NextGenPower
NextGenPower is an integrated project which aims to demonstrate new alloys and coatings in boiler, turbine and interconnecting pipework. The concept of NextGenPower is to perform innovative demonstrations that will significantly contribute to the EU target to increase the efficiency in existing and new build pulverized coal power plants.
==Background==
Carbon Capture and Storage (CCS) is envisaged to be the main transition technology to comply with the CO2 reduction targets set by the European Commission.〔( NextGenPower Brochure )〕 However, CCS has the drawback that the electrical efficiency of the coal-fired power plant will drop significantly. The efficiency loss caused by CCS in coal-fired power plants will range from 4 to 12% points, depending on the CCS technology chosen.
To overcome this drawback, one has to increase the plant efficiency or the share of biomass co-firing. Both options are limited due to the quality of the current available coatings and materials. Live steam temperatures well in excess of 700°C are necessary to compensate the efficiency loss caused by CCS and to achieve a net efficiency of 45%.
NextGenPower aims to develop and demonstrate coatings and materials that can be applied in ultra-supercritical (in excess of 700˚C) conditions.
