It’s in the Far East, however, where a certain hydrogen like ammonia, might become “standard”. The Keppel deal includes an “aside” MOU with

Mitsubishi Heavy Industries for “a feasibility study on the development of a 100-percent ammonia-fuelled power plant on a selected site in Singapore”.

That’s 3-for-1: gas-?ring at the same plant gives way to H2 ei- ther from water or natural gas, which is then converted to am- monia. Energy trilemma solved.

“When completed, this asset will grow Keppel’s power gen- eration portfolio from the cur- rent 1,300 MW to 1,900 MW,”
