Biomass-based cogeneration (CHP) is one of the most efficient uses of bioenergy – simultaneously producing heat and electricity with thermal efficiencies up to 85%. But operating these systems optimally is complex, especially when feedstock quality, demand, and combustion dynamics are constantly shifting.
AI brings a new level of precision and adaptability to biomass CHP management – improving efficiency from fuel input to energy dispatch.
From real-time load balancing to combustion tuning and predictive maintenance, AI is transforming biomass cogeneration into a grid-responsive, low-emission powerhouse.
