An offshore vessel-charging solution called Stillstrom is set to be launched by Maersk Supply Service with help from Ørsted to eliminate idle emissions caused by vessels.
Maersk Supply Service’s solution is designed to provide clean offshore electric charging to vessels situated in ports, hubs and offshore energy operations. The buoy is capable of charging an SOV-sized (Service Operations Vessel) battery or a hybrid-electric vessel and can be further adapted and scaled to deliver power to larger boats. When in use, fossil-based fuels are substituted with green electricity, almost eliminating idle emissions.
The first full-scale version of the charging buoy will be installed at an offshore wind farm and demonstrated by Ørsted in the third quarter of 2022. The Stillstrom system will provide an Ørsted Service Operations Vessel with overnight power, supporting the company’s aim of achieving climate-neutral operations in 2025. Ørsted will be responsible for the grid integration of the charging buoy.
To maximize the potential uptake of the clean solution by the offshore wind sector, Ørsted intends to make publicly available any intellectual property generated during the design of the buoy’s integration into the offshore wind asset.
“Stillstrom is part of our commitment to solving the energy challenges of tomorrow,” said Steen Karstensen, CEO, Maersk Supply Service. “By investing in this ocean cleantech space at an early stage, we can help lead the green transition of the maritime industry. Stillstrom has been developed within Maersk Supply Service and the timing is right to create a venture that will be focused on delivering offshore charging solutions.”
“Our vision at Stillstrom is to enable maritime decarbonization, by providing the infrastructure that will allow vessels to charge from clean energy when idle offshore,” commented Sebastian Klasterer Toft, venture program manager, Maersk Supply Service. “The mission is to remove 5,500,000 tons of CO2 within five years of commercial rollout, additionally eliminating particulate matter, NOx and Sox.”
