As the world becomes increasingly aware of the impact of human activities on the environment, there is a growing demand for sustainable solutions in all sectors, including marine. From innovative exhaust emission technology to alternative fuels and fuel optimisation, the marine industry is making strides towards a more sustainable future. Here, Simon Farnfield, event director at Easy Fairs and organiser of Advanced Engineering, examines these technologies and their potential impact.
Exhaust emission technology
The International Maritime Organization (IMO) has implemented strict regulations on exhaust emissions to reduce the volume of harmful emissions the marine transportation industry emits. The regulations have driven the development of exhaust emission technology, with the aim of reducing those damaging emissions and improving air quality.
One such technology is Exhaust Gas Cleaning Systems (EGCS), also known as scrubbers. Scrubbers are installed on ships to remove sulphur and other pollutants from exhaust gases. This technology is an effective way to comply with IMO regulations while continuing to use traditional fuels such as heavy fuel oil (HFO).
Alternative fuels
The marine industry is also exploring the potential alternative fuels that can reduce the environmental impact of shipping. One of the most promising alternatives is liquefied natural gas (LNG), which produces lower emissions than traditional fuels such as HFO.
LNG has been gaining popularity in recent years, with more and more ships using it as a fuel source. According to a report by DNV GL, the number of LNG-fuelled vessels is expected to increase to around 300 by 2025. The report also states that the use of LNG as a fuel could reduce greenhouse gas emissions by up to 25 per cent.
Another alternative fuel that is gaining popularity is hydrogen. Hydrogen fuel cells can power ships without producing harmful emissions, making them an attractive option for the marine industry. While the technology is still in its early stages, there have been several successful trials of hydrogen-powered ships, including the world’s first hydrogen-powered ferry, which began operating in Norway in 2021.
Fuel optimisation
In addition to exhaust emission technology and alternative fuels, fuel optimisation is another key area where technology is improving sustainability in marine.
One way to optimise fuel consumption is through the use of data analytics. By collecting and analysing data on factors such as weather conditions, route planning, and engine performance, ship operators can identify areas where fuel consumption can be reduced — saving money and reducing the environmental impact. This data can also be used to develop predictive models that can help operators make more informed decisions about fuel consumption.
Another way to optimise fuel consumption is through energy-saving devices such as propeller fins and air lubrication systems. These devices reduce drag on the ship’s hull, which can improve fuel efficiency and reduce emissions. With a growing demand for sustainable technology for the marine transportation industry, more devices of this type are likely to be developed in the coming years.
Staying ahead of regulation
As the world’s demand for sustainable industry continues to mount, the marine industry must be prepared. For manufacturers and engineering organisations serving this sector, staying up to date with the latest technologies, trends and innovations is crucial to stay ahead.
Advanced Engineering, the trade fair held at the Birmingham National Exhibition Centre (NEC) on 1 and 2 November 2023, provides an excellent opportunity to learn about the latest sustainable technologies for industry.
