A US DoE-funded project is testing tiny turbines that use supercritical C02 instead of steam, that may each power 10,000 homes, and provide a breakthrough in concentrated solar power technology. (cleantechnica.com)

More specifically, it behaves as a supercritical fluid above its critical temperature (304.128 K, 30.9780 °C, 87.7604 °F)[1] and critical pressure (7.3773 MPa, 72.808 atm, 1,070.0 psi, 73.773 bar),[1] expanding to fill its container like a gas but with a density like that of a liquid.

For perspective on that pressure: a US natural gas car fills at 3,600psi (240 Bar)
