HS2 LPG generator trial celebrates emissions cuts

06 September 2022/Categories: Rail

HS2 is trialling an OakTec standalone Clean Air Gas Engine (CAGE) generator at Euston, which has delivered a reduction in emissions. 

Following the trial of the new Clean Air Gas Engine (CAGE) integrated into a solar-battery hybrid power system, the innovation is being trialled by HS2’s contractor Mace Dragados on a site at Euston and has exceeded its targets.

Emission testing of the unit showed significant reduction in harmful pollutants, up to 95% reduction in NOx (Nitrogen Oxides) and particulate exhaust emissions, when compared to the output of a conventional diesel-fuelled welfare unit power system.

Andrea Davidson, HS2’s Air Quality Manager said:

“We aim to make the HS2 project net zero carbon from 2035, with the target of having all our construction sites diesel-free by 2029. To achieve these ambitions, HS2 is working closely with UK manufacturers and researchers to trial new technologies, to help encourage the construction sector to move away from diesel and reduce greenhouse gas emissions. The successful results of the CAGE trials are key milestones in achieving this, and we’re looking forward to seeing products like this rolled out across our sites in the future.”

The emission test results clearly demonstrate that the CAGE-generator operating on LPG achieved the EU Stage V NRE and EU Stage V NRS emissions standards for all pollutants across all test loads.
