No magic bullet
However, Huckfeldt emphasizes that DAC is no magic bullet. Currently, 4,000 tons of carbon removal is only equivalent to a few thousand flights between London and New York each year. The goal is to scale up to at least one megaton annually by 2030, enabling the removal of an amount of CO2 equivalent to the emissions of a single coal power plant.
“My personal point of view is that there is not really any competition,” he says referring to other companies in the field. “As humanity, we need them all. And luckily there are a lot of new solutions coming up. Even with indirect air capture, I think there are hundreds, close to a thousand companies.”
Most of the emerging companies are in the early stages, focusing on infrastructure projects that require new technology that can’t just be bought off the shelf. Unlike software, it can often take up to 10 years to move from the lab stage to just the pilot stage, says Huckfeldt.
One of the other more advanced players is 1point5, owned by oil major Occidental Petroleum, which is building a large-scale DAC plant in west Texas, due to start operating in 2025 and capture up to 500,000 tons of CO2 a year. Oil producers, including Exxon Mobil, estimate DAC could be a multi-trillion-dollar market by 2050. But their enthusiasm for the technology has attracted criticism that it serves as window-dressing to allow polluters to keep on polluting.
Huckfeldt, who joined Climeworks in 2022 after a varied career that included a stint as the global chief marketing officer of Motorola, says CO2 removal should not be used as an excuse to stall efforts to reduce emissions. “Direct air capture alone is not going to help us. This talk of we are going to overshoot and then basically save ourselves with some magic technologies, whether it’s direct air capture or any other carbon dioxide removal solution. For me, that is completely wrong thinking,” he says.
Removing CO2 from the atmosphere won’t reverse temperature rises quickly due to system inertia and feedback loops, such as increased water vapor and CO2 release from oceans, which drive temperatures higher, he explains.
“So even if we pull CO2 from the atmosphere, that will not actually reduce temperatures for a long time. That’s concerning. Every little percentage, or every little decimal of a degree of temperature, we need to avoid by all means. And we are clearly not changing fast enough.”
Despite the need for policy changes to prioritize renewables, far more money still goes to subsidize the oil and gas industry than to renewable energy, says Huckfeldt. The challenge is that the public is not always prepared to stomach higher energy costs, as shown by the Yellow Vest movement in France where motorists revolted against a hike in fuel prices.
