While Google has announced its plans to test batteries for backup, the key draw of hydrogen is its cost-effectiveness at longer durations. When comparing levelized costs for a completely resilient, 100% renewable data center with zero emissions, hydrogen is $119/MWh, while batteries could be over $4,000/MWh to ensure 48 hours of backup power. This finding comes from Jack Brouwer, a professor of mechanical and aerospace engineering at the University of California, Irvine. Read More
