There is limited consideration on the effects of system scales and transportation processes on the economic feasibility of municipal plastic waste treatment. In this study, a techno-economic assessment framework was developed for pyrolysis-based resource recovery from non-recycled municipal plastic waste. The framework incorporates detailed transportation and process modelling with cost-benefit analysis, which enables greater assessment flexibility and accuracy and the accounting of the effects of system scale. The techno-economic feasibility of centralized large-scale and decentralized small-scale systems that recover value-added fuels (diesel and hydrogen), with and without carbon capture and storage units, were compared. The large-scale diesel system without carbon capture and storage reflected a real-world demonstrator, while other systems considered in this study were proposed alternatives to non-recycled municipal plastic waste management. Specifically, the municipal plastic waste transportation, and pyrolysis-based diesel and hydrogen production from non-recycled municipal plastic waste were modelled and simulated using ArcGIS Pro and Aspen Plus software, respectively. The data of transportation and process modelling were feed into a cost-benefit analysis to calculate the net present values of relevant developments. It was shown that only centralized large-scale diesel production, with and without carbon capture and storage, exhibited total positive net present values (£22,240,135 and £24,449,631, respectively), indicating their economic feasibility. The decentralized small-scale hydrogen production system with carbon capture and storage yielded the lowest net present value result (−£2,391) per tonne of treated non-recycled municipal plastic waste. Particularly, the production of diesel and hydrogen from non-recycled municipal plastic systems, with carbon dioxide emissions to the environment, demonstrated better economic performance than the same systems capturing and storing carbon dioxide, attributable to its higher capital and operational expenditures. Finally, sensitivity analysis revealed that the fuel sales price and OPEX had the most significant impact on the net present values.","PeriodicalId":11664,"journal":{"name":"Energy Conversion and Management","volume":"6 1","pages":""},"PeriodicalIF":10.4,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Catalytic methanation in a series of adiabatic fixed bed reactors has been implemented and substitute natural gas quality has been evaluated based on the Italian legislation. Although the updraft gasification process shows higher substitute natural gas productivity (16.3 t/h vs 13.7 t/h), better system energy efficiency (42 % vs 35 %) and energy intensity (125 vs 141 GJ/t), the levelized cost of substitute natural gas is more competitive in the chemical looping configuration due to the lower capital expenditure. Product prices of 2.26 €/kg and 1.76 €/kg have been calculated for updraft gasification and chemical looping, respectively, assuming 8 % discount rate, 80 % capacity factor, and 90 €/MWh electricity cost. Sensitivity analyses indicate that, among other parameters, the plant capacity factor and the electric power cost have a relevant impact on the final product cost. Additionally, both pathways are shown to be economically competitive with substitute natural gas production from H<ce:inf loc=\"post\">2</ce:inf>O electrolysis and CO<ce:inf loc=\"post\">2</ce:inf> capture/purchase.

We present an adsorptive-dehumidification system that utilizes a heat pipe–based desiccant-coated heat-exchanger (DCHE) module to overcome the limitations of conventional adsorptive-dehumidification systems. The DCHE-module fabrication involved the synthesis of a composite adsorbent using silica gel, binders (styrene-butadiene rubber and carboxymethyl cellulose), and a graphene solution, followed by an analysis of its physical properties. Although the composite adsorbent exhibited a 21 % lower water–vapor uptake than virgin silica gel, its thermal conductivity was approximately 25 times higher, indicating a notable advantage of the DCHE over a desiccant-packed heat exchanger (DPHE). The performance of the proposed adsorptive-dehumidification system was evaluated in terms of various operating parameters, including the regeneration inlet temperature and cycle time, with emphasis on the moisture removal rate (MRR) and cooling capacity (CC). Under specific conditions, the proposed adsorptive-dehumidification system achieved an MRR of 52.17 g/h and CC of 52.05 W. Sustainable dehumidification and regeneration was achieved by recovering heat from the heat pipes without requiring additional cooling and heating to dissipate the adsorption and desorption heat. Consequently, the maximum coefficient of performance of the system with a single DCHE module under the given operating conditions was approximately 2.60, which can be enhanced by a linear increase in dehumidification capacity with the multi-stage module design. These findings demonstrate a viable approach for developing low-energy, sustainable dehumidification systems that will ultimately contribute to the implementation of net-zero buildings.","PeriodicalId":11664,"journal":{"name":"Energy Conversion and Management","volume":"58 1","pages":""},"PeriodicalIF":10.4,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Real-time solar spectra are acquired using specialized software and remote sensing data, while the transportation and conversion of radiation energy will be solely solved at individual wavelength steps, providing the model with spectrum resolution.

It is based on a very complex object model in which the heat transfer coefficients and phase transitions of the humid air are calculated, from which only the operation of the heat exchangers is derived, and then the machines and equipment that make up the system. This approach relates, among other things, the operation of the fan inverter to the heat input and thus the amount of liquid condensed on the exchanger, which is linked to the cooling capacity of the heat pump and the refrigerant condensation and evaporation temperatures, and thus also to the compressor output. Under the conditions of a real thermal system with many interconnected components, only such an accurate model allows simulation-based optimisation of the entire system with all interconnections. All real-world units are characterised by their operating efficiency, which is also introduced into the model. The simulation model allows for not only the optimisation of operating parameters but also the selection of system components. The entire process is illustrated using the example of a heat pump supplying a drying cabinet, in order to demonstrate the correctness of the methodology on a real facility in the form of a “case study”. Optimisation was aimed at obtaining the best energy ratings for the unit and minimising drying time. Due to the multitude of parameters to be optimised and the interdependencies between them, the Taguchi method was used for the optimisation analysis. The real efficiencies for the heat pump have been introduced, focussing on the effectiveness of the heat exchanger fins and the compressor. The tests carried out after the optimisation showed a significant improvement in the coefficient of SMER (Specific Moisture Extraction Rate), which increased by almost 44 % at its peak. The factors influencing SMER underwent significant improvements, with drying time decreasing by 45 % and total energy consumption by more than 21 %.

Faced with the rapid growth of wind power and photovoltaic, the uncertainty of its power generation will increase further, and it is urgent to explore more types of flexible regulation power sources to compensate for them. The construction of pumped storage power stations among cascade reservoirs is a feasible way to expand the flexible resources of the multi-energy complementary clean energy base. However, this way makes the hydraulic and electrical connections of the upper and lower reservoirs more complicated, which brings more uncertainty to the power generation. Hence, to support the high-quality power supply, this research explores the complementary characteristics of the clean energy base building different types of pumped storage power stations, and recognizes the efficient operation intervals of the giant cascade reservoir. First, a multi-dimensional uncertainty evaluation system is proposed to elaborate on the typical output scenarios of wind power and photovoltaic in more detail. Next, based on different utilization principles of wind power and photovoltaic, the multi-energy complementary operation models of the hydropower-wind-PV hybrid system, the hydropower-wind-PV hybrid system including pump stations, and the hydropower-wind-PV hybrid system including reversible hydro units are established. Further, a multi-dimensional scenarios random combination method is applied to investigate the response relationship between the operation parameters of the key reservoir and the operation indicators of the clean energy base.

Studying the operation characteristics of multi-energy coupling system based on photocatalytic hydrogen production is beneficial to the popularization and application of this technology. A novel zero-carbon emission system that integrates freshwater, hydrogen, and electricity co-generation driven by solar energy is developed in this paper. The integrated system comprises a multistage flash desalination (MSFD) subsystem, a PWS subsystem, and a fuel cell (FC) subsystem. Considering the inherent variability and intermittency of solar energy availability, an energy storage module is strategically implemented to ensure stable and reliable system operation. The detailed model of the complete integrated system is meticulously developed and refined using Aspen Plus software. Taking the meteorological data of Hainan, China as an example, the operational parameters of the system are designed. Parametric analyses are conducted on the system’s freshwater production, hydrogen generation, and electricity output. A comprehensive evaluation is made on the thermodynamic and environmental aspects of the integrated system. The results demonstrate that the system, designed to operate continuously throughout the year, achieves this with an initial storage capacity of 85 m³ for freshwater and 130 kmol for hydrogen. Over an annual cycle, MSFD subsystem produces approximately 1812.23 m³ of freshwater, while PWS subsystem utilizes 1560.00 m³ of this freshwater to generate 2830.82 kg of hydrogen. Subsequently, FC subsystem consumes approximately 2816.63 kg of hydrogen per year to generate 43,800 kWh of electricity, while the total annual electricity consumption for the integrated system is recorded at 1995.01 kWh. The system demonstrates an average annual energy efficiency of 58.4 % and exergy efficiency of 11.2 %, illustrating both effective energy use and conversion.
