Antofagasta becomes latest Charge on Innovation Challenge patron

Antofagasta, as part of its sustainability efforts, has joined the Charge On Innovation Challenge as a patron.

The initiative, which counts BHP, Rio Tinto and Vale as founding patrons, seeks to develop solutions to charge the batteries of electric mining trucks safely, quickly and sustainably. This is essential in order to replace the use of diesel in these trucks and the emissions it produces, the challenge organisers say.

The goal is to enable trucks of 220 t or more to stop using diesel and run on electric batteries, just like other electric vehicles. In order to achieve this, it is essential to develop a battery charging system that does not use polluting fuels and, at the same time, allows the extraction trucks to operate as they usually do.

Today there are already efforts underway to develop and use electric trucks, but those are for trucks of a smaller tonnage (100 t) which can regenerate their own energy, Charge on Innovation says. The collaborative work with the Charge On Innovation Challenge seeks to develop solutions for larger trucks.

Iván Arriagada, CEO of Antofagasta, said: “As a mining group focused on innovation, we are interested in collaborating and contributing to the development of the industry for the future. That is why we decided to participate in this challenge, which is key to being able to use electric trucks and significantly reduce greenhouse gas emissions.”

As part of its Climate Change Strategy, from 2022, the electricity supplying Antofagasta companies will come from renewable sources. Antofagasta’s Zaldívar mine has been operating from clean energy sources since July 2020.

Thanks to these advances and other measures adopted by the company, Antofagasta was able to reduce its greenhouse gas emissions by more than 580,000 t since 2018. Its new goal is to decrease those emissions by an additional 30% between now and 2025.

The Charge On Innovation Challenge was launched by BHP, Vale and Rio Tinto in partnership with Austmine. It has since added Roy Hill, Teck, Boliden and Thiess as additional patrons.
