Combined Heat & Power
CHP is ideal for horticultural companies who are looking to improve how efficiently they operate, drive down costs and increase turnover- thereby increasing profitability. Combined Heat and Power (CHP) is the simultaneous generation of electricity, CO2, and useful heat that can be stored and utilised when it is needed.
CHP is very efficient as over 90% of the energy produced is recovered and used on site and in the glasshouse, rather than wasted in the atmosphere. Another benefit is the CO2 generated by a natural gas fired CHP is significantly cleaner than the CO2 generated by a conventional gas fired boiler, and in comparison the CHP produces twice the amount of CO2 than a natural gas boiler which is useful to growers as it means they can introduce and maintain higher levels of CO2 without the excess heat, thereby increasing yields and the associated revenue. Therefore the CHP system is resourceful, environmentally friendly and virtually wasteless.
Combined Heat and Power is becoming increasingly relevant to the horticultural industry, due to the various benefits it brings to any horticultural business with a heat or cooling demand. A Combined Heat and Power plant also generates an income stream from the generation of electricity to the national grid. The provision of cheaper and more efficient heat to the horticulture business and the ability to provide CO2 to increase yields are the main benefits of the CHP.
CambridgeHOK, through its sister company Energy4Growth Ltd, is able to review your individual needs and facilities of your project and advise you on the most appropriate CHP solution for you. Therefore each business CHP model is individual.
It depends on:
- Export or internal use of generated electricity
- The potential secure an appropriate sized connection to the grid
- The type of fuel used
- Requirement for heating or cooling or both
- Opportunity to utilise high and low temperature heat
- The capacity to utilise CO2
- Reduced primary energy costs
- Stabilised electricity costs over a fixed period
- Reduced investment surrounding plant e.g. boilers
- Eligible for Enhanced Capital Allowances
- Potential ROCs eligibility (Biogas, Liquid Biofuel)
- Potential benefits from Renewable Heat Incentives
- Reduced base load electricity supply
- Additional security of supply
- Increased diversity on heating and hot water
- Steam raising capabilities on larger units
- Choice of multiple fuels
- Cooling provision using absorption chillers
- Reduced primary energy use
- Reduced CO2emissions
- Helps with carbon legislation compliance
- Reduced transmission losses from the grid
- Lower SOx emissions with the use of natural gas as a fuel
- Helps with Part L compliance
- Helps meet the CRC Energy Efficiency Scheme (CRCEES) targets
- Helps reduce carbon footprint
- Avoids Climate Change levy
Trigeneration systems supply energy in three forms: electricity, heat and chilled water. Chilled water is created by incorporating an absorption chiller into a Cogeneration system. Absorption chillers take the waste heat from a Cogeneration plant to make chilled water for cooling a building. This ensures the site is able to increase the operational hours of the plant with an increased utilisation of heat.
There are a number of benefits to trigeneration including:
- Onsite, high efficiency production of electricity and heat
- Reduced fuel and energy costs
- Lower electrical usage during peak summer demand
- Engine heat can be used to produce steam of hot water for onsite use
- Significant reductions in greenhouse gas emissions
- No harmful chemical pollutants since water is used as the refrigerant
