![]() Once trapped, a change in voltage releases the CO₂. The Massachusetts Institute of Technology spinoff has developed a special type of plastic that can selectively pull out CO₂ from a mix of gas-in air or exhaust-when charged with electricity. Verdox has a different approach that it claims to be more efficient and therefore cheaper. Despite decades of work, the cost of this conventional approach remains too prohibitive to scale up to capture the hundreds of millions of tons of CO₂ annually needed to put the world on a path to net zero. All these steps take a huge amount of energy, which contributes to making the technology expensive. The CO₂ can then be compressed and injected deep underground for permanent storage. Once the liquid captures the gas, it’s heated to a temperature that allows the the CO₂ to be released. The majority of current technologies use liquid solvents that attract CO₂ like a magnet pulls iron filings. Direct air capture technology offers more hope that the offset will do away with the promised amount of greenhouse gas for thousands of years.Ĭarbon capture works by separating CO₂ from the air or exhaust gases from factory smokestacks. Nature-based offsets such as forests have become a wildfire risk-ironically due, in part, to climate change-and could release any CO₂ they might have stored. ![]() But Chief Executive Officer Brian Baynes says that a recent breakthrough with the key material used to trap the greenhouse gas has given investors confidence to invest such a large sum at an early stage in the startup’s development.Īs the world gets serious about reaching net-zero emissions within decades, there’s growing interest in technologies that can permanently sequester CO₂ already in the atmosphere. A Massachusetts-based startup that captures carbon dioxide directly from the air has raised US$80 million from investors, including Bill Gates-led Breakthrough Energy Ventures.įounded in 2019, Verdox Inc.’s technology is still only operable at lab scale.
