Development of Global Hydrogen and Ammonia Zero-carbon Energy Systems

氢有望为全球经济脱碳做出重大贡献。“绿色”氢可以在澳大利亚、智利和中东等太阳能和风能潜力大的地区廉价生产，但由于其能量密度低，运输成本高昂。由绿色氢产生的氨运输成本更低，可用于运输、商业、住宅和工业部门，而不是氢，但其潜在的好处尚未得到研究。本研究项目的目的是严格评估在向全球净零排放过渡期间使用全球交易的氨和/或氢的长期案例。该研究将在BSEER中使用TIAM-UCL全球综合评估模型。学生将通过定义氢和氨的供应、储存、分配和最终用途，以及每种商品的贸易，来学习使用这个模型。他们将使用脱碳情景分析来确定这些能源载体的关键特征、利益和挑战。对于最具竞争力的氨用途，案例研究将考察技术、经济和监管障碍，这些障碍将阻碍市场增长，从而阻碍脱碳努力。该项目将补充BSEER的氢能研究计划。

Hydrogen is expected to make a substantial contribution to decarbonising the global economy. "Green" hydrogen can be produced cheaply in regions with high solar and wind potential such as Australia, Chile and the Middle East, but is expensive to transport due to its low energy density. Ammonia produced from green hydrogen would be cheaper to transport, and could be used in the transport, commercial, residential, and industry sectors instead of hydrogen, but the potential benefits have not been previously investigated. The objective of this research project is to critically assess the long-term case for using ammonia and/or hydrogen traded globally during the transition to global net zero emissions.The research will use the TIAM-UCL global integrated assessment model in BSEER. The student will learn to use this model through defining the supply, storage, distribution and end-uses of both hydrogen and ammonia, together with trade of each commodity. They will use decarbonisation scenario analyses to identify key characteristics, benefits, and challenges for these energy vectors. For the most competitive uses of ammonia, case studies will examine technological, economic and regulatory barriers that would impede market growth and hence decarbonisation efforts. This project will complement the hydrogen energy research programme in BSEER.
