2 Main feedstock - Biomass-based fuels (see Advanced fuels) Technologies covered - Grate, fluidized bed and pulverized combustion, gasification Main products - Heat, cool, power, process steam. In addition possible to produce bioenergy carriers (synthesis gas, bio-oil etc.) 2

3 European added value To develop advanced tri-generation concepts based on biomass as a major feedstock include the following added values - facilitating 100% renewable electricity market by enabling the integration of other renewables namely solar and wind power into biomass - decarbonising the heating and cooling sectors in combined electricity generation with/without energy storage - fulfilling the requirements of the energy efficiency and waste framework directives - meeting sustainability requirements by means of recycling of residues and minimising emissions 3

4 Main challenges Innovative components for trigeneration - < 10 MW e Local grid, local fuels - Bioenergy carrier production - High total efficiency with cooling load < 200 MW e Municipal grid, regional fuels Operation in a hybrid electricity/heating/cooling grid Energy storages > 100 MW e Regional grid, international fuels Regulating electricity production Energy storages and bioenergy carrier production 4

6 Key performance indicators - The total energy production efficiency can be doubled up by combined heating, cooling and power production (tri-generation) towards targeted value >80% as a average annual efficiency by 2020 from the current value for condensing power generation (36-37%). - The level of specific emissions will drop down to half compared to condensing power production. - One third of the target value in CO 2 reduction by 2050 (80%) can be reached by tri-generation production. 6

7 R&D activities needed Basic research (5 %) - Energy storage Applied research (15 %) - Concepts development for operation hybrid electric/heating/cooling grid Demonstration (80 %) - Demonstrations of trigeneration production in different scale by different technology (9 demos) 7

8 R&D budget needed for the value chain There s need for demonstration of tri-generation CHP-concepts in different scales and conditions shown in next slide - 1) medium-scale tri-generation at MW scale (industrial scale application). Three demonstration cases. Total funding needed for demonstration is 60 M + 30 M for research, follow up and dissemination activities. - 2) demonstration of tri-generation concepts at municipal scale ( MW with extended multifuel operation capability including. Three demonstration cases. Total funding needed for demonstration is 120 M + 30 M for research, follow up and dissemination activities. - 3) large scale demonstration of tri-generation 180M + 30 M 8

9 Main industrial actors - Investors, communities, power companies to develop new infrastructure to improve energy efficiencies in use of energy (RWE, Fortum, Vattenfall). - Boiler suppliers to develop new technologies and concepts for future energy markets (MW Power, Andritz, Ariterm Oy). - Business developers in energy sector. - Research institutes and universities (Sintef, VTT, Certh ). 9
