大规模储能提供了在低碳能源系统中捕获和使用多余电力的前景，否则这些电力可能会被浪费。将存储的作用扩展到当前的场景工具中具有挑战性，因为它需要高时间分辨率来反映间歇性源对系统平衡的影响。本研究利用了具有这种分辨率的模型的结果。它的结论是，大规模的存储可以成为经济上可行的方案与高渗透率的可再生能源。随着间歇性能源比例的增加，最佳的存储类型转向具有低能源相关成本的解决方案，即使以效率为代价。然而，已经确定了一系列的不确定性，涉及存储技术的发展，监管环境，存储的替代品和同比收入的随机不确定性。所有这些都对融资成本和成功进入市场的机会产生了负面影响。因此，我们认为，如果要实现存储的存在可能带来的更广泛的系统和社会效益，可能需要更强有力和更具战略性的政策支持。需要就储存的社会和系统效益开展更多工作，以衡量支持措施的适当程度。
Large scale storage offers the prospect of capturing and using excess electricity within a low carbon energy system, which otherwise might have to be wasted. Incorporating the role of storage into current scenario tools is challenging, because it requires high temporal resolution to reflect the effects of intermittent sources on system balancing. This study draws on results from a model with such resolution. It concludes that large scale storage could become economically viable for scenarios with high penetration of renewables. As the proportion of intermittent sources increases, the optimal type of storage shifts towards solutions with low energy related costs, even at the expense of efficiency. However, a range of uncertainties have been identified, concerning storage technology development, the regulatory environment, alternatives to storage and the stochastic uncertainty of year-on-year revenues. All of these negatively affect the cost of finance and the chances of successful market uptake. We argue, therefore, that, if the possible wider system and social benefits from the presence of storage are to be achieved, stronger and more strategic policy support may be necessary. More work on the social and system benefits of storage is needed to gauge the appropriate extent of support measures.
