SEA-LNG member and technology group Wartsila has entered into a joint development agreement with Hycamite TCD Technologies, a privately-owned Finnish company specialising in the development of a pioneering technology for producing clean hydrogen and solid carbon from methane, according to SEA-LNG's release. The two companies will work together to enable cost-effective production of hydrogen from LNG onboard marine vessels. The concept design will be ready by mid-2023 and the prototype testing unit will be ready during the second half of 2024.
The concept will allow the existing LNG infrastructure to be utilised and enable production of hydrogen onboard in combination with Wartsila’s LNGPac Fuel Gas Supply System. By producing hydrogen onboard and blending it with LNG, the current range of fuel flexible Wärtsilä dual-fuel (DF) engines can reduce the vessel’s overall carbon dioxide and methane slip emissions. Alternatively, the hydrogen can also be used in fuel cells onboard.
The by-product from the process is solid carbon that, unlike conventional technologies which produce carbon-dioxide (CO2) as a by-product, can more easily be stored and managed onboard. The carbon produced consists of high-grade allotropes, like industrial graphite and carbon nanotubes, thereby offering a possible additional revenue stream.
The technology can in principle be applied for all vessels operating with LNG fuel. When using bioLNG, this solution enables even power generation on board ships with a negative carbon footprint.
