California’s cap-and-trade dollars are building a hydrogen fuel cell boat

All aboard: construction of a hydrogen fuel cell boat, with aims to be the first of its kind to run commercially, was announced on Thursday in San Francisco.

A startup called Golden Gate Zero Emission Marine (GGZEM) held a keel-laying ceremony on Thursday for its new, 70-foot hydrogen fuel cell ferry. The keel-laying ceremony marks the beginning of the construction of a vessel, and GGZEM expects that it will be completed by September 2019.

The boat, which will be called the Water-Go-Round, will likely be the first hydrogen fuel cell boat to run commercially, ferrying people around the San Francisco Bay. Generally, ferries tend to be diesel-powered, creating significant noise underwater, as well as greenhouse gas emissions and potential marine pollution from spills. By contrast, a hydrogen fuel cell boat would be quieter, and its only emissions while operating in the water would be more water.

An industrial estate on the outskirts of a sleepy spa town in deepest Powys, Wales, may not strike you as the obvious place to find an ambitious little hydrogen vehicle maker with plans to revolutionise the way we power, drive, and own our cars. But it shouldn’t come as that much of a surprise.

Why not? Well, if you drive seventy-five miles to the south-west from Riversimple’s HQ in Llandrindod Wells, you end up in Swansea, once the home of William Robert Grove who in 1842 pretty much invented the hydrogen fuel cell. And it’s a hydrogen fuel cell that part-powers the Rasa, Riversimple’s funky little two-seater prototype.

“Part-powers?” I hear you ask. While the majority of electric and hydrogen cars currently on the market are essentially conventional designs with battery or fuel-cell-and-battery power sources, the Rasa—the name comes from tabula rasa, the Latin for blank or clean slate—is the result of altogether more clever thinking. I’m inclined to use a word I usually avoid like the plague—holistic—to describe Riversimple’s view of automotive design.
