Analysis of Future Application Scenarios of Methylcyclohexane-Toluene Hydrogen Storage Technology
Methylcyclohexane to toluene is one of the most promising organic hydrogen storage technologies,which is expected to be an effective solution to the problem of hydrogen storage and transportation.The paper analyzes such five possible application scenarios of methylcyclohexane to toluene hydrogen storage in the future as international hydrogen supply chain and hydrogen trade,transmission of hydrogen from the west to the east,large-scale offshore hydrogen storage and transportation for hydrogen production by offshore wind power,the large-scale hydrogen storage of renewable energy,and small-scale skid-mounted distributed hydrogen storage and supply.In the scenario of international hydrogen supply chain,it can make full use of the existing oil infrastructure,oil carriers,loading and unloading terminals,storage tanks,pipelines,and tank cars to reduce investment and hydrogen costs.In the scenario of transporting hydrogen from the west to the east,a new channel for large-scale transportation of renewable energy in the Three-North Region to the southeast coastal consumer market would be constructed through oil pipelines.In the scene of large-scale offshore hydrogen storage and transportation for hydrogen production by offshore wind power,the off-grid hydrogen production and large-scale offshore hydrogen storage and transportation of offshore wind power base are explored to realize non-electric storage and transportation and consumption of offshore energy in the deep sea with the help of existing offshore oil and gas facilities.In the large-scale hydrogen storage of renewable energy,a new hydrogen storage mode of hydrogen production-storage-consumption integration is formed by taking advantage of the conventional low-cost storage of organic hydrogen at normal temperature and pressure.In the small skid-mounted distributed hydrogen storage and supply scenario,a small skid-mounted hydrogen storage and dehydrogenation device is used to store hydrogen flexibly close to the hydrogen source and dehydrogenate conveniently close to the user,and to construct a new format of integrating and utilizing the existing oil infrastructures.
