HS2 Smashes Carbon Target

The title of this post, is the same as that of this article on Rail Engineer.

This is a must-read article which explains how the various companies building High Speed Two are progressing in making all of the work sites diesel-free.

GeoPura is mentioned in the article and on this page on GeoPura’s case studies, which is entitled HS2 Reveals Successful Results Of Hydrogen Generator Trial, full details of the trial are given.

An HS2 construction site in London has held successful trials for two zero-emissions hydrogen fuel cell-based electricity generators – cutting carbon and improving air quality for workers and the local community.

The two GeoPura 250kVA hydrogen power units (HPUs) were trialled over the last year at HS2’s Victoria Road Crossover Box in Ealing, as a direct replacement for diesel generators to power machinery on the site.

There is also this video from High Speed Two.


  1. The use of electric cranes, diggers, dump trucks.
  2. The red trailer with lots of small cylinders, which is used to supply hydrogen.
  3. HS2 are also using HVO and flywheels to store energy.
  4. The video is narrated by HS2’s Air Quality Manager. If every project had one of these, it must surely speed decarbonisation.

We need more electric construction.

  1. Its rather wonderfull that having the Railways on strike has lowered UK Carbon Emissions and reduced the possibility of rolling Electricity Black outs. Is Mr. Lynch on the government payroll? Cutting down Ancient Forest to build HS2 was a bad idea, and increased carbon emissions.

  2. […] High Speed Two are doing this and I wrote about it in HS2 Smashes Carbon Target. […]
