Energy Storage Systems (ESS)

Corvus Energy’s ESS portfolio is built on field‑proven safety, reliability, and performance. The company’s NxtGen architecture integrates modular design, universal components, and advanced monitoring tools to reduce installation time, simplify maintenance, and extend system lifetime. The brochure highlights that Corvus systems offer “state‑of‑the‑art, cloud‑based monitoring” and “online portal for realtime performance reports”, ensuring operators have full insight into system health and efficiency.

Corvus Orca ESS

The Corvus Orca is the world’s most installed marine battery system, powering more than 700 vessels globally. It set a new industry benchmark when launched in 2016, offering high C‑rate capability, robust safety features, and low lifecycle cost. The brochure notes that “no other Energy Storage System can compete with the installation count of the Corvus Orca”, underscoring its dominance in hybrid and electric vessel applications.

Corvus Blue Whale NxtGen ESS

Designed for large‑scale installations from 1 MWh to over 200 MWh, Blue Whale NxtGen delivers exceptional volumetric and gravimetric energy density. It is optimized for long‑duration, slow‑charge operational profiles such as cruise ships, Ro‑Pax vessels, and merchant fleets. The system offers up to 50% volume reduction compared to Orca, making it ideal for vessels requiring extended zero‑emission operation.

Corvus Dolphin NxtGen – Energy

This lightweight, high‑energy ESS is tailored for vessels with long, slow charge/discharge cycles. Its rack‑free design maximizes installation flexibility, and it is available in both air‑ and liquid‑cooled variants. The brochure emphasizes its suitability for “tourist vessels, canal boats, yachts, sightseeing vessels, and ferries”, where space and weight are critical.

Corvus Dolphin NxtGen – Power

Engineered for high‑power applications, Dolphin Power supports rapid charge/discharge cycles and delivers exceptional power density. It is ideal for fast ferries, tugs, offshore vessels, and wind support ships. Like all Corvus systems, it features “passive single‑cell Thermal Runaway protection”, ensuring unmatched safety.

Fuel Cell Systems (FCS)

To extend zero‑emission range beyond battery‑only operation, Corvus offers the Pelican Fuel Cell System—an inherently gas‑safe hydrogen fuel cell solution built on Toyota’s proven technology. The brochure describes Pelican as “one of the safest and most advanced marine fuel cell systems available”, designed for scalable power from 340 kW to 10 MW.

Pelican is ideal for vessels operating where hydrogen supply is available, including ferries, container feeders, SOVs, and coastal transport. Integrated with Corvus batteries, it enables optimal load balancing and extended emission‑free operation.
