ENERGY EFFICIENCY

The energy efficency scenario provides a comprehensive overview of innovative or traditional technological aspects, innovatively developed, for increasing the effciency of ships and thus reduce their consequent emissions and environmental impact. As the scenario is primarily aimed at relevant authorities and experts working in R&D, it includes webinars, papers and projects devoted more to the policy-strategy and technology aspects.

With stricter IMO regulations on CO2 taking effect in 2023 and ambitious goals to reduce carbon intensity by 2030, the maritime industry is scrambling to clean up its act.

Conventional methods and equipment are now being reevaluated, upgraded or completely replaced. The difference between a short-term fix and a long-term sustainable option is how flexible vessels will be to use new energy sources or technology as they become viable.

The recent literature on renewable energy sources, technical and operational strategies for new and existing ships, technology maturity, and alternative fuels.

It is found that the IMO’s targets can be met by combining two or three technologies, or via a radical technology shift which can provide innovative, high-efficiency solutions from an environmental and economic standpoint

BEST PRACTICES

Transition to Clean Fuels such as liquefied natural gas (LNG) or hydrogen-powered propulsion systems.
Incorporate energy-efficient features like improved hull designs, advanced propulsion systems, and innovative power management systems to minimize energy consumption.
Maintain vessels properly to ensure they operate at peak efficiency. Periodic retrofits can update older ships with modern technologies, improving their emissions profile and energy performance.
Adjusting vessel speeds to optimize fuel efficiency can substantially reduce emissions.
Incorporate renewable energy sources such as wind, solar, and tidal power into ship operations.
