“…Finally, Ex H 2 (MW), Ex GT (MW), Ex ST (MW), and Ex AUX (MW) represent the exergy of hydrogen, net power generation from the gas turbine, steam turbine, and power consumed by auxiliary equipment in the whole plant. The exergy of biomass is calculated by Szargut's correlation [38], exergy of hydrogen is determined by Rant's equation [39].…”

Combined cycle, biomass calcium looping gasification is proposed for a hydrogen and electricity production (CLGCC–H) system. The process simulation Aspen Plus is used to conduct techno-economic analysis of the CLGCC–H system. The appropriate detailed models are set up for the proposed system. Furthermore, a dual fluidized bed is optimized for hydrogen production at 700 °C and 12 bar. For comparison, calcium looping gasification with the combined cycle for electricity (CLGCC) is selected with the same parameters. The system exergy and energy efficiency of CLGCC–H reached as high as 60.79% and 64.75%, while the CLGCC system had 51.22% and 54.19%. The IRR and payback period of the CLGCC–H system, based on economic data, are calculated as 17.43% and 7.35 years, respectively. However, the CLGCC system has an IRR of 11.45% and a payback period of 9.99 years, respectively. The results show that the calcium looping gasification-based hydrogen and electricity coproduction system has a promising market prospect in the near future.

“…Most of the energy produced in the world is obtained from fossil fuels and this causes the climate crisis [1,2]. For this reason, in recent years, it became increasingly important to use the currently available resources with higher efficiency and sustainability [3]. Energy efficiency can be described as the reduction of energy consumption per unit or product amount without compromising any of the comfort conditions or reducing the standard of living and quality of life.…”

Global energy crises, limited energy resources and damage to nature in energy production have pushed humanity to use energy more efficiently and renewable energy sources. In this context, the importance of implementing energy efficiency and sustainable strategies in buildings which consumes high energy, has increased. In this study, the effect of luminaires substition with more efficient ones and electricity production by renewable energy sources on efficiency, sustainability and environment was examined on a sample education building.The calculations were made according to standards and equipment supplier data. As a result of this study, it has been found that the use of high-efficiency LED lighting instead of halogen or fluorescence luminaires in the engineering faculty building and laboratory of Hitit University, will reduce the electricity consumption by 68.2%. In addition, it has been deduced that the solar energy system to be installed on the faculty’s roof, will significantly reduce CO2 emission, and has a payback period of 5.5 years. In terms of gas emissions, a roof-mounted solar energy system is 21, 45, and 32 times less hazardous to the environment than natural gas, lignite, and fuel oil, respectively.

Summary Biomass energy sources consist of materials such as wood obtained from forests, wastes from agriculture and forestry processes, and industrial, human, and animal wastes. Biogas energy is generated as a result of the anaerobic decomposition of biomass. The analysis of biogas energy potential from animal waste plays a significant role in developing countries, which involves Turkey. Therefore, the work executed in this article presents a case study for such regions. A comprehensive analysis for the production potential of biogas from the wastes of breed animals in TR83 region in Turkey, which includes the provinces of Amasya, Çorum, Samsun and Tokat is presented in this study. The number of animals and their total waste generation were determined. Then the biogas potential, along with the electricity production and the reduction of CO2 emissions, were calculated accordingly. In addition, the amount of biogas that can be produced in the TR83 region has been determined to be 151.8 M m3 per year from cattle, 6.3 M m3 per year from small cattle, and 12.9 M m3 per year from poultry. As a result, the optimal location for biogas plants based on supply chains were determined. Accordingly, the electricity potential that can be generated for the TR83 region has been determined as 49.25 MW. In addition, it has been found that approximately 19 times more carbon emissions will occur if electricity is obtained from natural gas, and approximately 34 times more emissions will be given off if it is obtained from imported coal. Ultimately, the resulting facility placement points were found to be Suluova, Çorum, Sungurlu, Bafra, Çarşamba, Vezirköprü, Erbaa, Tokat and Zile.
