Understanding the “Missing Middle” in Climate Finance
Startups in the climate technology space often excel at securing early-stage funding. Venture capitalists are willing to invest in proof-of-concept solutions, enabling innovators to test and validate their ideas. However, as these companies move beyond pilots, they encounter a critical bottleneck: scaling. Moving to industrial deployment requires significantly larger pools of capital—often more than early-stage investors can provide.
Simultaneously, these firms are not yet large or de-risked enough for traditional infrastructure financing or private equity. This creates a funding gap widely referred to as the “missing middle.” It is particularly acute in sectors like energy, heavy industry, transport, and building infrastructure—industries that are both capital-intensive and vital for achieving meaningful emissions reductions.
The Decarbonization Acceleration Fund aims to address this gap by providing growth-stage equity capital. This approach allows promising climate technologies to scale production, expand commercial operations, and deploy solutions across complex industrial systems. By supporting companies at this crucial stage, DAF ensures that innovation does not stall, paving the way for systemic climate impact.
Target Sectors: Aligning Environmental Impact with Economics
DAF strategically focuses on sectors that contribute the largest share of global emissions while offering high-impact opportunities for decarbonization. These sectors include:
- Energy: Supporting clean energy generation, storage solutions, and smart grid technologies that enhance efficiency and reliability.
- Industrial Processes: Transforming heavy industries such as steel, cement, and chemicals, which have historically been difficult to decarbonize.
- Transport Systems: Improving logistics efficiency, electrifying vehicle fleets, and deploying sustainable shipping technologies.
- Buildings: Driving energy efficiency through low-carbon construction materials, advanced HVAC systems, and smart building automation.
By focusing on these sectors, Climate Investment ensures that environmental goals are closely intertwined with operational and financial performance. Scaling decarbonization solutions requires more than just technology—it demands collaboration, expertise, and a clear pathway to measurable economic outcomes.
Early Investments Signal Industrial Focus
Since its launch, DAF has already made four notable investments, each reflecting the fund’s dual focus on environmental impact and industrial integration:
- JessCo Solutions – Develops emissions control equipment for industrial facilities, helping factories meet environmental standards while optimizing performance.
- XNRGY – Specializes in high-efficiency cooling systems for data centers, reducing energy consumption and operating costs.
- XOCEAN – Provides ocean data and subsea survey capabilities using autonomous surface vessels, improving marine monitoring and logistics.
- Zeitview – Offers AI-powered visual inspection and analytics for infrastructure, enhancing operational efficiency while lowering emissions.
Each investment illustrates DAF’s approach: decarbonization solutions must integrate directly into existing infrastructure while delivering measurable operational and financial benefits.
Operational Value Add (OVA): Making the Business Case for Climate Technology
A defining feature of Climate Investment’s strategy is its Operational Value Add (OVA) framework. OVA evaluates the economic benefits created when new technologies improve baseline operations—whether by reducing capital expenditure, lowering operating costs, or increasing revenue.
This focus on financial performance is critical for driving adoption in industrial sectors where cost competitiveness remains a decisive factor. Since 2019, Climate Investment estimates its portfolio has delivered more than $600 million in operational value through the OVA framework.
Patrick Yip, Managing Director and Head of Growth Equity, explained:
“Growth equity succeeds when scaling is repeatable. By pairing capital with hands-on industrial collaboration and an OVA lens grounded in actual cash flows, we help companies prove value, de-risk implementation, accelerate adoption, and expand across global infrastructure markets.”
This operationally grounded approach ensures that decarbonization technologies are not only environmentally impactful but also commercially sustainable—a key driver of long-term industrial adoption.

Leadership Perspectives: Driving Industrial-Scale Change
Joshua Haacker, Chief Investment Officer at Climate Investment, emphasized the fund’s mission:
“DAF was created to close the gap between proven decarbonization technologies and large-scale deployment. Many solutions already exist that can reduce emissions in heavy industry while improving operational performance and profitability. What’s often missing is the capital beyond venture and the commercial pathways to bring them to major industrial players and governments. DAF is designed to provide both.”
Haacker and Yip’s insights highlight a fundamental principle: climate technology investment is not just about funding innovation—it’s about enabling solutions to operate at scale and deliver measurable impact.
Strategic Backing From Industrial Leaders
DAF has attracted strong support from both founding investors and industrial partners, including:
- Saudi Aramco
- Occidental
- Baker Hughes
- CMA CGM
- Development Bank of Japan
- PTT Group’s ExpresSo NB
- Taranis Investment
This alignment demonstrates a broader trend in climate finance: industrial incumbents are increasingly central to scaling solutions rather than remaining on the sidelines. Their involvement provides portfolio companies with direct access to large customers, industrial expertise, and deployment pathways—ensuring that capital investment translates into real-world impact.
The Missing Middle in Context
Over the past decade, early-stage climate finance has grown significantly. Venture capital, philanthropic support, and government incentives have expanded the pool of funding available to startups, enabling innovators to develop and test new solutions. Yet as technologies move beyond pilots, scaling remains a persistent challenge. Many promising solutions struggle to secure the larger amounts of capital required to deploy at industrial scale, leaving them stuck in the so-called “missing middle.”
Bridging this gap is critical for achieving meaningful climate action. Industrial systems and infrastructure networks are inherently complex, and integrating new technologies requires more than financial resources—it demands operational expertise, strategic partnerships, and practical deployment pathways. Growth equity funds like DAF are emerging as a solution, combining substantial capital with hands-on operational guidance to accelerate adoption, reduce risk, and demonstrate measurable economic and environmental value.
Linking Emissions Reduction to Economics
A defining feature of Climate Investment’s approach is linking environmental impact directly to economic value. In sectors like heavy industry and transport, companies are far more likely to adopt technologies that provide both emissions reductions and clear operational benefits. By emphasizing cost savings, efficiency gains, and revenue opportunities, DAF ensures that portfolio companies can scale sustainably and gain traction across global industrial markets.
This dual focus—climate impact and business value—makes the fund a model for future climate finance initiatives seeking to accelerate adoption without compromising profitability.
