Biomass & Geothermal Solution
Maximise the Value of Every Unit of Renewable Heat.
Recover unused thermal energy from biomass boilers, economisers, steam condensers, thermal oil systems, and low-temperature geothermal brine reservoirs to generate captive electricity.
Executive Summary
Unlocking additional power from renewable thermal assets.
Biomass power plants convert renewable organic materials into heat and electricity. During this process, a considerable amount of thermal energy remains unused and is released through exhaust gases, cooling systems, and low-grade heat streams. Geothermal energy provides one of the world's most reliable renewable power sources, yet low and medium-temperature reservoirs cannot be fully utilized using conventional steam turbines.
This unused thermal energy can generate additional power.
At Datre Renewable Energy, we help biomass and geothermal operators maximize overall efficiency by converting unused thermal energy and low-temperature resources into clean, reliable power using Organic Rankine Cycle (ORC) technology—increasing electricity generation while reducing operating costs.
Heat Source Mapping
Where Does Your Plant Lose Energy?
Throughout biomass-based power generation and geothermal operations, several systems continuously reject recoverable thermal energy.
| Process Area | Typical Heat Source | Temperature Range |
|---|---|---|
| Biomass Boiler Flue Gas | Flue Gas Exhaust | 180–350°C |
| Economiser Outlet | Hot Flue Gas | 150–250°C |
| Steam Condenser Heat (Back-Pressure or CHP Systems) | Condenser & Reject Heat | 70–120°C |
| Thermal Oil System | Hot Oil Loop | 180–300°C |
| Geothermal Brine Line | Hot Geothermal Fluid | 90–220°C |
| Geothermal Separator / Reinjection | Residual Geothermal Heat | 80–160°C |
Disclaimer: The temperatures, recovery potential, and energy estimates presented on this page represent typical industry values and are provided for illustrative purposes only. Actual recoverable energy depends on plant design, operating conditions, production capacity, heat source characteristics, and overall system configuration. A detailed engineering assessment is recommended to determine the feasibility and performance of an Organic Rankine Cycle (ORC) system for your facility.
Did you know?
Depending on plant configuration, 15–30% of available thermal energy in biomass power plants remains unrecovered. In geothermal applications, ORC binary cycle technology enables efficient electricity generation from low- and medium-temperature resources (80–180°C) that conventional steam turbines cannot utilize.
Operating Impact
What Does This Mean for Your Plant?
Without recovering available thermal energy, your biomass or geothermal facility experiences lost power potential.
Lower Electrical Efficiency
Unrecovered flue gas and condenser heat reduce the total energy conversion ratio of the facility.
Reduced Power Output
Unutilized thermal potential leaves valuable megawatt-hours ungenerated every operating hour.
Underutilised Renewable Fuel
More biomass fuel or geothermal brine volume is consumed per net kWh delivered to the grid.
Higher Operating Costs
Higher specific generation expenditure per unit of electrical output degrades margins.
Lower Return on Investment
Lower net electricity sales slow the overall capital payback period of the renewable facility.
Output & Financial ROI
Typical Energy Recovery Potential
Datre manufactures standard 10 kW, 50 kW, and 500 kW ORC systems that scale modularly for biomass and geothermal power plants of any capacity.
| Process Heat Stream / Resource | Power Output |
|---|---|
| Small Biomass Unit / Economiser Stream | 10 kW – 50 kW |
| Medium Biomass Boiler / Geothermal Wellhead | 50 kW – 500 kW |
| Utility-Scale Biomass Facility / Condenser Stream | 500 kW |
| Integrated Biomass & Geothermal Power Complex | 500 kW – 5 MW+ |
Imagine the Value for a 500 kW System
Suppose a 500 kW Datre ORC System operates 8,000 hours per year, generating approximately 4,000,000 kWh (40 Lakh units) of electricity annually.
If industrial power value averages ₹7–9 per kWh, the generated captive power represents:
Instead of leaving energy unrecovered in flue gases or geothermal fluids, your facility can convert thermal energy into reliable electricity using modular Datre 10 kW, 50 kW, and 500 kW ORC units to maximize asset ROI.
