Un partenariat entre l’universit\u00e9 de Chiba (Banlieue est de Tokyo) et la compagnie Tokyo Gaz\u00a0 a donn\u00e9 naissance \u00e0 un projet \u00e9tonnant : produire des tomates \u00e0 partir du CO2 g\u00e9n\u00e9r\u00e9 lors de la production d’hydrog\u00e8ne.<\/p>\n

Ce projet repose sur un principe simple : La station-service \u00e0 hydrog\u00e8ne de Haneda [1] (Sud de Tokyo, proche de l’a\u00e9roport international du m\u00eame nom) g\u00e9n\u00e8re du CO2. Celui-ci est liqu\u00e9fi\u00e9 [2], puis transport\u00e9 dans des cylindres de 160 kg vers le d\u00e9partement d’horticulture de l’universit\u00e9 de Chiba, \u00e0 55 km de Haneda. La production de CO2 est de 320 kg par mois.<\/p>\n

Les serres de tomates, situ\u00e9es sur le campus du Center for Environment, Health and Field Science, University of Chiba, font partie d’une installation de culture de 1000 m2. Le CO2 y est utilis\u00e9 pour augmenter artificiellement la concentration atmosph\u00e9rique de ce gaz dans les serres : Se situant habituellement aux alentours de 400 ppm, cet apport plus que double celle-ci, puisque les concentrations relev\u00e9es sont de l’ordre de 1000 ppm.<\/p>\n

La croissance des tomates d\u00e9pend de la concentration de CO2 dans l’atmosph\u00e8re. La r\u00e9colte issue des serres \u00e0 haute concentration de CO2 est donc plus abondante que dans des conditions de culture habituelles. Ainsi, pour une production de 40 kg de tomates par m2 par an dans des conditions normales, l’apport de CO2 permet lui d’atteindre 50 kg de tomates par m2 par an, tomates au go\u00fbt fort et sucr\u00e9.<\/p>\n

Ces r\u00e9sultats sont le fruit de recherches pr\u00e9c\u00e9dentes, le projet d\u00e9butera en d\u00e9cembre 2011, pour une dur\u00e9e d’un an, avec des r\u00e9coltes trimestrielles. Tokyo Gaz \u00e9tudie maintenant la possibilit\u00e9 d’installer des serres \u00e0 proximit\u00e9 de la station hydrog\u00e8ne.<\/p>\n
