Sustainable Innovation: Redefining Environmental Standards in the Maritime Industry, Wärtsilä Launches Commercial Ammonia Engine, An Eco-Efficient Alternative for Bulk Carriers

According to The Maritime Executive, Wärtsilä is leading the revolution in sustainable maritime transport with the launch of the first engine powered by dual fuel, a 4-stroke ammonia commercial engine. This promising innovation is about to transform the industry, offering an eco-efficient alternative for bulk carriers.

The ammonia solution, based on the proven Wärtsilä 25 engine platform, represents a significant milestone in the quest for more environmentally friendly transport operations. The President of Wärtsilä’s Marine Power business, Roger Holm, highlights the versatility of the engine, designed to operate not only on diesel and LNG, but now also on ammonia, a sustainable fuel that drives the transition to a greener future.

Efficiency and Sustainability: The Wärtsilä 25 Engine in Detail

Introduced in September 2022, the Wärtsilä 25 is a modular medium-speed 4-stroke engine, recognized for its upgradable modular structure and high power per cylinder. This engineering feat not only meets current demands but also projects into the future, offering a comprehensive solution that includes the AmmoniaPac for gas fuel, the WARMS ammonia release mitigation system, and the NOx (NOR) reducer for optimal exhaust treatment.

Partnerships for a Sustainable Future: Viridis Bulk Carriers at the Forefront

Viridis Bulk Carriers is ready to be a pioneer, being the first to adopt this innovative solution. As part of a strategic partnership with Amon Maritime, Mosvolds Rederi, and Navigare Logistics, Viridis aims to operate short-duration bulk carriers powered by ammonia, a sustainable fuel, in the North Sea. This ambitious initiative, partially funded by the Norwegian government’s Enova initiative, aims to launch the vessels in 2025, marking a significant advance toward environmental and sustainability goals.

By joining forces with Viridis Bulk Carriers, Wärtsilä not only drives innovation in the sector but also solidifies its ongoing commitment to developing sustainable technologies that reduce greenhouse gas emissions, such as the ammonia-powered engine. Stefan Nysjö, Vice President of Energy Supply at Wärtsilä Marine Power, emphasizes that the launch of the Wärtsilä 25 is just the beginning of a journey committed to a more sustainable future.
In this scenario of revolutionary changes, Wärtsilä continues to lead the way, not only with innovative engines but with an ambitious vision of a maritime sector whose engine is driven by sustainable fuels, where bulk carriers and ships sail powered by the clean force of ammonia fuel. The quest for more sustainable maritime transport is now a tangible reality, and Wärtsilä is at the forefront of this transformation.

Mother and daughter build a 70 m² house with more than 8,000 discarded glass bottles and impress with their creativity; known as the Casa de Sal, the property is located on Itamaracá Island, in Pernambuco.

The river that “dies” in the desert never reaches the sea and yet gives life to one of Africa’s largest natural refuges in a truly impressive way.

He transformed an abandoned plastic water tank into an underground house in the “hobbit hole” style, using only repurposed pallet wood, without heavy machinery or expensive labor.

China transforms desert-devastated area into the world’s largest artificial forest, planting trees for 60 years, blocking sand that reached Beijing, and creating a “green lung” of 92,000 hectares in a region once considered lost.

Toyota launches “family hybrid van” with 7 or 8 seats, 1.8 hybrid engine, fuel consumption of up to 23.8 km/l, and a price equivalent to about R$ 104,000 without taxes, below the Tiggo 8 Pro Plug-in Hybrid sold in Brazil: meet the Noah Hybrid 2026 in Japan.

Libya built over 4,000 kilometers of underground pipelines to bring water from the Sahara to coastal cities in a project that the government itself called the Eighth Wonder of the World.

Desert sand, previously discarded for being too smooth for concrete, becomes an ecological brick in the United Arab Emirates, dispensing with Portland cement, curing at room temperature, and attempting to transform dunes useless for construction into raw material for a new arid engineering.

Giant concrete tubes become futuristic micro-apartments in Hong Kong, with a diameter of 2.5 meters, 9.29 m² of internal space, and a proposal to fit homes where the city almost has no more space to live.

What changes with the new public transportation rules that can reduce pressure on fares and pave the way for zero fare in Brazil?

Driver who “holds” the left lane can receive a hefty fine and 4 points on their driver’s license even if they think they are going at the correct speed for the road.

Grandmother of eight graduates at 72, moves the family, and shows that a dream postponed for decades could still become a diploma.

Producers pierce PET bottles, bury them next to the plants, and create drip irrigation that delivers water directly to the roots and reduces waste in the garden.

Advancement in renewable energy: A R$ 150 million project launched by Petrobras and Finep aims to create state-of-the-art electrolyzers for green hydrogen, strengthening national research and preparing Brazil to compete in a billion-dollar energy market.

Illiterate or semi-literate grandmothers were trained to repair solar systems, open rural workshops, and light up homes that still depended on kerosene.

US$ 7 billion, green hydrogen, and steel with up to 95% less CO₂: the first green steel plant on the planet emerges in Sweden and targets Brazil as the next chapter

The world has bet on green hydrogen as the fuel of the future, but now faces the side effect: producing 1 kilogram requires about 9 liters of ultrapure water, and the largest projects on the planet are precisely in the driest regions of the Earth, where water is already scarce for people.

Africa has about 500,000 cell towers and most still burn diesel to operate, while companies rush to cover antennas with solar energy and avoid signal blackouts.
