• Recent Developments on Open Thermochemical Energy Storage towards Decarbonized Building Space Heating and Cooling  
  by Asli Akyol Inada, Marzieh Rezaei, Devrim Aydin 
  Abstract: Thermal energy storage (TES) is one of the key technologies to achieve sustainability and mitigate the global warming impact. Among the all TES methods, thermochemical energy storage (TCES) presents promising features including relatively high energy density and long term heat storage potential. Accordingly, this study presents an overview with a focus on reaction and sorption-based open TCES systems. Within the study, material, reactor and process integration aspects of open TCES systems both for heating and cooling applications are evaluated. This study could provide important insights on future development of TCES materials and technologies.

• Transforming Blackwater from Multi-Storey Residential Buildings: A Sustainable and Novel Closed-Loop Approach to Reusable Water and Biogas  
  by Venkata Sai Policherla, K. Srinivas Reddy 
  Abstract: One of the most challenging issues in underdeveloped nations is the treatment of domestic blackwater. This study adopts environmentally conscious solar ETC powered MED technology to treat wastewater and biogas digester for handling human waste. This study proposes an integrated solution for a 100-family neighbourhood, processing 3,900 litres of wastewater and 160 kg of faeces each day. In April, the MED unit achieves a 49.25% recovery rate during 5 hours/day operation, yielding 13.22 tonnes of distillate annually. It also generates 1,875.37 kg methane and 55.27 tonnes of organic fertiliser each year. System performance is analysed using a MATLAB R2020a-based mathematical model.
  Keywords: domestic waste; multi-effect distillation; MED; reusable water; biogas digester; fertiliser; decentralised unit.

• Analytical Hierarchy Process and Data Envelopment Analysis for Assessment of Renewable Energy Sources  
  by Müjgan Bilge Eriş, Kemal Tepret, Hande Çavuş Arslan, Çağrı Özgün Kibiroğlu 
  Abstract: Most of the energy resources consumed today come from fossil fuels which are non-renewable and cause harmful effects on the environment. Technological improvements and increasing energy deficit have made countries to prioritize the exploration of alternative options and place greater emphasis on renewable energy resources. In this research, the analytic hierarchy process (AHP) and data envelopment analysis (DEA) techniques are used to assess the relative efficiency and generate priority rankings for a set of renewable energy resources in T
  Keywords: analytic hierarchy process; AHP; data envelopment analysis; DEA; energy efficiency; renewable energy resources; multi-criteria decision making.

• Investigation of the effect of solar energy use in buildings on reducing carbon dioxide emissions  
  by Ebru Hancioğlu 
  Abstract: The aim of this study was to examine the reduction in CO2 emissions by using solar modules. In the article, the energy analysis of Narldere Nursing Home and Rehabilitation Centre (NNHRM) an exemplary public building in Izmir, was discussed. In this study, it was determined that if 1,500 kWp PV Panels were used, approximately 63.58% of the facilitys electricity needs would be met by PV panels. It was revealed that by using the use of PV panels, an improvement of 6.98% in primary energy, 12.27% in CO2 emissions and 7.51% in PER would be achieved. The repayment period is calculated as 7.1 years.

• High-resolution Precipitation Prediction in Bangladesh via Ensemble Learning  
  by Yichen Wu, Jiaxin Yang, Lipon Chandra Das, Zhihua Zhang, M. James C. Crabbe 
  Abstract: As a developing agricultural country, Bangladesh is vulnerable to the effects of climate change, so accurate precipitation prediction is of great value to Bangladesh in achieving sustainable development. Traditional climate simulation models and prediction tools find it challenging to meet the growing needs on high spatial resolution. In this paper, we developed a XGBoost-based spatio-temporal precipitation prediction model and then generated high-resolution precipitation distribution maps in Bangladesh from 2025 to 2035, where the spatial resolution can reach 0.1
  Keywords: XGBoost model; precipitation prediction; Bangladesh.

• Estimation of the carbon footprint from road transportation: a case study  
  by Samed Aksoy, Ebru Koçak 
  Abstract: This research aims to estimate the carbon footprint of road transport in Aksaray, Turkey. The study used the Intergovernmental Panel on Climate Change tier 1 and tier 2 methodologies and found alarming increases in CO2 emissions from benzene and diesel, indicating a significant environmental impact. The results also highlight the need for ongoing monitoring and regulation of benzene and LPG emissions due to methodological differences. However, diesel emissions showed consistent assessment approaches between tier 1 and tier 2 methodologies. These findings provide valuable insights into the region's evolving carbon footprint, emphasising the need for precise methodologies for effective environmental management.

• Post-combustion CO2 capture in a CI engine using adsorbent - a numerical and experimental study  
  by Sushil Rathore, Bamunusinghe Arachchige Umesh Maduwantha, Maniarasu R, S. Murugan 
  Abstract: This research explores the feasibility of using a biomass-based adsorbent to reduce carbon dioxide (CO2) emissions from a compression ignition (CI) engine. A numerical study of counter-pressure is performed in a capture unit using permeability factors of an adsorbent. The adsorbent is kept in two positions to examine its gas adsorption performance. Numerical results ensure acceptable back pressure and superior capture efficiency. The capture unit is designed under the permissible counter-pressure limit and coupled to the exhaust of a CI engine. The adsorbent exhibited simultaneous CO, CO2, HC, and NO reduction by 6.5%, 18%, 9.8%, and 12%, respectively.
  Keywords: adsorbent; adsorption; carbon dioxide; diesel engine; greenhouse gas emissions; post-combustion capture unit.

• Spatiotemporal Distribution, Trend Forecasting, and Key Factors Analysis of CO2 Concentration in Shanghai, China  
  by Xulong Wu, Jinye Zhang, Ziyue Hu, Ruibei Liu, Hui Lv 
  Abstract: We analysed Chinas spatial and temporal CO2 concentration patterns in this study. Advanced interpolation techniques including Kriging and PCHIP were employed to process GOSAT CO2 Level 3 products to improve spatial resolution and bridge temporal gaps. Furthermore, a SARIMA(1,0,2) (1,1,2)12 model was developed to forecast CO2 concentration of Shanghai for the next year. Utilising a MLR approach (R2 = 0.995, DW = 3.356), our findings underscored the dominant roles of GDP ( = 0.814) and population ( = 0.253) in driving CO2 concentration upward in Shanghai, while NDVI ( = 0.240) emerged as a crucial factor in reducing CO2 levels.
  Keywords: CO2; Shanghai; GOSAT; SARIMA; multiple linear regression; MLR.

• Assessment of Heavy Metal Contamination and Removal using Ceratophyllum demersum L.: A Case Study  
  by Aybike Gül Karao?lu, Mehmet Kobya, Aysegul Y.G. Kara, Esra Me?e, Melike Tepe 
  Abstract: Assessment of heavy metal contamination in aquatic ecosystems continues to remain challenging. In this regard, Ceratophyllum demersum L. (C. demersum L.) is a common species found in rivers and can be used as a bioindicator to see the accumulation of heavy metals in the plant body. In this study, we aimed to investigate the accumulation of toxic metals and their effects on photosynthetic pigment content in plants for different seasons. The highest metal accumulations were observed in October 2019. The mean boron concentrations were 399 mg/kg in October 2019, while they were measured as 163 mg/kg in July 2020, most probably due to the decreasing agricultural activities in the studied area. However, the highest metal concentrations (aluminium 3941 mg/kg and iron 5161 mg/kg) were measured in July 2010. Moreover, the pigment content values were decreased with the increasing metal concentration in plants. The highest pigment content of 4.7
