Based on the ORC system, we are now offering pre-packaged 250 kw skid-mounted modular units.

Global Energy Infinity Turbine Series

Geothermal:  Using 190-300 deg F hot water / steam on the input side and cooling water (or a cooling tower) on the condenser end, you can generate power.  Typically this is done by drilling down until your reach suitable hot water depending on the temperature gradients in your area.  In the European geothermal model, a large diameter well/pipe is installed and then power modules are installed as the investment returns.  Depending on location and nationality of ownership, you may be able to capture a CO2 greenhouse credit which may amount to 1/3 to 1/4 in addition to the electrical power generation sales.  This only enhances the return on investment since credits can be traded or sold.  Based on preferred USA buyback rates, you may be able to generate $1.3 million in revenue per year based on a 1,000 kw system.  With a 7 percent interest loan on 10 years, you could have a nice profit and have the entire system paid for by the end of that loan term.

Waste Heat:  If you can get a liquid temperature differential of at least 125 deg F, then you may be able to produce power with the ORC system.

Microturbine:  With the heat output of 6 x Capstone C60 or C65 microturbines, you can power one 80 kw unit with the addition of a cooling tower.  The cooling tower can be geothermal cooled (ground loop) to save even more power.

Landfill and Water Treatment Flare Gas:

The technology developed using a ORC (Organic Rankine Cycle) can operate off any heat source, with a minimum of 125 deg F temperature differential between the heat source and sink.  Geothermal energy is only one potential application.  Similar systems are already in operation off heat generated from landfill flares and gas turbine exhaust.  Other applications may include using biomass as a fuel.

Oil and Gas Waste Water and Flare Gas:

The oil and gas also provides another possible application for the ORC power plant.  Because most oil and gas wells are quite deep, they are warmed by the natural thermal gradient of the earth.  In 2005 the U.S. produced over 2 billion barrels of “waste” water along with the oil and gas production, primarily from the Gulf States with temperatures high enough to produce electricity.  This hot water could be used to generate power directly, without impacting oil and gas production.
