The economic feasibility and return on investment (ROI) analysis of isopentane in renewable energy systems is a critical aspect of its potential adoption. Isopentane, as a working fluid in organic Rankine cycle (ORC) systems, offers promising characteristics for low-temperature heat recovery applications. However, its economic viability must be carefully evaluated to justify implementation in renewable energy projects.

Initial capital costs for isopentane-based ORC systems can be substantial, primarily due to the specialized equipment required for handling this volatile organic compound. These costs include heat exchangers, turbines, and safety systems designed to manage the flammability risks associated with isopentane. Despite the higher upfront investment, the operational costs of isopentane systems tend to be lower compared to traditional working fluids, owing to its superior thermodynamic properties and efficiency in low-temperature applications.

The ROI for isopentane systems is heavily influenced by factors such as the scale of the project, local energy prices, and the availability of low-grade heat sources. In geothermal power plants, where isopentane can effectively utilize low-temperature brine, the ROI can be particularly attractive. Studies have shown that isopentane-based ORC systems in geothermal applications can achieve payback periods of 3-5 years, with internal rates of return (IRR) ranging from 15% to 25%, depending on site-specific conditions.

In waste heat recovery applications, such as in industrial processes or combined heat and power systems, the economic benefits of isopentane become more pronounced as the scale of heat recovery increases. For medium to large-scale installations, the improved efficiency of isopentane systems can lead to significant energy savings, translating to reduced operational costs and improved profitability over the system's lifetime.
