Hydrogen Transportation 2021

Nvember 12, 2021

Hydrogen has high energy per weight, however, has low density therefore; low energy per volume.

Having low boiling point (-253 degrees C) and low-density results in challenges in storage and transportation.

Can be shipped as pure Hydrogen or utilizing a Hydrogen carrier, via ammonia (NH3) and Methylcyclohexane (MCH).

Pipeline Blending

Hydrogen blending into natural gas pipelines is considered an option to grow hydrogen capability without the large upfront costs and time of developing a dedicated hydrogen pipeline network.
Hydrogen as a renewable gas, with associated credits, could be important in utilising the North American natural gas pipeline grid.
SMR in combination with CCS could utilise the North American pipeline grid to provide low/no carbon option.
Economic incentive for converting excess curtailed energy from renewable sources (wind, solar) into hydrogen.
Safety is the most important factor for operators of natural gas pipelines throughout North America.
2013 NREL study* concluded low concentrations (<5-15% hydrogen by volume) of hydrogen blending in Natural gas pipelines was viable.
Enbridge Gas received permission from the Ontario Energy Board to blend up to 2% hydrogen** from Electrolysis in Markham, Ontario.
Hydrogen is lower density than natural gas therefore, requires 30% more pipeline space to delivery the same energy (Btu basis).
