Biogas System Components


Simons Green Energy can deliver the entire waste to energy solution to your business. We integrate different technologies and system components according to your site’s requirements.



Simons Green Energy works with industry partners to  design, manufacture and install Anaerobic Digester systems (which may include covered lagoons and mixed engineered systems). We manage all aspects of the installation from civil works through to mechanical works and commissioning.

For farm and landfill application, with existing sewage ponds or landfill sites, over tight covering with a specially engineered robust and flexible membrane is a relatively low-cost way of capturing Biogas. Capturing and flaring these methane emissions provides an immediate 20- fold  reduction in carbon footprint!  Using the  energy value of the methane to offset electricity and natural gas provides even greater financial and environmental benefits. More complex digester solutions may be required to improve the yield and provide additional control over Biogas production. Simons Green Energy can engineer these to suit site needs.


We offer a range of boilers configured to operate on Biogas or on a combination of natural gas, propane and Biogas. Simons Boilers has over 80 years’ experience in boiler manufacture and sales and we can design and install a Biogas boiler to suit any size and output requirement.


Our Biogas Cogeneration Systems range from micro-scale CHP units of 7.5 kW through to large-scale systems of over 2 MW of electrical capacity. The ideal configuration is site-specific and the best option for your business will be determined following a detailed energy, process and economic analysis.


Simons Green Energy is the exclusive Australian distributors of YANMAR Micro-Cogeneration and ENER-G Cogeneration units. These reciprocating enginebased CHP units provide a proven and simple method for producing heat and power from Biogas at a low cost.

ENER-G CHP 81 kWe to 1,558 kWe packaged units can be configured with  MAN, ENER-G, MTU, Perkins, Caterpillar Biogas engines.

YANMAR 25 kW Micro CHP are compact, stand alone “plug and play” units, with integrated dump radiator, ventilation and built-in inverter. For outdoor or indoor installation, these units can be “daisy-chained” for increased output and will load follow to suit any site’s instantaneous electricity demand.


Qnergy’s  7.5 kW Stirling Engine based CHP 

Qnergy’s 7.5 kW Stirling Engine based CHP units are manufactured in the USA. Unlike conventional reciprocating engines, Stirling engines are an external combustion design. This means they can operate with a very wide variety of fuels including Biogas, natural gas and wood waste. Stirling engines have the advantage of a high tolerance to moisture and H2S content. The Qnergy system efficiently generates electricity while generating a substantial amount of hot water.


Simons Green Energy can supply micro turbines from leading international manufacturers. They have a proven track record for reliability in Biogas applications, low maintenance costs and good thermal efficiency.


Simons Green Energy can supply all supporting equipment necessary for a complete Biogas system sourced from reputable local and international suppliers. This equipment includes:

  • Flares
  • Blowers
  • H2S Scrubbers
  • De-Humidifiers
  • Knock-out Pots
  • Flame Arresters
