2. What is Quad-generation?
Quad generation systems are some of the most advanced gas engine or turbine driven power plants in the world.
This power configuration by which, produces electricity, heat, and cooling, but also recovers carbon dioxide from
engine or turbine exhaust gas. The carbon dioxide can be sequestered to reduce emissions, or it can be used in
certain horticultural or industrial manufacturing processes.

3. Quad-generation System Integration
Generation: Electricity , Cooling , Heating and CO2
Application:
Produce Power for electrification
Provide chilled water for central air conditioning
system
Produce Hot water for heating
Separate CO2 for using in different industries

4. Quad-generation adopts the same technology as Tri-generation (CCHP), however, has the additional recovery of carbon
dioxide (CO2), a by-product of the combustion process to provide the highest levels of environmental performance and
offering the potential for low or zero carbon emissions.
In this way the carbon dioxide is captured from the engine or turbine exhaust and is cleaned through a specialist scrubbing
system which removes harmful contaminants.
Once the CO2 is scrubbed it can be used within greenhouses to aid photosynthesis to improve crop yield. Elsewhere, carbon
dioxide can be scrubbed to assist the carbonation process within the food & beverage manufacturing , bottling industry, or
other industry processes.

6. Benefits from a Quad-generation system installation?
Quad-generation is generally used in sectors where there is a demand for high grade carbon dioxide.
Many food and drink manufacturers, including those making carbonated drinks, beer and some bakery and processed food
products, use significant amounts of CO2 in production.
Carbon dioxide can also be used to promote fruit and vegetable growth in horticultural greenhouses. As well as improving
yields, pumping treated carbon dioxide into greenhouses can also help lock in carbon emissions, removing them from the
atmosphere.
Key Benefits
•Potential for low or zero carbon emissions
•Reduced operational costs versus separate purchase of electricity, heat, cooling and carbon dioxide.
•Uses all potential resources from gas utilization
•Has a wide range of potential applications

7. Potential Application
Carbon dioxide can be used for a number of purposes including:
 As a growth enhancer in plants
 Food & Beverage industry
 Industrial processes
Carbon dioxide is recovered and scrubbed from gas engines and is widely used in the horticultural industry. This carbon dioxide
is used by the plants in photosynthesis and physically becomes part of the plant, while it is being removed from the atmosphere
and therefore reduces carbon emissions. Alternatively carbon dioxide can be scrubbed and cleaned and then used as a
substance for drinks and food manufacture, such as carbonation in the soft drinks industry, or other industrial processes. Quad
generation provides the benefits of high efficiency generation, utilizing over 90% of the energy contained within the gas. It also
utilizes carbon dioxide, a by-product of the combustion process to give the highest levels of environment performance and
offers the potential for zero carbon emissions.
