摘要

According to oilprice.com, hydrogen production via steam methane reforming has a larger carbon footprint compared to NG-based hydrogen production. While carbon capture & storage can also be used in conjunction with fossil fuel-based hydrogen production, this route is rather uneconomical. While electrolysis has shown potential as low-carbon hydrogen production route, the process will require either renewable energy or nuclear power in order to be considered low-carbon. On the other hand, use of excess intermittent power or cheap, low-carbon electricity will substantially reduce the carbon footprint of hydrogen production, with some estimates projecting an 80-90% lower environmental impact compared to steam methane reforming for some processes.
