Second Life SaaS (Storage as a Service); the resource efficient, mass-market home energy storage solution

政府已承诺到2050年实现温室气体净零排放，但已经偏离了实现其2020年可再生电力目标（CCC）的轨道，即家庭占排放量的40%。同时，家庭和企业面临着越来越多的能源账单，因为我们减少了运输和供热，到2050年，成本将达到400亿英镑，而灵活的能源资产无法缓解。可再生能源（RE）受限于缺乏灵活性的电网无法处理可变供应，以及在Covid-19期间因供应过剩而引入昂贵的新限电措施（5亿英镑）。最后，伯明翰大学、IET和IEA的数据显示，到2040年，全球将有3000万至6000万吨废旧电动汽车电池;在美国、欧盟和澳大利亚等地区，这一数字令人担忧，目前这些地区的典型回收率为5%。这些因素为采用家用电池储能系统（BESS）创造了强大的驱动力，该系统i）通过存储太阳能和低成本电力来减少企业和家庭的能源账单ii）支持电网提供额外的收入和系统节省iii）利用二手电动汽车电池和零/负成本。然而，现有的BESS的投资回收期约为7年，高资本支出约为5，000 - 7，000英镑，并且电池寿命/更换是关键的成本问题。Powervault调查了其历史上没有购买BESS的潜在客户：55%的人反对成本，还有24%的人反对终身投资回报。反过来，与有激励措施的国际市场（德国、日本、澳大利亚、美国）相比，联合王国的吸收率一直很低。为了满足这一需求，Powervault计划开发一种创新的大众市场BESS解决方案，使用二次电池（SLBESS），并利用关闭资源循环。该项目构成了技术和商业模式创新，提供了一个从第一天起就为客户带来现金流的系统，因为i）没有前期成本ii）延长了电池寿命和保修期iii）整合了电网服务以产生收入。这一创新解决了关键的竞争主题：脱碳能源，商业和工业。零前期成本的SLBESS解决方案为大众市场住宅能源灵活性提供了一条途径，这对于以最低成本脱碳至关重要（BEIS，Element Energy，Imperial College）。创新解决的其他主题是提高我们家庭和其他建筑物的能源效率（通过帮助家庭在更有效的时间进口电力，因为他们转向电热和运输），并加速向低碳运输的转变（通过减少电网限制和电动汽车制造商的回收成本，降低价格）。

The Government has committed to Net Zero GHG emissions by 2050, but is already off-track to meet its 2020 renewable electricity target(CCC), whereby households account for 40% of emissions. In tandem, households and businesses face increasing energy bills as we electrify transport and heat, with costs of £40bn by 2050 where unmitigated with flexible energy assets. Renewable energy(RE) is constrained by with an inflexible grid unable to handle variable supply, with costly new curtailment measures (£500m) introduced from over-supply during Covid-19\. Finally, figures from Birmingham University, IET and IEA calculate that there will be 30-60m tonnes of waste EV batteries globally by 2040; alarming in regions such as the US, EU and Australia where typical recycling rates are presently 5%. These factors create strong drivers for adoption of domestic Battery Energy Storage Systems (BESS) that i)reduce business and household energy bills by storing solar and low cost electricity ii)support the grid providing extra revenues and system savings iii)utilise second-hand EV batteries and no/negative cost. However, existing BESS have payback periods of ~7yrs, high CAPEX ~£5,000-£7,000, and with battery lifespan/replacement being a key cost concern. Powervault has surveyed its historic pipeline of leads who did not buy BESS: 55% objected on cost, and a further 24% on warrantied-lifetime payback. In turn, uptake in the UK has been low compared to international markets where incentives are available(Germany, Japan, Australia, USA). To meet this need Powervault plans to develop an innovative mass-market BESS solution using second-life EV batteries(SLBESS) and capitalise on closing a resource loop. This project constitutes technical and business model innovation, providing a system that is cashflow positive for customers from day 1 due to i)no upfront cost ii)improved battery lifespan and warranty duration iii)integration of grid services to generate revenue. This innovation addresses the key competition theme: decarbonising energy, business and industry. A zero upfront cost SLBESS solution provides a pathway to mass-market residential energy flexibility, which is critically needed for decarbonising at least cost (BEIS, Element Energy, Imperial College). Other themes the innovation addresses are improving the energy efficiency of our homes and other buildings (by helping homes import electricity at more efficient times as they switch to electric heat and transport) and accelerating the shift to low carbon transport (by reducing grid constraints and recycling costs for EV manufacturers, lowering price).
