Duryea - MODE Power System for Biogas Electricity Generation
The MODE Power System by Duryea Technologies is a biogas generator specifically designed for small and mid-sized farms and waste-water treatment plants with anaerobic digesters. This system features a compact, durable, low-maintenance engine-generator set capable of tolerating hydrogen sulfide contamination. System configurations range from 16kW to over 1MW and include options for combined heat and power (CHP) setups. The MODE's proprietary non-piston engine design, combined with two separate lubrication systems, ensures longevity and minimal maintenance. The modular nature of the system allows easy scalability and redundancy, ensuring continuous operation even during maintenance. Integrated compression technology enables efficient performance on low-methane and low-pressure biogas without the need for external compressors. Each unit includes Duryea's high-efficiency BLDC brushless generators, which simplify interconnection to the grid and enhance durability.Generating electricity from biogas can mitigate the high capital costs of an anaerobic digester. However, when selecting a genset for biogas CHP, farms face a dilemma; invest in a costly gas scrubbing system, or pay increased operations and maintenance costs. Biogas is contaminated with moisture and corrosive hydrogen sulfide, causing increased engine parts wear and necessitating frequent oil changes. Most problems occur when engine oil becomes acidified through contact with combustion gases.
Therefore, the MODE Power System employs a proprietary non-piston engine design, which includes two separate lubrication systems. The oil in the sealed combustion chamber does not migrate to other parts; the combustion process immediately consumes it. Acidification is irrelevant because the limited surfaces in contact with biogas are corrosion resistant. Importantly, the MODE's engine is comprised of less than a tenth of the parts of a conventional piston engine, making parts replacement and overhauls simple and infrequent.
The MODE's robust primary lubrication system has no exposure to combustion gases. It also doubles as a cooling system for superior digester warming via liquid-to-liquid heat exchange. Because there is no combustion contamination, this oil does not get changed outside of major service or overhauls.

The MODE (Modular On-Demand Energy) Power System is ready to meet the specific demands of electricity generation from biogas. This new engine-generator set is durable, compact and low-maintenance. The MODE Power System has a proprietary engine, tolerant of hydrogen sulfide (H2S) contamination and is designed for small and mid-sized farms and waste-water treatment plants with anaerobic digesters that wish to generate power for use on-site or sale to the grid. System configurations are available between 16kW and 1 MW+, and installable with heat exchangers for biogas CHP (combined heat and power).
