With rising fuel prices and impending environmental regulations, the pressure is on for more efficient and environmentally friendly ships. DNV in the joint industry project, FellowSHIP, developed a 330 kW fuel cell which was successfully installed, and demonstrated in smooth operation for more than 7000 hours on board the offshore supply vessel Viking Lady.
Fuel cell technology of this magnitude has never before been installed in a merchant vessel, and the project is innovative on a global scale. The achievements of the project include significantly reduced CO2 emissions, improved energy efficiency and zero emissions of harmful substances compared to conventional engine technology.
This recent success with fuel cell technology indicates that it is possible to lower the contribution from shipping to global warming. Introducing fuel cells to ships benefit human health and the environment by avoiding local consequences of air pollution. It can even completely eliminate CO2 emission if hydrogen from renewables becomes available.
According to DNVs expert on the field, Researcher Eirik Ovrum, fuel cells can have a viable future within shipping. “DNV has paved the way for safe and smooth introduction of fuel cells for ships. We recognize that it will take time before fuel cells can become a realistic on-board alternative, mostly restricted by costs, but the FellowSHIP project has taken some important first steps towards a future for fuel cells on ships.”
Although fuel cell technology is not new, this recent success means that it has become relevant to discuss the potential for fuel cells in shipping, as done in the present position paper from DNV.
