A step in the right direction. Green methanol is not widely available but once produced can be swapped for other methanol giving global availability mostly from natural gas until capacity is in place near ports. When made from green hydrogen can be produced whereever you can collect carbon dioxide.
A cost premium for the e-methanol is expected but no estimates provided. Methanol is nearly 50% oxygen implying about twice as much required for equivalent energy content as diesel fuel.
Maresk will get its green methanol from China.
They are saying green methanol is the best choice for green diesel fuel. LNG is suggested as better than diesel but still high in carbon. Green methanol recycles carbon dioxide. Ammonia sometimes mentioned but methanol seems to be preferred. Possibly methanol is suitable for distribution in existing diesel fuel tanks and pipelines. Flammable liquid. Requires explosion proof equipment. And toxic but not usually a concern unless swallowed in quantity.
