Bridging the Climate Valley of Death: CEV Taps Ramsamy for European Expansion

LONDON, UK – October 27, 2026 – For the past decade, the venture capital ecosystem has excelled at funding the spark of innovation. Seed rounds and Series A checks have flowed freely into climate technology startups, backing brilliant engineers and physicists with novel ideas for decarbonizing our world. Yet, as these startups mature, they inevitably encounter the "valley of death"—that perilous chasm between a successful laboratory pilot and a first-of-a-kind commercial facility. Bridging this gap requires more than just capital; it demands specialized project finance expertise, operational rigor, and a stomach for industrial-scale risk.

Today, Clean Energy Ventures (CEV), a prominent venture capital firm targeting multi-gigaton carbon reductions, signaled a definitive strategic shift to conquer this very chasm. The firm announced the appointment of Aruna Ramsamy as Managing Partner, tasked with leading its European operations from a newly established London office. The hire is not merely a geographic expansion; it is a calculated evolution from early-stage venture capital into the complex, capital-intensive realm of growth-stage equity.

"Aruna's experience spanning venture capital, growth equity, and project finance will be a tremendous asset to CEV as we deepen our support for companies entering their next phase of growth," said Daniel Goldman, Managing Partner at Clean Energy Ventures. "Having helped navigate the financing of large-scale, first-of-a-kind industrial projects, she understands what it takes for companies to transform from technological innovations to commercial enterprises."

The Transatlantic Climate Push

The strategic timing of CEV's expansion into Europe is no coincidence. While the United States has the Inflation Reduction Act driving domestic clean energy deployment, Europe has aggressively countered with the Net-Zero Industry Act and stringent decarbonization mandates. These policies have created a massive, legally binding market for industrial decarbonization technologies.

Historically, CEV has operated comfortably in the early stages of the venture lifecycle. Managing over $400 million across two funds—including a recently closed $305 million second flagship fund—the firm has typically written initial checks ranging from $500,000 to $8 million. By reserving up to 40 percent of its capital for follow-on investments, CEV has supported its founders through the early turbulence of company building. However, the sheer scale of the European industrial transition requires a different magnitude of financial firepower.

American funds are increasingly planting stakes in London and mainland Europe to capitalize on this regulatory momentum. Industry insiders note that the European market offers a unique combination of aggressive corporate net-zero targets and a pressing need for energy security, accelerated by recent geopolitical shifts. By establishing a senior presence in London, CEV is positioning itself to not only export its North American portfolio companies into the European market but also to aggressively source homegrown European deep-tech innovations.

Bridging Europe's Series B Funding Gap

Ramsamy's appointment directly addresses a structural flaw in the European venture landscape: the notorious Series B funding gap. Recent market data paints a stark picture of this mid-stage capital drought. Between 2020 and 2024, the average Series B round in Europe hovered around $35.2 million, roughly 20 percent lower than the $45.5 million average seen in the United States.

More alarmingly, only 15 percent of European climate tech startups successfully graduate from Seed to Series B, compared to a 25 percent graduation rate stateside. This attrition has resulted in a staggering $13.5 billion funding shortfall over the last four years. The European venture ecosystem is teeming with micro-funds and early-stage incubators, but it severely lacks mid-sized vehicles capable of deploying the $25 million to $100 million checks required to build commercial-scale climate infrastructure.

Furthermore, traditional European institutional investors, such as pension funds and insurers, have been largely sidelined from venture capital due to stringent regulatory frameworks like Solvency II. While the European Investment Fund (EIF) has recently launched a €200 million Cleantech Co-Investment Facility to help plug this "second equity gap," public money alone cannot bridge the divide.

"The European climate tech ecosystem has successfully incubated world-class science, but founders frequently hit a brick wall when seeking the $50 million needed to build their first commercial plant," noted one London-based climate fund manager. "The arrival of growth-oriented US funds with dedicated European partners is beginning to change that calculus."

CEV's expansion places it in direct competition—and potential collaboration—with established European growth funds like World Fund and 2150. However, CEV's deep technical bench, comprising a team where over 60 percent are trained physicists and engineers, offers a distinct advantage in evaluating complex hardware and industrial processes.

Financing First-of-a-Kind Industrial Decarbonization

To understand the significance of Ramsamy's appointment, one must look at her track record in financing first-of-a-kind (FOAK) industrial projects. FOAK facilities are notoriously difficult to fund. They are too mature for traditional venture capital, which balks at the high capital expenditures and single-asset risk, yet too risky for traditional project finance lenders, who demand proven operational track records and guaranteed off-take agreements.

Ramsamy brings a playbook forged in the crucible of these exact challenges. Prior to joining CEV, she served as Managing Director at Just Climate, a $1.5 billion fund established by Generation Investment Management. There, she navigated the complexities of scaling asset-heavy companies in hard-to-abate sectors.

The stakes of FOAK financing are perfectly illustrated by the trajectory of European green steel startup Stegra (formerly H2 Green Steel), a company where Ramsamy has held board experience. Despite securing a monumental €1.4 billion financing package, Stegra has faced the harsh realities of industrial scaling, encountering higher-than-anticipated project costs and construction delays. These hurdles underscore the immense execution risks inherent in replacing legacy industrial infrastructure.

Conversely, Ramsamy's experience extends to successful FOAK de-risking models. During her tenure in senior leadership at Climate Investment (formerly OGCI), a fund exceeding $1 billion, she was involved with Svante, a leading carbon capture provider. Svante recently secured up to $100 million from the Canada Growth Fund specifically designed to accelerate and de-risk its commercial carbon capture projects. This type of strategic, catalytic capital is exactly what CEV aims to deploy and orchestrate in its growth-stage evolution.

"For the last decade, CEV has built a differentiated portfolio of deep-tech companies tackling some of the toughest challenges in the energy transition," said Aruna Ramsamy, Managing Partner at Clean Energy Ventures. "Now, it's time to build on CEV's strong foundation to accelerate the commercialization of its portfolio and develop investment platforms that can provide the capital these companies need to scale. Europe's decarbonization priorities are increasingly aligned with industrial competitiveness, energy security, and economic growth, creating a powerful market for the technologies CEV backs. I look forward to positioning the firm to capitalize on new opportunities across Europe and North America."

A New Playbook for the Energy Transition

The broader climate tech investment landscape is currently undergoing a flight to quality. In the first half of 2026, private climate tech financing reached an impressive $41.3 billion. Notably, while seed and Series A funding experienced a cooling period, growth-stage investment surged by 78 percent. Institutional capital is consolidating behind clear winners—companies with proven science, robust leadership teams, and realistic paths to commercialization.

CEV's overarching investment thesis mandates that any prospective portfolio company must possess the potential to mitigate at least 2.5 gigatons of CO2 equivalent by 2050. Achieving scale of that magnitude cannot be done in a laboratory; it requires pouring concrete, securing massive industrial supply chains, and navigating complex regulatory environments across multiple continents.

By bringing Aruna Ramsamy aboard to anchor its London operations, Clean Energy Ventures is not just expanding its geographic footprint. It is acknowledging that the next decade of the energy transition will be defined not by who can invent the best technology, but by who can successfully finance and build it at a commercial scale. As the climate crisis accelerates, the ability to bridge the valley of death has evolved from a niche financial skill into a global economic imperative.
