On today’s episode, we’re speaking with Martin Schichtel, the CEO and Founder of Kraftblock, a thermal energy storage solution for industrial clients that use high heat. 

Today, they’re delivering their 5th project. All of which have been paid for by their customers — yep, you read that right. They have not used equity to pay for these pilot and demonstration projects. 

Their tech takes excess heat or electricity and turns it into heat, stores it in these engineered rocks. When demand is needed, they deliver the power. Reliable and affordable energy storage is the key to the energy transition. 

Get the full episode today to hear….

**How they managed to get their customers to pay for their pilots and demonstration projects
**The role consumer demand for cleanly produced products is having on the world
**The importance of validating the idea WITH CUSTOMERS before you build your pilot
