Maturity stage TRL 7 - Prototype testing in the real world

A Net Zero Energy Building produces as much as it consumes every day. However, due to lack of storage capacity, it sometimes provides the grid with the surplus of energy and sometimes needs energy from the grid. To tackle this issue, Smart Energy Hub allows the building to store the surplus and use it when it is necessary. This solution combines batteries, for their fast switching capabilities, with a disruptive technology: an RSOC (Reconfigurable System-On-Chip) energy processor, capable of storing energy in the form of Hydrogen (water electrolysis function), and rendering it when needed in the form of heat and electricity (fuel cell function). Thanks to its software (modelling of building and the Smart Energy Hub) and to the adaptability of its product, any NZEB building can be rendered self-sufficient in energy (non grid-dependant).

The Environmental Benefits

  • CO2 emissions cut by 50% or more (depending on the country).
  • Energy produced locally.
  • RSOC processor recyclable to more than 90%.

The Financial Benefits

  • 50% lower energy bills (including maintenance).
