Using a hybrid of LNG and battery power has become an increasingly popular strategy for ship owners. Hybrid ships save up to 30% on fuel, see reduced maintenance requirements since for much more of the time the engines are running at a steady rate, and can switch to battery when entering and leaving port to easily complying with just about any ECA regulation in existence. Norway recently issued a law that ships travelling in its UNESCO World Heritage Fjords must have no emissions of any kind. The law becomes effective in 2026 and newer vessels are being designed to meet this standard – at least during the time it takes to transit the fjords. Corvus and PBES are currently working on products that will reduce battery size, increase energy storage, and require less cooling.
