Researchers have developed a device that captures carbon dioxide by pumping it across a battery, requiring significantly less energy than existing capture systems.
The breakthrough leverages battery technology to make carbon capture more efficient. Instead of using traditional chemical or physical separation methods that demand substantial energy input, the new device exploits electrochemical processes to extract CO2 from air or industrial sources.
The battery-based approach works by moving carbon dioxide across a charged membrane, where electrochemical reactions separate and concentrate the gas. This method reduces the energy requirements compared to current carbon capture solutions, making the technology more economically viable for large-scale deployment.
Carbon capture remains critical for climate goals, as it can remove emissions directly from the atmosphere or prevent release from industrial facilities. The improved efficiency of this device could help make carbon capture more accessible and cost-effective for commercial use.
The research represents progress toward practical carbon removal technologies, though widespread implementation would still require further development and testing at scale.
NASA's PRIMA mission will construct a major space telescope using leftover components from the James Webb Space Telescope, aiming to complete the project faster and cheaper than traditional builds.
An $11 million XPRIZE competition demonstrated that detecting wildfires within 10 minutes is achievable, but actually suppressing them remains a far greater challenge.
ArXiv, the preprint repository used by millions of researchers globally, has received multiyear financial commitments that will support its operations as an independent nonprofit organization.
The European-Japanese BepiColombo spacecraft is approaching Mercury following an eight-year voyage through space. The mission will investigate the planet's magnetic field and internal structure.
