A new white paper published by Orcan Energy examines the global potential for geothermal energy applications, the prevailing challenges to its wider adoption, the role that modular ORC technology plays in addressing these challenges.
The use of Organic Rankine Cycle (ORC) technology for power plants has significantly expanded the possibilities for geothermal power generation. In contrast to steam turbines, ORCs can exploit smaller heat sources and lower temperature levels. It operates as a closed-loop process, allowing for 100% reinjection of geothermal fluids. Temperature levels for ORC applications typically range from 100 to 180 °C.
ORC systems can be used for 100% power generation, or in scenarios where heating and power generation are coupled. Possible fluctuations in heating demand, whether seasonal or in the short-term, highlight the flexibility of modular systems.
The white paper presents several case studies on the value of modular ORC systems in addressing challenges in geothermal energy such as adapting to fluctuating heat demand or optimizing heat utilization. Since modules can operate independently, they can adjust to changing heat demand without a large penalty in efficiency.
Modular ORC systems can also be useful for different geothermal development models, such as wellhead generation. This is an excellent way to convert standalone or exploration wells into profitable assets.
