The International Maritime Organization (IMO) has adopted a revised Greenhouse Gas Strategy that sets a target for

Now, industry leaders are charting a course towards a cleaner future, one where the emissions of every vessel – both long-haul shipping and short-haul operations – can be reduced. 

ABB and the energy transition at sea

As a key partner in the maritime industry's transformation, ABB stands as a global technology leader in the energy transition. From pioneering electrification, automation and digitalization solutions to powering vessels and optimizing port operations, ABB's comprehensive portfolio is helping the maritime sector decrease emissions.

Shore-to-ship power: Electrifying ports

Even when  docked, ships require energy for on-board systems like lighting and refrigeration. One of the important   strategies for reducing emissions in the industry is shore-to-ship (STS) power.

Microgrids and energy storage on board

To further reduce reliance on fossil fuels, on-board microgrids are gaining traction. Microgrids are self-contained energy systems that can combine traditional and renewable energy sources such as green hydrogen with energy storage solutions like batteries. This allows for cleaner and more efficient power generation even at sea.

Energy storage is a critical component in the net zero journey. Batteries can store excess electricity generated from shore power or renewable sources on board, allowing vessels to operate on clean energy even when disconnected from land-based grids. Advanced battery technology with increased capacity and faster charging times is crucial for making this approach truly viable for long-distance voyages.

Electrifying the short haul

For shorter routes, particularly ferries, tugboats or other vessels operating within harbors and inland waterways, complete electrification is a viable solution. All-electric ferries and tugs, powered by battery packs and charged at terminals, are already operating in various parts of the world.

Data-driven operations

Digital technologies are also playing an important role in the maritime industry’s push for net zero. By installing sensors throughout a ship, it's possible to collect real-time data on various parameters – engine performance, fuel consumption, weather conditions, and cargo weight distribution. This data can be analyzed using advanced software to identify areas for improvement.

For example, AI and context-specific algorithms can analyze engine performance data to detect inefficiencies and recommend adjustments to optimize fuel burn. Additionally, real-time weather data can be used to optimize routing and sailing speeds, minimizing fuel consumption required to reach the destination.

Power energy management system (PEMS™) is another crucial tool for enhancing onboard efficiency. This system integrates data from various sources and provides a holistic view of a ship's energy consumption. PEMS™ can be used to monitor and control onboard systems, automatically adjusting power settings to optimize energy use based on real-time needs.
