Form Energy Lands $750M for Grid Battery Technology

In a significant endorsement of long-duration energy storage, Form Energy has successfully closed a massive $750 million Series G funding round. The capital infusion, spearheaded by T. Rowe Price, with substantial participation from a consortium of prominent investors including Breakthrough Energy, Coatue, Sequoia Capital, Franklin Templeton, Janus Henderson, PEAK6, Prelude, Engine, TPG Rise, Energy Impact Partners, NGP, GE Vernova, Blindspot, and the M&G Catalyst Fund, will fuel the scaling of its innovative iron-air battery technology. This development arrives as the global energy sector grapples with integrating intermittent renewable sources and the increasing demand for grid stability.

The substantial investment underscores a clear market trend: venture capital is prioritizing foundational technologies with tangible real-world applications over speculative consumer plays. Form Energy's iron-air batteries are designed to provide multi-day energy storage, a critical capability for grid operators seeking to balance supply and demand as solar and wind power penetration grows. Unlike conventional lithium-ion solutions, which typically offer shorter discharge durations, Form Energy's approach leverages abundant and low-cost materials like iron and air, positioning it as a potentially transformative solution for grid resilience and decarbonization efforts.

This funding round propels Form Energy's total equity raised to over $2 billion, signaling strong investor confidence in its technological viability and market potential. The company aims to deploy its batteries at utility scale, addressing the growing need for reliable power reserves that can sustain the grid through extended periods of low renewable generation or peak demand. The involvement of major financial institutions and strategic corporate investors, including Xcel Energy and GE Vernova, highlights the industry's recognition of the imperative for advanced energy storage solutions.

The broader venture capital environment, while robust with global funding reaching record levels in the first half of 2026, is exhibiting a marked selectivity. Data indicates that a significant majority of investment is flowing into artificial intelligence and deep technology sectors. However, the substantial capital directed towards Form Energy, alongside other significant rounds for companies like Swedish AI coding platform Lovable ($400M) and Indian EV mobility provider Yulu ($93M), demonstrates a continued appetite for "hard tech" and infrastructure plays that tackle fundamental economic and environmental challenges. This focus on sectors with clear revenue models and demonstrable impact is a hallmark of current investment strategies.

Beyond energy storage, the day's deal flow also highlighted continued investor interest in enterprise-focused AI and specialized software. Startups such as CodeRabbit, Blacksmith, and Skan AI, which offer solutions for code quality, AI development, and data infrastructure respectively, alongside cybersecurity firm Mindgard, secured considerable funding. Furthermore, the biotech and drug discovery arenas also saw notable capital injections, with companies like Boulevard Bio and Remepy attracting investment. This diverse set of deals reinforces the narrative of VCs backing domain-specific innovation and scalable infrastructure critical for industrial advancement.

The strategic alignment of these investments with national and global priorities, such as the energy transition and the advancement of domestic technology champions, is also evident. Form Energy's expansion aligns with global mandates for decarbonization, while rounds for companies like Lovable reflect efforts to bolster European tech ecosystems. The participation of automotive industry players like BMW i Ventures in funding AI platforms such as CodeRabbit further illustrates how venture capital is actively supporting sectors deemed vital for future economic competitiveness and technological sovereignty.
