The Issue

Roadways are locations of tremendous energy consumption and transformation, but also hold potential to generate energy. One approach for making existing roadways more energy sustainable is through regenerative energy devices such as piezoelectric devices that have the ability to harvest energy from deflection, vibrations, and applied mechanical stresses from overpassing vehicles.

Project Innovation

The project develops, designs, and installs a multitude of pavement-embedded devices to demonstrate energy harvesting from overpassing motor vehicles on the road in smart pavement covering 36 feet x 6 feet. The system consists of materials that exhibit the piezoelectric effect, generating an electric charge.

Project Benefits

The project demonstrates and assesses the potential of regenerative pavement technology, a roadway-embedded energy harvester that uses the untapped energy of car movements. The hardware devices developed using smart materials harvest energy from pavement deflections and vibrations under normal driving conditions. Energy performance data is collected to determine the technology's potential for widescale adoption in roadways and other surfaces.

Economic Development

Economic Development

Expected to displace a fraction of grid electricity with rate reductions of about 80% from the central grid. Retrofitting 1% of useable roadways (10% of total CA roads) could be about $260 per household in annual energy savings.

Environmental & Public Health

Environmental Sustainability

By retrofitting 1% of useable roadways (10% of total CA roads) with piezoelectrics, the environmental benefits include the reduction of about 1.2 kilotons of CO2 emissions and 16.8 million gallons of fresh water savings per year.
