Toshiba Corporation (TOKYO:6502) today announced that it will supply a
first-of-a-kind supercritical CO2 turbine to a demonstration
plant being built in Texas, USA. The plant will be developed by NET
Power, LLC, a U.S. venture, together with CB&I, the most complete energy
infrastructure focused company in the world, Exelon Corporation, one of
the leading competitive energy providers in the U.S., and 8 Rivers
Capital, the inventor of the unique supercritical CO2 power
cycle that will be demonstrated by this plant. The turbine is an
essential part of the system, and Toshiba will start delivering the key
equipment in August 2016. The plant is expected to enter the
commissioning stage later in 2016.
The new supercritical CO2 power cycle system utilizes high
temperature and high pressure gas at the turbine inlet. In order to cope
with these conditions, Toshiba has utilized material specifically
developed for use in high temperature steam turbines together with
technology derived from its combustion and cooling technology used in
gas turbines. The combustor has been designed by Toshiba to cope with a
gas pressure of 300 bars, which is more than 10 times the gas pressure
utilized in conventional gas turbines.
The system utilizes supercritical CO2 as a working fluid to
produce low-cost electricity while eliminating emissions of NOx, CO2,
and other pollutants. CO2 is collected at high-pressure
without requiring additional carbon-capture equipment or processes,
enabling full carbon-capture without increasing the cost of electricity.
Since 2012, Toshiba has been developing the new turbine and combustor
for the system together with NET Power, CB&I, Exelon Corporation, and 8
Rivers Capital. The five companies have now completed major agreements
to build a 25MW gross electric (50MWt) demonstration plant in Texas.
Through the successful completion of operating tests, the demonstration
plant is intended to provide the basis for the construction of the first
295MWe full-scale commercial plant.
Toshiba and its partners will promote sales of this new power system
worldwide, with a special focus on the U.S. and the Middle East, where
there is strong demand for EOR. Going forward, Toshiba will continue to
contribute to the global environment by supplying highly efficient and
environmentally friendly power generation systems.
