Sanlorenzo hopes to open ‘new chapter’ in hydrogen yachts


Sanlorenzo’s plan to build a hydrogen-fuelled superyacht in partnership with Siemens Energy, could open “a new chapter in terms of carbon neutral electricity sources for medium-size superyachts”.

It is a statement of intent from the Italian shipbuilder’s Technical and R&D vice president, Paolo Bertetti. Earlier this month Sanlorenzo revealed plans to construct a 50m superyacht equipped with hydrogen fuel cells that generate electricity from reformed methanol.

The project, due for completion in 2024, will have fuel cells designed and built by Siemens Energy. Bertetti told SYI: “What we are developing with Siemens Energy, is totally new and is specifically designed for superyachts with tight spaces, where more conventional solutions cannot be accommodated.”

The first yacht has been purchased by Sanlorenzo’s CEO, Massimo Perotti to accelerate development. According to the firm’s research, the hydrogen fuel cell solution path makes best use of the additional tank space required to maintain the same range, fuel availability and safety, while cutting its environmental impact.

“Since our R&D department presented this solution, Mr. Perotti realised that it could be a huge step forward for the whole industry. He has strongly believed in the project since inception and decided to be its forerunner,” said Bertetti. “To be pioneers, especially in experimenting with new technologies, important efforts and investments are required to develop new solutions for the future.”

The announcement was made as Sanlorenzo’s board of directors met to discuss the financial results for 2021. The firm’s backlog more than doubled in 2021 coming in at €915.6m. Net revenues from the sale of new yachts were €585.9m, up 28% compared with €457.7m in 2020.
