Storage and Transportation Technology Solutions Selection for Large-scale Hydrogen Energy Utilization Scenarios under the Trend of Carbon Neutralization

This paper mainly introduces the main pain point of China's civil hydrogen energy supply chain - the problem of storage and transportation, and analyzes the safety, economy and scale effect and other issues of the existing hydrogen energy storage and transportation, compares with other storage and transportation technology solutions, and comprehensively screens out the storage and transportation technology solution mainly based on liquid hydrogen technology. The liquid hydrogen technology solution has significant advantages over the existing compressed hydrogen system in terms of safety, economy and scale effect, especially for future large-scale hydrogen energy application scenarios. In addition, the future hydrogen energy storage and transportation system based on liquid hydrogen technology can help improve the overall utilization efficiency of country’s renewable energy, promote the country's energy transition, promote the electrification of the country's transportation sector, and help achieve China's carbon emission reduction 2030/2060 target.
