Project Update

The project was initiated late in 2020. Preliminary work is focused on gathering site energy load profiles, onsite wind power generation profiles, utility tariff data, and energy costs. The data gathered will establish project baselines and inform system design.

The Issue

Achieving California's energy goals will require a diversified portfolio of energy storage technologies. At this time the energy storage market is dominated by lithium-ion energy storage technologies, and the current market does not address the need for diversification. Additionally, there is a need to address energy system resiliency as it is anticipated that California will continue to experience long duration outages associated with wildfires. Technology demonstrations are needed to validate the multi-sector benefits that hydrogen energy technologies could provide.

Project Innovation

This project will field test a containerized hydrogen energy storage system integrated with renewable wind generation and a microgrid at a water district customer site. The project will validate the hydrogen system's ability to provide customer energy cost savings by improving the use of renewable generation and providing resiliency to the water district during Public Safety Power Shutoff events. The data obtained on capital cost, operating cost, performance and lessons learned will support commercial deployment.

Project Benefits

The project will validate the hydrogen system's ability to: provide customer energy cost savings and price stability; resiliency during Public Safety Power Shutoff events, load follow; provide baseload renewables; and, provide long duration storage of large amounts of power. The data obtained on capital cost, operating cost, performance and lessons learned will support commercial deployment. This project will provide benefits for the Water District, utility grid, and IOU ratepayers.

Affordability

The hydrogen energy storage system is expected to provide longer duration energy storage, which will enable greater use of on-site wind generation to reduce customer energy costs.

Energy Security

The hydrogen energy storage system, integrated with renewable generation and a microgrid, will store large amounts of power providing long duration energy resiliency for the customer site.
