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.
