Hydrogen Storage
-
For US DOE, have
worked on the US DOE’s on-board hydrogen
storage project as part of its “Grand Challenge” program from 2004 to 2009.
This independent analysis project helped guiding the US DOE and
Grand Challenge participants toward promising research and development (R&D) and
commercialization pathways by evaluating the various hydrogen storage
technologies on a consistent basis. Six categories of on-board hydrogen storage
have been evaluated - compressed hydrogen, metal hydride, carbon-based
materials, chemical hydrogen storage, liquid hydrogen storage, and cryo-compressed
hydrogen storage.

Energy Storage
for Utility and Stationary Application
Lithium-ion
Battery
- For the Electric Power Research
Institute (EPRI), led a residential Lithium Ion battery backup power system
technology & cost assessment project. The assignment required
preliminary energy storage system architect design and detailed
manufacturing cost analysis on four different cathode materials (NCA, NCM,
LiFeP4, and LiMnO4). The results will help EPRI better understand the
lithium ion battery stationary application as well as system costs.
- For a major computer
manufacturer, led
an assignment to develop a Lithium Ion battery pack manufacturing cost model
for a major computer manufacturer. The assignment required to design high
volume 18650 cell manufacturing process as well as cost analysis. Results
from the analysis were used to help the client in a legal case.
Lead Acid Battery
- For a UK leading
clean energy firm, led a lead acid battery backup power system
life cycle cost assessment project. The assignment required preliminary energy
storage system architect design and detailed maintenance and operation analysis. The results will help
the client better understand the
lead acid stationary battery ownership costs.
Flow Battery
- For a flow
battery component developer (ARPA-E award winning team),
performed a bottom-up manufacturing cost analysis.
- For a MIT flow
battery start-up company (ARPA-E award winning team),
performed a bottom-up manufacturing cost analysis.
- For a UK
start-up company,
performed a cost analysis for a Pt free liquid cathode PEM fuel cell
system based on redox flow battery technology. A bottom-up manufacturing cost
model was developed which included the major stack components. The model showed
the importance of Pt free liquid cathode in reducing the system costs. The major
system cost drivers were identified. Additionally, the system cost comparisons
were included by comparing to the conventional PEM fuel cells and SOFCs.
Solar-hydrogen
Based Residential Energy Storage
- Due diligent for
a potential commercial client , the assignment evaluated the system deisgns and
manufacturing costs of the residential solar-hydrogen production systems. There
were mainly two approaches for the residential solar-hydrogen production. Option
one was the photoelectrochemical cell (PEC) which convert solar photon energy
and simultaneously electrolyze water to hydrogen and oxygen. The generated
hydrogen could be compressed and stored in the hydrogen storage tanks. Option
two used the conventional high efficient PV
to produce DC electricity and to connect directly to an electrolyzer stack,
which is the option two. We designed the system schematics and will
analyze the detailed manufacturing costs of the two systems according to the
client request.
Flying-Wheel
- Due diligent for
a potential commercial client at Austin TX, the assignment evaluated the
flying wheel system manufacturing processes. The detailed manufacturing
processes were studied via client plant visit. The results would help the
potential client improve the manufacturing cycle time and better understand the
alternative fabrication methods .
