- Combined Heat Power Stations
- Similar to general power station
- Waste residual heat from steam generation used to heat water for homes/industry
- Advantages
- Lowers cost of electricity
- Reduces reliance on fossil fuels
- Lowers carbon dioxide emissions
- High energy efficiency
- Waste heat used
- Disadvantages
- Smaller scale CHP has a lower energy efficiency
- Electricity and hot water demand must be simultaneous
- High maintenance cost
- Applications
- When there's a requirement for space heating close to generator
- Low temperature hot water heating for local schemes
- Places that require low grade process heat
- Places with a year round heat demand e.g. hospitals
- Steam used for other industrial applications
- When demand for heat balances demand for electricity
- Biomass used in electricity generation
- Similar to general power station
