MSC cruise ship demonstrates fuel-cell technology

MSC Cruises’ latest ship, 

MSC World Europa, demonstrates the company’s strategy to decarbonise by cutting greenhouse gas emissions.

This ship was delivered from the Chantiers de l’Atlantique’s shipyard in Saint-Nazaire 24 October, with the latest power and propulsion technology on board.

MSC Cruise Management (UK) head of electrical engineering Steven Frey said this ship is powered by LNG and has a solid oxide fuel cell (SOFC) to run as a pilot project.

He told delegates at Riviera Maritime Media’s annual Maritime Hybrid, Electric & Hydrogen Fuel Cells Conference in Bergen, Norway, 27 October, the importance of testing and investing in technology to cut carbon emissions.

“We are working to get to zero emissions from multiple fronts, including digitalisation, workshops and partnerships, hybrid propulsion solutions, shore charging and new technologies, such as SOFC,” said Mr Frey. “We are starting a demonstration of a 500-kW SOFC on a ship, and we want to scale this technology up to 20 MW.”

Using power from shore during port stays is an important method for MSC to reduce ship emissions.

“All of our newbuilds are ready for shore power and we are retrofitting the existing fleet,” said Mr Frey. “Around 50% of our ships will be ready by 2023 and 65% by the end of next year. We have also signed a memorandum of understanding with Cruise Baltic to use shore power in 32 ports from 2024 when it is available.”

He said smaller cruise vessels need around 4.5 MW of power and MSC’s largest ships to need more than 10 MW from shore power to shut down engines.

Mr Frey said a combination of shore power and technology to reduce energy consumption and fuel usage is needed to cut cruise ship emissions.

“We are looking at ways to decarbonise by reducing energy consumption on the ships, by adding LED lighting and heat recovery, reducing hotel loads and using alternative fuels,” he said.

“We have a dedicated department dealing with energy efficiency and developing solutions for tracking data from our vessels, so we have a clear view of consumption,” Mr Frey added.

On the subject of fuels, MSC has already turned to LNG to cut pollutants and will consider other sources of energy.

“We are considering hydrogen as a fuel of the future and are using LNG now. MSC World Europa uses LNG fuel and has the SOFC pilot project. Other ships could run a fuel cell and LNG,” said Mr Frey.

World’s Largest Cruise Company Turns to Air Bubbles to Help Reduce Emissions

The world’s largest cruise shipping company has announced plans to install air lubrication technology on at least 20% of its fleet.

Carnival Corporation says the Air Lubrication Systems (ALS), which are already in use aboard four ships, will be added to five more ships this year with plans to install the technology on at least 10 more ships across a majority of its brands through 2027.

The hull drag-reducing technology is expected to reduce fuel consumption and carbon emissions by about 5% per ship, according to the company.

ALS technology, which first saw service within the Carnival Corporation fleet in 2016 with the introduction of AIDAprima, generates a cushion of air bubbles to lubricate the flat bottom of a ship’s hull, reducing friction between the ship and surrounding water, resulting in savings in energy and fuel consumption across a wide speed range.

Carnival Corporation is currently installing the Silverstream® System ALS on five more ships, including two ships in 2022 for its Princess Cruises and P&O Cruises (UK) brands. In addition, the company is planning at least 10 more installations for existing and newbuild ships across more than half of its cruise line brands, and it expects continued expansion of the ALS program. The expansion plans build on the success of four systems currently operating on ships from its AIDA Cruises and Princess Cruises brands.

“The installation of air lubrication technology is another example of our ongoing efforts to drive energy efficiency and reduce fuel consumption and emissions throughout our fleet,” said Bill Burke, chief maritime officer for Carnival Corporation. “We look forward to expanding the ALS program and furthering our long-term sustainability strategy to continually invest in a broad range of energy reduction initiatives, which has included over $350 million invested in energy efficiency improvements since 2016.”

Carnival Corporation has committed to reducing carbon emission intensity by 20% from its 2019 baseline by 2030 and has set an aspiration to achieve net carbon-neutral ship operations by 2050.

The “service power packages” upgrades will include ongoing installations throughout 2023 on ships belonging to the company’s nine brands – Carnival Cruise Line, Princess Cruises, Holland America Line, Seabourn, P&O Australia, Costa Cruises, Aida Cruises, P&O Cruises and Cunard.

Developed over the last six years and tailored to each vessel, upgrades to save energy include investments in variable speed drives and on-demand automation and controls, cooling enhancements, energy-saving LED lighting and more efficient heating and ventilation systems.

Carnival estimates the programme will deliver an average of 5-10% fuel savings per ship and is expected to reduce fleet-wide greenhouse gas emissions by more than 500,000 metric tons each year.

The upgrades will also result in around $150 million in fuel cost savings per year.

Carnival’s chief maritime officer Bill Burke said: “Based on our improved fleet composition, including adding six industry-leading LNG-powered ships, and our previous investments to increase efficiency and reduce emissions, our absolute carbon emissions peaked in 2011 despite significant capacity growth over the past decade.”

“These tailored service power packages further build on those efforts as part of our comprehensive approach to sustainability.”

The fleet-wide enhancements are part of Carnival’s energy efficiency investment programme. The company has committed to reducing carbon emission intensity by 20% from its 2019 baseline by 2030, supporting its efforts to achieve net carbon-neutral ship operations by 2050.
