Energy Storage Funding Dips as Deal Activity Surges Worldwide

Companies working on energy storage raised $8.9 billion in the first half of 2026.

That was slightly less money than they raised during the same period in 2025.

However, there were many more deals this year.

Venture capital funding also went down, reaching $1.6 billion.

Debt and public-market financing made up most of the money raised.

CATL received the largest financing in that group, at $5 billion.

Companies also bought or merged with other businesses much more often.

Project acquisitions more than doubled and covered about 14 gigawatts of capacity.

The report does not explain why total funding declined.
