that utilizes low-grade methane landfill-gas with a more efficient production of heat and electricity and better control of emissions from the combustion than existing technology. The combustion in the stirling engine application will be optimized. The project focuses on variations in the fuel which affect combustion and components. The challenge of Phase 1 refers to the varying gas composition and impurities. Research data shows that the gas composition and its compounds vary not only over time but also by season and weather. The project allows landfill-gas extraction to last long, be more predictable and stable and take care of pollution that would otherwise not be treated. In Phase 1 , we intend to identify various landfills where demonstrations can be made with different conditions and geography that reflects the market potential but also technical challenges. This way, we involve users in Phase 1 in order to better plan Phase 2. We will also examine if we need extra partners in Phase 2. A market survey will be conducted to know the proportion of landfills in Europe that have a gas collecting system and the landfills that flare. The flaring landfills represent the primary target in a first exploitation phase. A risk analysis will secure the measurements and method to be used in the demonstration phase in order to give valid results.In Phase 1 an innovation strategy will be developed and the European dimension will be refined. We will investigate potential obstacles for the company's ability to be profitable in the exploitation phase in order to secure the return on investment.Overall, the pilot will evaluate the feasibility of the concept and the idea for the project and innovation. The deliverable from phase 1 is a business innovation plan I.
