uring the summer of 2020, STELLA Futura AB  was selected by Siemens Energy to partake in the Swedish Energy Agency funded  Zero Emission Hydrogen Turbine Center (ZEHTC) project to design and install a solar park equipped with a world-leading stationary battery energy storage system (BESS).  

STELLA’s solution will complete the ZEHTC demonstration plant which aims to show how hydrogen, gas turbines, renewable energy production and energy storage can work together in a future, flexible and sustainable energy system. ?Partners of the project are Siemens Energy AB, Chalmers University and the University of Bologna.

STELLA was chosen as the BESS supplier as – “we have the access and expertise to supply the Swedish energy market with, by many considered, the world’s foremost Battery Energy Storage System (BESS)” says STELLA’s CEO, Ulrika Tornerefelt. “We are incredibly satisfied and proud that, we were the only company to meet the extremely high demands that Siemens Energy AB has placed on battery technology and system integration.”

The BESS we deliver consists of a lithium-ion battery (NMC) with a prismatic battery cell. With this, maximum service life is obtained as it is integrated with a uniquely efficient control and optimization system. It is also this control system that is the basis for the high safety achieved with this battery system. Furthermore, the inverter has the market’s most impressive ability to handle frequencies in a frequency range as large as 45-54 Hz. This works all the way up to MW-sized BESS.

“STELLA Futura has successfully been able to provide Siemens Energy and the project “Zero Emission Hydrogen Turbine Center” with a unique energy storage solution combined with a solar PV park. STELLA were the only company, in our global tender, with the capability and competence to solve this task and offer Siemens Energy a stateof-the-art system. In addition, STELLA also included a leasing option for the battery solution, which has not been seen on the market before. I believe STELLA is in the forefront in delivering unique technology and business modelsThey have proven to understand our needs as their client, and delivered in close communication with our internal team at Siemens Energy.” 

 

–  Mattias Vieweg, Project Sponsor and Tech Project Manager at Siemens Energy AB

Due to the short lifetime of the project Siemens Energy were not looking to purchase a battery for its full 30 year or 8000 cycles expected lifetime. Therefore it was an ideal fit for STELLA’s financial solution: Financial leasing.

STELLA Futura is currently the only company offering leasing and rental solutions for battery system installations to commercial customers in the Nordic region.  

In the spring of 2021, the plant will be put into operation. Kraftpojkarna and Solarwork were chosen as partners for the actual installations of the solar park. Knowledge seminars will be arranged as well as a few unique site visits to show how the technology works where participants are given an insight into how the innovative energy systems of the future may look like.
