Efforts to bring battery-powered vessels to US waters are building steam, as a mix of state regulatory requirements and federal funding priorities fuel interest in emissions-cutting technology.

After already finding a place in the offshore vessel market on the US Gulf Coast, batteries are featuring in investment plans across the US ferry sector, and ports on the west coast are looking to electric tugs.

In the ferry market, electrification is expected to become customary for new vessels thanks to funding priorities of the Joe Biden administration.
