The project aims at the development of a new fuel flexible and highly efficient residential biomass heating technology (20 - 130 kW). It is based on the successful UleWIN wood chip and pellet boiler concept consisting of a fixed-bed updraft gasifier directly coupled with a Low-NOx gas burner and a hot water boiler, which shall be further developed for fuel flexible operation (utilisation of forest residues, SRF, miscanthus, olive stones, nut shells and agro-pellets). Moreover, a compact flue gas condensation system with integrated condensate neutralisation, also capable to operate with highly acidic flue gases from agricultural fuel combustion, shall be developed to increase the efficiency of the whole system up to 110% (related to the fuel NCV). An advanced control system as well as measures for improved system integration shall additionally increase the annual utilisation rate up to 95%. It is expected to achieve at the end of the project a TRL of 5. These objectives are very relevant to the work programme since they focus on highly efficient and fuel flexible residential heat production at almost zero CO and OGC emissions, by 50% reduced NOx emissions (compared with conventional boilers) as well as ultra-low PM emissions below 13 mg/MJ (even when utilising K-rich fuels). Since this shall be reached by primary measures only, fuel flexible heat generation will be possible at reduced heat generation costs in comparison to present heating systems. To fulfil these goals an overall methodology shall be applied which is divided into a technology development part (based on process simulations, computer aided design of the single units, test plant construction, performance and evaluation of test runs) as well as a technology assessment part covering risk, techno-economic, environmental and overall impact assessments, market studies regarding the possible potentials for application of the new technology as well as dissemination activities.

It is high time for the EU to develop pathways and strategies for decarbonisation also in emissions intensive sectors such as steel, plastics, paper, and meat and dairy. These are sectors where low carbon transitions are still relatively unexplored. Some progressive companies and other actors are just beginning to consider such pathways. The overall aim of REINVENT is to help Europe achieve its long-term climate objectives, while supporting the development of other societal benefits and the economy. A new evidence-based framework to assess the viability, challenges and governance implications of decarbonisation pathways will be developed and tools provided. It builds on the integration of conceptual work, empirical mapping and case-studies of innovations and climate initiatives, co-creation of knowledge and co-design of pathways, and careful assessment of the implications for other societal goals. The approach is to study and understand transitions and emerging initiatives from within sectoral contexts where government climate policy is only one of many factors that shape perceptions and strategies. As a result, REINVENT supports systemic innovation and system-wide transformation in the studied sectors. The project provides stakeholders with access to leading research and analytical capacity concerning key dimensions of low carbon transitions; it is also a platform for dialogue and learning about feasible pathways so that policies can be better aligned with the specific needs and conditions in different sectors. REINVENT will make an innovative scientific and societal contribution through (a) focusing on important economic sectors that are relatively unexplored yet important for the whole economy, (b) studying transitions from within these sectors, and (c) taking whole value chains into account through (d) a new analytical approach capable of advancing our understanding of key drivers, dynamics and implications of decarbonisation.
