Research on renewable energy resources evolves as its technological diversification ensures energy liability at feasible economy. Immense demand in transportation sectors with regards to continuing growth in passenger and freight activity exhibits automotive industry plays a vital role in global warming via greenhouse gas emissions. In order to curb efforts mitigating greenhouse gases (GhG) emission via transportation, wasted heat from vehicle engine has been used as fuel. Exothermic reaction used to initiate temperature difference aids thermoelectric cooler (TEC) to convert them into electrical energy. In this study, TEC has been exercised to harvest heat exerted from chemical reaction. Influence of waste heat harvest on velocity and energy efficiency of designed lab scale thermoelectric cooler car (TECar) has been weighed along.

“…So far, the MCEC literature is not extensive even though the number of papers concerning this technology has increased in the last few years, which are mostly focused on labscale experiments using button cells (Hu et al, 2014(Hu et al, , 2016, planar single cells (Perez-Trujillo et al, 2018), and numerical models (Perez-Trujillo et al, 2018;Pérez-Trujillo et al, 2020;Barelli et al, 2020). Several studies analyze the integration of the MCC in the FC mode (MCFC) at the system level, especially as bottoming systems for biomass and gas turbine plants (Spinelli et al, 2014;Rinaldi et al, 2015;Roshandel et al, 2015) and as CO 2 removers where flue gas is fed to the OE, and then separated at the FE outlet under different operating conditions (Desideri et al, 2011(Desideri et al, , 2012, but also coupled with other technologies such as calcium looping (Della Pietra et al, 2018;De Silvestri et al, 2021). A limited number of studies (Barelli et al, 2020) have been carried out in terms of system integration analyses of MCC in the electrolysis mode (MCEC).…”

Technologies capable of efficiently exploiting unavoidable CO2 streams, have to be deeply investigated and deployed during the transition phase to achieve long-term climate neutrality targets. Among the technologies, Molten Carbonate Cells (MCC) Operating in Electrolysis Mode (MCEC) represents a promising facility to valorize CO2-rich waste streams, which are typically available in industrial plants, by their conversion into a high-value H2/CO syngas. These gaseous products can be reintegrated in a plant or reused in different applications. This study analyzes the integration of a system of the MCEC unit under different operating conditions in terms of composition, current density, and the utilization of fuels in a steam-reforming process of an Italian oil refinery via a mixed experimental-simulative approach. The aim of the current study is to assess the improvement in the overall product yield and further impacts of the MCEC unit on the plant efficiency. The results have shown that it is possible to obtain an electrochemical Specific Energy Consumption for the production of H2 of 3.24 kWh/NmH23 using the MCEC, whereby the possible integration of a 1-MWe module with a reformer of the proposed plant not only increases the hydrogen yield but also decreases the amount of fuel needed to assist the reforming reaction and separates a CO2 stream after additional purification via an oxy-fuel combustor, consequently determining lower greenhouse gases emissions.

“…Moreso, tremendous progress has been made in the energy sector in the past decades through the application of fabricated porous materials to improve the energy efficiency of buildings (Rashidi 2018), provide a source for renewable energy (Roshandel et al 2015), store and convert energy (Vekariya et al 2018;Li et al 2012), construct fuel cell electrodes (Brandon & Brett 2006;Wejrzanowski et al 2016), etc. Such great advancement has also been observed in the area of thermal management where developed porous materials are used as thermal barriers or heat exchangers (Clyne et al 2006), good heat insulating materials (Du et al 2008;Bai et al 2017), heat absorbers (Nakajima 2010), and can as well be applied to maintain a uniform temperature distribution, increase heat transfer rate, control reaction rates and improve heat flux absorption in thermal and chemical systems depending on their ultimate design (Torabi et al 2017).…”

In this research work, a modified water displacement method (MWDM) was designed and used in addition to geometry method (GM) to measure the bulk volume and then determine the bulk density values of asbestos ceiling board, cardboard paper, chalk, clay (compacted) and gypsum board that have been sun-dried to constant weight. The mean bulk densities determined by both methods were compared with the reference bulk density values of the same porous materials obtained in this work using standard test procedure in accordance with ASTM D6683-14. It was observed that, for all the tested porous materials, the percentage error in the mean bulk density values ranged from 2.3% to 49.6% when using GM and 0.9% to 5.7% by using the MWDM. Also, at 0.05 level of significance with a degree of freedom of 3, correlation coefficients of 0.7430 and 0.9955 were obtained in the cases of GM and the MWDM respectively. Again, all other analyses performed similarly revealed that the mean bulk densities obtained by the MWDM only were in close agreement with their corresponding reference values, thereby implying that apart from being cost-effective, the MWDM is better than GM in terms of accuracy, reliability, and validity. More importantly, it is noteworthy that even if the glass cylinder available for use is ungraduated, this MWDM can be employed to obtain accurate, reliable and valid bulk density values of porous materials in order to enhance thorough physical characterization, proper selection and suitable applications of such materials.
