Google-backed consortium to scale up ocean and rock carbon removal

An executive revealed that a coalition of Google, Stripe, and Shopify would spend $1.7m to purchase carbon removal credits for three early-stage firms. This will help the tech giants scale up the nascent market.

To meet climate goals by the mid-century, the world will need to remove between 5 and 10 billion tonnes of carbon dioxide per year from the atmosphere. However, most of the technologies available today are of a small scale.

Frontier is a coalition that includes Meta, H&M Group JPMorgan Chase, Salesforce and others.

The group will spend $1.7million to purchase credits from Karbonetiq in the U.S., Limenet, a company based in Italy, and pHathom, a Canadian firm.

Hannah Bebbington is the head of Frontier's deployment. She said that by contracting early to purchase, the companies are better equipped to hire, raise funds and get technologies up and running.

She said, "It allows businesses to demonstrate their commercial viability."

Frontier's fifth commitment is to support these early-stage firms that aim to store emissions in the ocean, rocks, and industrial waste.

Frontier, which began operations in 2022, plans to invest $1 billion between 2022- 2030 in carbon credits. It has already committed to $600 million. Some of that was spent on pre-purchases, and most of it on off-take agreements. It agreed last week to pay $41million for 116,000 tonnes of waste biomass from Arbor.

In oceans, it is important to increase the alkalinity to help reduce carbon dioxide emissions. This is done by adding "quicklime", which is made of limestone.

Mineralisation technologies are a way to accelerate the natural process of rocks and industrial waste absorbing carbon dioxide. For example, by crushing the material, you can create a greater surface area.

Bebbington stated that both technologies have the potential to make a difference because they can be scaled up quickly and inexpensively.
