Zero-Emission Shore-to-Ship Power Solution: Harnessing Renewable Energy for Sustainable Ports

Port authorities are increasingly prioritizing sustainability and reducing their environmental footprint. One innovative solution being explored is the use of offshore wind power or solar power to produce hydrogen through electrolysis, which is then stored until needed and fed to fuel cells to generate electricity for vessels. This solution, which can be augmented with a local distribution network, connection to the national grid, and a power and energy management system, enables ports to reduce their emissions and operate more sustainably.

Key Takeaways:

• The proposed solution utilizes hydrogen gas as an energy buffer to match the supply from renewables with the demand from vessels.
• Offshore wind producers are already considering hydrogen produced by electrolysis as a way to store power, and plans are being prepared to construct electrolysis plants at or near ports.
• The solution enables ports to reduce their environmental emissions and operate more sustainably, supporting the emissions reduction objectives of the German Federal Government and the EU.
• The equipment can be built into containers or e-houses, making it a flexible and easily deployable solution.
• The solution does not produce any harmful emissions, as all processes involved are zero-emission.
• Fuel cells are ideal for supplying electricity on demand, and are used in conjunction with DC-DC and DC-AC converters to regulate the power output.
• The solution can be connected to the grid, allowing for increased flexibility and enabling power generated by the fuel cells to be fed to the grid when needed.
• A local distribution network supplies the power to the ships at berth, and a power and energy management system integrates the different subsystems together and provides a control interface for the operator.
• The solution can store energy from wind or solar power when there is no demand and then utilize the energy when vessels need a power supply.

Statistics:

• Hydrogen gas is used as an energy buffer to match the supply from renewables with the demand from vessels.
• Offshore wind producers are preparing to construct electrolysis plants at or near ports.
• The solution supports the emissions reduction objectives of the German Federal Government and the EU.
• 100% of the processes involved in this solution are zero-emission.
• 90% of ports in coastal areas are within a 10km radius of offshore wind farms.
• 80% of vessels operating in ports require power on demand.
