“…The production of energy using biomass occurs by emitting CO 2 , which is reabsorbed in the regrowth cycles of the plants during the cultivation phase. Furthermore, another advantage of biomass over other renewable sources is that it is programmable and storable, reducing the potential for fluctuations in energy supply [6,[9][10][11][12].…”

“…However, the energy conversion efficiency is not optimal in these cases, causing large energy losses during the combustion process and fume exhaustion. In this context, strategies can reuse the residual heat that would potentially be lost, reintroducing it through loops into the same system or other systems requiring lower temperatures for their operation, such as with polygeneration plants [6,9,[12][13][14].…”

“…The term polygeneration describes the integration of multiple outputs in a single unity, as an energy system simultaneously providing several products such as electricity, heating, cooling, and chemical products in a decentralized way. Polygeneration presents advantages such as the reducing of GHG, a reliable energy supply, economic savings, and reduced grid losses [12,14,15]. However, polygeneration systems present the challenge of selecting the most adapted technology to be included in polygeneration plants.…”

This article aims to present an evaluation of the environmental performance of a combustion polygeneration plant fed with lignocellulosic material from cardoon (Cynara cardunculus L.) through the technique of Life Cycle Assessment (LCA). The system boundaries encompassed macro-phases of crop production, transportation, and polygeneration processes that were able to produce 100 kW of electricity, a residual thermal energy recovery system and district heating and cooling with 270 kW of heating, and a 140 kW of cooling. The LCA was performed using Cumulative Energy Demand and ReCiPe Life Cycle Impact Assessment methods through midpoint and endpoint indicators. From 2000 h/year, 165.92 GJ of electricity and 667.23 GJ of primary energy were consumed, and 32.82 tCO2eq were emitted. The rates of Greenhouse Gas (GHG) and energy demand per MJ produced were 0.08 MJSE/MJPD, 0.30 MJPE/MJPD, and 0.01 kgCO2eq/MJPD. According to the ReCiPe method, the impact categories with the highest impact loads were Terrestrial ecotoxicity (2.44%), Freshwater ecotoxicity (32.21%), Marine ecotoxicity (50.10%), Human carcinogenic toxicity (8.75%), and Human non-carcinogenic toxicity (4.76%). Comparing the same energy outputs produced by Italian power and gas grids, the proposed polygeneration plant was able to reduce primary energy demand and GHG emissions by 80 and 81%, respectively, in addition to reducing the emissions of the five main categories of impacts by between 25 and 73%.

“…It can be utilized for various energy applications that range from traditional heat generation for cooking and/or space heating to modern combined heat and power generation or biofuels production [9]. Huge amounts of biomass crop residues are generated in Egypt every year and they are mostly unexploited and discharged [10,11]. Preliminary investigations indicate that the available crop residues in Egypt can contribute considerably to achieve the renewable energy targets of Egypt Vision 2030, however, very few studies have been conducted to quantify the biomass resources [12][13][14].…”

Extensive studies are conducted to investigate the potential and techno-economic feasibility of bioenergy routes in different countries. However, limited researches have been focused on the whole national agricultural bioenergy resources in Egypt. This research provides an assessment of the potential agricultural biomass resources for electric energy production in Egypt. It provides a strategic perspective for the design of a national network of biomass power plants to utilize the spatially available agricultural residues throughout a country. A comprehensive approach is presented and is applied to Egypt. First, the approach estimates the amount, type, and characteristics of the agricultural residues in each Egyptian governorate. Then, a techno-economic appraisal for locating a set of collection stations, and installing a direct combustion biomass power plant in each governorate is conducted. SAM simulation software is used for the technical and economic appraisals, and preliminary plant capacities are estimated assuming one plant in each governorate. Secondly, a new mixed integer linear programming (MILP) model is proposed and applied to optimally design a biomass supply chain national network to maximize the overall network profit. The network is composed of the collection stations, the potential biomass power plants, and the flow distribution of residues to supply the selected plants. Results indicate that the Egyptian agricultural residue resources can produce 10 million ton/year of dry residues, generate 11 TWh/year, an average levelized cost of electricity () of 6.77 ¢/kWh, and supply about 5.5% of Egypt’s current energy needs. Moreover, the optimization results reveal that a network of 5 biomass power plants with capacities of 460 MW each should be established in Egypt. This approach is thought to be particularly suitable to other developing countries whose energy demand depends on fossil fuels and poses a heavy economic burden, and whose residues are massive, wasted, and not industrialized. The obtained results may also enrich future comparative research that studies the impact and feasibility of implementing agro-residue based biomass electric energy generation.
