What International Cleantech Network does
International Cleantech Network (ICN) is a privately held, non-profit global alliance of 22 leading cleantech clusters headquartered in Copenhagen, Denmark. Founded in 2009, the organization functions as a network facilitation entity rather than a software product company, connecting cities, corporates, and innovators across four continents in thematic areas including energy, circular economy, and watertech. Its core assets are relational: 130+ city and regional government engagements, 250+ university relationships, and access to 7,000+ startups and SMEs via its member clusters.
ICN's primary offerings are project initiatives and consortium coordination rather than discrete products. Notable programs include the HI2 Valley hydrogen project in Austria (€20 million in Horizon Europe funding, ~€600 million in total investment, ~50 partners) and the Every1 EU energy knowledge platform, whose full course library was opened publicly in May 2026. It maintains long-standing strategic collaborations with C40 Cities, ICLEI, the Solar Impulse Foundation, and NYSERDA, and holds official observer status at COP30.
The business model is non-commercial in the traditional sense; ICN is funded through a mix of EU and international project grants, member cluster contributions, and consortium partnership overhead, with no disclosed pricing tiers or direct revenue from selling products. Customer segments are Cities & Regions (e.g., Rio de Janeiro, Cape Town, Vancouver, Copenhagen, New York State), Corporates (e.g., Novafos, Metro Vancouver), and EU Project Consortiums. The organization operates with 1-10 employees and no disclosed management team.
