The Maritime Battery Forum has welcomed Stillstrom, an innovative company owned by the A.P. Moller-Maersk Group, dedicated to delivering offshore power and charging solutions, as its newest member.
Stillstrom’s business is intended to transform offshore power supply by enabling vessels to connect to clean electricity while stationary at sea or in port. The company’s mission is to eliminate offshore vessel emissions and support the maritime industry’s decarbonisation through offshore charging technology.
By providing offshore charging solutions for hybrid and electric service operation vessels (SOVs), Stillstrom plays a role in enabling emissions-free operation at sea. The company’s innovative infrastructure establishes zero emission anchorage zones—transformative spaces where vessels traditionally reliant on fossil fuels can now switch to clean electrical power, drastically reducing emissions such as CO₂, NOₓ, and SOₓ.
Stillstrom began in 2019 as a business innovation initiative within Maersk Supply Service. Its mission was to tackle offshore emissions through electrification. Early support from the Danish Maritime Fund and a pivotal grant from the Danish Energy Agency’s EUDP programme helped fuel the development of Stillstrom’s core technologies. By 2020, the company had introduced its first offshore charging concepts, and in 2021, a collaboration with offshore wind compay Ørsted propelled Stillstrom into a key role in offshore clean power infrastructure.
Today, Stillstrom operates as an independent company under the A.P. Moller-Maersk Group, with a dedicated focus on scaling and deploying offshore charging systems that align with the broader global push toward green energy.
Kristian Borum Jørgensen, CEO Stillstrom by Maersk, said: “We are thrilled to join the Maritime Battery Forum and collaborate with industry leaders to drive the green transition in the maritime sector. At Stillstrom, we are committed to delivering innovative offshore power solutions that reduce emissions and create a cleaner future for coming generations.”
Stillstrom is currently involved in a series of collaborative projects aimed at integrating offshore charging into both vessel and wind farm design. This end-to-end approach ensures that battery-powered operations are considered from the earliest planning stages of offshore energy infrastructure.
Highlights of Stillstrom’s recent and ongoing initiatives include: ScottishPower renewables collaboration; feasibility studies for zero emission anchorage zones; harbour trials and dynamic positioning (DP) tests; virtual reality (VR) training; and industry collaboration on eSOV integration.
Through its membership in the Maritime Battery Forum, Stillstrom aims to strengthen its global network of innovators, regulators, and industry leaders working toward maritime electrification. With MBF’s global community, Stillstrom can connect with pioneers in maritime battery development, collaborate on projects, research initiatives and continue to promote the adoption of clean energy technologies in the maritime industry.
