Proton Motor debuts first fuel cell passenger ship

The hybrid system uses a two fuel cells, a gel battery and an ultracapacitor, all managed by software designed to improve efficiency, Proton says.

Here's the fuel cell system being installed in the ship in July 2008.

Proton Motor developed a hydrogen fuel-cell system to power this passenger ship, the Alsterwasser, which debuted in Hamburg, Germany, today.

Proton Motor debuts first fuel cell passenger ship

Hybrid system powers 100-passenger ferry with ultracapacitor, gel batteries and hydrogen fuel cells.
The ship billed as the first fuel cell-powered passenger vessel in the world took its maiden voyage today in Hamburg, Germany.

The zero-emissions boat, dubbed the ZemShip, is expected to operate in a
test mode until later this year. At that time, the city plans to allow passengers to ride the ship on the Alster and Elbe rivers.

The fuel cell system was developed by Proton Motor, a wholly-owned subsidiary of Puchheim, Germany-based Proton Power Systems (LSE: PPS.L). Proton now plans to leverage the experience to break into a significant market for clean-running boats, CEO Thomas Melczer told the Cleantech Group today.

"The market for small tourist ships is quite large in Hamburg, London, Amsterdam, Dubai, everywhere," Melczer said. "There's interest in Europe for these ships, especially in lakes that supply drinking water where you don’t want diesel engines running."

It's too early to determine the price tag for the company's fuel cell-powered ships, said Joachim Kroemer, sales director of Protus.

"We expect to begin discussions soon with potential customers, and the price strongly depends on how many systems will be produced," Kroemere said. "We'll try to get five-to-10 of these systems developed in the same time frame, and then we will be able to get a 50 percent cost reduction."

Proton is also exploring the use of the fuel cell technology for small pickup trucks, buses, forklifts and stationary power systems, Melczer said. The company is working with Wilhelm Karmann to build a zero-emission, light-duty commercial vehicle (see Proton, Karmann to build hybrid fuel cell truck).

Those systems could use lithium ion, nickel metal hydride or nickel cadmium batteries, but Proton was restricted to using a lead acid gel battery for the ship's system because of environmental concerns.

A software system will manage the power supply to make the ship about twice as fuel-efficient as a standard diesel ship, Kroemere said. The ultracapacitor will work during peak demand, while the lead gel battery will be used for lower energy demands. The two 48-kilowatt fuel cells will drive the ship during the majority of its journey, Kroemere said. Germanischer Lloyd has certified the system for maritime operation.

The system is designed to use 50 kilograms (110 pounds) of gaseous hydrogen to operate for three, 8-hour days, Kroemere said.

A new, hydrogen fueling station installed by German hydrogen manufacturer Linde Group will supply the ship with its main source of fuel.

The ZemShip resulted from a two-year consortium of companies and government agencies, including the European Union, which contributed €2.4 million to develop and operate the ship through 2010.

Although the companies say the project is the first passenger ship powered by fuel cells, the technology has long been examined for use in submarines (see Submarines: ideal fuel cell vehicles). Because fuel cells produce no exhaust heat, submarines can use the technology to evade detection.

Proton Power's shares were up £2.75 in Friday's trading, or 55 percent, to £7.75. Proton was initially listed on a submarket of the London Stock Exchange's in October 2006 valued at £96 per share, but shares have been in a steep decline since March and have bottomed out at £5 several times this summer.
