landström

Landstrøm, a term derived from the Norwegian words "land" (land) and "strøm" (current or power), refers to the provision of electrical power from shore to ships at berth in ports. This practice is also known as shore-to-ship power or cold ironing. The primary purpose of landstrøm is to reduce emissions from ships by allowing them to turn off their auxiliary engines and connect to the local electrical grid while docked.

The implementation of landstrøm involves the installation of shore-side power facilities and the necessary infrastructure on both the port and the vessel. This includes the provision of power cables, transformers, and other electrical equipment. Ships equipped for landstrøm have onboard systems that allow them to switch from their own power generation to shore power seamlessly.

The benefits of landstrøm are significant, particularly in terms of environmental impact. By using shore power, ships can eliminate the emissions associated with idling engines, including sulfur oxides, nitrogen oxides, and particulate matter. This is especially important in urban areas where ports are located near residential and commercial districts. Additionally, landstrøm can reduce noise pollution, as ships' auxiliary engines are notoriously loud.

The adoption of landstrøm has been growing globally, driven by stricter environmental regulations and increasing awareness of the need for sustainable practices in the maritime industry. Several ports around the world, particularly in Europe and North America, have already implemented shore-to-ship power systems. However, challenges such as high initial costs, technical complexities, and the need for international standards and regulations remain obstacles to widespread adoption.

In summary, landstrøm is a crucial innovation in the maritime industry aimed at reducing emissions and improving air quality in port cities. As technology advances and environmental regulations become more stringent, the use of shore-to-ship power is expected to become more prevalent.
