First Aid for a Sustainable Ship - Large Fishing Trawler

This is a case study on how to decarbonize a fishing trawler - the Jacobus Maria - using shore power, battery hybrid EES and biofuels. 20% CO2 reduction is achieved, half of which stems from the use of biofuels (HVO). The hybrid battery pack is economically not feasible with the assumptions used and the operational profile. The Jacobus Maria has 1 MW installed engine capacity. Total cost would be at least €1M. 10% CO2 reduction can be achieved with approx. €50k.

Inside a Battery Container

The Corvus BOB (Battery On Board) is a standardized, class-approved, modular battery room solution available in 10-foot and 20-foot ISO high-cube container sizes. The complete system comes with battery, monitoring system, HVAC , TR exhaust, plus firefighting and detection system. The plug and play battery room simplifies integration into any system integrator’s power management system on board a ship. The battery cells have passive thermal runaway protection, and are type-approved according to DNV.

Maritime Battery Forum with Syb ten Cate Hoedemaker

During the lunch and learn, current forum Director Syb ten Cate Hoedemaker will exchange knowledge and experience from the usage of batteries within the shipping and offshore industries. You will learn which batteries will suit your vessel, plus discover the costs and payback for different operational modes. Which battery suits your vessel, your needs, your operational profile? This is the key question discussed in this lunch and learn with Maritime Battery Forum.

Battery Recycling, made by Northvolt

Northvolt has partnered with Hydro to establish a first-of-its-kind battery recycling facility. The recycling plant will come online in 2021 in Fredrikstad, outside of Oslo. At commissioning, the Hydro Volt plant will have initial capacity to process more than 8,000 tonnes of batteries per year – roughly the equivalent of 23,000 moderately sized EV batteries. Northvolt is aiming for 50% recycled material in new cells by 2030.

The Big Friendly Hybrid Giant

The North Sea Giant, a Norwegian offshore construction vessel, is the first DNV class-approved ‘hybrid’ DP3 vessel with three batteries on-board that have a total capacity of 2.034 kWh. The batteries have been installed in an upgrade and serve the purpose of spinning reserve, peak shaving and load leveling. Since then, fuel consumption is reduced in all operational modes with over 2 million liters of diesel per year, saving up to 30% fuel.

Hurtigruten’s New Hybrid Ships

Designed in 2017 and launched in 2018, Hurtigreten has launched two new hybrid cruise vessels, the MS Roald Amundsen and MS Fridjof Nansen, that can sail fully electric for up to 30 minutes. Not only will it significantly reduce emissions, a hybrid system is also extremely quit. Arctic exploration has never been so much fun!

Tesla’s Battery Day from a Maritime Perspective

Using Tesla’s announcements of Battery Day, DNV expects the cost of batteries to be reduced by 56% (measured in $/kWh) by 2025. Worldwide, DNV predicts that passenger electric vehicles are likely to start outselling their internal combustion engine counterparts from 2032 onwards. In North America, Europe and China this will take place well before 2030.  Tesla’s success could spill over from land-based vehicles into adjacent transport sectors. On the assumption of success on all fronts, Tesla will achieve the critical battery density for short range electric airplanes – namely 400 Wh/kg with high cycle life.

Recycling vehicle batteries

Helen Czerski went to Wendeburg in Germany to see if it really is possible to recycle the materials in vehicle batteries. She shows how this new and rapidly growing industry is developing and coming up with some interesting results, with lithium-iron batteries being economically recycled up to 70% (91% including graphite). Please send this to all the people you know who say 'what about when we throw all these fancy batteries into landfill.

The Trouble with Cobalt by Joe Scott

Electric cars have a dark secret - cobalt. The element that is in almost all lithium-ion batteries is often considered a conflict mineral because half of all cobalt reserves are found in the Democratic Republic of Congo, a troubled region with over a century of instability. But is it as bad as the anti-EV crowd has led us to believe? What's the reality of the situation, and what are some of the solutions?

How the North Sea Giant saves two million liters of diesel every year

The North Sea Giant saves two million liters of diesel every year. It has installed three battery packs and a distribution system from Wärtsilä, which will dramatically reduce fuel consumption. The North Sea Giant is one of the world's largest construction ships, and was the first vessel in its class to have a hybrid system installed on board.

LFP Battery Fire Hazard by FM Global

This video shows the potential fire hazard of an 83 kWh Energy Storage System comprised of Lithium Iron Phosphate batteries. The ESS had an overall electrical capacity of 83 kWh and ≥ 95% state-of-charge. No protection systems were active. Three heaters plus a propane pilot flame were installed to ensure vent gas ignition (!). The results from this test may not be representative of other LFP based systems.

Transocean Spitsbergen goes Hybrid

In April 2019, the Transocean Spitsbergen successfully and sagely installed an electric Energy Storage System (ESS) of 5.6 [MW] on-board. This allowed the semi-submersible drillship to run in hybrid mode during DP3, reducing fuel consumption by about 15%. Economic incentives were provided in the fuel-clause and by the Norwegian NOx Fund.
