Scandlines' new green ferry

News: Scandlines – Digital twin to enable greener ferries

Industry-first digital climate twin to enable greener ferries owned by Danish ferry operator

Scandlines has chosen the Danish climate tech startup ReFlow to develop advanced climate twins of its latest “Zero-emission” ferry design using cutting-edge life cycle assessment (LCA) methodology.

The steel is currently being cut at Cemre Shipyard for the zero-emission vessel contracted by Scandlines for the Puttgarden-Rødby route. Over the following months, ReFlow will build a detailed life-cycle model representing the vessel from its construction to its end of life many years from now. The model will show the environmental impact of the ferry, not only in its use but also from its construction at Cemre Shipyard along with the installed equipment. The digital “climate twin” will make it possible for Scandlines to run simulations on the use of new green technology on the ferry something that is nearly impossible today.

A future-proof investment

Life Cycle Assessment (LCA) is a holistic approach to assessing the environmental impact. It can include all life cycle stages of a vessel and not just the fuel consumption that is common practice in the maritime industry. Incorporating all life cycle stages, the shipowner will get a complete overview of the vessel’s emissions in its entire life, including the fuel consumption. “Our new zero-emission vessel will be electrically powered, so it makes good sense for us to look at the entire life cycle and understand the remaining emissions so they can be improved over time,” states Fini A. Hansen, VP Fleet, Scandlines.

What is a digital twin?

A digital twin is a digital representation of physical products, in this case, a ferry. The digital twin concept became famous in 2010 by NASA, allowing for digital modeling of its space ferries before departure. Today the use of digital twins is widely shared in many industries as it allows for low-cost simulations before installing expensive equipment.

An industry first

The ferry will be environmentally assessed using ISO-backed Life Cycle Assessment methodology – a tool well-known in other industries like automotive and construction but very new to the maritime industry. “We are very excited about the new cooperation and also looking forward to the world premiere of applying life cycle assessment to a complete ferry – it is an industry first to our knowledge,” states Rasmus Elsborg-Jensen, CEO and Founder of ReFlow.

The assessment of the ferry design and its proposed life cycle is no small task. It will run over the next three months and include detailed information on the building processes and chosen equipment aboard.
“It is our ambition to provide Scandlines with a granular understanding of the emissions associated with, not just the fuel use, but also the vessel itself, allowing for future “plug and play” scenarios where new greener technologies can be assessed on the vessel before an investment” states Rasmus Elsborg-Jensen, CEO and Founder of ReFlow

In line with new EU recommendations

The EU highlights the use of Life Cycle Assessment (LCA) as the go-to tool for providing environmental data on products and processes.New EU initiatives like the Green Deal call for more environmental data and product transparency, and Life Cycle Assessment provides exactly that. “Using life cycle assessment, the shipowners can get a more granular understanding of the current environmental profile of a vessel but also, more importantly, understand the future roads towards a greener vessel – a patch that often is linked with partnerships and new technologies,” comments Rasmus Elsborg-Jensen, CEO and Founder of ReFlow

A new digital approach will enable green procurement

ReFlow will, jointly with the traditional Life Cycle Assessment process, incorporate the digital solution that makes it possible for suppliers to make and submit their LCA calculations directly to Scandlines, speeding up the process when selecting new suppliers or evaluating current ones. Several maritime Original Equipment Manufacturers (OEM) are already using the digital platform, which makes it possible to cut the time and cost associated with a life cycle assessment of the products by over 80% compared to traditional manual approaches.
“The digital solution from ReFlow will be a good enabler for our green procurement strategy as it allows our current and future suppliers to provide climate data on their products. Product climate data will allow us to evaluate products and eventually lower the carbon footprint over time,” states Fini A. Hansen, VP Fleet, Scandlines.

Is zero-emission products possible? The challenge behind carbon neutrality

Is zero-emission products possible?
The challenge behind carbon neutrality of products

Have you ever questioned what makes a product zero-emission? If so, we’re here to shed some light on what can often be confusing to those beginning their journey towards calculating their emissions. Throughout this article, we attempt to provide some clarity on the differences between emissions classifications and provide insight into why oftentimes calling your products ‘zero emissions’ can be misleading to stakeholders and consumers.

Understanding Your Emissions-– Scope 1, 2 and 3

Scopes 1 & 2

Greenhouse gas emissions can be understood within the context of three scopes [1], namely scopes one, two, and three. Scope one is what we define as direct emissions. Direct emissions constitute the most well-known and classic example of fuel combustion such as everything that comes out of an exhaust pipe or chimney and enters the atmosphere directly.

Scope two consists of indirect emissions and can be understood through the eyes of company consumption and other actions. An excellent example of this would be energy consumption. If a company utilizes a production line that demands electricity or if they have systems requiring heating or cooling this would fall into what we define as scope two.

Scope 3

Scope one and two have had their fair share of attention and reporting for the many past years. However, recently scope three has overtaken interest within environmental circles, and for good reason.

Scope three can be trickier to understand and assess. Actions that fall into scope three can often possess some of the highest amounts of atmospheric emissions and in some cases, more emissions can be expelled from actions in scope three, than from scope one and two combined. To break it down, scope three is defined as indirect emissions, just like that of scope two. Although, scope three is different in that it encompasses the indirect emissions related to activities throughout a company’s supply chain.

Essentially all emissions related to the upstream and downstream supply chain fall into scope 3 and include, but are not limited to, emissions from raw material extraction, transportation, and even infrastructure. These actions can be difficult to account for, however, they are necessary in order to fully understand emission outputs in their entirety. This is possible with life cycle assessments.

What About Zero-Emission Products?

The only zero-emissions product is a product that reports on all scopes of emissions–including scope 3. ‘Zero-emissions’ products are everywhere. Although, in order to fully claim a product has zero-emissions qualities a Life Cycle Assessment (LCA) must be conducted where the scope one, two, and three emissions are accounted for. Unfortunately, this isn’t common practice for many companies making sustainable product claims.

Irresponsible burden-shifting can mean that different activities with different emissions outputs end up being weighed equally and can therefore result in greenwashing. For this reason, assessing a product from cradle to grave, or from the point of raw material extraction for the product’s creation, all the way up until the complete disposal of the product is instrumental in making honest claims about the product’s entire output of emissions. Governing bodies are currently regulating legislation to lower industry emissions where documentation and reporting for scope 3 are on the horizon. This is pushing many companies into taking these as signs to become fast movers and engage in early reporting.

Is Zero-Emission Achievable?

Selling a product on the basis that it has zero emissions without first calculating the different impacts turns a blind eye to an essential part of holistically assessing the product. The first step toward creating a zero-emissions product is through creating a baseline of everything you know about the product. This is not easy work, but utilizing tools like Life Cycle Assessment (LCA) calculators is easily one of the best places to start.

Tools like life cycle assessments (LCAs) allow you to quantify products with both generic data and company-known data allowing for more in-depth and transparent reporting. Fortunately, extensive digital libraries are also available to make this data even more accessible to everyone.

From here it becomes easier to calculate the scope of emissions, see where hotspots are, and where attention is needed to get closer to a truly sustainable product. It’s safe to say, what would have been deemed impossible just 30 years ago has today become achievable through the use of these impact assessment tools [2].
