Shell Process To Make Blue Hydrogen Production Affordable

The title of this post, is the same as that of this article on Trade Arabia.

This is the introductory paragraph.

Shell Catalysts and 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, utilisation and storage (CCUS).

Note.

  1. Grey hydrogen is generally defined as hydrogen produced from natural gas, by a process like steam-reforming.
  2. Blue hydrogen is generally defined as hydrogen produced from natural gas, where the carbon is captured and stored, instead of being released into the atmosphere.
  3. Green hydrogen is hydrogen produced by electrolysis using renewable energy.
  4. Shell are claiming, that with carbon dioxide costing $25-35/tonne, that their process is more economic than grey or green hydrogen.
  5. Steam reforming also needs steam, but this new process actually generates steam as a by-product, which further improves the economics, as integrated chemical plants use a lot of steam.
  6. Shell are reporting capturing 99% of the carbon.
  7. It looks like savings of between 10 and 25 % are possible.

Shell have made a big technological breakthrough, as it will allow natural gas to be converted direct to hydrogen without contributing to global warming.
