Hydrogen One and weight limitations. Batteries are only suitable for op- erations on ? xed routes where daily recharging is possible, and a towboat’s limited storage capacity restricts the use of pressurized or cryogenically stored gases as fuels. There are also very few dockside facilities to load such marine fuels, which severely constrains a vessel’s range and functionality.

Hydrogen One will be IMO 2030 compliant, and meet all requirements of the U.S. Coast Guard’s Subchapter M regulations. The ship has been designed by Elliott Bay De- sign Group using proven, ef? cient technology throughout, from ABB’s electrical power distribution and automation

Clean Canaveral

Sturgeon Bay, Wis. shipyard Fincantieri Bay Shipbuilding delivered the 340-ft. lique? ed natural gas (LNG) bunkering barge, Clean Canaveral, to Polaris New Energy on December 3. Built as part of an articulated tug and barge unit (ATB), the 5,500 cubic meter capacity barge is the largest of its kind ever built in the U.S., and will soon be followed by another barge of similar size for an af? liate of Polaris New Energy.

Built for coastwise transportation of LNG and to deliver

LNG as a clean maritime transportation fuel, the barge will be paired with a 4,000-hp Polaris tug ? tted with a JAK- 400 coupling system, being built at Master Boat Builders.

Built to ABS class, the barge is ? t with a cargo handling system designed and developed by Wärtsilä Gas Solutions
