VISIONS FOR THE FUTURE
by PureteQ
Different opportunities will be explored both in ESTECH and PureteQ separately, and in collaboration
Biogas Upgrade

The call for upgrading biogas can, in the short run, turn out to be applicable for the ESTECH CAPPOW technology.
In brief, biogas upgrade is a matter of omitting a great deal of the naturally occurring CO2, in biogas. This is a regulatory requirement before injecting biogas on the natural gas grid.
The CAPPOW technology can reduce both the amount of CO2 and produce the hydrogen necessary for further reduction of CO2 in biogas. In 2023 tests to demonstrate this will be completed and presented to interested biogas plants.
In Denmark alone, more than 120 biogas plants have the potential to use the technology for biogas upgrade. Abroad there are now thousands of plants producing biogas.
Solevent Based Carbon Capture
Carbon capture and production of green hydrogen in one and the same process require access to green electricity in sufficient quantities. Green or clean electtricity may not be available for production of hydrogen for years to come, regardsless of political ambitions. On those grounds, we will explore the opportunities for employing the more common technology for carbon capture based on amines and other solvents, parralel to the CAPPOW technology.
Onboard Carbon Capture
The main barrier for Onboard Carbon Capture (OCC) is energy supply. In cooperation with ESTECH, a marine adaptable carbon capture technology is being developed. We believe that a combination of high temperature heat pumps combined with an activator in the solvent may be the answer to reducing the OCC conditioned energy. A feasibility study has been performed indicating that this OCC technology is competitive, especially regarding energy consumption.
Further, this could prove effective as to decreasing sensitivity of solvents towards particles, SOx and NOx.
A partner for the onboard testing of this OCC technolgoy will be identified during 2023.
Future Scrubber Projects
PureteQ’s future project business will partly be based on sulfur scrubber projects, but with focus on making our scrubbers future-proof with OCC ready installations, as well as adding PureteQ’s existing digital control system and other optimized equipment.
