Solar combined with ORC

The benefit of Greenstorc technology over solar is that our systems generate electricity 24 hours per day – not just when the sun is shining or good light is present.

Yet we can effectively use photovoltaic (PV) solar as an add-on to our ORC-based systems.

Concentrated solar thermal

We utilise thermal or concentrated solar, with a Fresnel or mirror tube focusing light on a small glass tube – and driving the internal temperatures to hundreds of degrees.

Instead of the usual glycerine, we insert our own proprietary heat exchange fluid mixtures into the tubes.  These then turn ORC machines, not traditional high friction gaseous-turbines.

This makes a system like the Euro trough heat-concentrating solar system much more efficient, and therefore smaller per application. As an example, in high solar areas, we design so that less than half a hectare of space can generate 50 KW with this approach–enough to drive a small hospital with more to spare for storage in batteries, hydrogen or other technologies.
