The Marnoch Thermal Energy conversion process is patented, de-risked, and proven technology that converts heat to power.
Our technology consists of a series of individual modules interconnected to a common drivetrain and transmission. This is a patented process flow step that gives our technology a major advantage.
Our technology can access thermal energy that is too low in temperature for other methods such as Organic Rankine Cycles. It will have a profound effect on the net capital cost of the unit.
Final pre-commercial prototype.
Rankine or Organic Rankine Cycles have been in use for centuries with various working fluids.
Due to the limitations of those fluids however, they cannot maintain meaningful pressures through the turbines at low temperature differentials without returning to a liquid state. This necessitates ever larger units to accommodate low pressure vapour and therefore exponentially increase capital cost per Kw, rendering them non-viable in most locales.
This also restricts their deployment options due to the enormity of their footprint relative to the application.
Our technology on the other hand has various installation options due to its modular configuration. It uses nitrogen as the working fluid and a proprietary heat transfer fluid that has a functional range of -110°C to +250°C.
Nitrogen maintains a gaseous state as low as -196°C and even under pressure of 500 Bar (7000 psi) at -100°C.
This allows extremely high pressure differentials between the modules and because of the increased density and proprietary heat exchanger configurations, allows a unit footprint up to 80% smaller than ORC units. As a result, the cost per Kw is reduced accordingly.
