I agree,
which is why my link did not suggest 'bio-methanol'.
I believe the operators of large vessels will switch to methanol,
to reduce the NOx & SOx emissions from standard, (high Sulphur fuel oils).
Some are ordering new build vessels with twin fuel capability.
Potentially they are waiting for someone to devise a method of making bio-methanol from a waste stream, (say bio-digested post consumer food waste).
You can make methane (natural gas) from co2 and hydrogen. Doing so on an industrial scale is a (much) bigger challenge. I think spacex are looking at it, as a way of generating fuel (on mars and earth) for their rockets.
