The project will utilise a range of energy systems models developed by the Energy Systems Catapult to investigate the flexibility of energy systems at a national or regional scale. The research will focus on the amount of flexibility needed under a range of different future scenarios and a comparison of different options; in particular the research will consider the future role of gas networks in facilitating decarbonisation, and the use of thermal storage. The project sits within the School of Chemical Engineering, the Birmingham Centre for Energy Storage and the Birmingham Energy Institute.A backbone of Britain's current energy systems is the natural gas network that provides much of Britain's non-transport energy demands, especially over the winter period when space heating demands are at their highest. Significant progress has been made in decarbonising the power sector (in 2018 Great Britain generated around 20% of its electrical generation from wind and solar sources) leading to the lowest per kWh power sector emissions.The provision of heat is arguably the next greatest challenge for Britain, due to a number of energy system factors including the prevalence of the existing natural gas network (80%+ of homes connected to the gas grid), the seasonality of the demand (it is colder in the winter than the summer) and the within day swings of demand for natural gas. These engineering challenges are driven by consumers, who have a high level of expectation from their heating systems, and a familiarity with the current system. The natural gas system has inherent flexibility over a number of different timeframes such as the seasonal flexibility helped by international supply chains that provide greater amounts of natural gas in the winter than the summer. Linepack is the amount of gas contained in the natural gas networks, and this can be increased or decreased by changing the pressure in the higher-pressure parts of the gas network. This is used to balance significant demand swings within a day. The gas system provides the greatest amount of within day flexibility to Britain's energy systems - and this research will help to build knowledge of the levels and types of flexibility that future energy systems in Britain might require.

该项目将利用能源系统弹射器开发的一系列能源系统模型来研究国家或地区范围内能源系统的灵活性。研究将重点关注未来一系列不同情景下所需的灵活性以及不同选项的比较；该研究将特别考虑天然气网络在促进脱碳和热储存的使用方面的未来作用。该项目位于化学工程学院、伯明翰储能中心和伯明翰能源研究所内。英国当前能源系统的支柱是天然气网络，它满足了英国的大部分非运输能源需求，特别是在冬季当空间供暖需求最高时。电力行业脱碳取得了重大进展（2018 年，英国约 20% 的发电量来自风能和太阳能），电力行业每千瓦时排放量降至最低。 供热可以说是下一个最大的挑战英国，由于许多能源系统因素，包括现有天然气网络的普及（80%以上的家庭连接到燃气网）、需求的季节性（冬天比夏天冷）以及天然气需求的日内波动。这些工程挑战是由消费者驱动的，他们对供暖系统抱有很高的期望，并且熟悉当前的系统。天然气系统在许多不同的时间范围内具有固有的灵活性，例如国际供应链在冬季提供比夏季更多的天然气所带来的季节性灵活性。管线包是天然气网络中所含的气体量，可以通过改变天然气网络高压部分的压力来增加或减少。这用于平衡一天内的显着需求波动。天然气系统为英国能源系统提供了最大程度的日内灵活性，这项研究将有助于了解英国未来能源系统可能需要的灵活性水平和类型。
