Munich’s Telura exits stealth with €4M to make deep geothermal economically viable

Telura has come out of stealth with €4 million and a bold claim: it can make deep geothermal economically viable almost anywhere on Earth.

The problem with geothermal energy has never been the heat. The Earth’s core sits at roughly 5,000 degrees Celsius, and the thermal gradient beneath the surface is consistent enough that, in principle, clean baseload power is available almost everywhere on the planet.

The problem has always been the drilling. The deeper you go, the harder and hotter the rock, and the faster conventional drill bits wear out. Economics turn unfavourable long before you reach the temperatures that would make a project worthwhile.

Telura, a Munich-based deep-tech startup founded in 2025, is betting it has a way around that constraint. The company has emerged from stealth with a €4 million pre-seed round and a technology it calls electro-impulse drilling: instead of grinding ...
