Natural gas fuelled application:
Natural gas benefits from factors, such as high heating value, attractive cost and ease of transportation and supply combined with the fact that it produces 40 to 50% less CO2, than when coal is burned to produce the same amount of energy. These characteristics make natural gas particularly suited for use in Cogeneration systems.
Biogas fuelled applications:
Whilst the energy produced by a CHP system has increased energy efficiency than traditional centralised generation, it is not technically classed as a source of renewable energy unless it is fuelled by biogas.
Biogas produces no net carbon emissions. Biogas fuelled Cogeneration also benefits from legal frameworks that offer additional financial incentives to companies that introduce such schemes, such as, the renewable obligation and the allocation of Renewable Obligations Certificates (ROC's). ROC's significantly increase the value of the electricity produced by the CHP system, making a significant contribution to the reduction of greenhouse gases.
At ENER·G we have the technology to convert natural gas fuelled engines to run on Biogas. Typically these sorts of applications are found at wastewater treatment sites that use sludge digesters (anaerobic process) to produce Biogas. The heat from the Cogeneration system is then put back into the digester, which further increases the efficiency of the system.
As well as wastewater treatment sites using anaerobic digesters, there are many other applications. Whenever organic material can be broken down in a controlled environment Biogas will be produced. Such examples are from food, sugar, paper-pulp and landfill gas to name a few.
Biodiesel fuelled applications:
Renewables are becoming a more viable option in new and existing buildings particularly when combined with CHP. Biodiesel CHP has the potential to be a leading renewable solution for many buildings. The biodiesel fuel is made from biomass such as vegetable oils, therefore, it is biodegradable. It is seen as 'clean energy' as when it is burned does not contribute carbon dioxide towards greenhouse gas emissions (carbon neutral). Biodiesel is not just environmentally friendly but is also a cost-competitive form of energy.
Propane applications
Quite often, there is the potential for a CHP scheme but the site has no access to mains gas, especially so for sites in remote places. In this situation, ENER·G can convert a natural gas fuelled engine to run on liquid petroleum gas (LPG).
