When it Comes to Workboat Engines, the Future is Flexible
Vessel owners are making new fuel choices, but increasingly, they have options to help reduce the risk of doing so.The latest engine developments aim to make it easier for owners to avoid the chicken-and-egg fuel price and availability risks of new fuels.As Roger Holm, President of Wärtsilä Marine and Executive Vice President at Wärtsilä Corporation recently pointed out, the challenge is that owners won’t commit to a fuel today that is expensive, only produced in small quantities and may be usurped by another fuel that scales faster and more affordably.

Energy Storage Systems Continue to Expand in North American Maritime Markets
North America is increasingly adopting energy storage systems (ESS) to use in combination with combustion engines or as the sole energy carrier in fully electric-powered systems.We clearly see a transition from ‘consideration’ to ‘execution’ of hybrid and all-electric maritime projects. Stakeholders want to explore how to make vessels more energy efficient and less polluting. Corvus Energy has deployed over half of the ESSs aboard vessels globally, totaling over 300 megawatt hours (MWh).In North America, Corvus has deployed 24 MWh of energy storage capacity, and there are 13 vessels under U.S.
