Title: | Renewable natural gas as climate-neutral energy carrier? | Authors: | van der Zwaan, Bob Detz, Remko Meulendijks, Nicole BUSKENS, Pascal |
Issue Date: | 2022 | Publisher: | ELSEVIER SCI LTD | Source: | Fuel, 311 (Art N° 122547) | Abstract: | Natural gas is a potent greenhouse gas but remains an attractive energy resource for a good number of reasons. Because complementing the use of natural gas with carbon dioxide capture and storage yields several drawbacks, producing synthetic natural gas instead could be an interesting alternative. Methanation is an established and well-known process, and with atmospheric carbon dioxide as input it could deliver a climate-neutral energy carrier, which we refer to as renewable natural gas. At present, however, methanation is exceedingly costly. In this paper we try to answer two main questions: (I) can innovative methanation such as based on sunlightpowered plasmon catalysis compete with more conventional methanation options using the Sabatier reaction in e.g. adiabatic fixed-bed processes; (II) can these two alternatives ever compete with abundantly available natural gas? Under realistic assumptions for technology learning, we find that innovative methanation technology could compete with conventional methanation systems sometime between 2032 and 2039 in our base case scenario. The required learning investments for the innovative option would amount to about 80 M(sic), spent on an installed capacity of around 750 MW. We also conclude that the levelized cost of methane remains dominated by the cost of hydrogen until at least the middle of the century. Methanation could in principle compete with natural gas by 2050, but only if a carbon tax is levied of at least 270 (sic)/tCO(2). | Notes: | van der Zwaan, B (corresponding author), Netherlands Org Appl Sci Res TNO, Amsterdam, Netherlands.; van der Zwaan, B (corresponding author), Univ Amsterdam, Fac Sci HIMS & IAS, Amsterdam, Netherlands.; van der Zwaan, B (corresponding author), Johns Hopkins Univ, Sch Adv Int Studies SAIS, Bologna, Italy. bob.vanderzwaan@tno.nl |
