Propane Power Generation
A flexible fuel option for on-site power and heat where pipeline gas is unavailable.
About Propane
Propane is a liquefied petroleum gas (LPG) produced as a by-product of natural gas processing and crude oil refining. It is stored and transported in liquid form under moderate pressure, allowing it to be supplied to sites without access to a natural gas pipeline.
Because propane can be stored on site in tanks and delivered by road, it provides a flexible and reliable fuel option for decentralised energy applications. It is commonly used in locations where pipeline gas infrastructure is unavailable, impractical or uneconomic.
When used as a fuel for gas engines, propane enables on-site electricity generation and combined heat and power (CHP). After vaporisation, propane is supplied to the engine in gaseous form and combusted in a similar way to other gaseous fuels.
Propane power generation is particularly well suited to applications requiring reliable energy supply, controllable heat output and flexibility of fuel delivery.
Benefits of Propane Power Generation
Propane power generation offers a number of practical benefits where alternative gas supplies are limited.
Using propane enables access to gaseous-fuel power generation in remote or off-grid locations, reducing reliance on diesel generation or grid electricity. On-site fuel storage improves energy security and resilience.
Gas engines operating on propane deliver stable and efficient performance with lower local emissions than diesel alternatives. When configured for CHP, recovered heat can be used to support heating, process requirements or space conditioning.
Propane systems can be deployed as a transitional or long-term solution, supporting agricultural, commercial and industrial applications where flexible fuel supply is required.

Applications and Deployment Scenarios
Propane Characteristics
Propane has a higher energy density than natural gas and a consistent, predictable fuel composition. It is stored as a liquid under pressure and vaporised prior to combustion in gas engines.
The stable quality of propane supports reliable engine operation with minimal variation in fuel characteristics, simplifying system design compared with variable waste-derived gases.
Propane Engine Power Generation and CHP Integration
Gas engines configured for propane operation use established combustion technology and control systems to deliver reliable power generation.
Systems can be designed for continuous or flexible operation and scaled to match site energy demand, from smaller installations through to multi-megawatt applications.
When operated in combined heat and power (CHP) mode, propane-fuelled gas engines generate electricity while recovering useful thermal energy in the form of hot water or steam. This heat can be used for space heating, process heating or hot water production, improving overall system efficiency.
Applications and Deployment Scenarios
Propane power generation is commonly used in:
• Greenhouses and horticultural facilities
• Agricultural and rural sites
• Commercial buildings in off-grid locations
• Temporary or decentralised energy projects
In greenhouse applications, recovered heat and carbon dioxide from combustion can be utilised to support plant growth while improving overall energy efficiency.
