By 2035, additional 1.6 billion people will require energy, as global population hits 8.7 Billion. The finite fossil fuel resources with considerable Greenhouse Gas (GHG) impact would require a cleaner, sustainable and long-tern alternatives. Avoidance projects ( solar / wind) alone cannot solve the problem, Hydrogen energy offers one such alternative.

  1. Existing Markets: Long-term strategy in existing hydrogen markets requires converting Grey hydrogen produced using fossil fuel (methane) to Blue hydrogen using CCS (leveraging existing infrastructure)
  2. New Hydrogen Markets : Long-term requires commercialization of Green Hydrogen (developing new infrastructure)
  3. Underground H2 Storage Option
  • Physical storage options like surface storage in high-pressure vessel are ver expensive and small scale.
  • Material Storage options in surface are attractive for transportation but currently in research realm.
  1. Underground Hydrogen Storage (UHS) is a key enabling technology for the advancement of hydrogen and fuel cell technologies in applications including stationary power, portable power, and transportation.

Moving from stand-alone project to regional hub will reduce cost and  risk .  Three capabilities are required to have competitive advantage

  1. Site Characterization  - Data  Driven 
  2. Venture Shaping - Business Driven (Most challenging)
  3. Project and Asset Development ( Project Management & Engineering Driven)

Underground Storage Options

  1. Salt Caverns - Currently most commonly used.
  2. Depleted Oil & Gas (DOG) Fields
  3. Saline Aquifer


A Regional Hydrogen Hub (RHH), plays a pivotal role in harnessing economies of scale. An industrial hub/port with, several refineries and chemical plant in proximity, along with network of natural gas, CO2 and Hydrogen pipelines, with several salt caverns and CCS sinks in proximity and existing infrastructure can all help bring down the cost.  UK’s Teeside is a good example and Houston shipping channel meets the description for Houston Hydrogen Hub.

Kudos for recognizing that blue hydrogen must precede green hydrogen. Truly green hydrogen can only be produced from a fully decarbonized energy grid. Otherwise there is competition for use of green energy on the grid. Any green energy that is used to produce hydrogen forces other applications to use dispatchable fossil energy.

One minor quibble: you state that grey hydrogen can be converted to blue by appending a CCS step. In practice, that's not the way you'd want to do it. It's more cost-effective to implement a process that is designed from the outset for carbon capture. There are several candidates that have been rigorously simulated and tested.

Another point is that the options you list for hydrogen storage omits what, IMO, may actually be the most cost effective. That's to build a relatively large-diameter (e.g., two meters) hydrogen pipeline. Such a pipeline can be more efficient for transporting bulk energy over long distances than a high voltage transmission line. If the pipeline is a few hundred miles long, the volume of pressurized hydrogen it holds is immense. There will be hydrogen producers and consumers distribute all along the length of the pipeline.
