Japanese utility Jera plans to demonstrate the potential of hydrogen co-fired technology at existing combined-cycle gas-turbine (CCGT) units in New York

Just 5% replacement by hydrogen as CCGTPP fuel in 2030! 

Does this worth all propaganda about hydrogen in energy central ?

Engineering sense says it is an illusion .

Not all shining is gold.

Worse than that, Dr. Amal: if 5% of natural gas is substituted with hydrogen made by steam-reforming natural gas ("gray" hydrogen), and the energy efficiency of steam reforming gas is only 70%, the substitution will reduce the overall efficiency of the process by 1.5% (increasing emissions by 1.5%).

The more gray hydrogen that is added, the less efficient the process will be. Burning 100% gray hydrogen to generate electricity would be 30% less efficient than simply burning the natural gas used to make it instead, and will result in a 30% increase in CO2 emissions. Why would any utility want to waste natural gas to produce its electricity? Because it can all be billed to ratepayers, and ratepayers who are under the delusion their utility is burning clean hydrogen will gladly pay it.

It is gold, alright - gold transferred from your pockets to those of your utility's stockholders, for nothing of value in return.
