Project Status

Project Update

This project kicked-off in July 2022. Since then the project team has begun material manufacturing for a custom multi-layered piezoelectric capacitor and procuring all necessary components through suppliers and in-house manufacturing within geometric, mechanical, and electrical specifications.

The Issue

The cost of lithium batteries has fallen dramatically in the past decade. For a 4-hour, grid-tied solution, the levelized cost is approaching $0.20/kilowatt-hour (kWh). However, single-use batteries can be 1,000 times more expensive given the need for replacement. Throw-away batteries remain the most expensive source of power in the world today. Consequently, battery devices are extremely low power, typically drawing <1 milliwatt (mW) on average to reduce the burden of replacements or recharging. The poor economics limit the use of battery devices at scale (for instance, large-scale infrastructure monitoring). Alternatively, energy harvesting could support numerous and more powerful devices while generating cost savings over time.

Project Innovation

This project will deploy a novel auto-modulating power source (AMPS) device and demonstrate water and cost savings across approximately 150 affordable housing units in Los Angeles. The bill savings from water and avoidance of lithium battery replacements will be scalable to over two-thirds of California households to meet Assembly Bill 758 mandates and other municipal green initiatives.The target application is multi-family housing where a majority of water meters are read bimonthly and tenants overpay regardless of usage.

Project Goals

Validate proof of customer benefits with up to 34% bill savings on water.
Help monitor water use for leakage detection and mitigate inadvertent water use.
Improve water quality with autonomous sensing, tracking, and reporting of contamination.
Provide service and emergency shutoff features to mitigate expensive plumbing contractor costs (~$200/visit).

Project Benefits

Lower Costs

Affordability

Enabling widescale water submetering and quality monitoring can help reduce costs by detecting leaks or other issues with water delivery.

Equity

Equity

Most multi-family housing tenants overpay for water due to inaccurate submetering - this technology can increase metering accuracy, which can catch issues early and help reduce costs.
