Ranked by disclosed equity funding and recent momentum, the 1,484 Energy Storage Tech companies we track across the United States have pulled in $42.6 billion in total disclosed funding, with 10 unicorns already in the mix. Plug Power leads at $2.1 billion raised, followed by Base Power at $1.3 billion. Those are big numbers. But what do the actual revenues look like?
The validated filings tell a more grounded story. Across 17 filers, the combined revenue pool hits $2.9 billion, with a median of roughly $10 million per company growing at about 10% annually. Livent Corp. earned $883 million last year, 14 times the sector's median net income of $24 million. Bloom Energy Corp posted $746 million, up 134% year over year, and netted $74 million, 3 times that same median. I find that Bloom's growth rate is the figure worth sitting with. Plug Power filed $710 million at 11% growth. And as recent reporting on battery storage enabling renewables makes clear, lithium-ion integration and solar PV are the themes pulling capital right now, with app-layer energy tools showing median install growth of 28% year over year across 141 tracked apps. The money's real. So is the distance between the biggest earners and everyone else.
