Purem by Eberspaecher develops new direct air capture technology
- Removing CO2 from the atmosphere
- Transfer of expertise from exhaust technology
- Scalable technology with a focus on cost-effectiveness
Purem by Eberspaecher has unveiled its latest direct air capture (DAC) solution.
Negative emissions for climate protection. The exhaust and acoustic specialist offers a wide portfolio of components that help to reduce emissions in the mobility sector. Purem by Eberspaecher takes things a step further with its DAC technology, presenting a system that removes CO2 from the atmosphere and generates negative emissions. Ambient air is passed through a reactor. This has a solid sorption medium to which carbon dioxide molecules adhere. Once these are saturated, the heating process begins and the carbon dioxide is released and collected in a gaseous state. It can either be stored (carbon capture storage) or re used as a raw material (carbon capture utilization). A self-contained cycle that is climate-neutral is created. “Numerous sectors will not be able to sufficiently reduce their CO2 emissions along their own production chain. Actively removing carbon dioxide directly from the atmosphere can play a key role in improving their carbon footprint,” explains Avinash Mutharja, Executive Vice President of Technology & Innovation, Purem by Eberspaecher. “Our DAC technology is an innovative approach to tackling this task. It is efficient, scalable, and adaptable to a wide range of applications.”
Storage and use of carbon dioxide. The DAC approach from Purem by Eberspächer is based on many years of expertise in catalysis. Following intensive research, the reactor now features an efficient process for storing and releasing carbon dioxide in under an hour, while also enabling the raw material to be purified to a particularly high degree. This means that the captured CO2 can be used for a variety of purposes, including the production of synthetic fuels (e-fuels), plastics and fertilizers. If it is to be used further, carbon dioxide must be significantly purer than is required for long-term storage purposes – the solution developed enables both.
Location-independent and flexible technology. The system requires merely electricity to power the CO2 capture process; no other fuels or waste heat are necessary. This means that Purem by Eberspaecher DAC technology can be used anywhere, including remote areas where renewable energy can be produced cost-effectively, even without a connection to the power grid. This can be achieved through methods such as wind power or solar generation. A load-flexible operating strategy makes this possible, whereby the system adapts to weather conditions and electricity availability while reducing the need for intermediate energy storage.
Carefully designed concept. The reactor is made of corrosion-, acid- and heat-resistant materials. In addition to robustness, Purem by Eberspaecher is focused on developing technology based on a scalable manufacturing concept that draws on the company’s own industrialization expertise. The aim is to continuously reduce the cost of separating one ton of CO₂ and thus make a viable economic contribution to climate protection.
