“…Drawback that can provoke mismatch between power supply and demand which in turns can result in management and control problems, devices fault or, even worse, from local to global blackout. Obviously, these issues can be easily solved developing and installing large-scale energy storage plants (see, e.g., References [8][9][10][11][12][13][14][15][16]) and managing properly fossil fuels power units in order to avoid components life-time reduction (see, e.g., References [17][18][19][20][21][22][23]). Independently to these facts, wind and solar can not guarantee a both stable and programmable production as well as a simultaneous generation of electricity and heat/cold: strengths of plants working with bioenergy as input.…”

Despite biogas renewability, it is mandatory to experimentally assess its combustion products in order to measure their pollutants content. To this purpose, the Authors selected six in-operation biogas plants fed by different substrates and perform an on-site experimental campaign for measuring both biogas and engines exhausts composition. Firstly, biogas measured compositions are compared among them and with data available in literature. Then, biogas engines’ exhaust compositions are compared among them, with data available in literature and with measurements obtained from an engine characterised by the same design power but fuelled with natural gas. Finally, the Health Impact Assessment analysis is used to estimate the damage on human health caused by both biogas and natural gas engines emissions. Results show that biogas causes a damage on human health three times higher than the natural gas one. But, this approach does not consider biogas renewability. So, to include this important aspect, also an analysis which considers Global Warming categories is carried out. Results highlight that natural gas is twice harmful than biogas.

“…The mathematical model for the thermodynamic analysis of the cycles presented in Figures 1 and 2 consists of the equations for high-temperature reactor coupled with a steam turbine, gas turbine, steam regeneration, heat recovery steam generation, and a large number of minor components. An analysed cycle can be calculated by using the various methodology presented in the literature [35][36][37]. In this research study, the following equations were used.…”

The EU has implemented targets to achieve a 20% share of energy from renewable sources by 2020, and 32% by 2030. Additionally, in the EU countries by 2050, more than 80% of electrical energy should be generated using non-greenhouse gases emission technology. At the same time, energy cost remains a crucial economic issue. From a practical point of view, the most effective technology for energy conversion is based on a gas turbine combined cycle. This technology uses natural gas, crude oil or coal gasification product but in any case, generates a significant amount of toxic gases to the atmosphere. In this study, the environmentally friendly power generation system composed of a high-temperature nuclear reactor HTR integrated with gas turbine combined cycle technology and cogeneration unit is thermodynamically analysed. The proposed solution is one of the most efficient ways for energy conversion, and what is also important it can be easily integrated with HTR. The results of analysis show that it is possible to obtain for analysed cycles thermal efficiency higher than 50% which is not only much more than could be proposed by typical lignite or hard coal power plant but is also more than can be offered by nuclear technology.

“…Further, Alobaid et al [15] presented a static and dynamic simulation model of a supercritical once-through HRSG and its application to investigate the load changes and start-up processes for next generation high efficiency combined cycles. Benato et al [16,17] proposed a general and innovative procedure to simulate a combined cycle power plant and estimate its residual life.…”
