  • Hydrogen-powered passenger ferry in San Francisco Bay is possible, says Sandia study: Ferry boats, as are used around the world, can be powered by hydrogen fuel cells to dramatically reduce pollution, and the risk of diesel fuel spills. Research by Sandia National Labs show that it's feasible to build and operate a high-speed passenger ferry powered by fuel cells. The study focused on the Red and White fleet operating on the San Francisco Bay that serves commuters every day of the week. The conceptual specification was a ship carrying 150 passengers, with a 50-mile round trip, and at speeds up to 35 knots. Refueling would happen midday while the ships were less busy (outside commute hours). Both the American Bureau of Shipping and the US Coast Guard reviewed the plan and gave a thumbs-up.
  • Optimizing hydrogen-powered passenger ferries focus of Sandia Labs study : Building on earlier research into hydrogen fuel cell powered ferries, Sandia National Labs scientists are working to optimize the design. The design in the previous phase, 150 passengers and a 35 knot speed, turned out to be an outlier compared to other passenger ferries used in the USA. This was both a faster-than-normal ferry, and carrying fewer-than-normal passengers.
  • Sandia National Labs developing hydrogen fuel cell boat: Ships at sea no longer must be powered by Diesel fuel. Research led by Sandia National Labs shows that hydrogen fuel cells can be used instead. An accident need not necessitate spilling toxic polluting diesel fuel into the water, because spilled hydrogen cleans itself up automatically dissipating into the atmosphere with no harm, and the exhaust is not toxic but is instead pure water. The work at present is about designing research vessels that run on hydrogen, but the team is also interested in other vessels. An earlier effort had focused on ferry boats such as are used on San Francisco Bay to shuttle around commuters. The result is the Zero-V research vessel pictured here.
  • Toyota and Shell one step closer to a hydrogen refueling network in California: Fuel cell vehicles are supposedly the solution that will one day eliminate the need for battery electric vehicles. What's missed is the expense for hydrogen refueling stations (over $1.5 million apiece) versus the much lower cost for DC fast charging of battery electric vehicles (under $100,000). That means the same pool of money could build a whole lot more DC fast charging stations than hydrogen. The $16 million here to build 7 hydrogen stations could build 160 or more DC fast charging stations.
