Description:

Topic Area 5- Advanced Brayton Cycles for Highly
Efficient Zero Emission Systems

The government seeks applications that present a plan for the development
of advanced Brayton cycle turbine concepts. The application must present
concept(s) or approach(s) that will take the state of the art Brayton Cycle
(in a combined cycle application) from today's 58 - 60 combined cycle (LHV)
efficiency to 65 - 67 equivalent efficiency or higher. The proposed
machine(s) must consider integration into advanced coal based and natural
gas based zero emission systems with the ability to attain a 60 percent
(HHV) efficiency and 75 percent (LHV) efficiency respectively (prior to
carbon separation and capture). Both systems must consider options for
zero CO2 emissions and show how this would affect the turbine design, and
operation and overall system performance. The progressive development of
other subsystems (gasifiers, air separation unit, membrane separation, fuel
cells, and etc.) will effect and should be accounted for in the performance
of these advance systems when integrated with and advanced Brayton Cycle.
Since the purpose of this topic area is to promote the development of
advanced Brayton cycles the system performance and advancement attributed
to the Brayton cycle must be clearly delineated. The concept(s) should
show how the machine would be optimized at the initial design stage for
individual fossil fuels (coal synthesis gas, H2 derived from coal, and
natural gas) or made fuel flexible. It is expected that these machines,
and associated variations, will be fully integrated depending on the
application.

The reduction of NOx emissions is an important goal for the advanced
Brayton cycle evaluated under this topic area. The base line goal for NOx
emissions is less than 3 ppm (at 15 percent O2). Brayton cycles and systems
that can efficiently surpass this limit while maintaining reasonable values
of other constraints will be considered favorably. DOE recognizes the
intrinsic conflict, in certain cases, between attaining goals for
efficiency, emissions and cost. It is also acknowledged that there are
various ways to attain DOE goals for overall system performance. A relevant
example of this conflict is the dilemma between NOx prevention, NOx control
and higher efficiency. Other conflicts can exist between efficiency and
capital cost. Successful applications will demonstrate how these conflicts
and trade-offs will be managed to develop an advanced Brayton cycle turbine
for a coal based system that meets DOE's overall goals stated above.
Applications should consider carefully the trade-off between NOx prevention
in the turbine combustor and NOx control from the system and all associated
penalties. These trade-offs should be managed to produce advanced clean
and low cost systems with high efficiencies.

Approaches that are expected to bring about these advances may include but
are not limited to: increasing the turbine rotor inlet temperature to 3100
degree F or higher, increasing pressure ratio to 35 or higher, augmentation
of the working fluid, pressure gain combustion, inter-stage reheat,
inter-cooling, recuperation, air separation integration and / or CO2
compression integration, and etc.

Work awarded as a result of successful applications will conduct system
studies with proposed advanced Brayton cycles, identify state points (mass
flow, composition, temperature and pressure) at key stages in the advanced
Brayton cycle, assess technology issues for: feasibility, R and D
requirements and cost, and provide knowledgeable input on developmental
feasibility from original equipment manufactures and / or consultants.

Application Development and Project Implementation

Applications in Topic Area 5 are expected to be system studies to identify
research and development requirements. It is expected this effort will be
between 18 and 24 months.

General Guidance for Preparing the Research and Development Implementation
Plan

A Research and Development Implementation Plan is a required deliverable in
all Phase I efforts and shall be submitted to DOE for approval within six
months of project award. This plan shall outline the project plan from
Concept to Commercial Deployment. This plan shall document alternative
concepts and configurations to be examined; proposed testing and validation
test plans, trade-off analyses and evaluation methods, criteria for
decision making processes, project milestones, go/no go decision points,
task interdependencies, critical path for product development, and other
relevant project activities. The R and D Implementation Plan must include
a budget estimate for completing Phase II and III work. (this budget is an
estimate and will not represent the final negotiated cost estimate for
Phase II and III work). Although this R and D Implementation Plan is
required in Phase I, the plan shall detail activities in Phase II and Phase
III in addition to Phase I. This plan shall be prepared using commercially
available project management software such as Microsoft Project.


General Guidance for preparing System Studies

Successful applicants will be required to follow the quality standards
provided in the most current revision of the publication "Quality
Guidelines for Energy System Studies" as prepared by NETL's Office of
Systems and Policy Support. The January 30, 2005 revision of this document
can be found as attachment A. Applicants are highly encouraged to use the
appropriate version of Aspen Plus(r) process simulation software for the
government funded system studies.
