Micro Bio CHP

The aim of the project is to achieve an almost energy autonomous multi-family building with regard to space heating, domestic hot water supply, electricity consumption as well as electro-mobility.

This shall be achieved by integrating a novel and highly efficient biomass micro-CHP technology based on an updraft gasifier, a gas cleaning system and a solid oxide fuel cell (SOFC), a state-of-the-art PV system and appropriate innovative energy storage solutions.

This system shall not only satisfy the energy demands of the building but also distinguish itself by virtually zero emissions of CO, OGC and particulate matter and 55 % to 65 % reduced NOx emissions compared to other biomass-based CHP technology.

Description

The project aims at the development of an innovative RES-based system for heat and electricity supply in order to achieve an almost energy autonomous multi-family building with regard to heating and electricity consumption as well as electro-mobility. This shall be achieved by integrating a novel highly efficient biomass micro-CHP technology based on an updraft gasifier, a new gas cleaning system and a solid oxide fuel cell (SOFC), a state-of-the-art PV system and appropriate innovative energy storage solutions.

This system shall be economically highly attractive for future users and it shall also distinguish itself by virtually zero emissions of CO, OGC and dust as well as 55 % to 65 % reduced NOx emissions compared to other biomass CHP technologies. Consequently, it shall increase the penetration of RES on the multi-family house level and has the potential to significantly contribute to reaching the EU climate and clean air goals. The key innovations of the project are related to the novel micro-scale biomass CHP system.

They comprise a flexible partitioning of product gas supplied to the SOFC and to a gas burner in order to cover the overall heat demand and to maximize SOFC operation at the same time, a novel combined thermal and catalytic tar reformer, new highly efficient and durable stack units and a novel compact SOFC system with integrated HCl and H2S removal reactor. Based on a 2.5 kWel SOFC with an electric efficiency of 44 %, which is flexibly coupled with a 14 kW gasifier, overall efficiencies of more than 90 % shall be gained. A TRL of 5 shall be achieved at the end of the project.

The methodology applied to reach these goals relies on technology development tasks (based on process simulations, CFD aided design of the single units, test plant construction, performance and evaluation of test runs), a technology assessment part covering risk, techno-economic, environmental and overall impact assessments as well as targeted dissemination activities.
