Novel solar assisted fuel driven power system

Objective



PROJECT OBJECTIVES
The objective of this project is the development and
demonstration of a novel high temperature solar process
for electricity production. The novel process comprises
solar upgrading of hydrocarbons by steam reforming in
solar specific receiver reactors and utilization of the
upgraded fuel in high efficient conversion systems as gas
turbines (GT) or fuel cells (FC). This process can be
used in small scale as a stand alone system for off-grid
markets as well as in large scale to be operated in
connection with conventional Combined-Cycle plants. The
solar reforming process has an intrinsic potential for
solar/fossil hybrid operation as well as a capability of
solar energy storage.
TECHNICAL APPROACH
The experimental solar test facility of the Weizmann
Institute of Science (WIS) will be modified and adjusted
to the new type of operation and new equipment will be
designed, purchased and installed. The volumetric
receiver-reactor (VRR) developed during the last decade
to operate in a closed loop for CO2 reforming of methane
will be modified and adjusted to work with steam and
different hydrocarbon feeds. The main changes are the
catalytic system as well as the higher operation pressure
and temperature of the VRR. The most suitable GT will be
purchased, modified and connected with the solar
reforming system. This integration includes a dual fuel
operation, combustion chamber interfacing with the
products and combination of its control to the solar
system. After completion the system consists of the solar
field, the modified loop, the improved VRR and a modified
GT and will be operated in the pilot power range of 300
kWel at the solar test facility WIS. The electricity
produced will be delivered to the grid of WIS.
The hardware part is supported and completed by studies
to enable commercialization of the new solar system and
to identify the potential of fuel cell integration.
EXPECTED ACHIEVEMENTS AND EXPLOITATION
Major technical innovations include:
- modification of a suitable GT to work with both -
synthesis-gas and fossil fuel - thus ensuring smooth and
steady power supply regardless to the intermittent nature
of solar energy,
- adjustment of the GT control and operation scheme to
operate in solar and fossil mode,
- further development of the VRR with it's solar specific
components quartz window and catalytically active
absorber to bear higher pressures and temperatures and to
operate with LPG,
- control and operation of the complete solar reforming
process.
The novel solar assisted fuel driven power system,
developed here, has not been in the market before. As
soon as the system reach operating conditions that
satisfy to the consortium, it will start with
commercialization of a small scale system. The consortium
has strong interest to include utilities, gas companies
and local industry as early as possible in exploitation
and dissemination.
