5 Reasons why Orca™ is the Perfect Name for Corvus Energy Storage Systems

5 Reasons why Orca™ is the Perfect Name for Corvus Energy Storage Systems

What’s in a name? Branding experts strive for a name that resonates with a product’s characteristics, that is universally understood, and emotes the experience of a user. Here are five similarities between Orca™ Energy Storage Systems (ESS) and majestic Orca whales that make Orca the perfect name for the newest Corvus ESS.

  1. Designed for Life at SeaTM. Resident Orca whales populations are found primarily in the North Pacific and Northeast Atlantic. Yes, these are the same waters in which Corvus Energy’s Orca ESS are increasingly found, with hybrid and all-electric ferries in the waters of Scandinavia, North Europe and British Columbia.

    Many transient and offshore Orca whale pods are known to travel great distances and have adapted to life in open water, similar to the new fleets of hybrid-electric cargo and offshore drilling service vessels being built or retrofitted with Corvus Energy Orca ESS.

Rather than take a single approach, Corvus Energy offers two Orca ESS product lines designed to meet the various needs of maritime customers. Orca Energy is ideal for applications that require large amounts of energy such as ferries and merchant vessels, while Orca Power was designed for applications that require a seamless response to dynamic power loads such as offshore supply vessels and port equipment.

  1. Breach Barriers. Nobody knows for sure why the Orca whale breaches. But one thing is for sure: sightings evoke awe and delight. We are thrilled that the maritime industry is responding similarly to the new Orca ESS product line. The Electric & Hybrid Marine Awards recently honored Corvus Energy with the 2017 ‘Innovation of the Year’

    In presenting the award, judges cited the Orca ESS product line’s enhanced safety, performance and, in particular, unparalleled energy density that results in dramatic drops in upfront and operating costs. With significantly improved ROI, Orca ESS is set to breach the barrier to adoption for many marine applications.

  2. At the Apex. Orca whales are apex predators, meaning that they have no natural predators. Now, we’re not saying that Corvus Energy has no competitors. But John Snyder, editor-in-chief and publisher of Marine Log, may have described Corvus market dominance best when he declared, “It’s hard to find a hybrid or electric marine power project that they don’t have a hand in.”

    Following the successful launch of Orca ESS at the Electric & Hybrid Marine World Expo in 2016, Corvus has won over 30 new projects totalling over 25MWh that will utilize Orca ESS. In total, 100+ projects utilize Corvus ESS, now totalling over 75MWh and 1.5 million operating hours. Corvus has unsurpassed experience and knowledge that enables revolutionary innovation.

  3. Human Safety at Sea. The Orca whale is often maligned as a ‘killer’ whale. The simple truth is that humans are not at risk from Orca whales at sea. Likewise, while doubts still surface about the safety of Li-ion battery systems at sea, these fears are unfounded for well-designed systems such as Corvus Energy’s Orca ESS.

Safety is paramount to the Orca ESS design, with a modular design that improves electrical safety during installation and operation, as well as advanced features to isolate thermal runway at the cell level and vent gas. Orca ESS has been tested and proven to meet or exceed marine safety standards, and Corvus Energy is the only supplier to carry DNV, Lloyd’s Register, ABS and BV product Type Approvals.

  1. Intelligence and Communications. Researchers are still uncovering the extent of social cooperation, vocalization and learned behaviors that indicate a high degree of intelligence in the Orca whale species.

    We draw the fifth parallel in this article to the intelligence and communications capabilities of the Orca ESS condition-based battery monitoring system, Watchman™ ESS advisory portal. Vigilant monitoring of the Orca ESS—from cell level to power system—ensures the system is operating at optimal performance and safety levels.

These are five reasons why Orca is the perfect name for the Corvus Energy Storage Systems. Subscribe to Corvus Energy Updates or Follow Corvus Energy on LinkedIn to keep current on all our news.

Compact Design and Streamlined Installation Improves ESS Payback

Compact Design and Streamlined Installation Improves ESS Payback

This is the final article in a series highlighting the five remarkable design features incorporated into the Orca™ Energy Storage System (ESS) product line design—a design that earned Corvus Energy the Electric & Hybrid Marine Technology 2017 Innovation of the Year award, as well as the BC TIA Technology Impact Award for Excellence in Product Innovation.

This fifth article describes the sleek, modular design of the Orca ESS that has reduced installation connection and commissioning times by up to 80% and installation costs by up to 50%.

 

Three reasons for faster, less expensive installation
This second generation of Corvus Energy’s highly acclaimed ESS incorporates the learned experiences from over six years of ESS commissioning in over 50 vessels in a variety of maritime environments. The three main reasons for lower installation and commissioning costs are outlined below.

  1. Compact Dimensions: Some of the most significant cost savings stem from a roughly 50% volume reduction and 10% weight reduction in the size of the Orca modules due to significantly higher energy density in the battery. Lower volume means that less space needs to be allocated on the vessel for the battery room.
  2. Safety and Thermal Management: There are typically significant cost savings in setting up the battery room. Higher cell-to-heatsink surface area and improved air flow result in a five-fold improvement in thermal management, which enables an air-cooled system to satisfy most use-cases.Further, Orca ESS has passed the Norwegian Maritime Authority’s (NMA) thermal runaway propagation Test 1—the most stringent test—witnessed by NMA and class society DNV GL. The safety, reliability, performance, and cost-reduction implications are outlined in Safety at Sea is the Top Priority for Corvus Energy Orca ESS.

    As a result, design and commissioning of the battery room and its infrastructure is less costly, with significantly simplified sprinkler, ventilation, and class/flag approvals.

  3. Integration and Factory Testing: Commissioning the Orca system itself is also faster and simplified, reducing installation time by up to 80% or about 1 person-week for a typical 1 MWh system. Much of the savings in field commissioning time comes from the Orca design, in which the power loop is integrated into the rack, along with the battery monitoring communications, so that both can be factory-tested.

In his remarks about awarding Orca ESS the Electric & Hybrid Marine Technology 2017 Innovation of the Year award, awards panel judge Martyn Lasek, editor, Ship & Bunker, said, “Battery technology is at the heart of electric and hybrid marine propulsion technology. Corvus is a true leader in this area.”

Rapid Adoption of Orca ESS
Since its introduction in June 2016, Orca ESS has been selected for over 30 projects totaling over 25 MWh, and the technology will only continue to improve the viability of hybrid and all-electric systems in a greater range of maritime applications.

High ESS Discharge/Charge Rates are Key to Fuel-Efficiency with Variable Loads

This is the fourth article in a series highlighting the five remarkable design features incorporated into the Orca™ Energy Storage System (ESS) product line design—a design that earned Corvus Energy the Electric & Hybrid Marine Technology 2017 Innovation of the Year award, as well as the BC TIA Technology Impact Award for Excellence in Product Innovation.

The Orca product line consists of two distinct ESS platforms—Orca Energy and Orca Power—each using different battery cell technology with optimized performance characteristics to match high energy demands or high power demands, respectively. In this article, we explore the technology and ideal uses of Orca Power ESS in maritime applications.

Industry’s Highest Discharge Rates
Discharge and charge rates of batteries are specified in a measure called the “C-Rating”. The C-Rating of a battery (or cell) indicates the maximum safe continuous discharge or charge rate. For example, a C-Rating of 10C means it can be discharged at 10 times that pack’s capacity. Continuous and peak C-Ratings are generally specified.

Orca Power ESS can discharge at peak rates of 15C and continuous rates of 10C—rates that simply cannot be attained by any other ESS supplier in the industry.

What are some of the applications that benefit from these high discharge and charge rates? Those with variable loads, says Sean Puchalski, Vice President of Strategic Marketing at Corvus Energy. “The economic benefit of the ESS is derived mostly from load leveling, peak shaving, and spinning reserve. The first two functions in particular are more pronounced in a vessel that must respond to high variation in propulsion loads.”

ESS-Assisted Dynamic Positioning and Peak Shaving Reduces Costs 20-30%
Bjørn-Johan Vartdal, Project Manager at Det Norske Veritas (DNV) agrees that vessels, such as offshore drill platform supply vessels, can benefit from a hybrid-electric system and integrated ESS. “When operating on dynamic positioning, there is a major fuel saving potential. When in harbour, too, the ship should be able to operate on the fuel cell and its battery power alone, which will reduce emissions significantly.”

To maintain the position of the vessel amid wind and waves, thrusters must respond quickly and dynamically. Traditionally, diesel or LNG generators have powered the thrusters, but slow generator ramp rates delay response time. Further, generators are typically sized for peak loads and may often operate in inefficient ranges. Consequently, a hybrid-electric system that can quickly draw high power from an ESS helps to both improve ramp rates and offset peak power demands—a practice known as peak shaving.

The primary benefit of a hybrid system for offshore supply vessels is a 20-30% reduction in fuel consumption and CO2 emissions achieved through smoother and more efficient operation of the generators. Moreover, generators can often be sized smaller to handle base loads as the peak loads will be absorbed by the ESS. So in addition to fuel efficiency, peak shaving may reduce generator running hours and may even negate the need to turn on additional generators.

High C-Rate Means Fast Charging
Let’s not forget that the ESS needs to be charged. Orca Power ESS can charge at peak rates of 13C and continuous rates of 5C, meaning that Orca Power ESS batteries can be quickly charged from shore charging stations and via energy recovery systems.

An example of a shore station ESS that takes advantage of quick discharge/charge using a Corvus ESS is the all-electric Norled ferry, Ampere. The ferry pauses only 10 minutes to unload and load vehicles. The shore ESS at each quay stores energy from the grid and performs a rapid battery-to-battery energy transfers with the on-board ESS while the ferry is docked. The top-up charges the ferry receives after each crossing allows it to make 34 crossing each day before receiving a full charge from the grid overnight.

Due to the quick charge rates, energy can also be recovered and stored in the ESS from port gantry cranes or off-loading equipment on vessels lowering their payload. Again, the high C-Rating means that a significant portion of the potential energy in elevated payloads can be converted into stored energy, further improving energy efficiency and ESS return on investment.

Rapid Adoption of Orca ESS
Whether Orca Power ESS is selected for its high discharge/charge rates and dynamic response, or Orca Energy ESS is selected for its high energy density and low cost per kWh, Orca ESS is a practical and economical solution for an increasing number of marine applications. Since its introduction in June 2016, Orca ESS has been selected for over 30 projects totaling over 25 MWh, and the technology will only continue to improve the viability of our systems in a greater range of maritime applications.

The Orca product line consists of two distinct ESS platforms—Orca Energy and Orca Power—each using different battery cell technology with optimized performance characteristics to match high energy demands or high power demands, respectively. In this article, we explore the technology, ideal uses, and three examples of Orca Energy ESS in marine applications.

Unparalleled Energy Density Reduces Cost by 40%
Orca Energy ESS offers a compact design, packing 1.6 MWh in a volume equivalent to a 20 foot shipping container. The key to its compactness is the high energy density of the lithium-ion battery cells in combination with Corvus’ innovative and award-winning battery module and pack designs—energy density that is unparalleled in the industry.

Moreover, the new design resulted in a 40% drop in the cost per kilowatt-hour of stored energy, opening the flood-gates for accelerated adoption of Corvus Energy’s lithium-ion battery energy storage systems.

Longer-Haul Vessels Now Among Ideal Uses
High energy density has made Orca Energy ESS an economically viable energy storage solution for a wide variety of uses. Orca Energy ESS performance is, however, optimized for energy storage uses with relatively constant power loads and discharge rates. As such, the Orca Energy ESS is well suited to electric or hybrid passenger and cargo ferries, tugs, supply vessels, cruise ships, and yachts. Operating at zero or low emissions in harbour and in sensitive marine environments is now more practical and affordable than ever.

Orca Energy ESS is also a viable alternative for spinning reserve, uninterruptible power supply (UPS) or fault ride-through for the entire power system or for subsystems.

Three examples of Reduced Emissions and Fuel Costs:

  1. Viking Princess supply vessel conserves an estimated 1 tonne of fuel per day. Wärtsilä selected Corvus Energy to supply Orca Energy ESS for the retrofit of a second Eidesvik offshore platform supply vessel, the Viking Princess, following the successful retrofit of the Viking Lady. The Viking Princess is a state-of-the-art offshore supply vessel designed to safely service offshore installations in the extremely harsh waters of the North Sea. The 533kWh Orca Energy ESS will be installed on the vessel in a hybrid arrangement. It replaces one LNG genset, approved by DNVGL & NMA as spinning reserve, and will result in one tonne of fuel savings per day.“Corvus Energy, and more specifically the Orca Energy ESS, was selected for its compelling safety, performance and return on investment,” said Dag Håvard Håvardsholm of Wärtsilä. “Based on the innovative approach of Orca and Corvus’ industry leading experience, ship owner Eidesvik has complete trust in this solution.”
  2. Hybrid chemical tanker runs fewer diesel generators. A new hybrid chemical tanker built for Rederiet Stenersen of Norway is the first vessel of its kind to utilize an ESS. Orca Energy ESS integrates with WE Tech Solutions’ hybrid power and propulsion systems, and will allow fewer diesel generators to run for certain operations—improving efficiency, reducing the emissions and lowering noise levels, and making it the most environmentally friendly chemical tanker ship in the Rederiet Stenersen fleet.“Corvus Energy’s industry leadership and experience made our selection of Orca a very straightforward decision,” said Niklas Jakobsson Project Manager at WE Tech. “The innovations Corvus has achieved on cost, safety and performance have created an extremely compelling energy storage solution.”
  3. Polar cruise vessel set for zero emissions. Two new polar expedition cruise vessels are being built for a European expedition cruise operator. Corvus will supply Orca Energy ESS to provide supplemental energy to the vessels in order to improve performance and reduce both operating costs and emissions.Each polar exploration vessel has been outfitted to handle up to 6MWh capacity of Orca Energy ESS to provide operational power. The vessels will be capable of cruising silently and emissions-free on ESS battery power alone into pristine locations, providing its passengers with the experience of exploring some of the world’s most exceptionally beautiful and unspoiled natural surroundings.

Rapid Adoption of Orca Energy ESS
“These latest orders show the viability of energy storage for the hybridization of longer-haul vessels,” said Halvard Hauso, SVP Business Development of Corvus Energy based in Bergen Norway. “As the cost of lithium ion batteries continues to improve we will see more and more applications beyond the traditional ferry and tugboat base.”

Whether Orca Energy is selected for its high energy density and low cost per kWh, or Orca Power is selected for its high discharge/charge rates and dynamic response, Orca ESS a practical and economical solution for an increasing number of marine applications. Since its introduction in June 2016, Orca ESS has been selected for over 30 projects totaling over 25 MWh, and the technology will only continue to improve the viability of our systems in a greater range of maritime applications.

Energy or Power – Corvus Energy Orca™ ESS Product Line Meets Both Differing Demands

Energy or Power – Corvus Energy Orca™ ESS Product Line Meets Both Differing Demands

This is the second article in a series highlighting the five remarkable design features incorporated into Corvus Energy’s Orca™ Energy Storage System (ESS) product line design—a design that earned Corvus Energy the Electric & Hybrid Marine Technology 2017 Innovation of the Year award, as well as the BC TIA Technology Impact Award for Excellence in Product Innovation.

Fundamental to Orca’s design is the recognition that there are multiple uses of ESS systems, and the performance requirements are significantly different depending on its use. “Even among the vessel types that are installing ESS today, there are differing requirements for what the products must do,” explains Sean Puchalski, Vice President at Corvus Energy. “These differences are mostly in terms of whether the vessel needs an ESS that can discharge evenly over an extended period of time (think all-electric ferry) or whether the vessel needs an ESS that can absorb and support large fleeting transient power loads (think offshore supply vessel dynamically positioning next to a drill rig in rough weather).”

The Orca product line consists of two distinct ESS platforms—Orca Energy and Orca Power—each using different battery cell technology with optimized performance characteristics to match high energy demands or high power demands, respectively.

Selecting ESS for High Energy or High Power
Let’s briefly revisit the terms energy and power, which are sometimes used interchangeably … but which are distinctly different. Energy is the “capacity for doing work”, while Power is the “rate of doing work” or the rate at which energy is consumed. The basic unit for energy is the joule (J), while the basic unit of power is the joule per second (J/s), known as the watt (W).

In terms of an ESS for marine vessels, the stored energy or capacity of the ESS is typically measured in kilowatt-hours (kWh) or megawatt-hours (MWh) meaning how much power can be delivered for a specified amount of time.

But, as Puchalski describes, as important for selecting the right ESS is the variability of the load—or demand for power—throughout the vessel’s operation profile and the time that the energy stored in the ESS is being discharged. Is the load relatively constant so that the ESS discharges evenly over time, as in a ferry on a fixed route crossing or an ESS used as battery-backup? Is peak demand intermittent and well above average demand, such as a tug that may spend less than 10% of its time at or near its full bollard pull rating? Or are there transient power loads, such as an offshore supply vessel using thrusters for dynamical positioning to maintain its position next to a drill rig?

Orca Energy ESS is optimized for energy storage uses with a relatively constant power load and discharge rate. It is ideally suited for use with all-electric short haul vessels, and is a viable alternative for spinning reserve, uninterruptible power supply (UPS) or fault ride-through for the entire power system or for subsystems. Due to high energy density, Orca Energy ESS offers a low cost per kWh of stored energy.

Orca Power ESS is an ideal energy source for uses with variable demand. It is designed for seamless response to dynamic power loads, and can deliver power quickly and efficiently to port cranes, charging stations, and offshore supply, exploration and production vessels. Due to extremely high C-ratings, Orca Power ESS offers the industry’s fastest discharge and charge rates.

Economic Benefit Improved with Correct ESS Matching
By correctly matching the appropriate ESS for the operating profile of the vessel and the intended use of the ESS, the economic payback is greatly enhanced—often doubling the return on investment.

In hybrid systems, the primary sources of an ESS’s economic benefit are reduced fuel consumption and lower generator maintenance cost due to efficient operation of fuel-based generators. An ESS can be used for spinning reserve, for instant response to transient loads, and for load balancing through peak shaving and ramping of dynamic loads where there is high variation in propulsion loads. These ESS functions allow generators to run less often and at optimal load for optimum fuel efficiency—resulting in reduced fuel consumption of 15%-75% depending on the application.

Further, the ESS can replace a generator and its associated capital, operating, and maintenance costs when used in fully electric vessels or in hybrid vessels for backup power, including spinning reserve.

Whether Orca Energy is selected for its high energy density and low cost per kWh, or Orca Power is selected for its high discharge/charge rates and dynamic response, Orca ESS is a practical and economical solution for an increasing number of marine applications. Since its introduction in June 2016, Orca ESS has been selected for over two dozen projects totaling over 20MWh, and the technology will only continue to improve the viability of these systems in a greater range of maritime applications.

Orca ESS from Corvus Energy has been selected to provide battery power to Farstad Shipping’s Platform Supply Vessel (PSV) Far Sun

Richmond, B.C. – July 10, 2017 – Corvus Energy is pleased to announce that it has been selected as the supplier of a lithium ion based energy storage system (ESS) for the hybridization of Farstad Shipping’s PSV Far Sun being integrated by Vard Electro, in the second half of 2017. The Orca Energy ESS from Corvus will supply electrical power to the PSV’s propulsion system electrical network to enable environmentally-friendly and lower cost operations.

The energy storage system will be utilized during all aspects of the PSV’s operation, particularly during Dynamic positioning and harbour operations where fuel consumption and emissions will be significantly reduced. Equally important to Farstad and Statoil (who maintains a long-term charter for the PSV), the ESS will increase safety through provision of spinning reserve for improved response time as well as increased redundancy.

“As we have experienced with many vessel types, the Orca ESS is ideally suited for the hybridization of the Far Sun PSV”, says Ronald Hansen, Global Service Manager of Corvus Energy. “Through close collaboration with Vard, our teams have developed a lean solution which meets the aggressive environmental, safety, performance and operating cost objectives of Farstad and Statoil.”

Statoil, an important client of Farstad Shipping, is focused on improved safety, efficient operations and reduced environmental impact. Through a long-term contractual relationship and a strong emphasis on reducing emissions, Statoil has been a key element in the efforts to have battery technology installed on board Far Sun.

“The energy storage system will provide significant savings for Farstad and Statoil over time, enabling the ship to more efficiently utilize energy produced by the generators, as well as simplifying the use of shore power. This will substantially reduce consumption and emissions. Another effect is less noise from ships in port”, says Christian Søvik, VP Global Services of Vard Electro.

As the leading manufacturer of energy storage systems for maritime applications, Corvus continues to lead the industry with 80+ installations utilizing a Corvus ESS, totaling over 45MWh and 1 million operating hours.
