Red and White will also be adding 1.5 million sq. ft. of solar panels to provide totally clean electricity to the battery systems. “If we need to, we will also take power off the grid, but that’s hydropower here in San Francisco, so we’ll be getting clean power from the grid and from solar, so we’ll have a really clean boat,” said Escher. With a properly sized bank of batteries shoreside, the recharging of the Enhydra, even with more batteries, is envisioned to take just eight or nine minutes. “All we are doing is copying the Norwegians,” said Escher. “They’ve been doing some fast charging for several years on allelectric ferries.” “Shore-based power is much more efficient and has lower carbon content than the stuff that comes from a diesel,” said Allan Grant of Corvus Energy in Vancouver, British Columbia. “It’s also less expensive. 4

They will still have the diesels on board, so if they were running a particularly long charter or something like that and the ‘tank’ gets low, it turns back into a hybrid.” Grant added that getting power from the grid makes it more efficient by helping fully utilize the available capacity. “It increases the loading on that [grid] circuit which increases its efficiency. The circuit will either be constantly recharging the batteries or recharging the ship.” Essentially, a hybrid system is about efficiency. Diesel engines are most efficient and have the lowest emissions at 60% to 80% loading, 80% being optimal, according to Grant. So, when engines would be idling or running at a low rpm, that’s the right time to get the needed power from batteries, which should be charged when the engines are running at optimal loading. This type of power-production-
storage-consumption strategy is starting to be used in lots of maritime applications, said Grant. “Cruise ships are stepping up and saying they want to put massive systems on board, partially to go into environmentally sensitive areas like Norwegian fjords or into the Arctic or Antarctic. Or to be more fuel efficient. From what we’ve seen, all of the cruise ships are heading into that direction, using similar hybrid systems.” “For at least a while, our boatyard has more experience with this electric hybrid type system than any other boatyard in the country,” said Matt Mullet, All American’s president. “All American is working to stay at the forefront of the decarbonization movement in the maritime industry, and the lithium-ion hybrid electric propulsion system on the Enhydra is a step in the right direction.”
