Thirsty High-Rollers … Mining’s Heavy Haulers Prime Candidates For Hydrogen Conversion

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

You understand, what the author means about mining’s heavy haulers, when you open the article.

This paragraph describes their carbon emissions.

One large scale dump truck, depending on the haul road it is using, will use between 100 and 140 litres of diesel per 100km. These vehicles operate all day every day except for maintenance down time. That’s between 260kg and 360kg of CO2 per 100km per truck.
Large open pit mines have tens of these vehicles operating continuously, so the numbers build up very quickly.

The author then goes on to say why, that converting these vehicles to green hydrogen makes a lot of sense.

The dump trucks are already diesel/electric, which means that the diesel generator can be replaced with a hydrogen fuel cell and a battery.

Mining giant; Anglo-American will be introducing a prototype hydrogen-powered dump truck at a platinum mine in South Africa this year.

These paragraphs describe the transmission.

The vehicle, which is called a fuel cell electric vehicle (FCEV) haul truck, will be powered by a hydrogen fuel cell module paired with Williams Advanced Engineering’s scalable high-power modular lithium-ion battery system. Williams provides batteries for FIA’s E-Formula motorsport.

This arrangement will replace the existing vehicle’s diesel engine, delivering in excess of 1MWh of energy storage. The battery system will be capable of recovering energy through regenerative braking as the haul truck travels downhill.

Note that the truck has more energy storage than is proposed for a four-car battery-electric train, like the Class 756 train, which has only 600 kWh.

The author finishes with this concluding paragraph.

With the major mining companies focusing on making significant strides in decarbonisation by 2030 expect there to be more announcements such as this focusing this “low hanging fruit” for the mining industry’s to materially reduce its carbon foot print.

Reading this, I can’t help feeling that replacement of a Class 66 locomotive with a zero-carbon hydrogen-battery-electric hybrid unit could be possible.
