据天然气工业11月2日消息称，壳牌催化剂技术公司（Shell Catalysts＆Technologies）推出了壳牌蓝氢工艺，该工艺集成了成熟的技术，可以显著提高从天然气中生产“蓝”氢以及碳捕获、利用和存储(CCUS)的新项目的可承受性。价格低廉的蓝氢能使难以减排的重工业脱碳，同时为炼油厂和资源所有者创造价值。与目前市场上最好的工艺相比，壳牌公司的新工艺可以降低22%的平准化氢成本。
没有低碳氢，政府和企业宣布的净零目标将难以实现。当前，氢气的生产几乎全部是“灰色”的（来自没有CCUS的碳氢化合物）。如果要实现碳中和，氢的生产规模必须大得多，排放水平也要低得多。
蓝色氢的生产可以相对容易地扩大规模以满足需求。二氧化碳的价格为每吨25-35美元，因此，尽管资金成本更高，蓝色氢仍能与灰色氢竞争。到2030年，可再生能源电解水生产的绿色氢的价格仍可能是蓝色氢的两倍多，而成本要到2045年左右才能达到同等水平。

Shell Catalysts & Technologies launches the Shell Blue Hydrogen Process
Shell Catalysts & Technologies is launching the Shell Blue Hydrogen Process, which integrates proven technologies to increase significantly the affordability of greenfield projects for “blue” hydrogen production from natural gas along with carbon capture, utilization and storage (CCUS). Affordable blue hydrogen enables the decarbonization of hard-to-abate heavy industries while creating value for refiners and resource holders. Shell’s new process can reduce the levelized cost of hydrogen by 22% compared with the best the market has to offer today.
Without low-carbon hydrogen, the net-zero goals announced by governments and companies will be difficult to achieve. Currently, hydrogen production is nearly all “grey” (from hydrocarbons without CCUS). If hydrogen is to contribute to carbon neutrality, it must be produced on a much larger scale and with far lower emission levels.
Blue hydrogen production can be relatively easily scaled up to meet demand. With carbon dioxide (CO2) costing $25–35/t, blue hydrogen becomes competitive against grey, even with its higher capital costs. And green hydrogen, produced from the renewable-energy powered electrolysis of water, may still be more than double the price of blue hydrogen by 2030 and not achieve cost parity until about 2045.
