Renewable Energy Generation Overview
The building renewables consist of two main plants - a renewable energy plant and a co-generation plant. A part of the co-gen plant (the ORC turbine) provides input for the renewable energy plant.
Please see the other knowledgebase sections for further details on each aspect of the system.
Co-Generation Plant
Water is heating to approximately 200°C by 4x solar thermal collectors on the roof, that hot water is harnessed by the following systems (in cascading order) with the output water still being potable.
- 180°C: Organic Rankine cycle Turbine. Max 10kW
- 120°C: Evaporative Chiller: Cooling 19kW, Heating 60kW.
- 60°C: Augment Building Hot Water Supply
Renewable Energy Plant
Inputs
- Photovoltaic Cells. 20kWp
- Organic Rankine cycle (ORC) turbine output from Co-Gen Plant. Max 10kW
- Wind Turbine: Max 12kW
- Hydrogen Fuel Cell: Max 10kW
Outputs
- Power stored in 2x 50kWh flow-technology batteries.
- Energy output to Building Microgrid (microgrid is not connected to the building main grid)
