DEcarbonisation of Low TemperAture Process Heat Industry, DELTA PHI

2018年提供的低温工业过程热占英国工业一次能源使用总量的30%以上。其中75%是通过燃烧石油、天然气和煤炭生产的。低温过程热是许多工业部门能源使用的主要组成部分，包括食品和饮料，化学品和药品，金属产品和机械制造，印刷和纺织。为了减少与低温制热相关的温室气体排放，并实现英国的目标，从长远来看，将需要向零碳电力、燃料或可再生热能过渡。在短期内，这是不可行的。我们提出一种方法，在工业过程中更有效地利用热量，和/或出口以满足邻近地区的热量需求，从而大大减少单位工业生产的温室气体排放，并可能提供额外的收入来源。我们将执行一项研究计划，帮助提供一条无悔的路线，通过过渡到最终的全面脱碳。该研究包括：1)基础研究和应用研究，以经济有效地改进组件和系统性能，以改进热回收、热储存、热升级、高温热泵和低损耗传热；ii)开发新的时间建模方法，以预测如何将这些技术有效地集成在多矢量能源系统中利用热量，并评估交互式建模平台，以解决如何在能源系统中经济地利用热量的复杂性。一系列的案例研究将分析潜在的温室气体减排和可能实现的成本效益和收入，包括赫尔的一个化学生产设施，以评估i)单个技术的效益，ii)在加热/冷却网络中的最佳集成，或iii)在多矢量能源系统中的组合。

The provision of low temperature industrial process heat in 2018 was responsible for over 30% of total industrial primary energy use in the UK. The majority of this, 75%, was produced by burning oil, gas and coal. Low temperature process heat is a major component of energy use in many industrial sectors including food and drink, chemicals and pharmaceuticals, manufacture of metal products and machinery, printing, and textiles. To reduce greenhouse gas emissions associated with low temperature process heat generation and meet UK targets, in the long term, will require a transition to zero carbon electricity, fuels or renewable heat. In the short term this is not feasible. We propose an approach in which heat is more effectively used within the industrial process, and/or exported to meet heat demands in the neighbouring area allowing significant reductions in greenhouse gas emissions per unit industrial production to be achieved and potentially provide an additional revenue source.We are going to perform a programme of research that will help provide a no regrets route through the transition to eventual full decarbonisation. The research consists of, i) fundamental and applied research to cost effectively improve components and systems performance for improved heat recovery, heat storage, heat upgrading, high temperature heat pumping and transporting heat with low loss, and ii) develop new temporal modelling approaches to predict how these technologies can be effectively integrated to utilise heat across a multi-vector energy system and evaluate a transactive modelling platform to address the complexity of how heat can be reutilised economically within energy systems.A series of case studies analysing the potential greenhouse gas reductions and cost benefits and revenues that may be achieved will be undertaken for selected industrial processes including a chemical production facility in Hull, to assess the benefits of i) individual technologies, ii) when optimally integrated within a heating/cooling network, or iii) when combined in a multi-vector energy system.
