Shore Power and Cold Ironing for Ships

Detailed overview of innovation with sample startups and prominent university research


What it is

Shore power, or cold ironing, refers to the provision of electricity from shore-based power grids to ships at berth, enabling them to switch off their auxiliary engines, which are typically powered by diesel fuel. This process eliminates emissions from the ship’s engines while docked, improving air quality and reducing noise pollution in port areas.

Impact on climate action

Shore Power and Cold Ironing drastically reduce emissions from maritime vessels by enabling them to connect to onshore power sources while docked, eliminating the need for onboard generators. This innovation significantly reduces greenhouse gas emissions and air pollution, fostering a cleaner and more sustainable marine transportation sector, crucial for climate action.

Underlying
Technology

  • Electrical Infrastructure: Shore power systems require specialized electrical infrastructure at ports, including high-voltage connections, transformers, and switchgear to supply power to vessels.
  • Compatibility Standards: Standardized connectors and voltage levels are crucial to ensure compatibility between shore-based power systems and ships’ electrical systems.
  • Frequency Conversion: Differences in electrical frequency between the shore grid and ship systems often require frequency converters to ensure compatibility.
  • Grid Management: Integrating shore power into the local electricity grid requires careful planning and grid management to ensure stable and reliable power supply.
