The map above shows oil and gas fields of North America. Alberta has significant natural gas reserves and production capability.
As States shift to renewable (i.e. green) electricity generation from intermittent sources such as wind, solar, and hydro, there would be significant need for energy storage or controllable electricity generation from natural gas or Hydrogen.
In contrast to crude oil, Alberta produces natural gas with lower carbon emission than worldwide average. Alberta is also well positioned to be lowest cost blue Hydrogen producer. Blue hydrogen is produced by reforming natural gas, and separating, capturing, and sequestering (i.e. storing) carbon.
A pipeline can transport blue hydrogen from Alberta to the States. This would provide energy security and reliability, and enable an orderly and faster transition from energy systems of today to completely green energy systems of the near future.
The question then is, can Keystone XL be repurposed to transport Hydrogen from Alberta to the States?
And if it can be, would President of United States (and others) find it in public interest?
