Factor2 Energy, a German clean energy startup, has raised $9.1 million in its latest funding round to accelerate development of its next-generation fuel solutions. The round brought together a strong lineup of investors, including At One Ventures, High-Tech Gründerfonds (HTGF), Gründerfonds Ruhr, Verve Ventures, and Siemens Energy Ventures.

Founded by Felix Böhmer, Michael Wechsung, and Jörg Strohschein, Factor2 Energy is reimagining how industrial sectors transition away from fossil fuels. Their platform focuses on producing renewable, carbon-free fuels at scale, targeting industries like steel, chemicals, and transport  - sectors that account for some of the toughest emissions challenges.

Tackling the Hard-to-Abate Sectors

While much of the world has moved forward with renewable electricity generation, the reality is that sectors such as steelmaking, cement, aviation, and shipping remain some of the hardest to decarbonize. These industries require high heat or dense energy fuels that cannot be easily substituted with electricity or batteries alone.

Factor2 Energy is focused on creating solutions for precisely this gap. Its approach enables the production of synthetic fuels derived from renewable sources  - energy carriers that can integrate into existing infrastructure without requiring massive overhauls. This is particularly critical, because many industrial supply chains cannot pivot overnight.

By solving this, Factor2 Energy is positioning itself as a key enabler of industrial decarbonization, one of the fastest-growing needs in the global energy transition.

Strategic Funding Partners

The $9.1M round is backed by a diverse mix of deep-tech investors and corporate venture arms with serious expertise in climate and energy.

• At One Ventures has a portfolio focused on climate tech with a mission to back companies that can radically reduce emissions.
  
• High-Tech Gründerfonds (HTGF) is Germany’s most active seed investor, known for spotting early-stage technical breakthroughs.
  
• Siemens Energy Ventures, a corporate venture arm, brings not only capital but also industry partnerships and commercialization pathways.
  
• Regional funds like Gründerfonds Ruhr and pan-European players like Verve Ventures add both localized support and cross-border expansion opportunities.
  

This blend of strategic and financial investors provides Factor2 Energy with both capital and practical scaling advantages  - from supply chain partnerships to industrial pilot programs.

A Founder Insight: Why Scaling Energy Tech Requires Hybrid Capital

Here’s something many first-time founders underestimate when entering deep tech and energy markets: pure venture capital alone rarely gets you to commercialization.

Unlike software, where you can iterate cheaply, clean energy technologies need expensive pilot plants, long lead times for permitting, and capital-intensive scaling phases. Factor2 Energy’s mix of funding  - blending classic VC, regional innovation funds, and corporate venture  - is exactly the type of financing structure that aligns with the sector’s realities.

Corporate investors like Siemens Energy Ventures aren’t just writing checks; they’re future customers and collaborators. Regional funds provide ties to policymakers and industrial partners, critical for early demonstration projects. Classic VCs help maintain discipline on growth and market fit.

For founders building in similar heavy-capex industries, the lesson is clear: design your fundraising roadmap around hybrid capital stacks. Secure validation from corporates early, ensure regional support to ease deployment, and then use institutional VCs to unlock global scale. The sequencing of investors matters almost as much as the size of the round itself.

How Factor2 Energy Will Use the Funds

With $9.1M secured, Factor2 Energy is expected to:

• Scale pilot projects with industrial partners across Europe.
  
• Advance R&D on fuel conversion efficiencies and production economics.
  
• Expand its team of engineers and commercial specialists to accelerate customer acquisition.
  
• Position itself for regulatory opportunities, particularly in the EU where the Fit for 55 package and carbon pricing mechanisms are creating new demand for low-carbon fuels.
  

By focusing first on industrial customers with urgent decarbonization pressures, Factor2 Energy can prove both the technical viability and economic attractiveness of its solutions.

Market & Industry Outlook

Factor2 Energy’s funding comes at a pivotal moment for the global clean fuels market, which is forecast to expand rapidly over the next decade:

• According to the International Energy Agency (IEA), demand for low-carbon hydrogen and synthetic fuels could reach 500 million tonnes annually by 2050, representing a multi-trillion-dollar opportunity.
  
• The European Union is aggressively targeting industrial emissions, with its Carbon Border Adjustment Mechanism (CBAM) set to penalize carbon-intensive imports starting in 2026. This creates a competitive advantage for European manufacturers using cleaner fuels.
  
• In Germany alone, the government has committed more than €9 billion toward hydrogen strategy funding, aiming to become a global leader in green hydrogen technologies.
  
• Analysts project the global e-fuels market could surpass $140 billion by 2035, driven by aviation and shipping adoption.
  

Factor2 Energy sits at the intersection of these forces: industrial demand, regulatory push, and global capital flow into decarbonization. With the right scaling strategy, its solutions could play a central role in reducing emissions where electrification isn’t feasible.

Challenges Ahead

Despite strong momentum, challenges remain for Factor2 Energy and peers:

• Cost competitiveness: Renewable fuels still face higher costs compared to fossil fuels, though this gap is narrowing as renewable energy prices fall.
  
• Infrastructure scaling: Building production plants and distribution systems requires time, capital, and regulatory clarity.
  
• Global competition: Startups in the U.S. and Asia are also racing to commercialize similar solutions, creating a crowded competitive landscape.
  

Success will depend on not just technological execution but also securing long-term offtake agreements with industrial partners, something the team appears well-positioned to achieve given its investor lineup.

The Bigger Picture

The $9.1M round signals growing investor conviction that startups like Factor2 Energy can address some of the world’s most difficult decarbonization problems. By targeting sectors often overlooked in the early stages of the energy transition, the company is carving out a high-impact niche.

If Factor2 Energy executes successfully, it could not only capture a significant market share but also help rewrite the playbook for how startups fund, scale, and deliver in capital-intensive industries.
