Clean hosted the ICN Annual Meeting in Copenhagen last week. Twenty cleantech clusters, four continents, three days. The conclusion was not new, but it has never felt more urgent.
There is a reason cleantech solutions do not scale as fast as they should. It is rarely the technology. The gap is almost always between the city that has a problem, the company that has a solution, and the funding mechanism that could connect them. Someone needs to sit in that gap permanently, with the trust of all three, and the ability to move between them.
That is what clusters do. And it is precisely why clusters are among the most effective drivers of the green transition we have.
Clean hosted this year’s ICN Annual Meeting at Copenhagen Business School, with our team in the room not just as organisers, but as active contributors to the conversations. What the three days confirmed is that the cluster model is not a nice-to-have. It is the operating infrastructure for climate innovation.
Ariesta Ningrum from the UN Climate Technology Centre and Network made the case plainly: structured global collaboration, not ad hoc relationships, is what accelerates the deployment of climate solutions across regions. The logic maps directly onto how Clean works at home. Public institutions define the need, funding creates the conditions, innovators deliver, and clusters are what keeps those three in the same room long enough to produce results.
The international opportunity is real
The same model that works in Denmark works everywhere. The needs are different, the funding landscapes vary, the markets are less familiar. But the role of the cluster is identical: bridge the gap, build the pipeline, get the solution deployed.
For Danish SMEs, this matters. Clean’s participation in the ICN network is not about visibility. It is about creating concrete entry points into markets where Danish cleantech is genuinely in demand. Sustainable tourism and coastal infrastructure in Brazil. Industrial decarbonisation across Europe. Climate adaptation in high-growth markets in Africa and South America. The relationships built at this year’s Annual Meeting feed directly into those pipelines.
The opportunity is there. Clean’s job, and the point of the ICN, is to make sure Danish companies can actually reach it.
