Marine Battery Technology – It’s Time to Electrify Our Oceans

The maritime industry is a major contributor to greenhouse gas emissions, and is on track to contribute 17% of total global emissions by 2050 unless ship owners make significant changes. A large cargo ship will emit 5,000 tons of CO2 on an average cross-oceanic voyage, and in some cities port operations are responsible for as much as 50% of total emissions.

Lithium-ion and the high seas: a dangerous combination

There’s little tolerance for hazardous battery chemistries at sea. Lithium-ion fires are notoriously difficult to extinguish, and shipowners are worried about fighting fires on crowded vessels. This is especially true for large cargo ships that are often hundreds of miles from the nearest port.

The maritime sector has aggressive decarbonization targets, but extensive safety engineering makes lithium-ion systems expensive–up to 5 times higher on a per kWh basis. This has left many shipowners reliant on high-sulfur bunker fuel while they wait for next-generation blue and green fuels.

Low-cost, high-performance Alsym batteries can help reduce consumption of diesel fuel in and near ports, and can even be used safely to help regulate output from fuel-cell systems.

Reduce risks and costs

By using low-cost, inherently non-flammable raw materials with robust global supply chains, we aim to make electrification both safe and economically viable.

Alsym marine batteries can help reduce risks to crew and cargo, as well as lower insurance costs for fleet managers and shippers. They’re a safer alternative that can help the maritime industry meet IMO goals of zero net emissions by 2050.

Applications and Use Cases

Hybrid vessel applications include peak shaving, spinning reserve, low-speed arrival / departure, and hotel loads.

Applications for fully-electric vessels include short-sea shipping, OSVs, harbor vessels and ferries, as well as helping to regulate output from fuel-cell systems.

Alsym batteries can even be used on off-shore wind farms, oil and gas platforms, and drilling rigs.
