New California Hydrogen Fuel Plant Will Use Wood Waste

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

  • It is being developed by a company called Mote.
  • They are spending $100 million on the development.
  • The plant will be built at Bakersfield in California.

The Mote web site is worth a look.

It explains their process with a good graphic.

  • Wood waste is gasified and processed, so that the carbon dioxide and hydrogen are separated.
  • The hydrogen is used as normal.
  • The carbon dioxide is stored.

The company claims the process is carbon negative.

They also give figures for their first facility.

  • It will remove 150,000 tonnes of carbon from the atmosphere every year.
  • It will produce twenty tonnes of hydrogen per day.

Fluor, who are one of the United States largest construction companies are involved.

Conclusion

In Can The UK Have A Capacity To Create Five GW Of Green Hydrogen?, I said the following.

Ryze Hydrogen are building the Herne Bay electrolyser.

  • It will consume 23 MW of solar and wind power.
  • It will produce ten tonnes of hydrogen per day.

The electrolyser will consume 552 MWh to produce ten tonnes of hydrogen, so creating one tonne of hydrogen needs 55.2 MWh of electricity.

This would mean that Mote’s Bakersfield plant is twice the size in terms of hydrogen production, than the electrolyser at Herne Bay.

Looking up Bakersfield on Wikipedia, it appears that there is a lot of agriculture in the area and it ranks in the top five in the States.

I’d like to learn more about this company and their method of hydrogen production.

Does it count as green hydrogen, as it appears the carbon dioxide is stored.

Given the agriculture in the area, could the carbon dioxide be fed to plants growing in greenhouses.

What Will Happen To Northern’s Class 195 Trains?

Northern’s Class 195 trains could be a problem in the future.

  • They are diesel multiple units.
  • There are twenty-five two-car trains and thirty-three three-car trains.
  • All cars have a Rolls-Royce MTU 6H1800R85L diesel engine, that drives the train through a ZF EcoLife 6-speed transmission.
  • They are 100 mph trains, which is adequate for the routes they serve.
  • According to Wikipedia, the trains are designed for a lifespan of thirty-five years, which takes the trains past the date, when it is intended that all trains should be zero-carbon.

It looks to me, that a plan will be needed to decarbonise these trains, as they are probably too new and costly to scrap.

These are possibilities to upgrade them to zero-carbon.

Rebuild as Class 331 Electric Trains

The design of the Class 195 trains is based on the same platform as that of the Class 331 trains.

I would expect that it could be possible to rebuild the Class 195 trains as Class 331 trains.

But it would be an expensive and disruptive process and would require a lot of electrification.

Some battery-electric versions could be created to cut the need for electrification.

Run The Trains On Net-Zero Hydrogenated Vegetable Oil Or Other Fuels

In Powered By HVO, I wrote about research going on into the use of Hydrogenated Vegetable Oil or HVO.

There is also ongoing research into other net-zero fuels that can be used in a diesel engine.

The process used by Velocys to create sustainable aviation fuel can also be used to produce diesel from various sources like disposable nappies, household waste and scrap wood.

Run The Trains On A Dual Fuel Basis With Hydrogen

In Grand Central DMU To Be Used For Dual-Fuel Trial, I talk about how Grand Central in collaboration with a company called G-volution are running experiments with dual-fuelling a Class 180 train. G-volution state that they could dual fuel with hydrogen using their technology.

The Class 180 trains have Cummins engines, but I suspect G-volution’s technology or something similar could be applied to the Rolls-Royce MTU engines in the Class 195 trains.

This could be a very promising route.

Convert The Diesel Engines To Run On Hydrogen

Cummins and JCB have developed internal combustion engines, that can run on hydrogen. I would be very surprised if Rolls-Royce MTU are not developing this technology.

Conclusion

There are options to convert the Class 195 trains into low or zero-carbon trains.
