Gas turbine installations (GTIs) are widely used to generate electrical and thermal energy, mainly by burning gaseous fuels. With the development of hydrogen energy technology, a current area of particular interest is the use of GTIs to burn hydrogen. In order to assess the prospects of using GTIs in this way, it is necessary to understand the carbon emissions of gas turbines within the larger context of the entire hydrogen life cycle and its carbon footprint. The article provides an overview of results from previously published studies on life cycle assessment (LCA) of complex technical devices associated with the production and consumption of fuel and energy, which are most similar to GTIs when it comes to the complexity of LCA. The subject of analysis was a set of GTIs located in Russia with a capacity of 16 MW. An assessment of greenhouse gas (GHG) emissions per MWh of electricity produced showed that at different stages of the GTI life cycle, the total carbon footprint was 198.1–604.3 kg CO2-eq., of which more than 99% came from GTI operation. Greenhouse gas emissions from the production and end-of-life management stages are significantly lower for GTIs compared to those for other complex technical devices used to generate electricity. This is an indicator of the strong prospects for the future use of GTIs.

The availability of water on Earth's surface is influenced by rainfall and climate in a particular region. Water is a basic necessity for human beings and is used for various daily life purposes. One of these purposes is irrigation in agricultural lands. The agricultural sector has traditionally relied on the availability of water from rainfall and the suitability of the climate. Climate factors include air temperature, humidity, sunlight intensity, and wind speed. This research aims to determine the impact of rainfall and climate conditions on agricultural lands. The study utilizes descriptive analysis of climate data and its influence on agricultural lands. The research findings reveal that the average monthly rainfall in Kediri district, West Lombok Regency, is approximately 222.75 mm. The average temperature is 26.7 degrees Celsius, with an average humidity of 84.5%, average sunlight intensity of 65.9%, and an average wind speed of 3.1 knots. These rainfall and climate conditions can affect water availability, soil microbe growth, plant photosynthesis processes, and plant pollination processes in agricultural lands.

“…Therefore, the demand for stationary fuel cell systems for buildings is increasing worldwide. Also, the electricity output, durability, system size, operation, installation, and operation costs of fuel cell systems are becoming competitive [5,6]. In particular, the efficiency of a fuel processor and fuel cell combined system is mainly affected by the fuel processor efficiency [7,8].…”

To increase the efficiency of a fuel processor and HT-PEMFC (high temperature-proton exchange membrane fuel cell) combined system, it is essential to improve the efficiency of the fuel processor. In this research, the fuel processor was simulated by the Aspen Hysys® simulator, and the effect of the various operating conditions on the total efficiency was investigated. The thermal efficiency of the fuel processor increased as the temperature and S/C (steam-to-carbon) ratio increased, and the efficiency was higher at an S/C ratio of 3 than at an S/C of 4 with a reformer temperature of 700 °C and higher. Under the selected operating conditions of the fuel processor, the recycling of unreacted hydrogen from the anode off-gas (AOG) of the HT-PEMFC improved the overall efficiency of the combined fuel processor and HT-PEMFC by a factor of 1.28. The operating conditions where the AOG supplied more heat than was required for fuel processor operation were excluded. The high-efficiency operating conditions of the fuel cell system were proposed with the target of 5 kW of output as the capacity of the household HT-PEMFC.
