Wärtsilä's Commitment to Decarbonization: Navigating the Future of Marine and Energy Industries

HYDROGENCARBON CAPTURE

Wärtsilä stands at the forefront of a pivotal transition in two of the most significant contributors to global CO2 emissions: the marine and energy sectors. Currently, 60% of its business pertains to marine activities, with the remaining 40% focused on energy.

Together, these industries are estimated to account for approximately 35% of global emissions, a stark reminder of the urgent need for decarbonization. Although experts suggest that achieving the Paris Agreement's 1.5-degree target may be beyond reach, advancements in technology provide a beacon of hope.

The good news is that much of the requisite technology for a decarbonized future already exists—from low and zero carbon fuels to emission abatement solutions like carbon capture. Wärtsilä's commitment to supporting customers through this transition is unwavering, focusing on environmentally sustainable and financially viable solutions. With vessels built today expected to operate for decades, Wärtsilä is actively working with shipowners to design and retrofit ships that not only comply with evolving regulations but remain competitive in a rapidly changing energy landscape.

Last year marked a significant milestone, with approximately 2,000 large new vessels launched. These ships, expected to serve for around 30 years, must be equipped to handle the complexities of a decarbonization transition.

This is where Wärtsilä's fuel flexibility strategy becomes crucial. The company is already marketing technologies that support multiple fuel types, allowing customers to begin their journey with one fuel and transition to more sustainable alternatives as they become available.

Cost remains a significant barrier, as new fuels may be two to four times more expensive than traditional fossil fuels. To address this, Wärtsilä advocates for carbon pricing mechanisms that could help level the economic playing field. As the push for decarbonization accelerates, Wärtsilä prioritizes various technologies to maximize both immediate and long-term impact.

Among the key areas of focus are new fuels, including biofuels and green methanol, which are considered carbon neutral due to their recycling of carbon atoms. Wärtsilä is ready to deploy technology compatible with these fuels.

Additionally, the company is investing in zero-carbon fuels like ammonia and hydrogen, having recently launched its first ammonia engine and a hydrogen power plant concept. Hybrid solutions, which combine batteries with combustion engines, are also part of Wärtsilä's innovative approach to a sustainable future.

Navigating the complex regulatory environments of the marine and energy sectors presents its challenges. The marine industry is regulated by the International Maritime Organization (IMO), which has a strong decarbonization agenda.

In contrast, the energy sector is governed by national policies, which vary significantly across regions. The long-term vision for a cleaner future hinges on expanding renewable energy sources, such as wind and solar, while addressing their inherent intermittency.

Wärtsilä's strategy adapts to regional differences, engaging in markets like the UK, Texas, and Australia, where renewable energy is rapidly gaining traction. In Brazil, the company is pioneering the development of the first ethanol engine for power plants, while in Norway, it has launched an ammonia engine. This region-specific approach underscores Wärtsilä's commitment to fostering sustainable practices tailored to local needs.

As global discussions on carbon pricing gain momentum, the IMO's recent proposal to implement a carbon pricing framework could reshape the shipping industry's economics. If adopted, it would introduce unprecedented regulations, compelling shipowners to meet carbon intensity targets or face financial penalties. This potential shift could significantly impact operating costs, pushing the industry toward greener technologies.

In the U.S., Wärtsilä is strategically positioning itself to navigate challenges posed by tariffs, inflation, and geopolitical tensions. While most ships are built and operated outside the U.S., the company recognizes the importance of affordable energy in the face of rising costs. As energy generation expands, collaboration across the value chain will be essential to accelerate the integration of renewables.

Wärtsilä's proactive stance in embracing innovation and sustainability reflects a clear understanding of the complexities that lie ahead. By sending a strong signal to the ecosystem, the company aims to drive investment and foster cooperation, ensuring a resilient and sustainable future for both the marine and energy sectors.
