PARC, a Xerox company, has secured funding with the U.S. Department of
Energy's Advanced Research Projects Agency-Energy (ARPA-E) under the
Methane Observation Networks with Innovative Technology to Obtain
Reductions (MONITOR) program.
PARC will deliver very low cost printed sensor arrays to quantify and
locate methane leaks, using a variety of modified carbon nanotube (CNT)
sensors. The combined response of the sensors will provide
"fingerprints" for methane sensor and other gases. The novel approach offers a
solution to identify, quantify and locate natural gas leaks at a cost
point compatible with widespread deployment. Methane, a major component
of natural gas, is a significant greenhouse gas, with many times the
heat-trapping effect of carbon dioxide.
"We are very excited about this project," said David Schwartz, project
lead and Manager of Energy Devices and Systems at PARC. "It's a perfect
example of how printed sensor systems can provide new capabilities and
enable applications with real positive impact in the energy sector and
beyond."
The ARPA-E funded System of Printed Hybrid Intelligent Nano-Chemical
Sensors (SPHINCS) will be delivered in partnership with BP and NASA Ames
Research Center. BP will provide gas composition data, access to
production sites and other facilities, and will help develop a market
strategy to address upstream and downstream applications. The system
will build upon NASA Ames' delivered and successful demonstration of
both best-in-class electrochemical methane sensors and selective gas
sensor arrays.
PARC's methane detection system is based on sensor arrays fabricated on
polymer substrates. Each substrate contains functional printed CNT
sensor elements and supporting electronics. The CNTs are modified with
dopants, coatings, or nanoparticles, allowing them to respond
differently to different gases. Pattern matching supported by machine
learning techniques allows specific gas "fingerprints" to be discerned
from the combined sensor data. PARC's history of successfully enabling
ultra-low-cost, high-performance deployable electronic systems for
commercial applications will accelerate the development cycle for this
technology. The system will have broad applicability beyond gas wells to
pipelines, industrial and residential gas-sensing applications.
This SPHINCS project is part of a broad portfolio within the PARC Energy
Technology Program aimed at developing practical solutions to make
clean and abundant energy available across a wide range of applications.
This includes a focus on improving chemical energy storage for EVs,
consumer electronics, and electric grid support; advanced energy
conversion devices, including medium temperature fuel cells;
harsh-environment wireless sensors to improve the efficiency of coal
gasification plants; and advanced analytics to maximize energy
utilization.
