GE Jenbacher – Biogas Engines
About the Company:
The disposal and treatment of biological waste are major challenges for many industries. Anaerobic fermentation—a superior alternative to composting—provides a unique solution for the management of a wide range of organic substances. Created during anaerobic fermentation, biogas serves as a high-energy, renewable fuel that can be used as a substitute for fossil fuels. Biogas engines not only improve waste management, but also generate an economical energy supply. – See more at: https://powergen.gepower.com/applications/biogas.
About the Solution:
For more than 80 years, GE has been recognized as a manufacturer in the development and production of gas engines for the efficient generation of power and heat. Our products are highly-developed and tested, and well-matched to each customer’s specific requirements. Essential components necessary for reliable engine operation – such as spark plugs, gas mixer, and engine controls – are developed directly in Jenbach and Waukesha. This allows GE to control the development and construction, system integration, and testing of the complete units
With a combined heat and power (CHP) system from GE, electricity and thermal energy are efficiently produced onsite for local consumption. CHP eliminates the wasteful process of purchasing electricity while separately burning fuel in an onsite boiler to produce heat. The system is further enhanced by avoiding the electricity losses that occur in the transport, transmission and distribution processes from the point of power generation to your facility.
CHP produces electrical and total (electrical + thermal) efficiencies of up to 45 percent and 95 percent, respectively. Thermal energy is released in the combustion process and can be used for preheating or generating steam, as well as a variety of process heating or cooling systems. In addition, surplus electricity can be exported to the power grid, often providing additional income. The result is a system that can provide significant efficiency, profitability and environmental advantages over individually generating heat and power for your facility.
Solution Strengths, Weaknesses and Critical Indicators
Anaerobic Digester Associated Technology:
NOTE: There are several technology types that are used as part of an integrated manure management system that includes an anaerobic digester and are not applicable to manure management in other cases. The impact of these technologies on the critical indicators are represented as those of an entire anaerobic digester system.
- Long usable life and can be run reliably
- Creates energy and generates environmental credits
- Requires proper preparation of the feedstock
- Requires other technologies for energy utilization
- Requires other technologies for digestate handling
- Proper feeding & system monitoring is required to avoid system downtime
- Proven technology for odor control, GHG reduction and pathogen reduction
- Produce electricity for on-site use and sale to the grid with a Utility Power Purchase Agreement (PPA)
- Produce heat which is used on site to increase digester influent to proper temperature
- Proven technology for use with biogas
- Require scrubbing of hydrogen sulfide from biogas for best performance
- Require regular maintenance and monitoring
- Require specialized safety equipment
- Require a utility interconnect if power is sold to the grid
GE Jenbacher engine/generators are sold internationally for use on every type of natural gas and biogas application. Known for their high electrical output efficiency compared to other engines these systems also require proper maintenance and attention to keep operating optimally. Specific training and certification is required for the control system that requires a service contract with an approved service provider. Gas quality and preconditioning is required to maximize the output and minimize downtime of these engines. GE Jenbacher dealers are found nationwide and although built in and supplied from Austria, many parts are stocked in the United States.
