Carbon capture specialist Climeworks is strengthening its research into direct air capture (DAC) with a new high-throughput adsorption testing unit from Netherlands-based Avantium R&D Solutions.

The system will help Climeworks test and develop more efficient materials for CO2 removal, supporting the company’s efforts to scale up DAC technology and reduce costs.

The unit, designed to refine CO2 adsorption processes, has already shown efficiency gains.

Avantium says that the technology uses 25 times less sample material and gas, cutting costs and making testing more efficient. It also ensures all materials are tested under the same conditions, improving accuracy and helping Climeworks to refine CO2 capture technology faster.
