To date, batteries have emerged mainly in leisure boating, ferries and short-sea vessels, where ships are small size and cyclical routes allow occasional recharging. In larger deep-sea vessels, uptake is slow, but unprecedented global emissions regulations are driving change.

Battery application onboard ships can have multiple functional roles:

– Spinning reserve;

– Optimise the operating point of the generators;

– Peak shaving;

– Instant power in support of generators;

– Backup power;

– Harvest energy from on board equipment or renewables.

Batteries therefore help to improve the performance and energy efficiency of the overall vessel, while they can only fully power a vessel for a short distance or duration.

According to statistics as of 3 March 2021 from the Maritime Battery Forum, there are more than 450 ships that already have batteries installed on board or are on order.

The bar chart above shows an upward trend in recent years and we expect these numbers to increase further in the near future!

Sea Green Engineering attended the three-day virtual live conference “Electric & Hybrid Marine World Expo 2021 “.

It was a great opportunity to learn more about the next generation of electric and hybrid marine propulsion technologies in the marine industry.

We take the opportunity to thank the organizers, as well as all the delegates and speakers.

The objective is to support the strengthening of local action plans for bioeconomy, and will focus on marine and marine bio-based products.

Technologies solutions, innovative ideas, and challenges within the context of marine bio-based economy will be presented. There will also be a focus on research actions for a plastic-free Mediterranean Sea.

The oceans absorb around 30% of carbon dioxide (CO2) released into the atmosphere as a result of human activities.

It seems that the different carbon levels are measured in different depths. And the waters’ ability to absorb carbon depends on the temperature differences. As CO2 dissolves in seawaters it forms carbonic acid, decreasing the ocean’s pH. This is called ocean acidification. 50% of marine life is expected to be affected by ocean acidification. Its impact is now visible on coastal protection; ocean acidification weakens coral reefs shielding the coast line – another good reason to decrease CO2 emissions.
