Climate Tech Startups

Climate tech startups are young companies building products and services to cut greenhouse gas emissions, remove carbon from the atmosphere, or help industries and communities adapt to a warming world. Their work spans energy storage, next-generation batteries, carbon capture and utilization, low-carbon fuels, industrial decarbonization, grid software, and efficiency tools for buildings and data centers.

Why it matters now

The sector is moving through a period of sharp contrasts. Public funding that once anchored many early-stage projects has become less predictable. Shifts in federal grant programs and efficiency regulations are forcing founders to rethink financing and timelines. Yet deployment of some technologies, grid-scale battery storage in particular, keeps growing on market demand rather than policy alone.

The rapid expansion of AI and data centers adds another dimension. It is raising electricity demand, sparking debates over who pays for grid upgrades, and drawing large tech companies into partnerships and incubators focused on cleaner power. Meanwhile, technologies like carbon capture face hard questions about cost and real-world performance as pilots move toward commercial scale.

What you'll find here

This hub tracks the companies, capital, and policy decisions shaping climate innovation worldwide, including:

• Funding and policy: venture rounds, grant awards and cancellations, and regulatory changes
• Energy storage and batteries: deployment trends and advances such as solid-state chemistries
• Carbon management: capture, removal, and conversion of CO2 into fuels and materials
• Data centers and the grid: how rising power demand intersects with clean energy goals
• Global pilots: early-stage projects in emerging markets and beyond

Coverage focuses on what's working, what's stalling, and what it all means for the path from lab to market.
