TL;DR: Regional Cleantech in Central and Southeast Europe Thrives in 2026
Cleantech ecosystems in Central and Southeast Europe (CEE/SEE) have moved from the sidelines to the forefront of global innovation. By 2026, they boast affordable infrastructure, specialized talent, and EU-backed funding opportunities, enabling startups to challenge outdated models and scale faster than mature-market competitors.
• Emerging hubs in Romania, Poland, Bulgaria, and Slovenia support geothermal energy, battery storage, and circular economy platforms.
• Founders face persistent funding barriers, with criteria often favoring larger or more established players.
• EU's staged funding model now enhances early-stage opportunities, offering scalability for regional innovators.
Aspiring entrepreneurs can capitalize on local resources, academic collaboration, and EU programs like the Horizon 2020 initiative to fast-track growth.

In recent years, cleantech has transitioned from an “emerging” sector to an indispensable pillar of global innovation. By 2026, this is no longer a conversation about potential. It’s about execution, scale, and urgency. Regional cleantech ecosystems, particularly in Central and Southeast Europe (CEE/SEE), have stopped waiting on the margins of global discussions. Today, they are at the forefront of creativity, pushing the boundaries of technology and policy while challenging outdated funding models. As someone deeply embedded in entrepreneurship and innovation ecosystems, I , Violetta Bonenkamp , have seen firsthand how cleantech leaders in underrepresented regions are rewriting the rules of participation in this industry.
What Makes Regional Cleantech Critical in 2026?
Historically, cleantech innovations from Central and Southeast Europe faced what many now call the “geography penalty”: limited access to capital, slower adoption of nascent funding instruments, and an overreliance on domestic investors who often lacked sector-specific expertise. But 2026 looks different. Regional players have proved that their models can not only adapt but thrive. Regions like Romania, Poland, Slovenia, and Bulgaria are showing that innovation does not have to reside solely in well-funded hubs like Berlin or Amsterdam.
Why Are They Scaling Now?
- Skills and Workforce Growth: Local hubs are fast-tracking the development of specialized talent in areas like geothermal energy, circular economy platforms, and battery storage solutions.
- Affordable Infrastructure: With lower costs for land and operations compared to Western Europe, startups can experiment with higher margins for error.
- New EU Funding Models: Initiatives by the European Innovation Council (EIC) now include stepping-stone funding to reduce barriers for early-stage innovators in these regions.
- Rising Enterprise Value: Companies are growing faster than comparable firms in mature markets, making them attractive for both private equity and international venture capital.
The change isn’t random. It reflects years of advocacy and the relentless work of founders who refused to play by the rules of geographic exclusion.
What Are the Funding Barriers Regional Founders Still Face?
European ecosystems have made strides, but cleantech founders in CEE/SEE still talk about the struggle for “bankability” , a term meaning readiness to meet funding requirements that were often designed with larger, older companies in mind. Here’s where we’re currently stuck:
- Overly Mature Criteria: Funders often look for market-ready solutions, ignoring earlier-stage startups working on validating their technology.
- Supply Chain Misfits: Although local materials are abundant, aligning them with European green goals is a logistical headache.
- Access to Domestic VC: Many investors in the region support SaaS or Web3 startups but lack expertise in the deeptech needs of cleantech companies.
The Future: Flexible, Inclusive Funding Instruments
The recent updates to the EIC funding model reflect this understanding. For instance, the two-stage funding approach provides €300,000 for initial technical tests at Technology Readiness Level (TRL) 4 and up to €2.5 million for scaling initiatives. This staged model allows smaller startups to grow without unrealistic expectations early in their lifecycle.
Lessons and Opportunities from Regional Leaders
As the founder of Fe/male Switch, which actively incorporates cleantech startups into its incubator, I’ve had the privilege of working alongside trailblazers like Suzana Carp from Clean European Futures and Matija Gatalo from Slovenia’s ReCatalyst. These leaders combine incredible technical expertise with something even rarer: an ability to rally fragmented ecosystems into something resembling a unified voice. That’s no small feat in Europe’s patchwork quilt of bureaucracies.
- Suzana Carp: Used her network to launch initiatives like Cleantech for SEE, a program designed to bridge the “geography penalty” in Southeastern Europe.
- ReCatalyst: A Slovenian power storage startup proving that local ingenuity can rival global competitors, especially with Google-backed partnerships.
- Clean Energy Hubs: Emerging geothermal hotspots in Romania and Poland are drawing data center operators, creating strong new revenue streams.
Practical Steps for Aspiring Cleantech Founders
Are you an entrepreneur wondering how to break into cleantech , especially when based in a region that’s not Silicon Valley or Berlin? Start with these practical tips:
- Use no-code platforms to model early solutions faster than hiring a dev team.
- Partner with academic institutions that can provide access to laboratory-grade testing facilities at subsidized rates.
- Focus on EU funding windows like the Horizon 2020 program and EIC advanced innovation calls.
- Collaborate with larger corporations (e.g., through licensing agreements) to jumpstart scale opportunities.
- Join ecosystem advocacy groups , their lobbying keeps smaller startups visible at forums where decisions are made.
What’s Next in Cleantech?
The cleantech playbook is being rewritten as we speak. It’s moving toward decentralization, advanced AI for material science, and more localized energy solutions. China remains a key player, but hyperlocalized regions like CEE/SEE provide the agility and creativity that broad industrial policies miss. For founders tired of sitting in the shadow of established hubs, now is the moment to act.
The urgency of climate challenges combined with newly equitable funding access points makes 2026 a pivotal year for cleantech innovation everywhere , but particularly in regions that have been “done waiting.” Let’s be clear: the competition has already started. Are you ready to join it?
