Significant growth in the capacity of variable wind and solar generation technologies and inflexible nuclear power stations in UK is crucial to achieving a net-zero electricity system by 2035 and a net-negative electricity system by 2050. Decarbonising the transport sector and a greater reliance on electricity for heating are expected to increase electricity peak demand further. The growing use of variable renewable energy sources for power generation poses several challenges to the operation of power systems, in particular, supply and demand imbalances. Currently, the GB power system relies on significant input from gas-fired and hydro-electric power stations for balancing peak demand. Further, 13 GW of new electricity storage is required by 2030 to balance the 34 - 77 GW of new wind and solar generation. Existing technologies for grid-scale energy storage have their own pros and cons in terms of cost, life cycle environmental impacts, and scalability. Tidal Range Schemes (TRSs) are renewable generation technologies that can also be operated as grid-scale energy storage facilities. This is a unique feature of TRSs which has not been investigated significantly and is the key focus of this project. TRSs, such as tidal lagoons and barrages, generate renewable electricity by creating an artificial head difference between water levels on the seaside, driven by tides, and water levels inside the basin, controlled by flow through the structure. TRSs have a significant advantage over many other forms of renewable energy generation in that they are based on a highly predictable resource. Electricity generation has been traditionally considered as the primary goal of TRSs and they are mainly designed to maximise electricity generation. However, such schemes - particularly with pumping - can be highly controllable and therefore can be used as energy storage facilities. There are a number of tidal range schemes at different sizes proposed in UK coastal waters, with several other sites being investigated. One of the barriers to TRS development is their relatively high capital cost (but typically connected to a long capital cycle). This leads to a high expected cost of electricity generation. However, operating TRSs as energy storage facilities enables them to increase their revenue through price arbitrage and providing ancillary and reserve services. This consequently makes the TRS business model more financially viable while supporting the operation of the electricity system. The capability of TRSs to function as grid-scale energy storage facilities can be enhanced by new approaches to design and operate TRSs. It is also crucial to consider techno-economic and life cycle environmental impacts of TRSs being utilised as storage facilities compared to other grid-scale storage technologies.In this proposed project, we will investigate the optimal design and operation of TRSs as configurable grid-scale energy storage. This also includes an economic assessment of the revenue of TRSs when they are utilised as energy storage, and techno-economic and comparative life cycle assessment of TRSs and other common storage technologies in order to provide a better understanding of the potential impacts of TRSs. The proposed project is formed of 6 work packages which are closely connected. The project team will be working with an Advisory Board to ensure that project will respond to the key challenges related to the utilisation of TRSs as grid-scale energy storage facilities as highlighted in the proposal and benefit a wide range of stakeholders.

英国可变风能和太阳能发电技术以及不灵活核电站容量的显着增长对于到 2035 年实现净零电力系统和到 2050 年实现净负电力系统至关重要。供暖用电预计将进一步增加用电高峰需求。越来越多地使用可变的可再生能源来发电，给电力系统的运行带来了一些挑战，特别是供需失衡。目前，英国电力系统依赖燃气和水力发电站的大量投入来平衡高峰需求。此外，到 2030 年，需要 13 吉瓦的新增电力存储来平衡 34 - 77 吉瓦的新增风能和太阳能发电。现有的电网规模储能技术在成本、生命周期环境影响和可扩展性方面各有优缺点。潮差方案（TRS）是可再生发电技术，也可以作为电网规模的储能设施运行。这是 TRS 的一个独特特征，尚未得到大量研究，也是本项目的重点。 TRS，如潮汐泻湖和拦河坝，通过在潮汐驱动的海边水位和流经结构的水流控制的盆地内水位之间产生人工水头差来产生可再生电力。与许多其他形式的可再生能源发电相比，TRS 具有显着优势，因为它们基于高度可预测的资源。传统上，发电被认为是 TRS 的主要目标，它们的主要目的是最大限度地提高发电量。然而，此类方案——尤其是抽水——可以高度可控，因此可以用作储能设施。英国沿海水域提出了许多不同规模的潮差方案，其他几个地点正在接受调查。 TRS 开发的障碍之一是其相对较高的资本成本（但通常与较长的资本周期有关）。这导致发电的预期成本很高。然而，将TRS作为储能设施运营使他们能够通过价格套利以及提供辅助和储备服务来增加收入。因此，这使得 TRS 商业模式在支持电力系统运营的同时在财务上更加可行。 TRS 作为电网规模储能设施的能力可以通过设计和操作 TRS 的新方法得到增强。与其他电网规模存储技术相比，考虑用作存储设施的 TRS 的技术经济和生命周期环境影响也至关重要。在这个拟议项目中，我们将研究 TRS 作为可配置电网规模的优化设计和运行能量储存。这还包括对 TRS 用作储能时的收入进行经济评估，以及对 TRS 和其他常见存储技术进行技术经济和比较生命周期评估，以便更好地了解 TRS 的潜在影响。拟建项目由6个紧密相连的工作包组成。项目团队将与咨询委员会合作，确保项目能够应对提案中强调的与利用 TRS 作为电网规模储能设施相关的关键挑战，并使广泛的利益相关者受益。
