Response Scheme

In the present scenario, world is progressing in the direction of energy crisis and severe ecological concerns due to the excessive utilization of non-renewable resources. Fossil fuel reserves are inadequate and produce hazardous geological contamination throughout the energy extraction. To meet such challenges, active amalgamation of renewable energy resources (RER) with distributed generation (DG) is the only way to progressing in future. Demand response scheme and battery storage is also essential for the reliable and consistent energy generation and efficient utilization. The role of RER in the evolution of DG is presented in this paper. The objective of this paper is to evaluate the barricades, reimbursements and influence of renewable energy based DG planning and framework. Moreover, a comparative assessment of renewable DG optimization based on optimization criteria and enhanced outcomes are evaluated for this futuristic atmospheric friendly approach.

Increasing Demand

Increasing demand for energy, limited resources of fossil fuel, as well as pollution of the environment and changes of the global climate, have raised more interest in renewable resources. Support to the use of renewable resources has become a very important part of the European Union’s policy. The use of reeds like renewable energy resources allows saving fossil fuels. This paper presents the findings on the reed resources in lakes of Latgale (region in Latvia). The investigation of reed resources shows that the resources in the region are situated in a very uneven way. The greatest amount of reed resources is concentrated in the biggest lake in Latvia - Lubana Lake as well as near it. Using direct measurement methods and metering in the distance, it was stated that the total reed resources of Lubana Lake are 8,203? 2,999 tons, occupy 882 hectares and are situated in 429 reed blocks. Summary resources of Latgale region are 19,862? 7,409 tons. The amount of heat that can be obtained using reed resources of Latgale region is equivalent to 10,543 tons of natural gas or 8,802 tons of petroleum, or 13,092- 21,348 tons of coal (it depends on the heating of coal), or 7,675 tons of fuel, or 8,712 – 12,199 tons of oil (depends on the heating of oil).

Along with the current processes of restructuring of Energy power system of Bosnia and Herzegovina, liberalization of the electricity market, and modernization of the existing power plants, Bosnia and Herzegovina must turn to the utilization of renewable resources in reason able dynamics as well. Respecting this policy, the initial Valuation of the potential of renewable erg resources in Bosnia and Herzegovina is per formed. The methodology of evaluation of wind energy utilization is presented in this paper, as well as some other aspects of utilization of the renewable energy resources in Bosnia and Herzegovina. Implementation of selected projects should improve sustainability of energy power production in Bosnia and Herzegovina, by reducing the total emission of carbon dioxide originated from energy power system of Bosnia and Herzegovina.

Abstract Rising atmospheric CO2 levels from significant imbalance between carbon emissions from fossil fuel utilization, especially for energy and chemicals, and natural carbon sequestration rates is known to drive-up the global temperatures and associated catastrophic climate changes, such as rising mean sea level, glacial melting, and extinction of ecosystems. Carbon capture and utilization techniques are necessary for transition from fossil fuel infrastructure to renewable energy resources to help delay the dangers of reaching to the point of positive feedback between carbon emissions and climate change which can drive terrestrial conditions to uninhabitable levels. CO2 captured from the atmosphere directly or from flue gases of a power plant can be recycled and transformed to CO and syngas for use as energy and value-added chemicals. Utilizing renewable energy resources to drive CO2 conversion to CO via thermochemical redox looping can provide a carbon negative renewable energy conversion pathway for sustainable energy production as well as value-added products. Substituted ferrites such as Co-ferrite, Mnferrite were found to be promising materials to aid the conversion of CO2 to CO at lower reduction temperatures. Furthermore, the conversion of these materials in the presence of Al2O3 provided hercynite cycling, which further lowered the reduction temperature. In this paper, Co-ferrite and Co-ferrite-alumina prepared via co-precipitation were investigated to understand their potential as oxygen carriers for CO2 conversion under isothermal redox looping. Isothermal reduction looping provided improved feasibility in redox conversion since it avoids the need for temperature swinging which improves thermal efficiency. These efforts alleviates the energy losses in heat recovery while also reducing thermal stresses on both the materials and the reactor. Lab-scale testing was carried out at 1673 K on these materials for extended periods and multiple cycles to gain insights into cyclic performance and the feasibility of sintering, which is a common issue in iron-oxide-based oxygen carriers. Cobalt doping provided with lowering of reduction temperature requirement at the cost of oxidation thermodynamic spontaneity that required increased oxidation temperature. At the concentrations examined, these opposing phenomenon made isothermal redox operation feasible by providing high CO yields comparable to oxygen carriers in the literature, which were operated at different temperatures for reduction and oxidation. Significantly high CO yields (∼ 750 μmol/g) were obtained from Co-ferrite isothermal redox looping. Co-ferrite-alumina provided lower CO yields compared to Co-ferrite. The oxygen storage was similar to those reported in the literature on isothermal H2O splitting, but with improved morphological stability at high temperature, especially compared to ferrite. This pathway of oxygen carrier development is considered suitable with further requirement in optimization for scaling of renewable CO2 conversion into valuable products.
