6. The little engine that could. GE launched " the world's
first " two-stage turbocharged gas engine, and it is initially applying the
technology to its Jenbacher J624 engine (shown here). The company
claims that an advanced boost pressure increases the 24-cyclinder gas
engine's output by nearly 10%-from 4 MW to 4.4 MW-and its electrical
efficiency to 46.5%. Courtesy: GE
MHI, Foster Wheeler to Support FEED for UK CCS Project.
A consortium of Mitsubishi Heavy Industries (MHI) and Foster
Wheeler Energy Ltd. on August 5 announced that it had received
an order from E.ON UK to support the front-end engineering design
(FEED) for a post-combustion carbon dioxide (CO2
) capture
plant proposed as part of E.ON's planned 1,600-MW supercritical
coal-fired power plant in Kingsnorth, Kent. The proposed project
is one of two facilities competing for UK government funds to
build an industrial-scale carbon capture and storage (CCS) demonstration
plant. It will use MHI's KM-CDR Process, a CO2
ery technology, to separate, recover, and compress CO2 from the
recovsaid
Prady Iyyanki, CEO of the gas engines division of GE Power
and Water, who called the technology " game-changing. " In
addition to the higher charging pressure, the technology also
significantly improves the power density of the engine, allowing
it to run beyond 22 bar brake mean effective pressure-the
average cylinder pressure expressed in units of pressure, which
is calculated from the engine power output, displacement, and
rotational speed.
Applications for the new gas engine include independent power
producers, CHP, trigeneration, and special applications using
natural gas fuel-as well as a range of non-natural gas fuels,
said GE. The new engine will be available around the world by
the summer of 2011.
coal-fired flue gas and store it within a depleted gas reservoir in
the North Sea. The overall FEED activities are expected to further
develop the project and will involve engineering and design studies.
It will be followed by the selection of a competition winner
by the UK government.
DOE Funds FutureGen 2.0. Also on August 5, U.S. Energy
Secretary Steven Chu announced the award of $1 billion in American
Recovery and Reinvestment Act funding to the FutureGen
Alliance, Ameren Energy Resources, Babcock & Wilcox, and Air Liquide
Process & Construction Inc. to build FutureGen 2.0. The new
project will repower Ameren's 200-MW Meredosia Unit 4, located
near Meredosia, in western Illinois, with advanced oxycombustion
technology, which combusts coal in oxygen rather than air.
" We now have tapped into what I think is the cutting edge
of coal research, " Sen. Dick Durbin, D-Ill., said when announcing
the project in Washington with Chu. The project will be 80%
funded by Recovery Act money approved last year, and construction
will begin in the spring, Durbin said. Durbin estimated the
cost of the repowering work at Ameren's Meredosia plant at $737
million. The proposal also called for a 175-mile pipeline that
moved the collected CO2
to underground storage facilities at the
400-acre site at Mattoon, but Coles County recently declined to
participate in the DOE's revamped project.

mens Energy on August 2 said it had been awarded a front-end
engineering design contract by Summit Texas Clean Energy LLC
to provide coal gasification and power block technology for the
Texas Clean Energy Project. The new 400-MW polygeneration integrated
gasification combined cycle (IGCC) project planned near
Odessa, Texas, will use coal as its feedstock. The plant will capture
90% of its CO2
emissions for enhanced oil recovery in the
West Texas area.
Siemens will deliver the gasification island technology, which
will include two SFG-500 gasifiers. The power block will be based
on an SGT6-5000F gas turbine modified to operate on high hydrogen
syngas, which will allow the plant to have a very high
carbon capture rate of about 3 million tons/year. The power block
will include a Siemens SST-900RH steam turbine, air-cooled generators,
and SPPA-T3000 controls. Siemens will be working with
Fluor Corp. and Linde during the project's FEED. The project has
received a $350 million award under the U.S. Department of Energy's
Clean Coal Power Initiative, Round 3 to demonstrate the
commercial integration of large-scale IGCC with CO2
capture and
geologic storage.
Westinghouse to Dismantle Spanish Nuclear Reactor.
Westinghouse Electric Co. on July 28 said it has been awarded a
contract by Enresa (Empresa Nacional de Residuos Radiactivos) to
dismantle the reactor vessel internals at the Jose Cabrera Nuclear
Power Station, also known as Zorita, located near Madrid, Spain.
The contract includes the up-front engineering studies as well as
plant modifications, equipment supply, and loading of primary
