The project “Renewable Energy Development and Intelligent Implementation in Ports - REDII Ports” focuses on renewable energy from the perspective of a port authority. Launched in 2023 the 15 partners from seven countries inside the North Sea Region and Norway are in the middle of their project activities. The port of Korsør is one of them. Jimmi Jørgensen, port director of the Port of Korsør, explains in a short interview the focus that the port has chosen in the project.

Mr. Jørgensen, how do the goals of Korsør Port align with the REDII Ports project?
The goals of Korsør Port align closely with the REDII Ports project. Both aim to promote the use of renewable energy and intelligent energy utilization in ports. Korsør Port’s short-term plan to implement a shore power facility, supported by the REDII Ports project, will provide a stable and sustainable energy supply, helping achieve climate goals. The port’s experience in noise and air pollution control will contribute to the implementation of green technologies, a key focus of REDII Ports. Long-term, Korsør Port aims to become a leading green port by reducing CO2 emissions and integrating renewable energy sources, aligning with REDII Ports’ goal of modernizing port operations. Additionally, Korsør Port’s involvement in the NON-STOP project, which aims to reduce operational time and pollution through green investments, complements the objectives of REDII Ports, supporting overall sustainability and competitiveness.
Transnational cooperation is crucial for Korsør Port, enabling knowledge sharing and joint development of green solutions. This cooperation has already provided access to new technologies and better methods for reducing environmental impact. 

What is the status of electrification at Korsør Port?
Danish regulations require most ports to be ready to supply shore power by 2030 as part of the ‘Fit for 55’ initiatives. Korsør Port is actively working to meet these requirements by investing in and expanding its shore power facilities and electrical infrastructure. We finished establishing the shore power system in 2021. In summer 2024 we started the battery system implementation process to stabilize power supply. It allows charging during periods of cheap and environmentally friendly electricity and supplying power back to the port during peak demand times. This progress not only supports Korsør Port’s sustainability goals but also enhances its operational efficiency.

What has Korsør Port achieved in electrification and energy storage?
The significant steps of Korsør Port include building up a shore power system and a battery backup solution. We have established shore power facilities and collaborated with other ports like the Port of Moss. The shore power system at Amerikakajen, funded by the EU, is a key part of Korsør Harbor’s green transition. It is expected to reduce CO2 emissions by 470 tons annually by allowing 80% of docked ships to connect to shore power instead of using fuel-driven generators, significantly cutting emissions.
We are also active in the installation of a battery system that functions as a large power bank. We have evaluated the use of solar panels and various battery technologies for energy storage, ultimately selecting lithium-ion batteries for their high energy density, long lifespan, and fast charging capacity.
The interaction between the shore power system and the battery backup solution is essential for Korsør Port’s green transition. The battery system ensures a stable power supply, even during high demand or grid disturbances, maximizing the use of shore power and reducing diesel generator use. This combination significantly cuts CO2 emissions, enhances power security, and provides cost savings through frequency regulation. Investing in these green technologies boosts the port’s competitiveness by appealing to companies seeking partners with a lower carbon footprint.

What kind of challenges does Korsør Port face in meeting regulatory requirements?
Korsør Port is on track to meet the 2030 regulatory requirements, but it faces challenges with noise control, air pollution regulations and the safe use of electricity in port areas. Customer demand variations is also an issue. The demand varies with the season, economic factors and global trade, prompting the port to adjust its services and capacity accordingly. Additionally, there is a significant electricity demand gap during peak periods, which is expected to be mitigated by new battery systems and improved grid connections.

What’s the next step for Korsør Port in the project?
The next steps for Korsør Port in the REDII Ports project include obtaining local authority approval to build the battery system, identifying potential users for the solar panel and battery system, and developing a comprehensive investment plan. During the process, the Life Cycle Analysis will be used to study the environmental impact of the selected technologies throughout their lifecycle, ensuring they are sustainable and environmentally friendly. In 2025 we expect the completion of the REDII Ports project and further plans for green initiatives like solar panels.
