“…The carbon footprint of natural gas combustion in GTUs was calculated based on the composition and consumption of fuel per MWh [51] of energy produced [50]. The carbon footprint of hydrogen consumption was calculated based on the hydrogen consumption per MWh of energy produced [52] and on the carbon footprint of hydrogen produced by water electrolysis technology with renewable energy sources [53]. Hydrogen-containing fuel is a mixture of 80% methane and 20% hydrogen.…”

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.

“…A feasible approach is reversibly storing hydrogen in liquid or solid hydrides (hydrogen carriers) and then generating hydrogen through catalytic processes as required. Among potential hydrogen storage intermediates, ammonia (NH 3 ) is the most promising candidate due to its competitive advantages in terms of hydrogen storage capacity, zero carbon emissions, availability, cost, and safety [ 5 , 6 , 7 , 8 ].…”

“…Due to the strong, long-term demand, the infrastructure for its production, storage, and supply has been well developed. As such, compared to other zero-carbon fuels, ammonia is a widely available, practical, and affordable choice [ 8 ]. Furthermore, the extensive use of ammonia over the years has contributed to developing safety codes and standards.…”

Ammonia decomposition has attracted significant attention in recent years due to its ability to produce hydrogen without emitting carbon dioxide and the ease of ammonia storage. This paper reviews the recent developments in ammonia decomposition technologies for hydrogen production, focusing on the latest advances in catalytic materials and catalyst design, as well as the research progress in the catalytic reaction mechanism. Additionally, the paper discusses the advantages and disadvantages of each method and the importance of finding non-precious metals to reduce costs and improve efficiency. Overall, this paper provides a valuable reference for further research on ammonia decomposition for hydrogen production.

“…Hydrogen is considered an eco-friendly energy carrier because it emits only water when oxidized. − However, currently, hydrogen is produced by chemical reactions using fossil fuels (95–96% of total production), such as natural gas reforming, partial oil oxidation, and coal gasification. , Consequently, finding new means to produce hydrogen that do not rely on fossil fuels is necessary to maximize the environmental benefits . With this in mind, hydrogen production from waste has received considerable attention because the process can improve both sustainability and the diversity of hydrogen supply.…”

A comparative study to obtain a cost-competitive catalyst was performed to produce hydrogen via the high temperature water gas shift (WGS) reaction using synthesis gas (syngas) derived from waste. First, several selected active metals on Nb−CeO 2 support and preparation methods were applied to prepare highly active and stable catalysts under severe reaction conditions. Various characterization methods were employed to understand the correlation between catalytic activity and physicochemical properties of the prepared catalysts. Among the Me−Nb−CeO 2 (Me = Co, Cu, Fe, and Zn) catalysts, Co−Nb− CeO 2 showed the highest activity at a high gas hourly space velocity of 315,282 mL•g −1 •h −1 (temperature = 500 °C, X CO ≈ 84%). This was attributed to the high Brunauer−Emmett−Teller surface area and oxygen storage capacity of the Co−Nb−CeO 2 catalyst. In addition, to investigate the effect of preparation method, various methods, including coprecipitation, incipient wetness impregnation, sol−gel, and hydrothermal methods, were applied for the synthesis of the Co−Nb−CeO 2 catalyst. The Co−Nb− CeO 2 catalyst prepared using the coprecipitation method exhibited high activity without significant deactivation for 60 h. This was attributed to the high oxygen storage capacity and intimate interaction between Co and the Nb−CeO 2 support. Finally, technoeconomic analysis and environmental impact assessment were performed for the Co−Nb−CeO 2 catalysts, prepared by different preparation methods to identify the most promising catalyst for the production of hydrogen using the syngas derived from waste. By comparison with a commercial catalyst, it was shown that Co−Nb−CeO 2 synthesized using coprecipitation is a promising, costeffective, and eco-friendly catalyst with high activity.
