Direct air capture, a process that removes CO2 directly from the atmosphere, is a more cost-effective way to reduce carbon emissions than using green hydrogen, according to a study by researchers at Harvard University.
The study focuses on the costs associated with the different methods of decarbonization, particularly in industries where emissions are hard to eliminate.
The Harvard study suggests prioritizing direct air capture over green hydrogen for short-term carbon reduction due to its cost efficiency. However, green hydrogen still holds long-term potential as the technology matures and becomes cheaper. Policymakers and industry stakeholders are encouraged to support multiple technologies and adapt strategies as technological and economic landscapes evolve.
The importance of flexible and adaptive policies is emphasized as the world races to meet global climate targets. By investing and supporting a range of technologies, including direct air capture and green hydrogen, the transition to a low-carbon economy can be more effectively achieved.
Direct air capture involves capturing CO2 from air and storing it underground or using it in products. This emerging technology is increasingly viewed as a crucial part of strategies to achieve carbon neutrality. As innovation and scaling efforts continue, costs are anticipated to drop, making it more competitive.
Key barriers for green hydrogen include high production costs and infrastructure needs. While it promises a renewable energy source for hard-to-decarbonize sectors, achieving cost reductions is essential for wider adoption
Effective decarbonization requires supportive policies that promote investment in both established and emerging technologies. Flexibility in policy will be vital, allowing for investment shifts as technologies become more viable and cost-effective.
