01

Key Findings

  • 01The biogas-solar hybrid system can reduce CO2 emissions by 96.8%–97.2% compared to conventional power plants.
  • 02Selling excess electricity to the grid and green hydrogen production scenarios resulted in negative Internal Rates of Return (IRR) due to high equipment costs and low electricity prices.
  • 03A scenario involving government subsidies for municipal waste procurement showed potential for improved economic viability.
02

Application

Design takeaway

When designing renewable energy systems, thoroughly research and integrate potential government subsidies and market support mechanisms into the economic feasibility analysis.

How to apply

When proposing a new renewable energy project, conduct a thorough analysis of local government incentives, feed-in tariffs, and potential subsidies for waste or by-product utilization.

Project actions

  • 01When researching renewable energy, always look into the financial incentives available in your target region.
  • 02Consider how policy changes could impact the long-term viability of your design.
03

Method & Evidence

AimTo evaluate the economic and environmental performance of biogas-solar hybrid energy systems under different operational and financial scenarios.
MethodSimulation and comparative analysis
ProcedureA biogas-solar hybrid system was modeled using HOMER software. Various scenarios were analyzed, including a baseline, selling excess electricity to the grid, green hydrogen production, and a scenario involving government subsidies for waste procurement. Economic indicators (NPC, IRR) and environmental impact (CO2 emissions) were assessed for each scenario.
ContextRenewable energy systems development, specifically in Iran.

Strengths & Limitations

Strengths

  • +Comprehensive analysis of multiple scenarios.
  • +Quantification of both environmental and economic impacts.

Limitations

The economic viability is highly dependent on specific local market conditions and government policies, which can change.

Reliability & validity

The study's reliability is supported by the use of simulation software (HOMER) and a comparative analysis of defined scenarios. Validity is enhanced by assessing both environmental and economic metrics, though the specific economic context of Iran limits generalizability.

Think critically

To what extent can technological innovation alone drive the adoption of sustainable solutions, or is policy and economic intervention always a prerequisite?

05

Design Principles

"Sustainable energy solutions require a holistic approach that balances technological innovation with economic and policy considerations."

This research highlights a critical tension in renewable energy adoption: environmental benefits are achievable, but economic feasibility often depends on external factors like government support. Designers and engineers must consider not only the technical performance but also the market and policy landscape when developing sustainable energy solutions.

06

What This Means for Your Design

Combining biogas and solar power is great for the environment, cutting pollution by almost 97%. However, making money from it is tough unless the government helps by subsidizing the waste used for biogas.

How to use in your project

  • 1.Use this research to justify the importance of economic feasibility studies in your design project, especially when dealing with environmental solutions.
  • 2.Cite this study when discussing the impact of subsidies or market prices on the success of renewable energy technologies.

Paragraph starter

This study by Panbechi et al. (2025) demonstrates that while biogas-solar hybrid systems offer significant environmental benefits, achieving economic viability often necessitates external financial support, such as government subsidies for waste procurement, due to high initial costs and unfavorable market pricing for electricity.
