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

22
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?

23
 Du Tremblay engine, France, 1850-56
 Ether ORC for marine steam engine
 U.S. Patent 279,270 by Frank W. Ofeldt, 1883
 Naptha ORC engine
 NREC founded, 1956; CETI founded, 1980
 1st modern ORC prototype, Harry Zvi Tabor and
Lucien Bronicki, 1961
 1st commercial ORC sale, Ormat, 1972
 CN ORC development begun, 2011
 1st CN CN300 ORC sale, 2012
 1st CN CN300 ORC shipped/started up, 2013
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

25
Sales
 Through channel partners, developers, etc.
 Direct
Licensing agreements
 Especially for high-tariff
countries
 License CN core ORC
technology to select
turbomachinery firms
 Possibly license CN ’s
last-generation ORC
technology to other firms
Growth Strategy
Worldwide ORC Plant
