Study Evaluates Hybrid Power Systems for Reducing Emissions in Norwegian Fishing Vessels
A study evaluating hybrid power systems for a 10.5-meter gillnet vessel found that a hydrogen fuel cell-battery hybrid system can achieve near-zero operational emissions but has higher upstream emissions. The research highlighted that while this system can reduce direct emissions by up to 92% with low-carbon resources, its effectiveness varies based on electricity mix and component replacement rates. In contrast, a parallel hybrid system offers a 30% reduction in climate impact and utilizes more established technologies, making it a viable near-term solution for coastal vessels.

A study comparing onboard power systems for a 10.5-meter gillnet vessel indicates that a hydrogen fuel cell-battery hybrid system can achieve near-zero operational emissions but has higher upstream emissions. The research, part of the ZeroKyst KSP project, used a cradle-to-gate life cycle assessment (LCA) and identified that direct emissions from fuel combustion are the most detrimental to climate and health.
The hybrid system (SHS) can reduce direct emissions by up to 92% when sourced from low-carbon electricity and hydrogen from renewable resources in Norway. However, its effectiveness is influenced by factors such as electricity mix and component replacement rates.
Alternatively, the parallel hybrid system (PHS) offers a 30% reduction in climate impact and utilizes more established technologies, representing a viable near-term solution for coastal vessels. The study is pending journal submission.
