Seeking Partners to Co-Develop Direct Ocean Capturing Technology ( DOC) in Desalination Plants

Desired outcome

Major player in the fields of Materials, Chemicals, and Industrial Solutions is seeking partners to implement and investigate an innovative Direct Ocean Capturing (DOC) technology of CO2 within seawater desalination plants. The feasibility of DOC using seawater has already been demonstrated experimentally, showing significant potential, particularly when coupled with desalination processes. By using the brine from desalination as an input for DOC, this approach could unlock substantial economic and operational synergies.

The company aims to collaborate with visionary partners to develop and integrate these processes- initially on small scale (lab) and if successful on a large scale (pilot) - advancing sustainable and efficient solutions for CO2 capture.

The R&D challenges to address include mitigating the impact of by-products in seawater or brine that could interfere with the DOC process , optimizing the process and ensuring extended operating times during experiments, which are critical for scaling up the technology effectively.

Organization from European Union

Research background

Various electrochemical methods for capturing CO2 from seawater have already been explored. Most of these methods employ a pH-swing concept to manipulate the CO2-seawater equilibrium and facilitate the recovery of CO2. Initial electrodialysis experiments conducted with synthetic seawater showed promising results, indicating that the concept of CO2 release was successful, with over 97% CO2 being released. However, a test under real conditions and the improvement of the concept by coupling it to a seawater desalination plant is still pending.

Previously attempted solutions

Utilization of artificial seawater showed promising results. First experiments with real seawater led to problems with fouling, but these could be solved on a laboratory scale with short operating times. The question of how it behaves with long operating times remains open.

Discarded solutions

Other electrochemical approaches, e.g. electrochemical hydrogen looping (EHL).

Criterias for a Successful Partnership

Must Haves:

  • Access to brine from a desalination plant to facilitate the integration and testing of the DOC process.
  • Financial commitment for the development of a joint process (desalination + direct ocean capture)

Nice to Have:

  • Access to the infrastructure of a desalination plant, including existing pumps and pipes, to streamline the setup and operational phases.

Other Requirements:

  • A consistent supply of brine to serve as an input stream for the DOC process.
  • Depending on the cell type used, partners must ensure the availability of a safety enclosure to manage the safe handling of hydrogen and oxygen by-products formed during the process.
  • Compliance with relevant legal, environmental, cost, and operational standards.

Desired Business Relationship

The desired business relationship for this initiative is a joint development partnership, fostering collaboration to innovate and jointly develop the DOC technology together as an integral part of a desalination plant..
