Summary
This summary is machine-generated.Pine needles can be gasified for green electricity and biochar, reducing fire risks and emissions. A 250-kW plant offers economic viability, especially with subsidies, and significantly cuts carbon dioxide (CO2) emissions.
Area Of Science
- Renewable Energy Engineering
- Environmental Science
- Supply Chain Management
Background
- Pine needles are abundant globally but pose fire risks, especially in dry climates like Uttarakhand, India.
- Annual forest fires in Uttarakhand emit substantial amounts of carbon dioxide (CO2) equivalent.
- Pine needles present an opportunity for sustainable energy production and waste reduction.
Purpose Of The Study
- To assess the feasibility of using pine needles for green electricity and biochar production via gasification.
- To design and evaluate a gasification-based supply chain for pine needles in Almora District, Uttarakhand.
- To analyze the economic and environmental performance of various pine needle gasification plant capacities.
Main Methods
- Modeling a gasification supply chain for pine needles, considering losses, site selection, and transportation.
- Evaluating ten plant capacity scenarios ranging from 25 to 250 kW.
- Conducting economic analysis (discounted payback period, internal rate of return, net present value) and emission analysis.
Main Results
- The 250-kW plant scenario showed the most favorable economics, with a discounted payback period of 3.93 years (1.30 years with subsidies).
- Economic viability was significantly enhanced by government subsidies, improving IRR to 69% and NPV to 916.17 million INR.
- Gasification plants could reduce annual CO2 equivalent emissions by 44.63–46.16 million kg and meet ~5.5% of Almora's electricity demand.
Conclusions
- Pine needle gasification is a viable solution for green energy production and waste management.
- The economic feasibility of pine needle gasification is strongly influenced by plant scale and government support.
- This approach contributes to climate action, sustainable infrastructure, and improved health outcomes by reducing emissions and fire risks.

A three-phase AC generator has a rotor with a rotating magnet placed within the stator mounted with the stationary three-phase winding to generate three-phase voltages via mutual induction. These windings are evenly distributed around the inner circumference of the stator and are arranged 120 electrical degrees apart. Three-phase stator windings consist of three separate coils or groups of coils, known as phases, each connected in Y (star) configuration or Delta configuration.

Power system distribution involves delivering electrical energy from power plants to consumers through a network of transmission and distribution systems. The process begins at power plants, where energy from coal, gas, nuclear, water, and wind is converted into electrical energy. These plants use three-phase generators, typically rated between 50 to 1300 MVA, with terminal voltages ranging from a few kV to 20 kV, depending on the size and age of the units.

Generator voltage control is crucial for maintaining the stable operation of synchronous generators and wind turbines. In older models, a DC generator driven by the rotor delivers DC power to the rotor's field winding, and the power is transferred through slip rings and brushes. In the latest models, static or brushless exciters are used. Static exciters rectify AC power from the generator terminals and then transfer the DC power directly to the rotor. Brushless exciters, on the other hand,...
