Maritime battery supplier Corvus Energy on Monday introduced its next generation Energy Storage System (ESS): Corvus Blue Whale.

“Once again we reinvent energy storage for ships,” states Geir Bjorkeli, CEO of Corvus Energy.

“When we launched the Corvus Orca Energy in 2016, we set a new standard for performance, safety and economics in a maritime ESS.

“The Corvus Orca Energy became an enormous success when launched and is now on more than 140 vessels worldwide.

“Looking back, we can see the significant role Corvus Orca Energy played in driving development towards a greener maritime industry.”

“Our goal is for Corvus Blue Whale to have a similar impact on maritime decarbonisation.”

The Corvus Blue Whale is specifically designed for cruise ships, Ro-Pax and Ro-Ro vessels.

“One battery cannot fit all applications,” says Halvard Hauso, EVP Sales and Marketing, explaining Corvus’ decision to expand its product range.

“To keep the emissions and costs as low as possible and allow for enough operational freedom, we need to adapt the batteries to the different vessel types.

“Corvus Orca Energy is ideal for applications that require high charge/discharge rate combined with high energy demand such as ferries and offshore vessels.

“Corvus Blue Whale is ideal for applications that require low charge/discharge rate combined with very high energy demand such as Cruise, Ro-Pax and Ro-Ro vessels.”

By using energy-dense battery cells and a space-saving design, Corvus Blue Whale’s volume per kWh is reduced by 50% and the weight per kWh is reduced by amazing 30%. Its modular design uses quick connectors for easy commissioning and reduced installation costs.

Like the Corvus Orca Energy, the new Corvus Blue Whale design uses passive air-cooling and incorporates Corvus’ patented single-cell thermal isolation to achieve the highest safety standard in the industry.

“Moreover, Corvus Blue Whale has no limitations with regards to size,” remarks Bjorkeli.

“We expect to see multi-megawatt hour ESSs deployed before long as cruise and passenger transportation operators grapple with zero-emissions regulations. We may look back on the launch of Corvus Blue Whale as another inflection point in the greening of the maritime industry.”

Singapore: Ofiniti, ONE trial direct platform integration to streamline bunker workflows

Ofiniti, the digital platform for maritime fuel operations, on Tuesday (21 July) said it has started a trial in Singapore, integrating FuelBoss directly with a bunker buyer’s own platform.

The company announced Singapore-headquartered container shipping firm Ocean Network Express (ONE) as its first buyer-side integration partner. 

“It is no coincidence we start in Singapore, as the Maritime and Port Authority of Singapore (MPA) remains at the forefront of digitalisation of all things bunkering,” the company said in a social media post.

In November 2023, MPA launched its digital bunkering platform, becoming the world’s first port to implement e-BDN. 

Ofiniti said every bunker delivery still runs on retyped data. 

“The buyer’s system says one thing, the supplier says another, and someone reconciles the gap by email, phone, or PDF. On every stem,” the company said. 

“We built FuelBoss to change this reality.”

With the integration, operational data now flows without manual re-entry, fewer reconciliation errors and faster processing and data, instead of documents, are readily available for procurement and claims workflows. 

“One connection will not transform the industry on its own, but digitalisation gets built one integration at a time. We are grateful to ONE for being willing to go first,” Ofiniti added.

Manifold Times previously reported ONE completing its successful trial of the electronic Bunker Delivery Note (e-BDN) with Shell. 

The e-BDN trial, using the digital bunkering solution developed by Angsana Technology, was conducted on 9 September 2023 at the Port of Singapore, with support from the MPA.

In March 2025, Ofiniti acquired Singapore-based Angsana Technology, with the entire Angsana team joining Ofiniti as part of the acquisition.

Genevos and Koedood Marine Group team up on maritime hydrogen fuel cell deployment

Marine fuel cell systems provider Genevos recently said the company signed a Letter of Intent (LOI) with engine supplier Koedood Marine Group to explore the deployment of hydrogen fuel cell systems for inland and coastal maritime transport. 

The LOI was signed by Phil Sharp, co-founder and CTO of Genevos, and Mühlheim, Business Development Director of Koedood Marine Group during the 2026 Advanced Maritime Technology Show in Amsterdam.

Building on Koedood’s proven experience in hydrogen maritime projects – including its ongoing work with Mitsubishi Heavy Industries and TNO on hydrogen engine development – the collaboration will explore how ready-to-use marine fuel cell systems can support shipowners and shipyards in the transition towards zero-emission operations. 

“Koedood has a strong reputation in the maritime sector and a deep understanding of vessel operators’ needs. This LOI is an important step in exploring how Genevos’ hydrogen fuel cell systems can be deployed more widely across inland and maritime applications, helping shipowners reduce onboard emissions with robust, practical and scalable clean power solutions,” said Sharp.

The collaboration aligns with growing market demand for rapidly deployable hydrogen solutions and the wider need to accelerate the adoption of zero-emission technologies across the maritime sector. 

“With this collaboration, we are further strengthening our portfolio of maritime energy solutions. Together with Genevos, we are exploring how we can support our customers in the adoption of hydrogen technology,” said Mühlheim.

DNV awards TADC to Econowind for VentoFoil 3-Series

Dutch wind-assisted propulsion technology firm Econowind on Wednesday (15 July) said it has received a Type Approval Design Certificate (TADC) from classification society DNV for its VentoFoil 3-Series boundary layer suction wing. 

The company said the certification confirms compliance with DNV’s ST-0511 standard for Wind-Assisted Propulsion Systems and enables easier integration of VentoFoils on DNV-classed vessels worldwide. 

Econowind added that the approval accelerates the deployment of wind propulsion across the shipping industry.

“DNV is one of the world’s leading classification societies. This TADC gives DNV-classed shipowners confidence that VentoFoils meet the highest industry standards,” said Chiel de Leeuw, Chief Commercial Officer at Econowind. 

“It simplifies the approval process for both retrofits and newbuilds. VentoFoils are ideal for late-stage design integration and retrofit projects. This is an important milestone for Econowind and for the wider adoption of wind-assisted ship propulsion.”

The 3-Series VentoFoil is Econowind’s best-selling suction wing to date, with over 150 units sold. The system actively harnesses wind power to generate forward thrust, helping to reduce fuel consumption and mitigate FuelEU penalties. The system includes a tilting foundation, allowing the wings to be tilted down during port operations or in adverse weather conditions, making it a flexible solution.

The TADC applies to the 16-meter VentoFoil 3-Series product design and supports easy integration into DNV-classed vessels without repeating the full design assessment process. This enables shipowners, shipyards, and project teams to move more efficiently from concept to installation, reducing project complexity and accelerating deployment. 

Hasso Hoffmeister, Senior Principal Engineer at DNV Maritime, said: “It is a great pleasure to award Econowind this new certificate. WAPS have been going from strength to strength over the past few years, from 2022 the number of vessels in operation has increased five times, and we’ve now topped the century mark. 

“And with the current advances in technology, materials, and production capacity in the segment, we expect this to accelerate. So, while the wind always changes, the shipping industry is likely to be sailing strong for years to come.”

Econowind expects the DNV Type Approval Design Certificate to accelerate adoption of the VentoFoil, particularly among shipowners seeking proven, independently certified technology that can support fuel savings, emissions reductions, and decarbonization goals.

MS Heinz of HS Schiffahrt is among the first vessels to sail under this TADC.The company said the approval builds on Econowind’s growing installed base and further strengthens confidence in wind-assisted ship propulsion as a practical solution to address energy scarcity and high fuel prices. 

In addition to the 3-Series, Econowind offers the 5-Series for the deep-sea market.
