What does the company see as the most promising solutions for the future, and what are the main obstacles to a green shift? Roger Holm, President of Marine Solutions in Wärtsilä, shares some perspectives on the way forward for more climate-neutral shipping.

“The next few years will be crucial for restructuring shipping, and it is more urgent than ever to cut greenhouse gas emissions. In the years to come, we will see a gradual transition to motor solutions that are more flexible, with the possibility of combining several energy carriers,” says Holm.

“In the future, we will have ships running on green ammonia and green methanol, and there will be a need to use a mixture of fuels to meet profitability and cost requirements. LNG will continue to be important for various industries in a transitional phase. We will also see a rapid development in electrification and hybrid solutions, and more emphasis will be placed on energy optimization.”

We will need to focus on innovation and on new green solutions. But to succeed, the right incentives must be in place.

– What are the most important obstacles to increasing the pace of the green shift? 

“We will need to focus on innovation and on new green solutions. But to succeed, the right incentives must be in place. We must ensure that the transition we are facing is possible to implement in terms of cost. It will require good regulatory and framework conditions and getting the necessary carbon taxes in place. If the industry is to develop new solutions, we must feel secure that it pays to invest and that there are schemes that will contribute to profitability and necessary scaling.”

– Decarbonisation and digitization are two main drivers in the maritime industry. How can digitization contribute to greener shipping? 

“Digitization can provide greater optimization of the fleet, which in turn means using less fuel, emitting a smaller amount of greenhouse gases, and operating more cost-effectively. Concrete examples of this are the optimization of sailing routes and the use of the ‘just in time’ principle, which helps to minimize fuel consumption and ensure the least possible time in port.

The massive transformation of shipping we are facing today cannot be driven by individual players. It is only when we work together that we can accelerate green development.

– Wärtsilä is active in Norway and has a number of Norwegian partners. How do you see the further development of this Finnish-Norwegian cooperation? 

“The massive transformation of shipping we are facing today cannot be driven by individual players. It is only when we work together that we can accelerate green development. Wärtsilä has a number of activities in Norway, both proprietary and in collaboration with Norwegian players. We see impressive ambitions for the green shift from the Norwegian side. This means that we see Norway as an ideal ‘hub’ to be able to contribute substantially to the decarbonisation of shipping.
