Methanation is the process that transforms hydrogen produced from a surplus of renewable electricity into methane by reacting it with the appropriate amount of CO2. In biological methanation, this conversion occurs at low temperatures due to the action of microorganisms. As part of the three-year research plan, RSE focalized on the maximization of the methane productivity in trickle-bed reactor through optimization in nutrient flow and wastewater analysis. The results demonstrate high methane purity and Methane Production Rate (MPR), near to benchmark values in scientific literature. Challenges related to component wear have been identified, but the resilience of microorganisms ensures the continuity of the plant. The future activities are focalized on further improvement of the MPR and the achievement of a long-term stabilization with the identification of an optimal configuration.<\/p>\n","protected":false},"author":93,"featured_media":0,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"tags":[1520,1305,1360,1300,1392,1307],"targets":[1304,1317],"rapporti_tipologie":[762],"class_list":["post-204811","rapporti","type-rapporti","status-publish","hentry","tag-biomethane","tag-energy-efficiency-en","tag-hydrogen","tag-industrial-sector","tag-power-to-gas-en","tag-renewable-energy-en","targets-industrial-world","targets-research","rapporti_tipologie-report-en"],"acf":{"dont_show_hompage":true,"projects":{"ID":188414,"post_author":"93","post_date":"2024-06-13 15:10:34","post_date_gmt":"2024-06-13 13:10:34","post_content":"","post_title":"Hydrogen technologies","post_excerpt":"The \u2018Hydrogen Technologies\u2019 project is a vast and ambitious research program that deals, at different levels, with multiple technologies concerning the entire hydrogen value chain, from production, to transport and storage, to end uses. \nThe research activities proposed by RSE, ENEA and CNR are very innovative in nature and focus on relatively medium to low levels of technological maturity.","post_status":"publish","comment_status":"open","ping_status":"closed","post_password":"","post_name":"hydrogen-technologies","to_ping":"","pinged":"","post_modified":"2024-07-03 10:58:19","post_modified_gmt":"2024-07-03 08:58:19","post_content_filtered":"","post_parent":0,"guid":"https:\/\/www.rse-web.it\/progetti\/hydrogen-technologies\/","menu_order":0,"post_type":"progetti","post_mime_type":"","comment_count":"0","filter":"raw"},"order_posts":"","dont_show_search":false,"related_posts":false,"show_on_slider":false,"single_post_data":{"titolo_spot":"","post_content":"
“Power to Gas” could be one of the crucial solutions for an high exploitation of the renewable energy by converting electricity into hydrogen and combining it with CO2 through the Sabatier reaction. RSE has focused its research on ex-situ biomethanation, particularly on Trickle Bed Reactors (TBR). In RSE’s “Biological Methanation” Laboratory in Milan, installed during the previous research phase (PTR 2019-2021), the first reactor (R1) was successfully inoculated, and atmospheric pressure experimentation produced methane within 70 hours of inoculation. During the actual research period (PTR 22-24), RSE has started different experimental campaigns aimed at optimizing methane production (MPR).<\/p>\n

Detailed monitoring of wastewater has provided valuable insights into key biological process parameters, including alkalinity levels, volatile fatty acids, volatile solids, total solids, and Chemical Oxygen Demand (COD). These data have allowed for the modulation of operating conditions, providing an in-depth view of the microbial population’s health inside the methanation reactor.<\/p>\n

Optimizing the supply of macronutrients and micronutrients has been a key element for the experiment’s success. The analysis has demonstrated that varying the quantities and concentrations of nutrient solutions impacts methane production, highlighting the importance of accurate control over feeding conditions to maximize reactor performance.<\/p>\n
<\/p>\n
The achieved results showed high methane purity levels and MPR values near those reported in the literature as reference performances. The experimentation will be extended with the goal of achieving even higher MPR and stabilizing its long-term value, identifying the optimal configuration for plants of this scale.<\/p>\n
