The invention relates to an environmentally friendly method for generating energy from natural gas. Through the combustion of the natural gas with a mixture comprising substantially oxygen and CO2, a number of advantages are achieved with regard to the emission of CO2 and NOx. According to the invention, the CO2- rich product gas is injected into a natural gas reservoir from which natural gas has been extracted. By the underground replacement of natural gas by CO2, a pressure drop in the natural gas reservoir can be controlled, so that subsidence is prevented. Additionally, in this manner, the emission of CO2 is reduced or even wholly prevented.
L'invention concerne un procédé sans danger pour l'environnement servant à générer de l'énergie à partir de gaz naturel. La combustion du gaz naturel avec un mélange composé d'oxygène et de CO2 permet de limiter les inconvénients relatifs aux émissions de CO2 et de NOx. Ce procédé consiste à injecter le gaz obtenu riche en CO2 dans un réservoir de gaz naturel dont on a extrait du gaz naturel. Le remplacement souterrain du gaz naturel par CO2 permet de contrôler une chute de pression dans le réservoir de gaz naturel, de manière à éviter la subsidence. On peut également limiter ou même empêcher totalement l'émission de CO2.
