[H2] Innovation Experience

Enhancing California's Energy Resilience and Reliability

2 *Clean hydrogen is defined as hydrogen produced with a carbon intensity equal to or less than two kilograms of carbon dioxide equivalent produced at the site of production per kilogram of hydrogen produced, and that does not use any fossil fuel in its production process.

A Key Solution:

Clean Hydrogen Microgrid

Clean hydrogen* microgrids can enhance community energy resilience by leveraging distributed renewable energy production, storage, and use.

Local energy generation reduces strain & supports the electric grid.

Supplies critical and emergency energy with zero greenhouse gas emissions during power outages.

[H2] FUEL CELL: Where hydrogen reacts with oxygen to create renewable electricity, with the only by-products being water vapor and heat.

[H2] BLENDING SYSTEM: Blending up to 20% clean hydrogen with natural gas for use in the [H2] home’s gas appliances.

6

[H2] STORAGE SYSTEM: Where clean hydrogen made by the electrolyzer, is stored —for days, weeks, or even months.

It keeps the systems running at optimal performance.

[H2] ELECTROLYZER: Uses solar energy to separate purified water into hydrogen (H2) and oxygen (O2).

The oxygen is safely released into the air, and the clean hydrogen (H2) goes into the [H2] Storage System.
