And that’s a worthless comment.

This is not a reliable source to use or get information from.

As opposed to letting the superheated hot water from the well expand to steam and feeding that directly to the turbine. This is simpler but the steam is lost to the atmosphere, and as karl says, it´s not very good if the well water isn´t very hot.

So “singular binary” means the hot water heats the working fluid which goes into a single 100MW unit. Verse say 10 10 MW units.

The hot water from the ground is used to heat a second fluid from liquid to a gas. This gas is sent through a turbine to drive s generator and is then condensed back to a liquid in a closed system.
This allows low temp. or corrosive geo resources to be used.

Agreed. At least a one sentence or paragraph explaining what a singular binary geothermal plant is would truly be appreciated. I didn’t know that there could be many types of geothermal plants and I have visited at least 5 of them a decade ago. So this must be new.

I am at a loss in this article. Please explain what is a binary geothermal plant? And singular binary plant seems to be an oxymoron. Would be nice to know what these terms mean in comparison to existing geothermals.
