The University of Sheffield

The University of Sheffield Energy Institute has world-class battery research and testing facilities. The Institute is committed to furthering high-quality research in the field of energy storage. Immersa has parallel ambitions to provide renewable solutions across multiple sectors while embracing the latest advances in energy storage solutions.


This research and development project aims to harness new renewable technology into the university via a 600 V DC BUS. The new technology consisted of various chemistry fuel cells and solar.

By Utilising the existing solar installed within the university, our remit was to provide a suitable Energy Storage System to store the energy produced. The trial system would look at new technologies which will require online remote support, including remote firmware upgrades, software adjustments and reconfiguration of the DC Charges and the Power Control System.


As one of the UK’s most forward-thinking renewable consultants, Immersa has a proven track record in providing client-focused solutions using technology that performs in the most stringent conditions. Once we have established the full extent of the client’s needs, we provide the best solution to ensure we futureproof the technology as much as possible.

The project will be completed in several stages; the first stage will be to connect the solar PV to the battery system as a DC Coupled unit directly charging the battery and supplying the load. The second phase will be to use the fuel cells via an additional DC/DC converter to run a 600v DC bus which will then be connected to the battery using the battery DC to DC converter but without the Maximum Power Point Tracker (MPPT) Control.


Specifying the correct energy storage system is critical to any project, matching expected capacity with a robust solution. Immersa partner with the best manufactures around the globe to provide cost-effective, quality hardware.

We specified the Alpha ESS T100 Energy Storage System (ESS) ideal for commercial and industrial applications, matching the project’s criteria. With a 120 kWh capacity, the T100 is compatible with new installations and retrofits. German designed, these units have superb performance and a long lifespan.

Alpha ESS is one of the leading energy storage solutions and service providers in the globe. The company specialises in the residential and commercial market, aiming to deliver the most cost-effective and fit-for-purpose solutions. As the UK partner for Alpha, we had no hesitation in recommending this unit.

We look forward to continuing to work with The University of Sheffield and seeing the results from their research and development, which will allow Immersa and the industry as a whole to develop at a faster pace as we strive towards net-zero goals.
