Power Generation
INNIO Group's provides advanced energy solutions leveraging biogas, landfill gas, and hydrogen for sustainable power generation. Their biogas systems convert organic waste into electricity and heat, supporting businesses with reliable and renewable energy. Cogeneration (CHP) systems achieve up to 90% efficiency by repurposing engine waste heat to produce both power and heating, significantly reducing energy costs. INNIO Group's also leads the transition to hydrogen-powered engines, offering systems that run on up to 100% hydrogen for CO2-free energy production.
Additionally, landfill gas engines utilize methane emissions from waste decomposition to generate electricity, turning waste into a resource. INNIO Group's also provides rapid-deployment mobile power solutions, ideal for emergencies or temporary energy demands. Their sewage gas engines allow wastewater treatment plants to convert sewage into electricity, reducing energy costs by up to 80%. Trigeneration systems combine cogeneration with cooling, providing heating, power, and refrigeration, further enhancing fuel efficiency and environmental benefits.
