Hycamite’s tech for onboard hydrogen production gets DNV nod
Finnish cleantech company Hycamite has received an approval in principle (AiP) from classification society DNV for the concept design of a carbon capture system that produces hydrogen from LNG onboard vessels.

DNV has approved the concept design of a pre-combustion, solid-form carbon capture system (CCS) that produces hydrogen from LNG onboard vessels, using Hycamite’s technology.
The “Thermo-Catalytic Decomposition (TCD) technology” refers to a process that breaks down methane – the main component of LNG, into hydrogen gas and solid carbon using heat and a special catalyst in an oxygen-free environment.
This method produces hydrogen without releasing carbon dioxide, making it a zero-emission alternative to conventional hydrogen production.
The methane-splitting technology will generate solid carbon byproducts like graphite and carbon nanofibers, Hycamite said, adding it will “enable the use of hydrogen onboard larger LNG-powered deep-sea vessels.”
The onboard system will allow ships to convert LNG into hydrogen during operation, “providing a clean fuel source for dual-fuel engines or fuel cells,” the company said.
Meanwhile, the solid carbon will be captured and stored onboard. By capturing carbon in solid form, vessels will be able to create a circular carbon economy while at sea, according to Hycamite.
“If biomethane is used as a fuel, operation of the vessel is potentially carbon negative,” it added.
“This AiP is the first time we have recognized a pre-combustion carbon capture tehe alternative fuels and piping systems section at DNV Maritime.
