Arca expands to three continents to advance carbon mineralization

Arca of Vancouver has announced that it is working with producers of nickel, a critical metal for the clean energy transition, to advance carbon dioxide removal at mine sites on three continents.

The company works globally with nickel mine developers and operators to capture and permanently store CO2 in mine tailings using Arca’s technology.

Arca is developing and commercializing a portfolio of technologies that help mining companies measure, maximize, and monetize the carbon sequestration potential of their mining by-products.

The company’s patent-pending mineral activation technology (picture above) uses high-intensity bursts of energy to transform and disrupt the mineral lattice structure of magnesium rich minerals, increasing both the rate and capacity for CO2 capture and permanent storage. With material from its mining company partners, the company says it has achieved never-before-seen rates of air capture and capacity for CO2 storage, operating at atmospheric air temperature and pressure.

Arca is backed by Lowercarbon Capital and the Grantham Foundation, the leading climate investors in the rapidly emerging carbon dioxide removals industry. “With Arca, mining companies can turn tailings liabilities into assets by unlocking gigaton-scale carbon removal,” said Ryan Orbuch, Partner at Lowercarbon Capital.

Arca can work with legacy (closed) mines, junior (under development) mining companies, as well as existing mine operations of any size, and is currently working with mining companies in key mining jurisdictions such as Canada, Australia, the U.S., and Southeast Asia.

Most recently, Arca announced that it is working with the global mining major Vale, and the Australia-based juniors Poseidon Nickel, Nickel Search, and Blackstone Minerals.

Arca is also working with Talon Metals which, in a joint venture with Rio Tinto, is developing the U.S.’s only high-grade nickel resource for the domestic battery supply chain.

Arca has been recognized with a US $1M XPRIZE Milestone Award for Carbon Removal, a Foresight50 Award as one of Canada’s most investable cleantech ventures, and an SDTC Seed Fund grant.

Arca produces and sells carbon dioxide removal services to climate leaders with contracts previously announced with Shopify and Frontier which was founded by Stripe, Alphabet, Shopify, Meta, McKinsey and others. The company is also supported by Canada’s National Research Council.
