In the EMPOWER project a methanol fuelled 5 kWe mini-CHP system based on HTPEMFC technology is developed, manufactured and validated in a relevant environment. The system efficiency over 50% (DC, LHV) is achieved with novel ideas of thermal integration with a two-stage reformer setup and by using thermoelectric generators (TEG), utilising the high temperature heat of HTPEMFC stack. An aqueous phase reformer (APR) for methanol pre-reforming is applied for the first time in a commercial scale HTPEMFC system. The use of APR and its thermal integration in the FC system enables efficient utilisation of the stack waste heat and enables reformer efficiency approaching 95%. The best available catalysts will be screened and adapted for the reformer, both for the APR and for the 2nd stage reformer, which employs commercialised reformer technology from project partner Catator and recently developed methanol-reforming catalyst from partner University of Porto. The system efficiency is further improved by increasing the fuel utilization to above 95% in the HTPEMFC stack. This is enabled by improving anode gas flow distribution in the cells as well as improving the stack end plates. The new end plate design will also enable stack pressurising and improving stack efficiency over 55 %. The improvements in the HTPEM system design for mini-CHP use are validated in relevant environment, coupled to the heating and power system of a detached house, so that reliable data of the operation and stability can be generated. The accelerated test will be carried out for a period of 6 months and for at least 2,000 h of operation. Lastly, the project includes planning for scaling both the reformer solution and CHP system to 50-100 kWe size, including the addition of expanders. The technical work is complemented with a business analysis, including all the relevant elements of the methanol FC value chain, for the use of the developed technology in micro-CHP, CHP and maritime sectors.

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 maximise 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.

CBE4I aims at the development of a novel, fuel-flexible biomass updraft gasification based technology for a highly energy efficient, almost zero emission and zero waste process heat supply for flexible implementation at industrial settings satisfying the specific demands of industry. Low-value biomass residues which are available in large quantities shall be applied. CBE4I shall provide either (i) heat at different temperature levels which can be applied for indirectly heated processes via product gas combustion in an almost zero-emission gas burner with integrated three-way catalyst flexibly coupled with different boiler types (hot water, thermal oil, steam) or (ii) process heat and a clean product gas via product gas extraction with integrated thermal and catalytic tar reforming for utilisation in gas burners for direct heating. A novel flue gas condensation concept with directly coupled heat pump shall boost efficiency up to 120% (related to the NCV of the fuel). A newly developed condensate treatment shall allow for a direct discharge into sewers and regarding ash utilisation a new concept for application of biomass ashes in fertilizer production shall be developed. Moreover, CBE4I shall include the necessary fuel pre-treatment technologies and fuel logistics suitable for industrial sites. The latter comprise space saving on-site fuel logistics and on-line fuel quality assessment based on a new intelligent crane system. 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 assessments, LCAs, techno-economic, environmental and overall impact assessments as well as targeted dissemination activities. A market study shall investigate and define the framework conditions and application potentials of the CBE4I technology in different industrial sectors.
