A High Efficiency Future Renewable Energy System - todays challenges - future solutions
Medarrangører: IDA Energi, Østjylland, IDA Miljø
Their integration to fluctuating electricity generation can be superior based on “stored sun” - presented by sustainable biomass developed through forestry around the world - like e.g. US south east, Africa etc.
Key note speaker
Prof. Dr.-Ing. Klaus Görner. Universität DuisburgEssen representing Rhein Ruhr Power highlights the challenges and perspectives of the future role for the large utility stations with respect to ramp figures, minimum loads/start up times, high temperature heat storage, oxyfuel and integrated methanol production etc.
The present world power systems are widely based on traditional coal fired, gas/oil and nuclear power stations while heating is based on oil, gas and in some countries electricity. In Denmark and Sweden widespread use of Combined Heat and Power (CHP) has resulted in large fuel savings reducing carbon footprint (CF) – also on fossil fuels – and the conversion of large units to biomass resulted in even lower CF.
Over the last decades wind and solar has developed – mainly through large subsidies and necessary grid
developments paid by the TSO’s. This wind/solar development results in reduced electricity market price. In Denmark and Sweden, the CHP units cannot compete on those terms. For new build the result is that even large new “power stations” are built at very modest electric efficiency or even only prepared for future electric generation as heat to district heating (DH) is more valuable in today’s picture – also twisted by taxation models.
Mitigation of transport carbon foot print is prioritized and has for long resulted in supported development and increased production of biofuels to be added to gasoline and diesel. Biofuels are regarded as the main road towards the future of trucking/Road haulage to lower the carbon emission. However – also at large primary energy conversion costs.
Systems to change road transport into being powered by conductive electric transmission combined with smaller battery packages are close to their break through challenging biofuel into trucking as the only option to lower transport carbon footprint.
The 45% net electric high efficiency “future” USC based power plant is already available e.g. at AVV2/Ørsted and can in combination with conductive based electric road transport lead to Well to Wheel efficiencies well above the possible best scenario for biofuels and hydrogen. It can also be the rapid ramping generation unit that fills in or reduces when the renewable power sources fluctuate. In oxyfuel mode such optimized units may
even be the basis for production of jet fuel/low emission marine fuel. Different systems involving gasification in
combination with electrolysis are being proposed as well as the oxyfuel “combustion” path. This conference day will focus on the pros and cons and with a view to the developments of electric traction of trucking.
