H2OzBus Project: Deploying Hydrogen Fuel Cell Bus Fleets For Public Transport Across Australia

The title of the this post, is the same as that of this Press Release from ITM Power.

This is the introductory paragraph.

ITM Power, the energy storage and clean fuel company, is pleased to announce the formation of the H2OzBus Project (“the Project”) and the signing of a memorandum of understanding with strategic partners (“the Consortium”).  The Consortium comprises Transit Systems, part of the SeaLink Travel Group, Ballard Power Systems, BOC Limited, Palisade Investment Partners and ITM Power.  The Consortium partners have signed a memorandum of understanding as a further step in evaluating and demonstrating the concept of hydrogen fuel cell electric buses for use in public bus transport in Australia.

Some further points from the Press Release.

  • Initially, a hundred buses will be deployed.
  • The buses appear to be being built in Australia.
  • Ten locations are being considered for the buses.

It looks to be a very sensible project.

Investors Hit The Gas On Hydrogen Producers

The title of this post is the same as that of this article on the FT.

The sub headline is.

Hydrogen producers leap on hopes of fossil fuel death.

The article then shows three share price graphs for ITM Power, PowerCell and Ballard Power Systems.

All prices are rising steeply.

A a small investor in the first company, I am pleased and I certainly got that call right!

Note that, the companies are British, Swedish and Canadian respectively.

Hydrogen Fuel Cell Company Shares Take Off After 4 Decades Of Declines

The title of this post is the same as that of this article on Hydrogen Fuel News.

Ballard Power Systems, is the company referred to in the article.

This London bus has a hydrogen fuel cell from Ballard.

Ballard Receives Order From Porterbrook for Fuel Cell Module to Power UK HydroFLEX Train

The title of this post is the same as this article on Cision.

The article says that the copy has been provided by Ballard.

This is the first paragraph.

VANCOUVER and DERBY, U.K., Dec. 13, 2018 /CNW/ – Ballard Power Systems (NASDAQ: BLDP; TSX: BLDP) today announced that it has received a purchase order from Porterbrook Leasing Company Limited (“Porterbrook”; http://www.porterbrook.co.uk), a leading participant in the rail leasing market, for an FCveloCity®-HD fuel cell module and related support to power a HydroFLEX train in the U.K.

The article says this about the HydroFLEX train.

The HydroFLEX will be the U.K.’s first fully sized hydrogen demonstrator train. It will showcase how hydrogen can be used to power a train that retains the ability to operate across existing electric routes, on either 3rd rail or 25kV overhead power. Testing and demonstration runs are planned for the summer of 2019 at RailLive, which will take place at Long Marston in Warwickshire.

That sounds like it could be a date for my diary.

Strictly A Demonstrator

In this article on Rail Engineer, which is entitled Hydroflex – The Next Iteration Of The Flex Concept,there is a section entitled Strictly A Demonstrator, from which this was taken.

In response to Rail Engineer’s questions, BCRRE said that the demonstrator version focuses on delivering an electric/hydrogen bi-mode to UK gauge.

So the HydroFLEX is more about research., which I believe is a good route.

  • My feelings on seeing the Alstom Coradia iLint in Germany, was that they had launched too early!
  • Getting a University to run a demonstrator might show up the smaller problems associated with a complex project.
  • Birmingham University may also have access to better mathematics and computing.
  • The interior of the train can be used for test equipment and hydrogen tanks.

I also suspect that a well-designed demonstrator could help with the repurposing of Porterbrook’s extensive fleet, by doing appropriate research.

The Fuel Cell

The Ballard fuel cell is a HD variant of their  FCveloCity family.

This page on the Ballard web site is the data sheet.

  • The fuel cells come in three sizes 60, 85 and 100 kW
  • The largest fuel cell would appear to be around 1.2 m x 1 m x 0.5 m and weigh around 400 Kg.
  • The fuel cell has an associated cooling subsystem, that can provide heat for the train.

It would appear that mounting the fuel cell under the train floor would be a feasible proposition. I would assume that the cell would be placed under one of the driver cars.

If you search the Internet, you’ll find there is a lot of fuel cell companies out there innovating like crazy and fighting for market share.

I don’t think there will be any problem with the fuel cell in the HydroFLEX train.

The Electrical System

The electrical system of the Class 319 train is simple.

  • There is a 750 VDC busbar, which connects to all four cars.
  • The busbar is fed by the 25 KVAC overhead or 750 VDC third-rail electrification.
  • One of the middle cars has the pantograph and the other has four 247.5 kW traction motors, which power the whole train.
  • There is no regenerative braking capability.
  • The two driver cars are only differentiated, by the seats installe by the operator.

It looks to me that this was a sensible piece of 1980s engineering by British Rail to create a low-cost dual-voltage train.

I do wonder, if the originator of this system is still hale and hearty. I suspect they are, as they certainly know how to design for a long life.

When Porterbrook commissioned the Class 769 train, the two diesel generators under the driver cars were connected into this busbar.

They didn’t add any energy storage to the train, although as I said in Brush Traction Signs Contract With Skeleton Technologies For Modules For Class 769 Trains, they have added SkelStart capacitors to start the diesel generators.

Effectively, the Class 769 train is an electric or diesel train, just like the Class 319 train is an overhead or third-rail electrificsation train.

Will the fuel cell of the HydroFLEX train be connected to the electrical system of the train in the same way?

Or will energy storage, be added to the drive train?

In a more advanced design, batteries or capacitors could be in the motored car.

  • They would be charged from the busbar.
  • They would power the traction motors.

If the traction motors, were to be changed to modern ones, that could perform regenerative braking, then this energy could be used to recharge the battery.

The Fuel Tank

I suspect as the train is for research, that a standard off-the-shelf hydrogen tank will be used.

This page on the Fuel Cells And Hydrogen Joint Undertaking, is entitled Improved Hydrogen Tanks For Fuel Cell Cars Of The Future.

This is the first paragraph.

The EU funded COPERNIC project, supported by the Fuel Cells and Hydrogen Joint Undertaking (FCH JU), succeeded in improving the quality of materials and design of hydrogen storage tanks for cars. It also made the manufacturing of these tanks more cost efficient, helping to make hydrogen cars a more viable and competitive option.

I think it is highly likely, that a well-designed hydrogen tank, could probably share the space under the driver car with the fuel cell.

If it can’t then as it’s a research project a few seats can be taken out.
