Wastewater contains considerable amounts of thermal energy. Heat recovery from wastewater in buildings could supply cities with an additional source renewable However, variations temperature influence the performance treatment plant. Thus, is negatively affected by heat upstream Therefore, it necessary to develop more accurate models variations. In this work, a computational model based on artificial neural network (ANN) proposed calculate plant influent concerning ambient temperature,...

New concepts and technologies are needed to upgrade conventional energy systems cope with environmental challenges. However, while emerging new may serve improve efficiency at the local level, they might also have disruptive effects system level. This paper investigates potentially impacts of upscaling wastewater heat recovery building level on performance treatment district heating in Stockholm. A hybrid model based data-driven process-driven mathematical models was developed simulate...

Abstract The concept of symbiosis, a mutually beneficial relationship, can be applied to food and energy systems. Greenhouse systems biogas plants are interesting technologies for food–energy because both usually based in rural areas offer opportunities the exchange materials (e.g., biomass waste from greenhouse as input plants) (heat co‐generation heating greenhouses). In this paper, focus lies on manure resources Switzerland, amounts high currently largely underused. We provide spatial...

The municipal solid waste (MSW) remains a great challenge in most cities of developing countries, as the majority generated is either not collected or dumped open uncontrolled non-engineered landfill sites, creating significant pollution due to leakage leachate surrounding environment. In complete transition zero-landfill scenario less likely happen near future various socio-economic challenges. Therefore, existing landfills countries need holistic management thinking with more efforts on...

The aim of this study is to couple molten carbonate fuel cell (MCFC) stack with integrated gasification combined cycle fed by refinery residues, remove CO2 from gas turbine exhaust gases that have emission rate 14,200 ton/year. By applying multi-objective optimisation (MOO) using genetic algorithm, the optimal values operating load and corresponding objective functions are obtained. MOO MCFC system regarding two scenarios performed. first scenario minimisation cost electricity (COE) rate....

This article deals with ongoing attempts to recover heat and greywater at property level, based on an in-depth study of Stockholm, Sweden. We explore different socio-technical development paths from now up until 2050 using a novel combination on-property technology case-studies, actor studies system-level scenario evaluation, Artificial Neural Networks modelling. Our results show that the more conservative scenarios work in favour large-scale actors while radical benefit owners. However, we...

Carbon emissions significantly contribute to global warming, amplifying the occurrence of extreme weather events and negatively impacting overall environmental transformation. In line with commitment combat climate change through Paris Agreement (COP21), European Union (EU) has formulated strategies aimed at achieving neutrality by 2050. To achieve this goal, EU member states focus on developing long-term national (NLTSs) implementing local plans reduce greenhouse gas (GHG) in alignment...

This paper proposes a multiphysics simulation structure for predicting Li-ion batteries’ useful life by consolidating battery cell electrochemical and thermal-aging models into the electrical domain of PV-battery standalone systems. model can consider effect operating conditions at system level, such as charge/discharge patterns energy management strategies, to evaluate capacity fade level. The proposed is validated using experimental observations with RRMSE 1.1%. Results show that bank...
