About us

ESTECH A/S was established in 2018 and is an engineering and development company that develops sustainable technologies in collaboration with PureteQ. Our vision is to create and deliver cost-effective technologies that combat the impact of human induced climate change by reducing greenhouse gass emissions and transforming harmful compounds into valuable products.

Dictated by the laws of nature

The ESTECH culture

Creating the right company culture is essential to achieving our goals. We encourage bold ideas and dare to make mistakes. We strive to push boundaries and keep things simple, while recognising that we are bound by the laws of nature.

For us, cutting-edge innovation is not just about creating new, ground-breaking technologies – it is about developing reliable technologies that are more cost-effective than competing solutions on the market.



The energy efficient technology combining carbon capture and production of hydrogen consumes less energy than other plant designs that typically focus on either CO2 capture or hydrogen production. We have demonstrated that a high percentage of the green energy consumed by the ESTECH pilot plant is attributed to the production of hydrogen. It therefore has the potential to become the most energy efficient CCS technology on the market for small and medium sized industries with no available thermal energy source. We call the technology CAPPOW short for Carbon Capture and Power-toX.


Patented solution

Our patented technology that combines carbon capture and parallel production of hydrogen is unique as it merges two operations in one process. The ESTECH technology provides cost-efficient CO2 capture and optimal Power-to-X integration between CO2 capture and hydrogen production – all based on green electrical power with no thermal heat requirement.


A part of PureteQ Group

ESTECH and PureteQ A/S are subsidiary companies of PureteQ Group with administration, design, research, and development, including testing and production facilities, in Svendborg, Denmark. By relying on PureteQ’s patented exhaust gas purification technology, based on hydrodynamic fluid distribution, we have been able to accelerate our product development process. We will continue collaborating with our sister company PureteQ on building and designing our next plant, which is expected to demonstrate the technology’s scalability and increase existing capacity to near-industrial size. The hydrodynamic fluid distribution ensures optimal conditions for the gas/fluid reaction, resulting in a smaller reaction chamber/scrubber. PureteQ’s expertise is not limited to the scrubber tower but also the process control and after-sales service and spare part mangement.
