Hydrogen from sea water

Our revolutionary technology introduces the first electrolyser to use sea water to produce hydrogen. No desalination, no purification to produce the pure water required by existing electrolysers and no toxic waste. A world first for a greener planet.

Hydrogen from sea water

Our revolutionary technology introduces the first electrolyser to use sea water to produce hydrogen. No desalination, no purification, no toxic waste — improvements over existing electrolysis technology to produce the pure water required by existing electrolysers and no toxic waste. A world first for a greener planet.

Cheap/cost neutral hydrogen

Removing the need for a desalination unit reduces overheads. Environmentally friendly by-products have a range of applications which offset costs. That makes hydrogen green and cheap. We’d go so far as to say we’d give it away for free.

Business applications

sHYp’s electrolysers will have a variety of business applications. In addition to hydrogen production they can simultaneously be used for magnesium and silica production or CO2 capture, and ballast water treatment. They can be located in ports, on board vessels and FPSOs and offshore to harness surplus electricity generated by wind, wave and solar.

Example: Offshore wind

A sHYp electrolyser located on an offshore turbine would use sea water to convert surplus electricity into green hydrogen which is pumped ashore for storage and re-electrification. No desalination needed, no toxic by-products.

Pilot projects

Ports around the world from Europe to the Middle East to Australia will pilot our electrolyser units. Products will be used for a variety of applications, with a focus on shipping and heavy transport. Hydrogen is an emission-free, clean, cost-effective fuel.




sHYp technology

A membraneless electrolyser using our industry-leading technology splits sea water into hydrogen and oxygen.

Existing electrolysers operate on high purity fresh water which is achieved through purification. If sea water is used, the by-product created from desalination by conventional electrolysis is brine, a toxic salt sludge which is an environmental hazard.

The by-products generated by sHYp’s sea water electrolysis are environmentally friendly and financially valuable. Green hydrogen from sea water.


Carl Fischer

Co-founder & CEO

Carl is an economist who previously founded, grew and exited two Fintech companies.

He worked with Nobel Peace Prize Laureate M. Yunus on his Social Success Note, created the first Public Private Impact Investment project for the Philadelphia Water Department and a Social Impact Bond against homelessness in Baltimore.

While working for ED&F Man in London, Carl came in touch with the shipping industry and learned about its contribution to global pollution and its related challenges regarding upcoming ballast water treatment and emission regulations.

When he came across the technology developed by his co-founder Professor Daniel Esposito, he knew a solution was at hand. That’s when sHYp was born.

Professor Daniel Esposito

Co-founder & Advisor

Dan, an Associate Professor of Chemical Engineering at Columbia University, New York, developed the technology at the heart of sHYp.

He began his research into membraneless electrolysers at Columbia in 2016. As a result of his research, he received a Faculty Early Career Development (CAREER) award from the National Science Foundation (NSF) in 2018.

This five-year scholarship is the NSF’s most prestigious award to support the early career development activities of researchers.

Using the NSF funding, Dan set up his own research group at the university: the Solar Fuels Engineering Lab, part of the Department of Chemical Engineering.

Tobias Janning


Tobias is a project finance and business development professional with 6 years of experience with a German maritime project developer being responsible for investor relations, project sourcing and execution.

Tobias has studied B.Sc. Maritime Management at Hamburg School of Business Administration and Hang Seng University of Hong Kong and M.Sc. Energy, Trade and Finance at CASS Business School. He has received the Promotional Award of the Hanse Association for his thesis on the use of hydrogen in maritime applications and went on to represent the Hamburg Ministry of Economics, Transport and Innovation as part of a delegate team at SHFCA in Aberdeen, Scotland. Tobias joined sHYp in September 2020.

Liz Fletcher


Liz is a mechanical engineer, who has spent the past few years working at a maritime consulting firm in Rotterdam, NL.

She has worked with a diverse group of companies in the maritime technology space from onboard sensor systems for optimized sailing speed to sub-surface imaging for offshore windfarm development. Most recently, she worked designing mechanical deck equipment for construction vessels.

Liz is motivated to find a more sustainable future for the maritime industry and is excited to make sHYp a part of this future. As CSO, Liz works to coordinate engineering efforts of sHYp, from the lab to production.

Jennie Morrison


Jennie is a chemist with a 1st Class Honours degree on Applied Chemistry and a PhD from The University of Aberdeen in sequestration of CO2 into magnesium hydroxy carbonate hydrates. Novel building materials were developed from one of these carbonates.

She has previous experience in the oil industry in Aberdeen and in environmental monitoring.

Jennie will work with university research groups to coordinate sHYp's electrolyser development and will herself concentrate on carbon capture from sea water, using the effluent streams from sHYp's membraneless electrolyser.
