Organic Rankine Cycle (ORC)

An Organic Rankine Cycle is best suited to making electricity from low-grade heat sources, using an organic fluid to match the fluid’s properties with the temperature of the heat source.

Why We’ll Be Successful



Source Temperatures < 350ºF For sources below 350ºF, ORC is the only commercial option available

Technologies such as forward osmosis are neither commercial, nor do they match

performance, price, or availability

Examples of < 350ºF heat sources are geothermal, amine regeneration, “waste”

steam, co-produced fluids, and refinery product streams

Source Temperatures 350ºF – 550ºF In this temperature range, ORC performance matches or exceeds steam Rankine

cycles, as well as being simpler to operate and maintain

Examples of 350ºF – 550ºF heat sources are geothermal, refinery product streams,

and industrial furnace exhaust

Plant Sizes < 5000 kWe In this size range, ORC is simpler to operate and maintain than a sub-atmospheric

steam plant that requires boiler operators, water treatment, chemicals, and non-

condensable gas equipment

Air Cooled Applications Air cooling steam is a large and expensive proposition; cooling water permits are

increasingly difficult to obtain; using ORC in place of steam or to condense steam from

a backpressure steam turbogenerator at ~30 psia is a viable option

Where Does ORC Have a Technology Advantage?

ORC Development Timeline



Shaft seals Mechanical losses: ≈ 1–2%

Gearbox Mechanical losses: ≈ 4%

Couplings Inspection and maintenance costs

Lubricated bearings Mechanical losses: ≈ 2%

Oil systems Parasitic power losses: ≈ 2%

Instrumentation Separate vibration probes & proximity sensors are usually required to

monitor turbine and/or gearbox shaft vibration levels

Turbine matching Standardized turbine designs of many ORC systems are a poor match for

many applications

CN300 avoids all these problems

Conventional ORC Drawbacks Include

9–10% Power Losses



Sales Through channel partners, developers, etc.
