Fortum Hydroplant

LUND, SWEDEN; April 21, 2021 – The Swedish cleantech company Comsys AB announces today that it has delivered a novel, 1MW/250KWh battery energy storage system, or BESS, using replaced PHEV batteries, to a hydroelectric power plant operated by Fortum.

The facility is among the world’s first commercial supply-side BESS installations using batteries from vehicle, and a part of Fortum’s strategy to drive the change for a cleaner world. Incorporating 48 PHEV batteries supplied by Volvo Cars, this solution is engineered and built by Comsys to get the most out of PHEV batteries whilst also providing significantly faster frequency regulation.

According to Dan Liljengren, Business Development & Head of Research and Innovation at Comsys, the solution is a response to increased demands on energy suppliers to maintain grid stability amidst growing fluctuations caused by all the ways that energy is generated and consumed today.

“After being approached by Fortum, we began developing a new storage solution capable of reliably, sustainably and rapidly storing and discharging power. We call it DES™, short for ‘Dynamic Energy Storage,’ because it’s fast, easy to deploy, modular and scalable.”

The new solution leverages Comsys’s expertise in perfecting power quality by arranging the batteries into “strings.” Each string consists of a Comsys ADF (AC/DC converter) connected to three PHEV batteries. For the facility, 16 strings are used to provide a capacity of 1MW/250KWh and frequency regulation with a response time of less than a milli seconds, faster than what hydroelectric turbines are capable of providing on their own.

According to Erik Tutzauer, Project Manager at Fortum, in addition to the operational benefits for the hydropower plant, there are also significant environmental benefits and new opportunities made possible through re-use of lithium-ion batteries:

“Thanks to the experience and ingenuity of Comsys and a can-do attitude, we have overcome many challenges together. We have gained valuable learnings on how to re-purpose used batteries that previously have served in electric cars into high-quality industrial energy storage systems. Comsys and Fortum have proven to be an exceptionally good combination for providing energy solutions for several industries.”

About Comsys AB
Comsys AB, a cleantech company based in Lund Sweden, develops digital energy control methods and products to optimize and improve energy flow in a wide variety of applications and help customers to meet increasingly challenging demands set by standards and utility companies. Our technologies provide robust solutions for both grid operators and applications within industrial automation, building automation, data centers and the marine sector, to name just a few. They are also being increasingly used in electricity production and energy storage, primarily from solar and wind, in order to meet the constantly growing demands by grid operator owners around the world.

The marine segment has tough requirements when it comes to power quality and harmonics. Did you know that the International Association of Classification Societies (IACS) has revised the unified requirement for ships' power quality? UR E24 REV1 focuses on the power quality and harmonics. In line with most individual classification societies, the UR E24 REV1 has the maximum total harmonic distortion THDu up to 49th harmonic set at 8%. A new and important factor is that they also require you to constantly measure the voltage distortion.

The UR E24 REV1 applies to all ships contracted for construction after 1 July 2020, and requires that they:

  • Continuously monitor the levels of harmonic distortion experienced on the main busbar
  • Alarm when exceeding the distortion limit
  • Keep an electronic or paper log covering distortion level

There are also confirmed rules that are waiting for implementation date. The new rules will be that:

  •  The ship shall, annually, measure harmonics in seagoing conditions in a professional manner
  • A report shall be presented to the surveyor at periodical machinery survey

With the revised IACS rules we believe and hope that power quality is not only a paragraph in the rule book but also an item that is highlighted when assessing ships power.

 (LUND, SWEDEN; November 20, 2020)  – The Swedish cleantech company Comsys AB announces that its ADF P300 will now be delivered with a new and improved cabinet solution offering greater flexibility, safety and ingress protection, as well as time-saving service features.

During a virtual customer event yesterday Comsys introduced its next generation ADF P300 featuring a new, modernized cabinet design to be implemented for its entire range of floor mounted active dynamic filter products. The design was adopted as a way to bring significant benefits to customers, installers, maintenance technicians and system integrators alike. Models will be available in three widths, 40, 60 and 80 cm, and the narrowest will come in an IP54 version as well for enhanced protection against the elements.

According to Jonas Persson, Head of Products & Quality at Comsys, the new cabinet solution provides exceptional flexibility compared to the existing range.

“Now customers will be able to choose a solution for exactly the current they need and with a footprint that will best suit them based on how many modules and how much expansion capacity they require. This is especially important in the marine sector where space onboard vessels is very limited.”

Other major benefits says Persson include improved personal safety and serviceability, standardization between products, and support for the company’s upcoming v3 and v4 modules.

”System Integrators will appreciate the fact that the redesigned control module can be installed in virtually any cabinet, and installers and maintenance staff are really going to love it because it’s safer and can save them hours of work.”

(LUND, SWEDEN; November 16, 2020)  – The Swedish cleantech company Comsys AB announced today that it has successfully demonstrated the repurposing of used EV batteries for industrial peak shaving applications.

Recent trials of an onsite energy storage installation built by Comsys using swapped-out EV batteries has enabled a sawmill in Germany to increase production by 100% by making it possible to run a second saw without limitation. The objective of the project was to study this second-life battery application as an alternative to installing additional capacity from the grid, which is typically too costly, to supply the peaks of a highly variable load.

The test project is a response to the growing opportunity for the power sector resulting from rising global growth of electric vehicles – stationary storage powered by used EV batteries. This is a relatively new opportunity that, according to an article published by McKinsey & Company in April of 2019, “could exceed 200 gigawatt-hours by 2030.” Dan Liljengren, Head of Research and Innovation at Comsys, explains why the sawmill made a good choice for the trials.

“In applications like sawmills, the power is very volatile due to the significant difference between high load and low load, and the demand fluctuates as a natural part of the sawing process. For such applications, often situated in remote areas, a battery installation can supply the saws at high load demand to supplement the limited power available from the grid. At low load the battery is charged.”

The result of the pilot trials showed that the sawmill was able to utilize the power connection to the maximum and overcome a previous limitation of only using one of two big saws simultaneously, thus doubling production capacity. Liljengren says that Comsys’ solution, which is modular and fully scalable to fit the needs of various industries, offers several significant advantages.

“Not only does it allow the owner to sidestep large investments in grid infrastructure, but it also provides quick response, contributes to a circular economy and can save industries money by not having to pay for electricity at peak demand.”
