“…The graph in Figure 16 Calculated based on [158,161,162,166,168] and compared with values from many other publications [192][193][194] which have different values, however, often within the specified range, where hydrogen has very similar values in all publications and NG does not. It is essential to know that NG has so many different values in the Wobbe index that those charts could look so different in the case of the used source, where some of them [191,[195][196][197][198][199][200][201][202][203][204][205][206][207][208][209] are strongly divergent. It can strongly depend on NG's propane or butane content [210].…”

This paper presents a theoretical analysis of the selected properties of HCNG fuel calculations and a literature review of the other fuels that allow the storage of ecologically produced hydrogen. Hydrogen has the most significant CO2 reduction potential of all known fuels. However, its transmission in pure form is still problematic, and its use as a component of fuels modified by it has now become an issue of interest for researchers. Many types of hydrogen-enriched fuels have been invented. However, this article will describe the reasons why HCNG may be the hydrogen-enriched fuel of the future and why internal combustion (IC) piston engines working on two types of fuel could be the future method of using it. CO2 emissions are currently a serious problem in protecting the Earth’s natural climate. However, secondarily, power grid stabilization with a large share of electricity production from renewable energy sources must be stabilized with very flexible sources—as flexible as multi-fuel IC engines. Their use is becoming an essential element of the electricity power systems of Western countries, and there is a chance to use fuels with zero or close to zero CO2 emissions, like e-fuels and HCNG. Dual-fuel engines have become an effective way of using these types of fuels efficiently; therefore, in this article, the parameters of hydrogen-enriched fuel selected in terms of relevance to the use of IC engines are considered. Inaccuracies found in the literature analysis are discussed, and the essential properties of HCNG and its advantages over other hydrogen-rich fuels are summarized in terms of its use in dual-fuel (DF) IC engines.

Green hydrogen can be produced by consuming surplus renewable generations. It can be injected into the natural gas networks, accelerating the decarbonization of energy systems. However, with the fluctuation of renewable energies, the gas composition in the gas network may change dramatically as the hydrogen injection fluctuates. The gas interchangeability may be adversely affected. To investigate the ability to defend the fluctuated hydrogen injection, this paper proposes a gas interchangeability resilience evaluation method for hydrogen-blended integrated electricity and gas systems (H-IEGS). First, gas interchangeability resilience is defined by proposing several novel metrics. Then, A two-stage gas interchangeability management scheme is proposed to accommodate the hydrogen injections. The steady-state optimal electricity and hydrogen-gas energy flow technique is performed first to obtain the desired operating state of the H-IEGS. Then, the dynamic gas composition tracking is implemented to calculate the real-time traveling of hydrogen contents in the gas network, and evaluate the time-varying gas interchangeability metrics. Moreover, to improve the computation efficiency, a self-adaptive linearization technique is proposed and embedded in the solution process of discretized partial derivative equations. Finally, an IEEE 24 bus reliability test system and Belgium natural gas system are used to validate the proposed method.

“…Este se constituye principalmente de metano (CH 4 ) y etano (C 2 H 6 ) con cantidades menores de propano (C 3 H 8 ), butano (C 4 H 10 ), pentano (C 5 H 12 ) y otros hidrocarburos más pesados. Adicionalmente, contiene impurezas tales como dióxido de carbono (CO 2 ), agua, nitrógeno, sulfuro de hidrógeno (H 2 S), entre otros [5]. La composición puede variar según las características del yacimiento donde se encuentra confinado, pues según el contenido de hidrocarburos pesados y metano, el gas natural puede clasificarse en gas seco si el contenido de metano es mayor y en gas rico (gas húmedo) si el contenido de hidrocarburos pesados también es mayor.…”
