摘要:

氢能是实现能源安全和“双碳”目标的重要途径,是全球新能源发展的重要方向之一。我国西部地区可再生能源丰富,绿氢制备潜力大,但能源消费主要集中在东部地区,供需错配问题突出,研究开展“西氢东送”能有效缓解我国资源错配问题,促进我国氢能产业高质量发展。本文阐述了实施“西氢东送”的必要性,介绍了气态、液态、化学储氢介质、固态及有机液体储运技术路径,从技术特点、技术成熟度、标准体系和市场应用4个方面进行了技术可行性分析比较,提出以化学储氢介质、液氢、管道输氢为近期、中期、远期实现“西氢东送”可行的技术路径。再进一步以甘肃省酒泉市运输至上海市为实例,分别以绿氨、绿色甲醇、液氢和管道输氢为“西氢东送”实现路径,构建包括制氢、介质、运输、还原和配送各环节的供应链模型,通过测算供应链全过程综合成本,分析比较了经济可行性。综合研究表明,近期通过成熟的绿氨及绿色甲醇作为储运介质、中期逐步发展液氢运输方式、远期建设大规模长距离输氢管道,是我国实现“西氢东送”的可行路径。

Abstract:

Hydrogen energy is crucial for achieving energy security and dual carbon goals, representing important directions of global new energy development. China's western region is rich in renewable energy sources, and green hydrogen production potential is large, but the energy consumption is mainly concentrated in the eastern region, resulting in a noticeable supply and demand mismatch. Research and development of "West-to-East hydrogen transmission" can effectively alleviate this resource mismatch in China and promote the development of a high-quality hydrogen industry. This study expounds on the necessity of implementing "West-to-East hydrogen transmission" and introduces various storage and transportation technology paths encompassing gaseous, liquid, chemical hydrogen storage medium, and solid and organic liquid. Comprehensive technical feasibility analysis and comparison are conducted across four aspects: technical characteristics, technical maturity, standard system, and market application. The proposed feasible technical paths to realize "West-to-East hydrogen transport" in the near, middle, and long term include chemical hydrogen storage mediums, liquid hydrogen, and pipeline hydrogen transport. Taking the transportation route from Jiuquan City in Gansu Province to Shanghai as an example, a supply chain model is constructed, including hydrogen production, medium storage, transportation, reduction, and distribution. Economic feasibility was analyzed and compared by calculating the comprehensive cost of the whole supply chain process. The comprehensive study shows that mature ammonia and methanol as storage and transportation media, respectively, are feasible in the near term. In the medium term, the development of a liquid hydrogen transport mode is advisable, while in the long term, constructing large-scale, long-distance hydrogen transport pipelines emerges as a viable strategy for realizing "West-to-East hydrogen transport" in China.

Key words: hydrogen energy, west-to-east hydrogen transmission, technical feasibility, economic feasibility
