RWE AG , is a German electric utilities company based in Essen, North Rhine-Westphalia. Through its various subsidiaries, the energy company supplies electricity and gas to more than 20 million electricity customers and 10 million gas customers, principally in Europe. RWE is the second largest electricity producer in Germany. RWE previously owned American Water, the United States' largest investor-owned water utility, but this was divested in 2008. Subsidiary RWE Dea produces some of the oil and gas its parent sells and 3 billion m3 of natural gas . It is the largest German investor in Egypt . Also RWE has begun building more wind farms, a renewable energy business. Wikipedia.

In order to meet UK Government targets to reduce CO2 emissions by 80% by 2050, rapid growth in electricity generation from intermittent renewable energy sources, in particular, wind, is required, together with increasing constraints on the operation and environmental performance of conventional coal and gas-fired plant. Unprecedented demands for operational plant flexibility (i.e. varing power output to reflect demand) will pose new challenges to component integrity in ageing conventional plant, which it is widely recognised will play a crucial role in maintaining security of supply. In parallel, demands on fuel flexibility to reduce emissions, i.e. firing gas turbine plant with low-carbon syngas or biogas and firing/cofiring steam plant with biomass, will create new challenges in plant engineering, monitoring and control, and materials performance. Improved plant efficiency is a key requirement to cut emissions and to make decarbonisation economically feasible. The continuous development of novel, stronger high temperature materials may also enable component replacement, rather than complete new build plant, to maintain the essential reserve of conventional generation capacity. Finally, the decarbonisation transition involves new and complex economic and environmental considerations, and it is therefore important that these issues of sustainability are addressed for the development of future conventional power plant. The research programme will consider the key issues of Plant Efficiency, Plant Flexibility, Fuel Flexibility and Sustainability and how these four intersecting themes impact upon plant operation and design, combustion processes in general and the structural integrity of conventional and advanced materials utilised in conventional power plants. Outcomes from the proposed Research Programme include: - Improved understanding of the complex relationship between plant efficiency, fuel flexibility, plant flexibility, component life and economic viability - Novel approaches for monitoring and control of future conventional power plants - Improved fuel combustion and monitoring processes to allow use of a wider range of fuels - Improved understanding of structural materials systems for use in components with higher operating temperatures and more aggressive environments - Improved coating systems to protect structural materials used in power plant components - New models for optimisation of operating conditions and strategies for future conventional power plants The consortium comprises six leading UK Universities with strengths and a proven track record in the area of conventional power generation - led by Loughborough University, working together with Cardiff and Cranfield Universities, Imperial College London and the Universities of Nottingham and Warwick. The Industrial Partners collaborating in this project include several major UK power generation operators, Original Equipment Manufacturers (OEMs), Government laboratories and Small and Medium Sized (SMEs) companies in the supply chain for the power generation sector. The Energy Generation and Supply Knowledge Transfer Network will be a formal delivery partner of the consortium. The proposal has been developed following extensive engagement with the industrial partners and as a result they have made very significant commitment, both financial and as integrated partners in the research programme.

Method for operating a charging station for electric vehicles in which a charging power is negotiated between a charge control device of the electric vehicle and the charging station, the charge control device controls a charging current which is transmitted from the charging station to the electric vehicle in accordance with the charging power negotiated, wherein a continuous power rating and a maximum power of the charging station which is greater than the continuous power rating are determined. In order to optimise the charging power and to accelerate a charging operation, it is proposed that a charging power which is above the continuous power rating and which at most corresponds to the maximum power is first negotiated, that the temperature in the charging station be monitored, and that, when a limit temperature is exceeded, a new charging power which at most corresponds to the continuous power be negotiated.

Wind energy is a fast growing (>20% pa) industry worldwide and European companies have two-thirds of the share, according to European Wind Energy Association. Due to the increase in wind farms, new techniques are required to provide maintenance and inspection of the wind installations with reduced cost and enhanced reliability. It is estimated that the business opportunity for wind turbine blade inspection is at least 1bn per annum, and is increasing rapidly. In the DashWin project, a novel non-contact NDT system will be developed. It will consist of an advanced shearography kit and a robotic deployment platform. The system will be able to inspect the composite wind turbine blades (WTB) on-site without dismantling the blades, so that the degradation of WTB due to fatigue or natural incidents can be found before a breakdown or catastrophic failure occurs which is significantly better than existing systems. Objectives: Develop a novel shearographic system able to inspect WTB on-site without dismantling the blades. This will be the first time that a shearography system is used for inspecting a WTB in-service at a wind energy installation. The proposed concept and system is not limited to NDT of rotating WTBs, and can be extended to inspect other dynamic structures with large rigid body motion. Develop a wavefront splitter and/or a compact spatial carrier mask to achieve simultaneous spatial phase shifting. Integrate the shearography system with a robotics platform to carry out on-site inspections. Develop a comprehensive software package for image processing, automatic phase compensation, result interpretation and information storage. Validate the reliability of the new system and associated opto-mechanical set-ups through a stringent field trial test. System assembly and potential manufacturing routes will also be established. Develop and validate a new procedure for conducting regular inspection of WTB using the new robotic shearography system.

The intelligent and cost effective use of CCS technologies requires new strategies to increase the net efficiency of coal fired power plants. Among them, the most promising are summarised as below: - Increase working steam temperature and pressure in new USC power plants (350-370 bar, 700/720C minimum), and hence increase the severity of fireside operating conditions, - Promote clean coal technologies based (for example) on oxy-combustion \ co-firing technologies (by a continuous increase of biomass % in mixture with coal), in order to reduce CO2 capture losses and the amount of CO2 to be captured and stored. The project aims to increase the net efficiency of coal fired plants by increasing the performance and reliability of some critical components identified as follows: - refractory materials of the combustion chamber (especially for oxy-combustion application), up to 1800 C - headers and pipework (avoidance of weld Type IV cracking phenomena, working temperature increase), up to 650-660 C - super heaters (optimised performance in high temperature oxidation/hot corrosion environments), up to 720 C - coated pipes and boiler components able to withstand co-combustion conditions (high temperature oxidation/hot corrosion, erosion-adhesion and wear), - HP and IP steam turbine rotor components and turbine casing up to 750-780 C For each critical component, a full-scale prototype will be realised and installed into an industrial plant and/or in test loop(s) at known temperature, pressure and atmosphere conditions
