The Download: climate tech goes public and the AI Hype Index returns

This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology.

Climate tech companies are going public. What’s next?

Solar and battery company Solv Energy went public in February, hitting a $6 billion valuation. X-energy, which builds small modular nuclear reactors, followed at $11.5 billion. Then came geothermal company Fervo Energy, reaching a market cap of about $12.4 billion.

All three have been IPO success stories. And it doesn’t feel like a coincidence that they’re racing to provide electricity in an era of rising demand, driven partly by data centers.

What does this boom reveal about the future of the grid? And what comes next? Read the full story to find out.
