Smart Grid

Fundamental shifts in the electric power landscape are leading to tremendous business opportunities. Yet despite recent progress with demand-side services, the full potential of loads remains largely unexplored. To address the unmet need and emerging market for fast-acting demand-side services, PARC has developed a Fast Demand Response (FDR) system solution. The distributed control technology implemented in FDR allows large numbers of small loads to work in concert to provide larger aggregate energy services while minimizing inconvenience to users – enabling small, flexible loads to participate in larger markets and provide high-quality energy services.

3D Thermal Mapping

PARC is developing a portable thermal mapping system that generates detailed measurements registered on a 3D map of a building or structure, making its use ideal for energy efficiency audits.

Efficient Power Conversion

Miniaturization of power converters is important at many power levels, with applications ranging from portable electronics to photovoltaic systems. The size of power converters can be reduced by increasing the switching frequency, but with conventional techniques this results in reduced efficiency, more challenging regulation, and increased electromagnetic interference (EMI). PARC developed various innovative approaches to help miniaturize power converters without compromising on efficiency. 

Renewable Energy

PARSE - Probing Alloys for Rapid Sorting Electronchemically

Funded by ARPA-E, PARC develops light metal scrap sorting probe to reduce energy consumption, carbon emissions, and costs through identification and recycling of typically discarded scrap.

Threat-Adaptive Installation Energy Management

PARC is developing advanced energy management technologies capable of co- optimizing mission-critical energy needs with the economic value of energy assets 

Military installation energy assets have the potential to generate significant revenue in commercial electricity markets, but this is often prevented by energy security concerns. PARC is developing energy management technologies that systematically account for threat status and adapt the energy management strategy to guarantee operational needs while maximizing economic potential.

Renewable Liquid Fuels

While technologies are being pursued that produce CO2-free power, a complementary approach is to capture the CO2 emitted by existing power sources. The captured CO2 can then be sequestered underground, used for industrial processes, or used as a component of synthetic fuel. Atmospheric capture of CO2, however, is difficult due to the low atmospheric concentration of CO2 (0.039%). To address this challenge, PARC has developed technologies capable of capturing CO2 at atmospheric concentrations and delivering it at high concentrations. More recently, PARC is developing technologies capable of capturing CO2 from the sea. Seawater contains a vast resource of CO2 at higher concentration than is found in air. PARC has demonstrated the use of bipolar membrane electrodialysis to extract CO2 from seawater.

Clean Water

PARC’s breakthrough clean water platform technology, Hydrodynamic Separation (HDS), can potentially provide multiple benefits, such as: compact form factor, modular and scalable, low energy operation, low operating and maintenance costs, reduction in cap-ex, and separation of “neutrally buoyant” material. Potential applications include: wastewater (industrial and municipal) treatment; algae dewatering; process water, cooling tower, bilge water and mining water; separation of oil or other emulsions from water; distributed/on-site water treatment; and recovery of precious resources from water.
