Cepsa Operates Europe’s First Hybrid Diesel-Electric Refueling Barge

With its modern design, Cepsa’s hybrid refueling barge reduces CO₂ emissions by more than 35%, improves fuel efficiency, and minimizes marine pollution. This project is not only a short-term solution to optimize maritime transportation but also lays the groundwork for the development of clean fuel technology in the shipping industry, moving toward a lower-emission future.

However, for this technology to drive large-scale change, the maritime sector must continue investing in alternative fuels such as hydrogen, green ammonia, and advanced biofuels. While Cepsa’s hybrid barge is an impressive model, additional policy support is needed to help ports and shipping companies swiftly adapt to this energy transition.

Cepsa’s Environmental Commitment in the Maritime Industry

Cepsa is one of Europe’s largest energy companies, operating across multiple sectors, from oil and gas exploration to renewable energy production. Recognizing the environmental impact of maritime transport, Cepsa has launched its “Positive Motion” strategy, committing to a 55% reduction in CO₂ emissions by 2030 and carbon neutrality by 2050.

Cepsa’s new hybrid barge has been deployed in Algeciras Bay, one of Europe’s most critical maritime hubs. This region is home to some of the busiest shipping routes in the world, with thousands of vessels passing through annually. Reducing emissions from ships in this area will have a significant positive impact on marine and air quality.

Key Features of Cepsa’s Hybrid Diesel-Electric Refueling Barge

Cepsa’s hybrid refueling barge incorporates cutting-edge technology, enabling it to operate with significantly lower emissions compared to conventional refueling ships. Some of its key features include:

1. Hybrid Diesel-Electric Engine for Reduced Emissions

The barge’s hybrid system consists of a next-generation diesel engine and a lithium-ion battery system, allowing it to operate on electric power during refueling operations in ports or shallow waters. This results in substantial reductions in CO₂, NOx, and SO₂ emissions—major contributors to air pollution.

2. Clean Fuel System and Biofuel Compatibility

Cepsa’s hybrid barge can operate not only on diesel but also on advanced biofuels (Biofuel B30-B100), further reducing CO₂ emissions compared to conventional fossil fuels. Biofuels are among the most viable alternatives for maritime shipping, as they can be used in existing ship engines without requiring modifications.

Additionally, Cepsa is researching the integration of green hydrogen into its fueling system, taking another step forward in the company’s decarbonization roadmap.

3. Smart Management and Automation System

The hybrid barge is equipped with an automated control system and smart sensors, optimizing fuel consumption, monitoring emissions, and adjusting operational modes based on real-time conditions. This system reduces fuel waste while improving performance in busy port environments.

Moreover, the barge can connect to port energy management systems to streamline refueling operations, ensuring maximum efficiency with minimal fuel consumption.

Impact of the Hybrid Barge on Maritime Transport

The deployment of Cepsa’s hybrid diesel-electric refueling barge provides several key benefits for the maritime industry:

CO₂ and Air Pollutant Reduction: Improves air quality in high-traffic port areas, which often experience high pollution levels due to cargo ship and refueling vessel operations.

Acceleration of the Green Fuel Transition: The use of biofuels and hybrid technology on refueling barges serves as a stepping stone for larger cargo ships to gradually transition to lower-emission fuels like green hydrogen and ammonia.

Paving the Way for Maritime Electrification: The success of hybrid refueling barges could lead to the future deployment of fully electric or hydrogen-powered refueling vessels.

Challenges and Future Prospects

Despite its many advantages, Cepsa’s hybrid refueling barge project faces several key challenges:

High Initial Investment Costs: Developing and operating hybrid vessels requires significantly higher capital investment than traditional diesel-powered ships.

Limited Clean Fuel Infrastructure: Most ports lack adequate infrastructure to supply biofuels or hydrogen to hybrid ships.

Evolving Regulations and Technical Standards: Maritime fuel regulations are still in development, making it challenging to implement hybrid models on a large scale.

However, with strong government support and a global push toward green shipping, Cepsa’s hybrid diesel-electric refueling barge model has high potential for expansion. If successfully scaled, this initiative could become a key solution for reducing CO₂ emissions in the global maritime industry.
