WTFuel cell technology?

The Kitchener GO Line that runs through Weston / Mount Dennis will eventually be electrified. The Ontario Government recently announced through Transportation Minister Steven Del Duca that it would be spending ‘up to $200,000’ to study  alternatives to GO train electrification. A Mississauga company, Hydrogenics has managed to persuade the Minister that fuel cells may be the way to go instead of using overhead wires and electric trains.

How would it work? Hydrogen gas (yes, the gas used in the Hindenburg airship) would be produced by applying an electric current to water in a process known as electrolysis. The process is touted as green but unfortunately, electrolysis is notoriously inefficient so hydrogen produced for large projects such as a fleet of trains is manufactured from fossil fuels such as oil or natural gas – releasing large amounts of carbon dioxide and therefore not green at all.

Once hydrogen is made, problems continue. Storing it is hard. It must be compressed, cooled to a liquid or stored chemically – all of which are costly in terms of energy. Once stored, it must be transported to the trains.

The trains then would generate electricity from the hydrogen through the use of an on-board fuel cell of the type made by Hydrogenics. That means they would have a fuel cell electricity generator and a propulsion unit. Electric trains draw their current from overhead wires and only need a propulsion unit.

Surprisingly, adding to the negatives, a litre of gasoline contains about 64% more hydrogen than pure liquid hydrogen itself – yes, the hydrogen that was probably extracted at great cost from gasoline or diesel fuel.

Anyone who has been to Europe or ridden on Amtrak would know that electric trains there use overhead wires (called catenaries – in use since 1889) to supply power. The Eglinton Crosstown line opening in 2021 will use catenaries. It’s the current state of the art.

For some reason, either Mr. Del Duca wants to throw a $200,000 present to a company in the Liberal riding of Mississauga – Brampton South or he’s been completely misled about basic physics. Either scenario makes one wonder about the minister’s competence.

This video from Elon Musk sums up the inefficiencies and difficulties involved in getting hydrogen fuel cell technology to work. Yes, Mr. Musk has an axe to grind (battery technology) but his points are valid.

On the Ministry of Transportation’s GO Transit site, fuel cell technology is touted as electrification since the fuel cells generate electricity that drives the trains. If that’s the case, diesel trains can also be called electric since diesel engines generate electricity that drives the trains. Furthermore, since fuel cells are likely to need fossil fuels to provide the hydrogen, maybe we should call a conversion to fuel cell technology, fossilization.

Transit Planning Meeting

There’s a lot going on in Toronto transit-wise and especially in our neck of the woods. Six meetings are being held across the city to discuss transit – the closest will be at Richview Collegiate this Saturday.

Come and hear the latest transit ideas, updates on transit planning and construction going on throughout the city and contribute opinions on the direction the city, Metrolinx and the TTC should be taking. No doubt there will be considerable interest in the new UP Express fares as well as electrification of GO Trains.

  • Date: Saturday February 20
  • Place: Richview Collegiate, 1739 Islington Avenue
  • Time: 9:30 am to 11:30 am

Update:

Frances Nunziata says “My office has organized one to be held at the York Civic Centre on Feb. 29th at 7 pm.”

All day GO trains and electrification a pipe dream – Sullivan

Diesel powered for how long?

MP Mike Sullivan has called a ‘Community Town Hall’ meeting for Thursday 8th March at the York West Active Living Centre. Apparently Metrolinx has backed away from the number of GO trains promised because the Airport Link (using the same tracks but different platforms) will have priority. In addition, he would like community reaction  to the 27-year timeframe for electrifying the line as proposed in a recent provincial study. Davenport MPP Jonah Schein, will be on hand as NDP Transport Critic. Should be a lively meeting.

Date: Thursday March 8.

Time: 6:30

Place: York West Active Living Centre,1901 Weston Road.
