Synopsis:

A groundbreaking seaweed farm off Norway's Trøndelag coast aims to combat climate change by testing large-scale kelp cultivation as a cost-effective carbon removal solution. The three-year pilot project, JIP Seaweed Carbon Solutions, backed by a NOK 50 million budget, involves SINTEF, DNV, Equinor, Aker BP, Wintershall Dea, and Ocean Rainforest. The project explores seaweed's potential to capture significant carbon amounts, aiming to develop a verified methodology for ocean-based carbon removal. Researchers anticipate the farm's first harvest in 2024, targeting a seaweed yield of approximately 150 metric tons.

In a bold initiative to address climate change, a pioneering seaweed farm has taken root off the coast of Trøndelag, Norway. Launched last year, the project received its cultivation license this summer and deployed the first seaweed seedlings in November. This offshore endeavor seeks to evaluate the viability of large-scale kelp cultivation as a sustainable and cost-effective solution for removing carbon from the atmosphere.

As the urgency to find effective carbon capture and storage solutions grows, researchers and industry leaders have come together for the three-year pilot project, JIP Seaweed Carbon Solutions. With a budget of NOK 50 million, the project involves key players like SINTEF, DNV, Equinor, Aker BP, Wintershall Dea, and Ocean Rainforest. The focus is on investigating whether kelp can contribute significantly to ocean-based carbon removal, potentially reducing greenhouse gas emissions and opening new industries and job opportunities for Norway.

Head of Sustainability Development and Climate at DNV, Ellen Skarsgård, emphasizes the project's significance in developing a verified methodology for carbon capture and storage with seaweed. While various initiatives aim to reduce emissions, this project stands out for its dedication to researching methods for removing already emitted carbon dioxide (CO₂) from the atmosphere and storing it effectively.

Senior Researcher Jorunn Skjermo at SINTEF explains the project's dual approach: exploring chemical processes to transform seaweed into biochar, suitable for soil improvement, and developing a robust methodology for carbon removal.

The licensed aquaculture site, spanning 200 hectares off the coast of Mid-Norway, is now poised to receive the first seaweed seedlings cultivated in laboratories. This multifunctional demonstration site allows researchers to test innovative aquaculture technologies, monitor biomass and environmental impacts, optimize cultivation strategies, and develop technology for biomass harvesting.

The proof-of-concept phase is crucial, aiming to demonstrate cultivation technologies and storage solutions. The first harvest, anticipated in the summer of 2024, is projected to yield approximately 150 metric tons of seaweed. While this may seem modest, researchers highlight the importance of validating the concept before scaling up the technology.

Skjermo underscores the urgency of leveraging seaweed as a vital resource for managing CO₂, emphasizing the need to initiate transformative efforts promptly.

Conclusion:

Norway's venture into large-scale seaweed cultivation for carbon capture signals a significant step toward sustainable solutions. The ongoing pilot project not only explores the potential of seaweed to capture carbon but also lays the groundwork for a verified methodology crucial for achieving climate goals. As the seaweed farm off the Norwegian coast becomes a beacon of innovation, it holds the promise of not only reducing emissions but also providing a blueprint for global carbon removal efforts.
