Started "Lokalvarme ApS" (Local heating ApS) in the spring of 2026 to help energy communities to get up and running.

During the the winter of 2025-2026 i got really scared by the geopolitical development, and I therefore designed a common solar+battery system for the living community where I am living, that has the capability to deliver power to the community if the electricity grid where taken out. This sparked the idea for a startup.

The living community is housing 24 families and has a shared geothermal + solar heat system. I was part group to found the living community from the very beginning. (Started the project in 2013 and moved in, in 2016).

I have worked for DTU Wind & Energy Systems since 2007.

I hold a bachelor in Physics and Nanotechnology from DTU (2008), and a Master in Sustainable Energy from DTU (2011).
