Sewage Gas
Turning Wastewater into Energy
Whether you operate a wastewater treatment plant (WWTP), are a decision-maker in environmental infrastructure projects, or are part of a business with high wastewater volumes, efficient and cost-effective energy solutions are becoming increasingly important.
Our dedicated Jenbacher experts are available to provide personal consultation.
How does it work?
Jenbacher gas engines provide the solution to the rising energy costs that wastewater treatment plant (WWTP) operators have had to pay to meet their discharge permit requirements. Our gas engines efficiently and reliably convert sewage gas into electricity in plants that use anaerobic digestion for biosolids treatment.
Reference projects and operating results
Several active installations fueled by sewage gas show the generation potential of the INNIO solution.
- In Tirol, Austria, two Jenbacher gas engines, a J208 and a J312, power and heat a facility that generates energy equivalent to 120% of its demand and exports excess power to the local grid.
- Two Jenbacher J316 engines provide 1.7 MW of electrical output for a facility in Portland, Oregon. The electrical output meets about 40% of the plant’s electricity demand.
- A combined heat and power plant in Spain uses three Jenbacher J620 gas engines to produce 8 MW of power.
- Three additional Jenbacher J620 units enable a plant in Santiago Basin, Chile, to generate up to 60% of its electricity demand on site.
Benefits of CHP for wastewater treatment plants
- LEANOX controls with turbocharger bypass help maintain the air-to-gas ratio to help reduce exhaust gas emissions while supporting stable engine operation.
- A high electrical efficiency reduces the need to purchase energy from the public grid.
- A monitoring function, including remote monitoring, supports reliable operation.
- Dual-fuel operation can help balance gas production fluctuations by supplementing with natural gas as needed.
- Compact footprint helps reduce space requirements on site.
- The low-vibration engine is designed to help limit vibration transfer to surrounding structures.
