Members of the International Council on Mining and Metals are planning a joint effort to test hydrogen and other zero-emission technologies as mining companies try and shift away from diesel-fueled vehicles.

Members, which include producers BHP Group and Glencore Plc, are pitching sites to test technologies including electrolysis plants, trolley-assist haulage and regenerative braking, according to Rohitesh Dhawan, the group’s chief executive officer.

The group expects to choose 50 sites within the next two months to form a development network, the results of which will be shared with the rest of the industry according to Bloomburg News.

The mining industry uses more renewable energy to power its operations than in the past but has just begun testing prototype vehicles that are key to meeting net-zero emissions targets. Governments and investors have become more sensitive to environmental concerns in recent years.

The industry’s planned network follows a push to bring mining companies and manufacturers together to speed up the development of zero-emission vehicles. While mass availability of hydrogen and electric trucks is expected in 2027 — compared with an earlier projection of 2040 — Dhawan hopes to shorten that cycle further.

“We’re focused on what can we do as an industry to make sure that we adopt these and accelerate the deployment of them as quickly as possible,” he said in an interview on the sidelines of a conference in Peru. “Inevitably, that will mean working with national governments to figure out what their plans are.”
