Corvus Energy is the leading supplier of energy storage systems for maritime, oil and gas, subsea and port application. The solutions help to reduce fuel consumption and emissions and save costs.

From international shipping to local passenger transport, the maritime industry is largely dependent on fossil fuels to power its vessels.

Even though shipping is a relatively climate-friendly transport method, the combined greenhouse gas emissions from maritime transport across the globe are still enormous. In order to lower emissions, a push towards electric and hybrid vessels is oncoming.

Electrification, however, relies on a range of factors, including infrastructure upgrades, technological advances, operational and regulatory frameworks, as well as issues of cost.

Energy storage systems

Corvus Energy offers one of the widest ranges of energy storage systems (ESSs) in the maritime industry – for everything from subsea vehicles to cruise ships.

The ESSs can replace diesel engines in both fully electric and hybrid vessels, ensuring a reliable supply of power without the use of fossil fuels. In hybrid configurations, the batteries moreover allow remaining diesel engines to run with better fuel efficiency.

Corvus Energy’s systems have been installed on the world’s first electric car and passenger ferry, hybrid passenger ship, hybrid fishing vessel, hybrid offshore vessel, and hybrid high-speed ferry. When charged using renewable energy sources, vessels with Corvus Energy batteries can operate virtually emission-free.

Additionally, the ESSs can be installed at ports to allow for electric shore-side power supply, a central means for making ports emission-free.

Corvus Energy’s systems are built in Canada and Norway using patented technology. The batteries are purpose-built to suit the specific demands of each vessel or port.

Concrete benefits

Corvus Energy’s ESSs can be used for both electric and hybrid power setups for almost any type of vessel. For electric configurations, virtually all emissions are eliminated. For hybrid configurations, fuel savings and carbon emissions cuts are commonly between 15 and 25 per cent, with NOx cuts of between 30 and 40 per cent.

Corvus Energy estimates that one megaton of CO₂ equivalents has been eliminated through its projects to date.

Market potential

With increasingly stringent regulations and public pressure for green shipping and passenger transport, electric and hybrid solutions are gaining traction across the maritime industry. New vessel types and applications are exploring the potential of battery power, making energy storage solutions in high demand.

Corvus Energy has a fully automated lithium-ion battery factory in Bergen, Norway. The company has delivered energy storage systems for numerous vessels and projects around the world, including the world’s first electric car and passenger ferry. It is a member of the NCE Maritime CleanTech cluster.
