In the future, container ships will be able to emit fewer pollutants while they are berthed in ports – a pilot project in has now tested how the air quality can be improved. The electricity for the ships’ on-board operation was generated by a new, mobile generator that runs on liquefied natural gas (LNG).
According to the industry, liquefied natural gas reduces sulfur, nitrogen oxide and fine dust emissions on ships to almost zero and carbon dioxide (CO2) emissions by around 20 percent. If the generator generates the electricity, the auxiliary diesel generator sets in the ships can be switched off while they are in port.
The technology company Becker Marine Systems initially wants to supply the shipping company’s container ships with it. The ships with space for 15,000 or 20,000 standard containers (TEU) dock at the Burchardkai terminal of Hamburger Hafen und AG (HHLA). But there is already interest from abroad in the new technology, it said.
According to Becker Marine Systems, the systems used to generate electricity for on-board operation are so-called Powerpacs. These are mobile 1.5 megawatt power plants with a gas-powered generator and an LNG tank, which are hoisted from the quay using a container bridge to a parking space at the stern. The Federal Ministry of Transport is funding the development of the technology with a sum of millions.
