Joint projects with partner organizations

The Climate Movers Database is a public database that provides a transparent overview of European research in innovative climate technologies. The database was developed together with the Technical University of Denmark (DTU) and the IRIS Group from Copenhagen and aims to help interested people from research, politics and industry to identify suitable researchers and find possible synergies or build partnerships.

The Tech for Net Zero Alliance provides operational support for the joint project and offers the publicly accessible database on their website.

The Energy Resilience Leadership Group (ERLG) is a multi-stakeholder initiative led by Breakthrough Energy and Siemens Energy that brings together corporate CEOs, political leaders, financial institutions, and startups at the technology frontier. The Group was launched at the 2023 Munich Security Conference with the goal to enhance Europe’s energy resilience by rapidly bringing emerging climate technologies to scale.

The Tech for Net Zero Alliance provides operational support to ERLG and brings the perspective of innovative climate startups to potential partnerships.
