Steady-state and process modeling of a novel wind-biomass comprehensive energy system: An energy conservation, exergy and performance analysis

Thermodynamic analysis of a hybrid wind turbine and biomass gasifier for energy supply in a rural off-grid region of Nigeria

“…The comparison as presented in Table 8 reveals that the overall energy efficiency of the proposed cycle is higher than in literature [46] and lower than in literature [47]. However, the overall exergy efficiency of the present study is less than in the first three works of literature [46][47][48]. This could be a result of the wind regimes in the sites, the biomass feedstock used and the arrangement of cycles existing in their studies.…”

“…To have a better understanding of how effective the proposed hybrid wind-biomass trigeneration system in the current work is, a comparison is made between the proposed system and similar hybrid systems analysed in the open literature in terms of overall energy and exergy efficiency. The comparison as presented in Table 8 reveals that the overall energy efficiency of the proposed cycle is higher than in literature [46] and lower than in literature [47]. However, the overall exergy efficiency of the present study is less than in the first three works of literature [46][47][48].…”

Smart District Heating Networks in the Era of Energy Transformation

“…The latest generation district heating systems, conceptually shown in Figure 2, indicate the directions of development and possible pathways for decarbonising the heating sector. Advantages of low-temperature district heating (LTDH) systems include reduced heat losses in the network (efficiency), reduced greenhouse gas emissions, flexibility to use multiple renewable heat sources (including consumers), increased use of heat storage units, improved power-to-heat ratios in CHP systems and economic benefits (Bach et al, 2016;Olsthoorn, et al, 2016;Imran et al, 2017;Mathiesen et al, 2019;Wiśniewski et al, 2019;Bamisile et al, 2020;Lund et al, 2021).…”

Fractal prediction of frictional force against the interior surface of forming channel coupled with temperature in a ring die pellet machine

“…To keep the global temperature increase well below 2 °C or even 1.5 °C, if possible, as planned in the Paris Agreement, the UNEP (United Nations Environmental Program) requires most of the nations to reduce their emissions of greenhouse gases significantly. At the same time, the development of clean energy technology is urgently needed; biomass energy, for instance, is drawing global attention as a renewable, clean, and abundant energy source (Bamisile et al 2020;Khan and Ulucak 2020;Kim et al 2020;Sulaiman et al 2020;Yan et al 2020). The IEA (International Energy Agency), EIA (Energy Information Administration, USA), and many other research institutions researched the development of biomass resource technology to promote the global utilization of biomass energy (Gutierrez et al 2020;Ong and Wu 2020;Schwerz et al 2020).…”
