Heat Waste to Energy (W2E)

  • The heat is transferred to the power generation system via a suitable fluid including steam, pressure hot water, glycol, thermal oil etc
  • The heat is used for power generation using gTET’s revolutionary Organic Rankine Cycle (ORC) generator.
  • Heat that can be demonstrably renewable based such as geothermal or solar thermal result in the power station being classified as ‘renewable power
  • If the site also requires heat e.g drying, the power station can also be configured as Combined Heat & Power (CHP) delivering low grade heat for other processes.
  • The power stations are typically designed for minimal operating expense (OPEX) by avoiding regulated conditions such as full time manned high pressure steam turbine plants.
