I'm always astounded by the sight of that huge transcritical CO2 compressor.

Doesn't look *that* big, using the railings for scale. Or is it beyond what we immediately see in the photo?

Well I imagine it's just one compressor of many (I think it's a 4 MW rated compressor), and it's using carbon dioxide which has an exceedingly high volumetric capacity.

As somebody involved in transcritical CO2 in refrigeration (at high pressure ratios), that is one BIG TC compressor.

Aye, okay, thanks Conor. Big for its type but not 100MW big

Quite
