The objective of the POWERSTORE is to perform the final technology optimization and enter the market with a two-layered business model: 1) selling Powerstore ESS to end consumers, and 2) selling our coating material and the underlying technology to Li-ion manufacturers.
The specific objectives are:
· Scaling the coating material synthesis technology from 0,2 kg/hour to 10 kg/hour pilot scale
The system architecture as 4 basic pyrolysis reactors (burner; spray device and spray gas supply; precursor dosing system) was defined, calculated and designed. The system will have common pipe and filtering part.
The pilot prototype of one basic pyrolysis reactor with 2 kg/h productivity was made and tested for productivity parameters and for required powder parameters.
The final 10 kg/h system is in the part production at this moment. Complete system assembling and testing is planning in accordance with project schedule.
· Final optimisation of the precise coating precursor and additive chemistries
The risks to loose coating material technical parameters during reactor scaling (particle size, phase composition, purity) was mitigated by test process by the one basic pyrolysis reactor with 2 kg/h prototype. The process parameters and corresponding precursor and additive chemistries was adjusted to reach coating material requirements.
Final optimisation of 10 kg/h system will be made as a next step of the project.
· Piloting the technology in three ESS applications (home-user oriented residential Powerstore, semi-industrial renewable energy Powerstore and an industrial scale Powerstore) in collaboration with EnerTech
From Novmeber 2017 our ESS development team started direct work with potential customers to find right case to set up Powerstore ESS.
The Kuivajõe farm was visited several times in November and December of 2017 to estimate real customer problems and necessities. The complete review of Kuivajõe farm electricity system was made and offered ways to improve electrical and economical status of the farm by using Powerstore ESS. The requirements for semi-industrial renewable energy Powerstore was defined by this work.
The negotiations with Fortum Tartu AS was initiated in December 2017 to define real home-user oriented residential ESS and industrial scale ESS necessities and corresponding requirements for ESS.
The development of design and structure of three ESS systems was started based on these work results.
· Demonstrating Powerstore to 15-20 potential clients with different needs among the three Powerstore target segments and among Li-ion manufacturers
Mikromasch Eesti already started activities to promote and find targeted segments and clients for future commercial success. On the clear formulated concept we’re approaching potential customers, who might be users of ESS.
Together with Fortum Tartu AS we proposes and negotiating use of ESS for following subjects:
1. Compact “Green Energy” FC Welco football stadium, where solar panels are integrated on the tribune roof and due to different approach, systems from 120 kWh to 420 kWh can be used.
2. Charging station with solar panels for the EV taxi company -Elektritakso in Tartu.
3. UPS on the ESS base and also charging station for Tartu Airport (Tartu Lennujaam),where a solar panel generation is suggested.
