Electrified ships and electrifying ports
Electrified ships and electrifying ports
The third IMO GHG Study (2014) estimated that for the period 2007-2012, shipping emitted about 1,000 Mt CO2 per year, equaling approximately 3.1% of the annual global CO2 emissions. A study by CE Delft projects shipping emissions to increase by up to 120% by 2050 if other sectors decarbonize successfully. Vattenfall have identified areas within shipping and the marine segment suitable to start an electrifying journey and decrease fossil fuels-consumption.
Under a business-as-usual scenario and if other sectors of the economy reduce emissions to keep the global temperature increase below 2 degrees Celsius, shipping could represent some 10% of global GHG emissions by 2050. Vattenfall’s vision is to make it possible to live fossil free within one generation and a part of making this a reality is to electrify the transport sector. We see a great opportunity to electrify large parts of the marine sector. This project aims to electrify ships with battery solutions and an electric engine. This in combination with high-capacity chargers at the docks. For larger ships in ports, we aim to offer shoreside power.
We have successfully started our journey by converting the first passenger ferry for 98 pax to a fully electric ferry. By replacing the entire diesel powertrain in boats and ships as well as installing charging solutions dockside, we can significantly reduce carbon dioxide emissions. We install batteries and an electric engine in boats and ships that replaces a diesel engine. As this is a complete solution we intent to install charging infrastructure with high capacity charging on land. Transformers may be needed to be installed to feed the charger to ensure capacity is high enough. This enables the ships to charge rapidly or to charge overnight if the ship is only used by day.
To achieve the climate goals, the transport industry also need to improve logistics and make better use of the opportunities to transport by rail and shipping. At Vattenfall we see that we can make an impact by supplying shoreside power that is directed for larger ships that with today’s technology cannot be completely electrified. To avoid boats in port having their engines running, which they normally need to be able to have their systems running and waiting for takeoff or is awaiting the freight to be on loaded or off loaded. We aim to install high voltage facilities such as transformation stations and connect the large ship directly. The diesel genset is usually connected and running the whole period the ship is in the port, whereas the co2 emissions we be reduced completely with the use of electricity instead.

Swedish green Recovery
The timing of the European Green Deal and the Climate law is excellent. Since around the time of the Paris agreement, there is an impatient willingness to act in the business sector, and we need authorities to catalyse this development.
The Swedish 2030-secretariat was founded to support Sweden’s ambition to decarbonize the transport sector. The Swedish Climate Law set an ambitious sector target for transport – 70 percent reduction of carbon dioxide by 2030. Through 70 partners from industry, municipalities and organisations the 2030-secretariat is supporting this ambitious development, independent of technical solutions or political parties. We are convinced that we need to work in parallel on behaviour, fuels (all low carbon or zero emission fuels) and vehicle technologies. All is needed.
We invited partners to send in proposals that fit well within Green recovery under the Green Deal. We have collected some 30 proposals, mostly in Sweden, in different areas using different technologies. We, the 2030-secretariat, are a Coalition of the willing with a focus on the target year 2030. There are many initiatives brewing in Sweden.
We strongly support initiatives like the Green recovery fund, and we see an increasing interest to take part. In this work we would like to stress the following:
• Allow for a multitude of solutions. We do not know which technology will be decisive, but we do know that many different technologies will be needed
• Changing our behaviour and the use of digital mobility is as important as legislation for vehicles or fuels. The 2020’s is the decade of digitalization, let’s invite digital solutions into the mobility sector
• Avoid having the good alternatives compete. The future is a combo; electricity, hydrogen, biofuels, biogas and some of the new fuels entering the market
• Do not separate fuels in generations or levels of sophistication. We are interested in the greenhouse gas reduction potential of the fuels, not what they are called
We sense a strong willingness to move forward, a season of change that is both needed and welcome. We hope that these initiatives can inspire. If you like an idea – steal it, if you want to participate, contact the person listed by the project. But most importantly, get inspired by what is possible.
The Swedish 2030-secretariat is made up of 70 partners from industry, municipalities and organisations joined in one common goal – supporting Sweden in reaching a 70 percent reduction of CO2 in the Swedish transport sector by 2030. We work in three areas, all equally important: vehicle technology, fuels and electrification and behaviour. All three important areas that need to deliver if we are to reach the climate target for the transport sector. The 2030-secretariat is independent from individual companies and political parties and does not favour any specific technology or solution. The reduction of CO2 is what counts. We are equally inspired by entrepreneurship and innovation as we are with grit, the on-going task of increasing efficiency. We need all to reach the climate targets.
