Caterpillar highlights hydrogen storage and fuel cell plans at Arizona demonstration site

Caterpillar has been setting out how hydrogen storage and fuel cells will be integral to its future sustainable mining strategy.

The company has successfully demonstrated its first battery electric 793 large mining truck as part of plans to transform its Arizona-based Tucson Proving Ground into a sustainable testing and validation hub of the future.

But it also intends to develop green hydrogen production, natural gas and 100% hydrogen reciprocating engine power generation, fuel cell power generation and expanded energy storage systems as part of an ‘alternative energy island’.

The site will also leverage a variety of renewable power sources, including wind, solar and hydrogen, capable of powering the facility and its products as they become electrified.
