The Japanese government has announced a commitment to net-zero greenhouse gas emissions by 2050. It envisages an important role for hydrogen in the nation's future energy economy. This paper explores the possibility that a significant source for this hydrogen could be produced by electrolysis fueled by power generated from offshore wind in China. Hydrogen could be delivered to Japan either as liquid, or bound to a chemical carrier such as toluene, or as a component of ammonia. The paper presents an analysis of factors determining the ultimate cost for this hydrogen, including expenses for production, storage, conversion, transport, and treatment at the destination. It concludes that the Chinese source could be delivered at a volume and cost consistent with Japan's idealized future projections.
日本政府已宣布致力于到2050年实现温室气体净零排放。它设想氢在该国未来能源经济中将发挥重要作用。本文探讨了这样一种可能性，即这种氢的一个重要来源可以由中国海上风电产生的电力驱动电解来生产。氢可以以液体形式、与化学载体（如甲苯）结合或作为氨的成分输送到日本。本文对决定这种氢最终成本的因素进行了分析，包括生产、储存、转化、运输和在目的地处理的费用。结论是，来自中国的氢源可以以与日本理想化未来预测相一致的数量和成本进行输送。
