Carlo Coltri

C arlo Coltri has a degree in Engineering management at Politecnico di Milano.
He has been contributor of JRC for UHNetwork and he is member of European Turbine network at sCO2
Working Group and member of ANIMP.
Since 2014, he published some technical articles about shale gas and potential alternatives to hydraulic
fracking.

Tsuyoshi Ishida

Tsuyoshi Ishida obtained his B.E. (1977) and his M.S. (1979) degrees from Kyoto University, Japan. He
worked for the Central Research Institute of Electric Power Industry (1980-1991). He obtained his Ph.D.
degree (1989) from Kyoto University for the dissertation entitled “Study on In-situ Stress State in Rock”.
After he worked as a faculty member at Yamaguchi University (1991-2006), where he engaged in acoustic
emission monitoring of rock fracture, he moved to Kyoto University as Professor in 2006. In Kyoto Uni-
versity, he has performed laboratory and fi eld experiments of hydraulic fracturing using water and carbon
dioxide. He has left Kyoto University in 2019 due to reaching mandatory retirement age. Now he is Pro-
fessor Emeritus of Kyoto University, and works as an adviser of OYO corporation, a visiting researcher of
Tono Research Institute of Earthquake Science, and an adviser of collaborative research between Kyoto
University and JOGMEC (Japan Oil, Gas and Metals National Corporation).

Come produrre energia elettrica dal gas

naturale senza emissioni di CO
2
L’articolo presenta una possibile sinergia tra il ciclo Allam (basato sulla CO supercritica) e l’estrazione di
2
shale gas con la stessa CO supercritica, output del ciclo Allam.
2
La combinazione delle due tecnologie potrebbe portare alla produzione di energia elettrica da gas naturale
senza emissioni di CO (grazie al conseguente sequestro di CO dell’estrazione di shale gas con CO
2

2
supercritica).
SI evidenziano alcune delle attuali problematiche relative all’estrazione con SC-CO , sottolineando anche
2
i vantaggi della CO supercritica rispetto alla fratturazione idraulica; in particolare la capacità decisamente
2
superiore di estrazione di shale gas e la possibilità di cattura della CO stessa.
