“…A possible integration solution of CO2 methanation facilities in the current energy framework is by connecting them to the exhaust of diesel generators, employed as UPS (Uninterruptible Power Supply). It is feasible to partially supply the diesel group fuel flow (up to 80% (Balcu et al, 2019)) by feeding the flue gas at the exhaust of a diesel group to the methanation unit. The amount of CH4 that can be obtained represent a cleaner alternative to diesel fuel (based on equations (2) and (3)).…”

“…As a consequence of different heating values, it is demonstrated in Balcu et al (2019) that the fuel flow can be reduced with approximately 16%, while the emissions are brought down by up to 27%.…”

“…Therefore, in order to enable a slick transition towards environmentally friendly power supply also for the conventional generation, the operating traditional plants have to be upgraded. More in detail, they should comprise decarbonization technologies, facilities with improved combustion efficiency and employ alternative fuels with low carbon footprint (Balcu et al, 2019). Further, flexibility requirements (evaluated based on the mismatch between the energy demand and the continuous supply and the boundaries of the confidence interval limits) have to be satisfied to increase the high reliability of supply (Soares et al, 2017).…”

Conversion technologies able to transform renewable energy sources (RES) based electricity in gaseous fuels, which can be stored over long timeframes, represent a key focus point considering the low carbon society development. Thus, Power-to-Gas technologies emerge as a viable solution to mitigate the variability of RES power generation, enabling spatial and temporal balancing of production vs. demand mismatches. An additional benefit in this context is brought by the decarbonization facilities, employing polluting carbon dioxide (CO2) emissions and RES-based electricity to produce synthetic natural gas with high methane (CH4) concentration. The fuel obtained can be stored or injected in the gas distribution infrastructure, becoming a clean energy vector. This paper investigates the functional parameters of such technologies, aiming to comparatively analyze their suitability for further integration in hybrid and ecofriendly energy systems. Given the stability of CO2 molecule, a catalyst must be used to overcome the methanation reaction kinetics limitations. Therefore, the required conditions (in terms of pressure and temperature) for CO2 methanation reaction unfolding are analyzed first. Further, CO2 conversion rate and CH4 selectivity are investigated in order to provide a detailed comparison of available technologies in the field, addressing moreover the particularities of catalyst preparation processes. It is found that Nickel (Ni) based catalysts are performing well, achieving good performances even at atmospheric pressure and low temperatures. It is remarkable that, within a [300,500]℃ temperature range, Ni-based catalysts enable a CO2 conversion rate over 78% with a CH4 selectivity of up to 100%. Last, integration perspectives and benefits are discussed, highlighting the crucial importance of the results presented in this paper.

The paper presents an investigation on the conditions for implementing a methanation membrane decarbonator coupled to an energy installation that generates flue gases. The retention of the carbon dioxide content in the flue gases and its conversion to methane is envisaged. For start, low thermal power installations, employing natural gas as main fuel supply, are considered. Internal combustion engines (also working with natural gas fuel) are taken into account for the testing of the carbon dioxide retention process. For this, a classification of the flue gas composition by fuel categories is initially carried out. The decarbonation efficiency is defined and clarifications are made withal regarding the connection between the decarbonation installation and the energy plant. The first practical achievements are also presented, resulting from a decarbonator with a volume of 940 cm3 (having the inner diameter of 12 cm and a height of 50 cm). The results prove that the proposed solution has great potential for practical applications, further research being however necessary. In terms of operating costs (including hydrogen consumption), it is remarked that they can be reduced by exploiting the methane production and eliminating the carbon tax, extending the integration perspective form economic point of view.
