Power Generation

BIOGAS: These days everyone is talking about sustainable energy, but actions speak louder than words. Using biogas from the fermentation of organic waste, INNIO's reciprocating engines can create heat and power as a reliable energy source to power your business today, tomorrow, and in the future. How does it work? The process of biogas generation is divided into three steps: Preparation of the bio-input, fermentation, and post-treatment of the residual material. At the start, the organic material is collected in a primary pit, sterilized to remove harmful germs in case of food waste and moved to the digester. The biogas produced in the digester is collected in a gas storage tank to ensure a continuous supply of gas, independent of fluctuations in the gas production. Finally, the biogas is fed into a biogas engine. For safety reasons, the installation of a gas flare is recommended so that excess gas can be burned off in the event of excessive gas production. Jenbacher biogas generator sets are widely used by farmers and industrial users across the globe. Onsite biogas power plants can be used by businesses to supply their own electricity and heat needs (biogas cogeneration/CHP), or biogas gensets can produce electricity for future off-take to the grid. Biogas power generators can be installed inside buildings or also can be supplied as ready-to-use biogas power plant solutions in a container.

COGENERATION/CHP: Cogeneration or CHP (Combined Heat and Power) solutions from INNIO are designed to generate both heat and power increasing overall power plant efficiency up to 90% and even more. INNIO's Jenbacher CHP systems use the waste heat created during an engine’s operation to generate overall CHP plant efficiencies of more than 90%. This efficient and economical method of energy conversion achieves primary energy savings of roughly 40% by using a gas engine cogeneration system instead of separate power and heat generation equipment. Transportation and distribution losses also are reduced or eliminated as the decentralized energy supply is aligned where it is needed. INNIO Cogeneration solutions are used by our customers across the globe, powering applications in variety of economy segments, for example - industrial manufacturing, commercial, municipal applications, greenhouses and many more. Jenbacher onsite cogeneration solutions can help our customers to achieve economic targets thanks to one or several of factors, such as: decrease of Energy-related OPEX compared to centralized energy sources, or launch/extend company's operations due to new power access in energy-deficit areas, or minimize downtime thanks to improved quality of the electricity supply in regions with unstable grid infrastructure, any much more. The basic structure of INNIO's Jenbacher CHP systems includes a gas engine/gas generator unit and heat exchangers that use waste heat. A wide range of heat sources—from gas engine cooling water and oil to an air/fuel gas mixture and exhaust gas—is configured to give each individual customer the greatest possible benefit. Our cogeneration plant solutions deliver flexible power generation and a high degree of reliability and availability. Jenbacher CHP modules can be installed inside buildings or packaged into ready-to-use containerized CHP solutions. Containerized cogeneration power plants allow our customers to start using the benefits of onsite power generation quickly.

HYDROGEN FIRED POWER GENERATION: INNIO is ready for the age of hydrogen! With its potential as a CO2-free fuel source and its ability to be stored, hydrogen (H2) is an important part of the energy transition. INNIO already has 50 years of experience in converting alternative fuels into power—and more than 8,500 of our Jenbacher gas engines are operating on climate-neutral gases right now. Solutions for a CO2 Neutral Future, 3 ways to use hydrogen with Jenbacher gas engines: H2 in natural gas pipeline - As of 2022, Jenbacher gas engines can be offered with a Ready for H2 option, capable of running with up to 25% (volume) of hydrogen in the pipeline gas. As hydrogen becomes more readily available, all Ready for H2 new units and most of the currently installed Jenbacher natural gas-fueled engines can be converted to operate on 100% hydrogen. H2 locally admixed to gas engine fuel, Up to 60% (volume) hydrogen content can be used with special engine versions—and up to 100% with a dual-gas-fuel solution capable of running on 100% natural gas, 100% hydrogen or mixtures of natural gas and hydrogen. 100% H2 as gas engine fuel Jenbacher Type 4 gas engines are also available as pure H2 engines that operate only on hydrogen and are CO2-free. Today - more than 250 MW of INNIO’s installed Jenbacher fleet runs on high hydrogen fuels with up to 70% H2. 

LANDFILL GAS: Created during the decomposition of organic substances, landfill gas consists of methane, carbon dioxide, and nitrogen. The controlled collection and combustion of this problem gas is an indispensable step in the modern operation and re-cultivation of a landfill site. In addition, the high calorific value of landfill gas makes it a viable fuel for gas engines that can be effectively used for power generation. With more than 25 years of experience in the combustion of landfill gas throughout the world, INNIO's Jenbacher landfill gas engines provide an ideal solution for using your waste gas as an energy source. How does it work? Municipal waste contains about 150 to 250 kg of organic carbon per ton. These substances are biologically degradable and are converted by microorganisms into landfill gas. Stable, anaerobic methane fermentation begins one to two years after the waste is deposited in the landfill. Following a simple rule of thumb, 1 million tons of deposited municipal solid waste will produce landfill gas over a twenty-year period—an amount sufficient to fuel a gas engine capacity of 1 MW. Perforated tubes are drilled into the landfill body and interconnected by a pipe work system. Using a blower, the gas is sucked from the landfill, compressed, dried and fed into the landfill gas engine. In most cases, electrical power generated by a landfill gas power plant is fed into the public grid. Since there is no buyer for the heat output in most cases, the thermal energy could be converted into further electrical power.

MOBILE AND EMERGENCY POWER: During an emergency or a period of intense growth, you may need rapid, highly mobile power generation to quickly bridge the power gap. INNIO delivers fast, temporary expanded power through a variety of gas engine solutions. How does it work? Due to their smaller sizes and INNIO´s ability to rapidly ship, build and commission these technologies, our containerized solutions are well-suited to respond to a variety of scenarios demanding rapid power generation. The containerized portfolio delivers fast, efficient, flexible, and reliable power when and where you need it, including: helping countries reach electrification goals, providing bridge power solutions for growing demand, bringing power to remote areas, responding quickly to emergency power situations, generating backup power to support maintenance, overhauls or outages at power plants or large-scale projects/events.

OILFIELD POWER GENERATION: Because oilfield operations often unlock plentiful natural gas supplies, INNIO offers power generation solutions that put that low cost fuel to use to help power oil and gas production sites across the globe. Backed by more than a century of innovation and engine-building experience, INNIO's Waukesha and Jenbacher gas engines are ideally suited to deliver reliable and efficient performance for a variety of mobile and stationary applications – whether running on oilfield gas pulled straight from the ground, trucked-in liquid natural gas (LNG) or compressed natural gas (CNG). How it works? The field gas that is uncovered as the result of oil extraction is often wastefully flared or captured at significant expense. INNIO's fuel-flexible gas engines offer an alternative solution that turns the field gas directly into power for applications such as drill rigs, artificial lifts, pump-jacks, and worker camps.  
Rich-burn technology: Ideal for use in the most rugged environments, INNIO's Waukesha EPA-certified gas engines employ a rich-burn combustion technology for precise control of the air-fuel ratio at stoichiometric conditions. Low emissions: With the help of a three-way catalyst, rich burn engines can achieve very low exhaust gas emissions (such as NOx, CO, and THC) compared to lean burn engines. Proven reliability: Rich-burn engines offer the same reliable, continuous performance proven in gas compression applications for a variety of field environments, including: hot fuel applications, greater than 50% load step capability, and extended service intervals. High-altitude performance: While turbocharged diesel engines typically require derating above 1,500 feet (457 m), rich-burn technology offers increased flexibility with full power at altitudes up to 8,000 feet (2,438 m). Fuel flexibility: Because rich-burn engines operate with a wide knock and misfire margin, they will run at higher loads on a variety of lower quality fuels..  Lean-burn technology: For drill rig applications running LNG, INNIO's Jenbacher EPA-certified gas engines offer high-efficiency lean-burn control that is particularly well-suited to mobile oilfield applications.

SEWAGE GAS: Converting Sewage Gas to Energy in Wastewater Treatment Plants. How does it work? INNIO's 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. The process covers up to 80% of a plant’s electricity needs and makes it unnecessary to burn fossil fuels for heating. How it works? The gas produced in anaerobic digesters from municipal WWTPs generally contains 55 to 65% methane and typically has a low heating value of 500 to 600 BTU/SCF. Impressive Potential and Results.. On average, about 1 MW of electricity can be generated from biosolids for every 25-30 MGD of treated wastewater. 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 provides 120% of its energy demand and sends the excess power to the local grid. Two J316 engines provide 1.7 MW of renewable energy for a facility in Portland, Oregon. The electrical output meets about 40% of the plant’s electricity demand. A cogeneration plant in Spain uses three Jenbacher J620 gas engines to produce 8 MW of power – more than four times the norm for a standard biogas plant. Three more J620 units enable a plant in Santiago Basin, Chile, to produce up to 60% of its power with renewable electricity.

TRIGENERATION: Combined cooling, heat, and power (CCHP) systems, also called trigeneration systems, are the combination of cogeneration plants and absorption chillers. INNIO's Jenbacher gas engines offer an excellent solution for generating air conditioning and/or refrigeration. Cogeneration equipment offers high efficiency and low emissions. Absorption chillers provide an economic and environmental alternative to conventional refrigeration with compression chillers. Combining those two elements enables excellent total fuel efficiency, elimination of HCFC/CFC refrigerants, and reduced overall air emissions. How it works? Combining a cogeneration plant with an absorption refrigeration system enables the use of seasonal excess heat for cooling. Hot water from the cooling circuit of the cogeneration plant serves as drive energy for the absorption chiller. Absorption chillers produce chilled water by heating two substances (e.g., water and lithium bromide salt) that are in thermal equilibrium to separation, then reuniting them through heat removal. The heat input and removal, achieved in a vacuum at varying pressure conditions (approximately 8 mbar and approximately 70 mbar), brings the materials into imbalance, thereby forcing them to undergo desorption or absorption. Water (refrigerant) and lithium bromide salt (absorbent) are generally used for generation of chilled water in the temperature range from 6 to 12°C. Ammonia (refrigerant) and water (absorbent) are used for low temperature chilling down to -60°C.
