Meanwhile, gridtech funding hit a record $316 million in Q1 2025, as aging power grids struggle to meet surging demand from AI data centers and electric vehicles Climate Tech Investment Trends H1 2025 | Sightline Report^[7]. Battery storage has also seen a threefold increase in investment since 2021, with projects like Canada's Hagersville Battery Energy Park demonstrating the viability of decentralized energy storage Infrastructure Quarterly: Q1 2025 | CBRE Investment …^[8].

Strategic Investment Opportunities

The shift toward resilience is not limited to traditional infrastructure. Mega-deals in nuclear energy, critical minerals, and sustainable aviation fuels (SAFs) are gaining traction, as investors prioritize technologies that secure domestic supply chains and reduce reliance on volatile global markets RELEASE: WRI Study Finds Climate Adaptation Investments Yield …^[9]. For instance, the U.S. Inflation Reduction Act (IRA) has catalyzed $369 billion in private climate investments as of 2025, with a focus on grid modernization and carbon capture Investing in the infrastructure of modern society^[10].

Private capital is also flowing into resilience-focused funds.
