The Challenge.

Startup 4 Climate is one of our most urgent initiatives to date. We believe that innovation and collaboration is key as we move into the future, which is why this challenge is aimed at young companies with ideas that can speed up the energy transition and limit global warming to 1,5 degrees.

The energy transition encompasses initiatives that promote the switch from current energy and transport systems to those systems and solutions that are smarter, more efficient and more climate friendly.

The shortlisted submissions pitch their ideas to our jury of experts from the fields of entrepreneurship, energy, green technology and climate action. The winning startups are granted a SEK 2 million prize to help catalyze their ideas and contribute to the energy transition.

Over 70 percent of all energy produced in the world today is lost as waste heat. Zigrid’s patented technology is part of a circular energy system where industrial, low-grade waste heat that was previously lost is now captured and converted into new energy. This energy can then be returned to the business or to the electricity grid.
