Burando Energies has entered into a collaboration with World Fuel Services and Norwegian Cruise Line Holdings (NCLH) to supply sustainable marine fuels to cruise ships during port stays in the Netherlands.

The partnership will see biofuel blends delivered to vessels from NCLH's three brands — Norwegian Cruise Line, Oceania Cruises, and Regent Seven Seas Cruises — during the European season in 2025. Six vessels are expected to receive the alternative fuels, including Norwegian Prima.

Each delivery will feature a 30% blend of ISCC-certified, waste-based biodiesel, which the companies claim will achieve a reduction in greenhouse gas emissions compared to conventional marine fuels. The blend is designed as a drop-in fuel, compatible with existing engine infrastructure and operational protocols.

The initiative forms part of NCLH's Sail & Sustain programme, which focuses on environmental measures across the cruise line's global fleet. The company has been investing in cleaner fuel alternatives as part of its decarbonisation strategy.

Burando Energies will serve as the physical supplier and logistics partner, utilising its fleet of barges for bunkering services. Some of the company's vessels are equipped to handle green methanol and other sustainable marine fuels.

World Fuel Services will act as the project facilitator, coordinating execution across all parties involved in the fuel supply chain.

The collaboration represents an effort by cruise operators and fuel suppliers to reduce maritime emissions through the use of alternative fuels that are currently available in the market.

Biofuel blends have emerged as one of the near-term solutions for shipping companies seeking to reduce emissions while regulatory frameworks for other alternative fuels, such as ammonia and hydrogen, continue to develop.
