an increasing number of European clean energy projects are looking at the production of green hydrogen and pow- er-to-X fuels such as ammonia on ?oating platforms.

In a study of the North and Baltic Seas, DNV concluded that the lower costs of hydrogen transmission compared to electricity and the possibility for large pipelines to ag- gregate offshore hydrogen production from several wind- farms, makes offshore hydrogen production an attractive option for offshore wind farms, certainly at distances of more than 100 kilometers from shore.

The alternative is shipping molecules to shore, and Ma- ciek Lukawski, VP of Strategy & Business Development for ammonia power solutions company Amogy, points out that, for locations like Japan, Europe and the US with lim- ited shallow waters and strong interest in ammonia, ?oating production platforms will enable strategic access to clean ammonia. “Transportation of green ammonia through shipping can provide widespread access in the near future rather than the development of offshore pipelines.” Amo- gy has signed MoUs with Southwind to promote offshore wind development and Marco Polo Marine to develop its ammonia-to-power solution for deployment on OSVs.

Shipping will still involve new piping solutions. Earlier this year, H2Carrier and Trelleborg Gas Transfer signed an

MoU on ship-to-ship ammonia transfer systems that will be based on Trelleborg’s KLAW LNG technology and up- graded to operate with liquid ammonia.

H2Carrier has developed the P2XFloater for ?oating production of green hydrogen and ammonia. The con- cept is based on oil and gas technology combined with
