evaluation of Carbon Credits earned by a solar energy park in indian conditions
The Open Fuels & Energy Science Journal, 2008Co-Authors: G N TiwariAbstract:This paper presents an analysis of Carbon Credit earning by the Solar Energy Park (SEP) at I.I.T. Delhi, New Delhi, India. The solar energy park consists of a mud house, various hybrid photovoltaic thermal (PV/T) systems with stand alone photovoltaic (SAPV) power supply. The analysis is based on experimental and theoretical annual performance of each system. The life cycle cost analysis is based on the annual performance and Carbon Credit earning of the Solar En- ergy Park. The computation of the Carbon Credit earned by the Solar Energy Park as per the norms of the Kyoto Protocol under New Delhi climate condition has also been carried out. Estimation of Carbon Credits, which will accrue to the nation if one such Solar Energy Park is built in each district/ block/Village in the country, has also been evaluated. 'Return on the investment' analysis on the basis of the life cycle cost analysis has also been made. It is seen that the cost of power gener- ated by the SAPV system (USD 0.14/kWh, USD 0.125, USD 0.116 for life cycle of 30, 40 and 50 years respectively) will be cheaper than the cost of power generated by conventional systems. It may be due to the improved technology and the economy of scale.

optimization of single channel glazed photovoltaic thermal pvt array using evolutionary algorithm ea and Carbon Credit earned by the optimized array
Energy Conversion and Management, 2015Co-Authors: Sonveer Singh, Sanjay Agrawal, Rajit GadhAbstract:Abstract In this paper, work is carried out in three steps. In the first step, optimization of single channel glazed photovoltaic thermal (SCGPVT) array has been done with an Evolutionary Algorithm (EA) keeping the overall exergy gain is an objective function of the SCGPVT array. For maximization of overall exergy gain, total seven design variables have been optimized such as length of the channel ( L ), mass flow rate of flowing fluid ( m F ), velocity of flowing fluid ( V F ), convective heat transfer coefficient through the tedlar ( U T ), overall heat transfer coefficient between solar cell to ambient through glass cover ( U SCAG ), overall back loss heat transfer coefficient from flowing fluid to ambient ( U FA ) and convective heat transfer coefficient of tedlar ( h T ). It has been observed that the instant overall exergy gain obtained from optimized system is 1.42 kW h, which is 87.86% more than the overall exergy gain of a un-optimized system given in literature. In the second step, overall exergy gain and overall thermal gain of SCGPVT array has been evaluated annually and there are 69.52% and 88.05% improvement in annual overall exergy gain and annual overall thermal gain respectively than the un-optimized system for the same input irradiance and ambient temperature. In the third step, Carbon Credit earned by the optimized SCGPVT array has also been evaluated as per norms of Kyoto Protocol Bangalore climatic conditions.

a novel software for optimizing emissions and Carbon Credit from solid waste and wastewater management
Science of The Total Environment, 2020Co-Authors: Amani Maalouf, M ElfadelAbstract:A novel model/software that assesses emissions from integrated solid waste and wastewater, SWW, management systems is presented. The main objective of SWW is to optimize emissions and Carbon Credit of complex systems. Besides its general applicability, the software covers the lack of available tools applicable in the context of developing economies. It uses Carbon Credit as a measure of environmental valuation and provides a user-friendly platform supported with several tools for technical, economic, and policy analysis as well as optimization towards minimal total emissions or costs. Finally, it encompasses a sensitivity analysis with a built-in Monte Carlo simulation to check on the variability in emissions by varying key parameters. The model/software interface was tested in the context of developed and developing economies. The results showed that best practices through material recycling, biological treatment, food waste diverted and/or energy recovery can lead to substantial savings in emissions reaching 96% (under a developing economy) and 93% (under a developed economy), with cost savings (including Carbon Credit) reaching 26% (under a developing economy) and 4% (under a developed economy), depending on the system. In closure, the results demonstrated the model applicability as a credible decision-making tool to define economically viable management alternatives with minimal environmental externalities and optimal Carbon Credit.

life cycle assessment for solid waste management in lebanon economic implications of Carbon Credit
Waste Management & Research, 2019Co-Authors: Amani Maalouf, M ElfadelAbstract:Solid waste management has witnessed much progress in recent years with considerable efforts targeting the reduction of associated impacts and Carbon emissions. Such efforts remain relatively limited in developing economies due to inefficient management practices. In this study, a life cycle assessment (LCA) approach is adopted to identify integrated systems with minimal impacts and reduced emissions in a developing context coupled with an economic valuation and sensitivity analysis to assess the effect of varying influencing parameters individually. The results showed that the highest impact arises from landfilling with minimal material recovery for recycling and composting, while incineration coupled with energy recovery contributed to the least equivalent emissions (-111% with respect to baseline scenario) at a varying cost of -70% to +93% depending on the selected technology and the value of Carbon Credit. Optimizing material recycling, composting and landfilling with energy recovery contributed to 98% savings in emissions (with respect to baseline scenario) and remained economically attractive irrespective of the Carbon Credit exchange rate of 0.5-50 US$/MTCO2E. The sensitivity analysis showed that an improvement in landfill gas collection efficiency (up to 60%) can contribute to major savings in emissions (58%). The application of the LCA-based approach supports the development of integrated viable plans while quantifying advantages and disadvantages towards decision-making and policy-planning.

thermal economic analysis of a hybrid photovoltaic thermal pvt active solar distillation system role of Carbon Credit
urban climate, 2013Co-Authors: Shiv KumarAbstract:Abstract In this paper, thermal and economic evaluation of a hybrid (PVT) active solar distillation system incorporating the effect of subsidy, tax benefit, inflation, and maintenance costs is presented for the climatic condition of New Delhi (India). The analysis is based on annualized costing and for the expected life spans of 15 and 30 years. Further CO2 emission/mitigation and revenue earned due to Carbon Credit are taken into account as per norms of Kyoto Protocol for India. Energy production factor (EPF) and life cycle conversion efficiency (LCCE) are found to be 5.9% and 14.5%, respectively, for expected life of 30 years. The energy and distillate production costs are found to be Rs. 0.85/kWh and Rs. 0.75/L, respectively, accounting the Carbon Credit earned. The cost payback period is estimated to be 4.2 years, if the distillate is sold out at the rate of Rs. 6.0/L in the local market.
