Hybrid Carbon-free electrically driven fishing longliner with low power methanol combustion engine for propulsion back-up and auxiliary equipment

Project description

First-of-its-kind fishing vessel that runs on renewable energy

Iceland-based company NAVIS specialises in naval architecture and marine engineering. With the help of the EU-funded RENShip project, it aims to develop a fishing vessel that runs on renewable energy. The work will build on the outcomes of a previous project run by NAVIS, which demonstrated a hybrid ship that combines fuel-powered and electric engines. The new fishing vessel will have a small combustion engine powered by methanol and a set of lithium batteries. The latter will be connected to onboard wind turbines and solar panels. It will be the first totally operated by renewable energy and the smallest fishing vessel powered by a hybrid propulsion system.


Out of NAVIS high commitment with a greener shipbuilding industry and our many years’ experience in naval architecture and engineering design, we have developed a 100% renewable energy propelled vessel. With the objective of maximizing operational efficiency and green energy whilst improving the handling of the catch, we have taken the current hybrid ship concept to a step further and developed RENShip. Our innovative RENShip is a small fishing long liner vessel powered by a revolutionary hybrid system including a single small combustion engine powered by methanol and a set of lithium batteries, connected to onboard wind turbine and solar panels for supercharging.
European fishing fleets are major oil consumers and so, they are greatly responsible for global greenhouse gas emissions from the world’s fleets. Moreover, current ship engines are excessively powerful diesel engines of 50-60% efficiency, resulting in excess of fuel combustion and cost (specially as fossil fuels prices increase over 50%), as well as causing noise and vibration impacting fishing effectiveness and crew’s health. With benefits such as >30% reduction in fuel consumption and associated CO2 emissions and air pollutants (SOx, NOx), considerable reduction in underwater noise, access to fish product’s ecolabels and new tailored displacement hull form, RENship demonstrates its great business opportunity and potential to shift current shipping practices towards efficiency, lower costs and greener operation.
Currently located at TRL6, we will integrate all components into a new design to build a pilot ship and validate RENShip in operational conditions, reaching TRL9. RENShip will be the first vessel totally operated by renewable energy and the smallest fishing vessel running with a hybrid propulsion system. There is currently one RENShip design we plan to take to the market with an average market price of €2M (10% profit margin), which will report €100K per boat to NAVIS.
