项目摘要

As part of its effort to commit essentially net zero carbon emissions by 2050, the UK Government announced a new plan in March 2019 to ban gas boilers in new houses after 2025. This is based on a fact that residential buildings accounted for about 25% of total UK greenhouse gas emissions in 2012, of which 55% were directly from gas, according to the Committee on Climate Change. The Committee advised direct emission reductions of 36% by 2025 and 53% by 2030 from 2007 levels in buildings. This has led to an imminent demand for replacement low or zero carbon heating technologies.Solar thermal technology appears a primary option to meet this demand, but possesses a common drawback, that is the temporal mismatch between solar heat production and heating demand in buildings. Seasonal storage of solar heat is an essential way to address the mismatch between heating demand in winter and solar heat production in summer. Of the three main technologies available, energy density of thermochemical energy storage is superior to conventional sensible and latent heat storage by several-fold factor and has a further advantage of negligible storage heat loss.The proposed project is aimed to investigate a new solar driven thermochemical energy storage system using several innovative designs such as closed air loop, pressure control, embedded internal heating/cooling, hollow polymer fibre heat exchanger, and integrated dehumidification/evaporative cooling. The proposed system has been devised to address several drawbacks experienced by typical thermochemical energy storage systems and will also use low temperature solar heat to enhance the heat release discharging process by humidifying air flow at a slightly higher temperature. The project is built on our recent research on the design and fabrication of composite salt-in-matrix as thermochemical energy storage materials.Development of the proposed system has the potential of reducing fossil energy usage in space heating and hot water. Implementation of such technology would allow the UK to greatly increase its utilisation of solar energy and achieve the target of decarbonisation in heating. This project will demonstrate to domestic consumers, house builders, industry and local authorities the practicality of heating buildings by renewable energy without increasing costs. The project will also provide an opportunity for UK industries to pioneer the development of a new advanced solar heat storage technology.

为了在2050年到2050年实施实质性净碳排放量的努力的一部分，英国政府于2019年3月宣布了一项新计划，以在2025年后禁止在新房屋中禁止燃气锅炉。这是基于这样一个事实，该事实是，根据气候变化，该委员会在2012年的UK Greenhouse Greenhous Gas Ensions占2012年UK Greenhouse总量的25％。该委员会建议到2025年直接减少36％，到2030年，从2007年的建筑物降低了53％。这导致了对替换较低或零碳加热技术的迫在眉睫的需求。SolarThermal Technology似乎是满足这一需求的主要选择，但具有共同的缺点，这是太阳能热量生产与建筑物中的加热需求之间的时间不匹配。太阳热量的季节性存储是解决冬季加热需求与夏季太阳能产量产生之间不匹配的一种重要方法。在可用的三种主要技术中，热化学能量存储的能量密度优于传统的明智和潜在的热量储存，并通过多个因素储存，并具有可忽略不计的储存热量的进一步优势。拟议的项目旨在研究一种新的太阳能驱动的热化学能源存储系统除湿/蒸发冷却。该系统已设计为解决典型的热化学能量储能系统所经历的几个缺点，还将使用低温太阳热来通过在稍高的温度下加湿空气流量来增强释放热量排放过程。该项目建立在我们最近的关于矩阵中复合盐的设计和制造作为热化学能量储能材料的研究基础上。拟议系统的开发具有减少空间加热和热水中的化石能量的潜力。这种技术的实施将使英国能够大大提高其对太阳能的利用，并实现脱碳化的目标。该项目将向国内消费者，房屋建筑商，工业和地方当局证明通过可再生能源供暖建筑物的实用性，而不会增加成本。该项目还将为英国行业提供一个机会，以开发新的先进太阳能储热技术。
