Proposed first project needs support of magnitude of costs of an offshore wind wheel plus research efforts, what may multiply costs by factor 2 as a thumb bearing.

Offshore wind wheel placement requires national states support.

Research efforts may not be possible only by private investments.

Green methane production via green hydrogen generation is still a not totally cleared and well running process.

Operation of the plant may stay a private business.

Transfer of products needs surely national states licensing.

Sponsoring will be a complex business itself.

Sponsors realize financial support.
