London start-up Mission Zero Technologies (MZT) is working with Montreal-based Deep Sky, the world's first tech-agnostic carbon removal project developer, to validate its electrochemical direct air capture (DAC) technology.

MZT’s compact modular DAC system has been delivered and installed at Deep Sky’s carbon removal innovation and commercialisation centre, Deep Sky Labs, in Alberta, Canada.

Powered by renewable solar energy, Deep Sky will use MZT’s containerised system to recover CO2 from the atmosphere for permanent storage underground.

The aim is to initially demonstrate carbon removal on a small scale using MZT’s technology through capturing up to 250 tonnes of CO₂ from the atmosphere each year.

Having validated the technology, the DAC system will then be scaled into a commercial facility that aims to remove up to one million tonnes of CO2 annually.

MZT’s DAC technology works by removing CO₂ from the air using only water, a catalyst and renewable electricity. Fans pull in air from...
