Hydrogen applications

The networking café on 3 June was again very busy. The hall of the Groote Sociëteit was completely filled. It was about Hydrogen Applications. Jan Pereboom of JP Energie Systemen gave a talk on the various possibilities for using hydrogen. Besides the various possibilities, he discussed the energy system at the Rijnstate site in Elst. This is a polyclinic. This means that no work is done in the evenings and weekends. As a result, only limited energy is used. On the roof of the building are 2600 m2 of solar panels that produce 200 kg of hydrogen via an electrolyser. The hydrogen is stored under relatively low pressure (around 30 Bar) in two cylindrical tanks. With the help of this hydrogen, electricity is produced again when needed. The heat released is used in the Polyclinic, thus achieving higher efficiency.

Jan indicated that it is difficult to realise such a project because there are almost no standards available for this application.

The sheets of the presentation can be found under 'Documents'.

Speaker: Jan Pereboom Director of JP-Energy Systems

During the KIVI seniors' circle's visit to the energy supply of the new hospital in Elst, we came across JP-Energiesystemen. We found this so interesting that we want to devote a lecture to it during the network café.

JP-Energiesystemen supports the generation, storage and reuse of sustainably generated energy. In this way, we help make your location more sustainable by making it partially or completely energy independent. Our intelligent systems make very efficient and effective use of renewable energy sources. This is done by producing, storing and reusing renewable gases, such as hydrogen and green gas.

  • Production, storage and reuse of renewable gases
  • Hydrogen-based energy systems
  • Biochemical production of green gas from waste streams
  • Hydrogen-based mobile generators for temporary energy supply

Working method

JP-Energiesystemen can also map out for you how a significant improvement in energy self-sufficiency and reliability could be realised at your site. We do this by performing an energy scan. In doing so, we look in detail at energy use and self-generation. By simulating energy supply and demand flows, we can offer practical insights into feasible solutions that are well-suited to your preferences and requirements.

Hospital, Rijnstate Elst

Our most recent project an energy system at Rijnstate in Elst (Gld). This was commissioned in the summer of 2023. At this hospital, a significant part of locally generated energy is stored and reused using hydrogen technology. With the current system configuration, a level of energy self-sufficiency of 60% is expected to be achieved. In this system, excess electricity is used to produce and store hydrogen locally. During periods when electricity demand exceeds supply, the stored hydrogen is subsequently converted to electricity using a fuel cell. The excess heat produced by the fuel cell is linked to the building's heating system. As a result, the overall efficiency of the system is almost 70%. An advanced and intelligent energy management system oversees and manages the entire energy system.

Energy storage based on PV, electrolysis, fuel cell and hydrogen.
