Pesa And PKN Orlen To Develop Hydrogen Fuel Cell Trains

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

This is the introductory paragraph.

Rolling stock manufacturer Pesa and energy company PKN Orlen signed a letter of intent to develop hydrogen fuel cell trains on December 12.

I am pleased that Poland appears to be turning to trains that emit less carbon, but I do worry about how the hydrogen is produced.

It appears the Dutch are moving towards green hydrogen, which is produced by the electrolysis of water using electricity produced by offshore wind farms.

But how are the Poles producing their hydrogen?

I did find this article on biznewsalert.com, which is entitled Poland Wants To Be A Hydrogen Kuwait. P2G Can Help.

This is the introductory sentence.

Hydrogen could drive low-carbon transport and also help reduce CO2 emissions. Although it is a distant perspective for now, the production of the element could support onshore wind farms.

It does appear that the Poles are thinking along lines, that will reduce carbon emissions.

What is P2G?

P2G or Power-to-Gas has an informative Wikipedia entry.

This is the first paragraph, which outlines the process.

Power-to-gas (often abbreviated P2G) is a technology that converts electrical power to a gas fuel. When using surplus power from wind generation, the concept is sometimes called windgas. There are currently three methods in use; all use electricity to split water into hydrogen and oxygen by means of electrolysis.

There certainly a lot of activity in the sector.

My Experience Of Polish Transport

Poland is a large country with an extensive rail system. I have travelled long distances across the country and many of the passenger trains are electric.

I can’t remember seeing a freight train, but I do remember large numbers of diesel trucks moving freight across the country.

Conclusion

Hydrogen could be a very important fuel for transport in Poland.

Poland Investigates Use Of Hydrogen Fuel For Rail Freight

The title of this post is the same as that of this article in the International Railway Journal.

This first paragraph, outlines the project.

Polish coal mining company JSW and national rail freight operator PKP Cargo have agreed to cooperate to research, analyse and possibly produce new types of hydrogen-powered freight wagons and shunting locomotives.

Note that one of the collaborating companies is a coal company.

Statements later in the article indicate that JSW can create commercial quantities of hydrogen, as a by-product of making coke.

Some of us of a certain age, still remember coal gas, which was replaced by natural gas from the North Sea in the 1970s.

It looks like Poland are still using the same process to obtain coke and probably other products like coal tar, sulphur and ammonia.

According to Wikipedia, UK coal gas had the following composition.

  • Hydrogen 50%
  • Methane 35%
  • Carbon monoxide 10%
  • Ethylene 5%

It was one of the suicide methods of choice for the unhappily married. I don’t miss the foul stuff, with its poisonous carbon monoxide.

But as you can see, it does have a high percentage of hydrogen!

Conclusion

I’m not a fan of using coal gas, but these two Polish companies are another group investigating the use of hydrogen as a method of powering trains and other rail vehicles.
