Biomethanation by a newly isolated Methanothermobacter sp. BS-16 for‘Power-to-Gas’ process |
| 초록 |
By increasing renewable electricity, surplus power from wind and photovoltaic generation may be used at a later time for load balancing in the energy grid. The combination of hydrogen with carbon dioxide can convert the two gases to methane using a biological methanation resulting in an interesting solution to store the electricity as CH4 and, together, upgrade biogas to higher CH4 content. Biological methanation, coupling the H2, produced by water electrolysis, with the CO2 and converting it to CH4, has been conducted by hydrogenotrophic methanogenesis. Methanothermobacter sp. BS-16 was a newly isolated strain to perform the hydrogenotrophic methanogenesis from a thermophilic anaerobic digestor in Japan. Methanothermobacter sp. BS-16 showed the excellent conversion performance on methanation (5.42 VVD) by using hydrogen and carbon dioxide with fast microbial growth rate under the optimum conditions of 60 ° C and pH 7 ~ 7.2. |
