Flow Control Reliability and Optimisation

RheEnergise和国家工程实验室的合作项目。RheEnergise正在开发一种技术解决方案，其中高密度流体（水密度的2.5倍，大约是混凝土密度）可用于抽水蓄能应用，提高抽水蓄能项目的功率和能量密度。高密度流体意味着可以在海拔较低的地方找到场地（仅在英国就有约9,500），并且土木工程工作也减少了2.5倍。项目是闭环的，因此可以位于任何气候下，包括沙漠。该项目旨在确定高密度流体如何影响传统抽水蓄能应用中使用的阀门的长期运行和可靠性。如何通过了解通过阀门的流体流动特性，特别是静态流动领域(例如：天车)。对于RheEnergise（以及其他供应链中的英国企业）来说，潜在的机会是利用重力/机械解决方案，而不是仅仅依靠新兴的电池技术来实现未来的系统灵活性，在预计的全球能源存储和系统灵活性市场中占据很大比例（也许是10%）。RheEnergise已经确定有必要开展这项研究工作，以解决系统灵活性的巨大潜在市场：Aurora-Energy-Research预测，到2030年，仅在英国就需要60亿英镑，用于13GW的新灵活资产。彭博社-新能源财经预测2050年全球储能市场价值将达到6000亿美元。该项目的目标是使运营和成本效率提高10%，从而使RheEnergise能够实现其全球市场份额约10%的目标，这意味着在英国创新型公司的推动下，将为英国经济带来约60亿美元的直接效益。气候变化委员会、国家电网、英国能源、IPPR和许多其他评论员都表示，储能是实现净零碳能源系统所需的推动者。世界部分地区已经证明，可再生能源加上储能比煤炭、核能甚至天然气都要便宜。莱茵集团已放弃在德国开发新的煤炭项目。目前，英国和法国的海上风电合同价格低于40英镑/兆瓦时。全球许多地方的陆上风能和太阳能光伏的价格约为30.00英镑/兆瓦时。RheEnergise的GIS分析显示，英国约有9500个选址机会，欧洲（不包括北欧）约8万个，非洲约16万个。如果项目的平均规模为20MW/80MWh，那么仅需要350个英国站点就可以满足Aurora预计的英国2030年市场“需求”的50%。从过去10年风能和太阳能光伏装置的数量来看，在10年内建造350个站点是完全可以实现的。

A collaborative project between RheEnergise and the National Engineering Laboratory.RheEnergise are developing a technological solution where a high-density-fluid (2.5x the density of water, about the density of concrete) can be used in pumped energy-storage applications, increasing both the power and energy densities of pumped energy-storage projects. The high-density-fluid means that sites can be found in locations with lower elevations (~9,500 in the UK alone) and that civil engineering work is also reduced by 2.5x. Projects are closed loop and can therefore be located in any climate, including deserts.The project seeks to identify how the high-density-fluid affects the long-term operation and reliability of valves used in traditional pumped energy-storage applications. How maintenance costs can be minimised through understanding of fluid-flow characteristics through valves, in particular areas of static flow, (eg. trunnions).The potential opportunity is for RheEnergise (and other UK businesses in the supply-chain) to capture a large percentage (perhaps 10%) of the total predicted global energy-storage and system-flexibility market, using a gravitational/ mechanical solution rather than solely relying on emerging battery technologies for future system-flexibility.RheEnergise has identified the need to undertake this research work to address the huge potential market for system-flexibility:Aurora-Energy-Research forecast a £6bn requirement, in the UK alone, for 13GW of new flexible assets (2030). Bloomberg-NEF predict a global energy-storage market worth \>$600bn (2050).This projects goal is to enable a 10% increase in operational and cost efficiencies that in-turn enables RheEnergise to reach its goal of ~10% global market share, meaning ~$6bn of direct benefits to the UK economy, driven by a UK innovator company.The Committee-on-Climate-Change, National-Grid, Energy-UK, IPPR and many other commentators all state that energy-storage is the enabler required to achieve a net-zero carbon energy-system.Parts of the world have already demonstrated that renewable energy plus storage is cheaper than coal, nuclear and even gas. RWE has abandoned new coal development in Germany. Off-shore wind contracts are now <£40.00/MWh in UK and France. On-shore wind and solarPV in many locations globally is contacted ~£30.00/MWh.RheEnergise's GIS analysis shows ~9,500 UK site opportunities, ~80,000 Europe (ex. Nordics), ~160,000 Africa.At an average project size of 20MW/80MWh, only 350 UK sites would be required to provide 50% of Aurora's predicted 'need' for the UK's 2030 market. The numbers of wind-power and solarPV installations seen in the the last decade shows that the construction of 350 sites in a decade is entirely achievable.
