How will the Hydrogen be transported from the site of creation to the power plant where it is used? Are you only considering co-location, or is it feasible to transport hydrogen to other locations (even internationally) as a proxy for the transport of coal.
The hydrogen production facility is co-located with the power plant to maximize the efficiencies between the operations. Hydrogen pipelines a re relatively common in the U.S. and Europe, but they are primarily involved in the transportation of hydrogen over shorter distances and not cross-country
