What is your preferred form of Hydrogen? Gaseous or Liquid Hydrogen?

[Björn Lüssow]

Indeed, I think it relates to the use case plus the development and the systems on liquid hydrogen are only in the making.

[Brad Reams]

Bjorn, I agree. It will be easier and cheaper to move the hydrogen as a gas. Although, there are starting to be some positive results of boil off tests which will make the refueling transportation much easier.

My preferred form of Hydrogen is “Available”

[Ganapathy Iyer]

A choice between Liquid Hydrogen and Gaseous Hydrogen is more of an infrastructure based choice than a OEM’s choice

I don’t think that majority of the world is ready for Liquid Hydrogen

[Brad Reams]

Ganapathy,

I agree with you, gaseous is much more ready to be utilized than liquid hydrogen. When there is a push for liquid hydrogen to be more available, the cost of liquifaction will reduce through new technological advances and efficiencies just as we have seen with other green technologies.

I´d extend the question by “chemical stored in feedstock” !?

I´ve learned that depends on the given application and infrastructure.

Mobile applications land based: cars and trucks gasified hydrogen on different pressure levels
Infrastructure is a grid and gas stations

Mobile applications non land based: vessels chemical stored in liquid feedstock ammonia or methanol
Infrastructure is a buffer tank system combined with a reformer

Stationary applications: gasified hydrogen for FC CHP systems
Infrastructure is a pipeline grid

Large scale hydrogen production and transport – disconnected from consumer application: liquified hydrogen e.g. wind power plants and solar power plants

Liquid Hydrogen. Low Pressure, High Purity, Compact
