DNV Clears Aker Offshore Carbon Capture Tech
The Just Catch Offshore, a modularized carbon capture facility for offshore installations, has been successfully qualified by DNV.

The Just Catch Offshore, a modularized carbon capture facility for offshore installations, has been successfully qualified by DNV, the global independent energy expert and assurance provider.

It is now ready to be deployed in offshore oil and gas fields where Aker Carbon Capture's proprietary solution can significantly reduce emissions from offshore power generation.

"DNV's recently published Energy Transition Outlook report reveals that Carbon Capture and Storage is indispensable for global decarbonization efforts, across multiple industry sectors. We are pleased to provide validation of the technology in a frontier application area – power generation in the offshore sector. DNV has validated that Aker Carbon Capture's modular technology Just Catch Offshore can capture CO2 from flue gas stemming from turbines on floating offshore installations," said Jørg Aarnes, Global Lead for hydrogen and CCS at DNV.

Oil and gas production is a significant source of CO2 emissions. In Norway, the industry accounted for 25 percent of the country's total emissions in 2021, according to Statistics Norway. As operators are looking for ways to reduce their own emissions, offshore CCS is emerging as a competitive alternative.

"This successful qualification further strengthens the trust from the global offshore market in our Just Catch Offshore offering," said Aker Carbon Capture's CEO Valborg Lundegaard. "Given its extensive experience in qualification procedures, DNV's statement offers strong value to both our partners and us. CCS will be an important tool to help decarbonize the oil & gas industry, reducing emissions from gas turbines. CCS can also offer the industry an energy- and cost-efficient way of utilizing the available energy resources by avoiding large electric transmission loss across the onshore grid."

The offshore facility with Aker Carbon Capture's proprietary technology is considered fit for harsh weather conditions with severe motions, according to the qualification. The Just Catch Offshore solution is now ready for a traditional field development project path, including a FEED phase, EPC delivery and operational support. 

Since 2018, Aker Carbon Capture has been working on the development of the Just Catch Offshore. The product has been optimized and matured through concept studies with E&P and FPSO operators in the oil and gas industry globally. The modularized solution can fit into any type of application where gas turbines are present, bottom fixed as well as floating production facilities. 

Aker Carbon Capture's standardized Just Catch Offshore offering is based on a modularized design with two standard units of 120 and 180 kTPA as building blocks. The units are typically configured and installed into one module. By combining modules, the capacity can be increased and adjusted in accordance with the specific requirements, providing a significant flexibility towards capture capacity and power demand. 

"The CCS module will typically be prefabricated and be made mechanical complete before lifted onboard onto the host facility at the integration yard for further hook-up to the gas turbine stacks, with a delivery time of 20-24 months. The CCS plant capacity is fitted to an offshore facility with several turbines in operation. Various gas turbine models are now considered compatible with our capture units," said Jim Stian Olsen, Chief Technology Officer at Aker Carbon Capture.

Currently, Aker Carbon Capture is delivering a Just Catch EPC project for Twence's waste-to-energy facility in Hengelo, the Netherlands. 

"The proven Just Catch onshore plant model has been an important starting point for the development of our Just Catch Offshore solution. Nonetheless, as the offshore environment and the design criteria are different from our land-based applications, we found it necessary to undertake a qualification program for our Just Catch Offshore unit. The need to include other materials, as well as the necessity to handle and maintain the plant performance during severe motions have been important criteria for further design adjustments," said Jim Stian Olsen.
