PV-Storage-Hydrogen at Google’s Silicon Valley Campus
How Google is revolutionizing campus energy with integrated solar, battery, and hydrogen technologies.
The Imperative for Site Energy Transformation
In the heart of Silicon Valley, Google’s data centers are setting a benchmark with an integrated PV-Storage-Hydrogen model, solving two critical challenges: escalating power demand and zero-carbon mandates.
- 18% of regional electricity consumed by data centers
- $0.22/kWh California industrial electricity cost
- Carbon-neutral by 2030 target
“Google’s transition from grid dependency to self-reliant energy systems signifies a paradigm shift in clean energy architecture.” — HighJoule CEO
