The wide-spread dependence of transportation sector on the ever-depleting and greenhouse gas emitting fossil fuels when burnt has raised considerable energy security and environmental concerns. Consequently, countries around the world have positioned biofuels as a center stage alternative to fossil fuels in their national policies to provide energy security and carbon emission control. In this regard, the paper conducts a feasibility assessment of setting-up large-scale supply chain of bioethanol (i.e., a biofuel variant) based on the regional availability of agricultural residues. Critical resources and capabilities requirements and governance attributes for bioethanol supply chains are explored using the resource-based view and institutional theory lenses. An agricultural residues (as biomass inputs) based bioethanol supply chain (BESC) model is proposed to incorporate the economic and environmental optimality considerations for an agro-climatic region. A case study of the Punjab State in India is used as an application of the proposed BESC model. Findings suggest that sustainable BESC configurations can be achieved differently for different agricultural residues. Comparative analyses, trade-off scenarios, and sustainability assessments of various agricultural residues-based BESC configurations are conducted. The policy implications of the priority areas are discussed within the bounds of India's biofuel policy. • Designed biomass-based bioethanol supply chains from a policy perspective. • Resource-based view and institutional theory are applied. • Developed large-scale supply chain model for energy security and carbon-neutrality. • Performed comparative, trade-off, and sustainability analyses for biomass types. • Priority areas for creating a nationwide bioethanol economy are identified.

This research aims to bridge the gaps to produce sustainable energy cost-effectively and technically efficient. The paper explores the techno-economic-environmental viability of photovoltaic (PV)/biomass energy potential for a rural village, Sidhwanbet, Punjab, India. The data investigation was performed by HOMER Pro v3.14 software. A hybrid renewable energy system (HRES) was designed, simulated and modelled to ensure the continuous energy supply for 770 households. The proposed optimal HRES consists of a PV module, biomass generator, converter and battery with the static specification and further improved by optimization. The optimal HRES out of the best five configurations was elected with Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) based on net present cost (NPC), cost of energy generation (COE), operating cost (ƠƇ), initial capital cost (ƗƇƇ), energy generation (ĖƓ), and a renewable fraction (Ȓϯ). The selected optimal HRES has been analyzed for economic, renewable energy and environmental aspects. The sensitivity study had performed while considering the discount and inflation rate. A simulation was performed for a 10-kW biomass generator, 1.1 kW solar array, five lithium-ion batteries, and a 3.96 kW converter. Results revealed that the PV's payback period (PBP) was 1.58 years, less than the useful life of optimal HRES. The cost of constructing an HRES for 25 years was equivalent to $21087, including initial cost, operating, replacement, and project costs. Thus, 35.6% of the necessary electricity is generated with PV and 64.4% biomass under optimal conditions for a 100% renewable energy integration. The CO 2 /year emission performance of optimal HRES is much better than Grid-only and PV-diesel generators. This technique may be used in rural regions in every other developing nation.
