Resources and expertise from CAE’s Engine Technology, Fuels, Lubricants, Rail and Marine activities; together with a proven track record of developing complex technologies for local and international clients established a unique capability for renewable energy. CAE Energy’s vision is to be the leading local supplier and developer of services and products to the fast growing African Biogas and Biomass energy industry.
Apart from CAE Energy developing and supplying local cost effective technologies we also manage develop, and engineer projects from conceptualisation to completion.
Furthermore CAE Energy is equipped to provide full Operation and Maintenance of energy projects, regardless of location, to ensure long term return on investment.
Under the Organergy Brand, CAE Energy is looking forward to assist you generating your own Energy and ultimately saving the environment.
CAE Energy supplies the following services to the Bio-Gas and Biomass market:
CAE Energy has also established relationships with our partners to deliver the following services to the Bio-Gas and Biomass market:
South Africa’s current relatively low cost of energy renders few imported technologies financially attractive and cost effective. CAE’s resources were used by CAE Energy to develop solutions tailor made for the African market.
CAE Energy’s in house technologies have been combined with established foreign technology partnerships to supply our clients with viable turn key solutions.
CAE Energy’s Products include:
CAE has developed a local equivalent of tried and tested International vertical reservoir digester design that is fully heated and stirred, optimising gas and energy production.Where applicable CAE Energy can also provide sealed Covered Lagoon type digesters for entry level solutions.
Easily digestible “wet” organic waste like fruit, vegetables, manure, sewage sludge, food, leaves, grass cuttings etc is usually fed to an anaerobic bio-digester that is sealed to enable the gas to be captured. This gas then requires a clean up process and is then fed to a gas engine which generates electricity. This is well established technology and Germany has over 3000 farms running such units. CAE has thoroughly investigated the world wide situation with these processes and related equipment and found that most project developers want to simply copy what has been done overseas. The cost of establishing such plants directly using overseas equipment and construction is too high and hence unattractive in the broader African context.part 2
CAE have developed local appropriate manufacturing techniques to be able to produce biogas electricity plants locally at a much reduced cost. This then also translates to local job creation and local supply options for maintenance and repair. All the projects generate foreign capital inflow from carbon trading, provided they are large enough, that contributes to financial viability. The sludge that is generated once the energy has been extracted still contains a significant amount of organic material, and all the fertilizer nutrients that were fed to the digester, and may be applied as a slurry or dewatered and converted to a granular natural fertilizer.part 1
CAE Energy have designed and are able to offer an acceptable biogas cleaning (scrubbing) solution to most electricity from biogas generating equipment – ensuring compliance with supplier warranties.
The process is affordable to operate, has low energy consumption and does not involve a continuous flow of environmentally damaging chemicals.
Scrubbing equipment is suited for both Agricultural and Landfill gas applications and is capable of removing H2S, Siloxanes and CO2 to satisfactory levels.
CAE Energy’s experience dates back to 1998 during conversion of diesel and petrol engines to operate on gas for various fuel companies and vehicle manufacturers.
Our engine and heavy current experience for the automotive and rail industry allowed CAE to build a biogas electricity plant in just 3 months
Understanding engine control and remote monitoring, detailed oil analysis results and hosting staff with combined engine build, service and repair experience of more than a century, enables CAE to provide the world class know how and support.
CAE have partnered with Guascor Power (a European supplier) of large (up to 1.2 MW) Biogas Electricity generating engines purposely built for 24 hr operation. CAE will supply, maintain, support and carry service parts of these worldwide proven engines.
CAE has taken the initiative in sourcing the newest Gasification technology available and forming international partnerships to enable local manufacture to create jobs and provide cost effective solutions.
Harder waste like wood chips, sawmill waste, municipal solid waste, plastics, tyres etc are processed in a gasification plant that combusts the material at a relatively low temperature to produce syngas that is then burnt at high temperature in a secondary combustion chamber. Two different plant designs are available and may be adapted to provide the optimum solution for different waste streams and customer requirements.
The lower initial burn temperature also allows for recovery of metals and glass for recycling purposes.The heat is captured and converted to steam which drives a steam turbine to generate electricity.part 2
Once again CAE has researched the technologies used overseas and has identified a new, but proven technology that is cost effective and highly efficient. CAE has negotiated with the developer to manufacture most components under license in South Africa to reduce cost. The cost of establishing such plants directly using overseas equipment and construction is too high and hence unattractive in the broader African context.
This then also translates to local job creation and local supply options for maintenance and repair.
All the projects generate foreign capital inflow from carbon trading, provided they are large enough, that contributes to financial viability. The ash that is generated may be used in fertilizer production from composting processes or as a fill material in road aggregates and concrete product manufacturing.part 1
With the support of Humphries Boerdery, CAE has taken the opportunity to demonstrate the possibilities of Bio-Gas electricity generation.
The plant situated in Bela-Bela Limpopo, acts as a valuable research tool to validate CAE technologies using biogas derived from pig manure.
It has been generating electricity consumed by the farm periodically for the past few months. The gas engine is capacity is far exceeding the farm's peak demand of 70kW.
Power management includes the capability to run in parallel to the utility, run in island mode, run in base load (fixed output topped up by utility), or import mode fixed utility consumption topped up by Bio-Gas generator.See video clip of engine running on Bio-Gas.
