Large numbers of stationary internal combustion engines are used globally to drive a wide variety of applications including electricity generation and compressor and hydraulic pump drives. The CESAR system can be incorporated in these applications to deliver the benefits of increased fuel efficiency and reduced emissions. Of particular interest, from an environmental point of view, is the landfill site application where methane gas is recovered from the decomposing waste and used to run engines that drive generators producing electricity for the grid.
Landfill gas is the natural by-product of the decomposition of solid waste in landfills and is comprised primarily of carbon dioxide and methane. Many landfill sites are now utilising this gas to power large spark ignition engines driving electrical generators connected to the national electricity grid. The benefits of this are two fold in that electrical energy is produced from a free resource and methane emissions are substantially reduced. The CESAR system can be run from a landfill gas powered engine to provide an anticipated 8% increase in electrical power output.
Not all landfill sites currently extract and burn the methane gas that is produced naturally. When methane is flamed in the presence of oxygen, such as an internal combustion engine, it creates Carbon Dioxide and water vapour. The resulting exhaust gas is significantly less polluting in green house gas terms than methane.
As the CESAR system can create an extra financial incentive, it could make it feasible for additional sites to develop gas-to-energy projects, hence giving a two-fold environmental benefit of providing additional cleanly generated energy and reducing methane gas emissions. This could also apply to currently untapped sources of methane such as sewage works and farms.
In addition to the landfill gas applications, there are generator sets fuelled by natural gas, bio gas and diesel which are all equally suitable for application of the CESAR system. The most suitable applications for CESAR are continuously operating engines, but there is also a potential market for CESAR to improve the efficiencies of engines providing power at mining and drilling projects.
