Emission reductions achieved in locomotive using AHT hydrogen generator

Advanced Hydrogen Technologies (AHT) Group’s independent trial has seen its hydrogen generator reduce emissions on a Class 08 locomotive in the UK.

Under a joint venture partnership with Harry Needle Railroad Company (HNRC), the first week of the trial used AHT’s R4 Generator to “clean” the train by removing residual carbon build up, before a carbon capture device was added.

The study reported overall gas emissions were reduced by 22% and heavy particulates by 20%, with diesel efficiency savings of 8% also achieved.

“Rail is one of the sectors under most scrutiny,” said AHT CEO, Ben Kattenhorn. “But Engine Carbon Clean and Capture offers an immediate solution – also restoring engine efficiency and power, lowering maintenance costs, extending the lifespan of assets and aligning with the new ESG requirements of the International Financial Reporting Standards Mandate.”

Kattenhorn added, “We also know these figures get even better over time, because a recent 18-month study on heavy goods vehicles (HGVs) reduced the worst emissions and particulates by over 91%.”

During the testing, a baseline reading was compared with those generated once the R4 hydrogen generator was fitted, which determined the average 8% fuel saving. In addition, 27% of carbon monoxide was reduced, with 8% CO2, 22% nitric oxide, 12% nitrogen dioxide and 39% formaldehyde also reduced.

Marcus Mayers of the HNRC, said, “This was the ideal opportunity to solve the pressing issue of how to measure and quantify the benefits of hydrogen, which has been holding us back for years.

“Access to both AHT’s specialist technology and [the] Black Country Innovative Manufacturing Organisation’s (BCIMO) outstanding testing facilities has given us the data and backing we need to have a proven business investment case for upgrading our locomotives.”
