Sage Geosystems | Cindy Taff on CORE Knowledge Podcast

Episode 85

Wednesday, July 1, 2026 • Duration 39:05

The geothermal landscape has evolved quite a lot in the last 5 years since I began recording episodes here on this show, we have seen billions in capital raised, successful pilots, full scale commercial projects constructed and lately a record breaking IPO. Zooming in, 5 years ago I sat down with then fairly new startup Sage Geosystems to talk about their unique EGS tech, plans for the future and what they hoped to accomplish.

Fast forward to today, they have deployed their first grid connected commercial project, raised significant capital and put together a gigawatt pipeline they are actively working to bring to market.

Critical Energy | Spencer Jackson on CORE Knowledge Podcast

Episode 84

Wednesday, April 29, 2026 • Duration 49:09

Factory built, deployed in modules, cost effective, flexible power generation systems for geothermal? That's right, Critical Energy is aiming to change the landscape for geothermal development timelines with their cutting edge, factory built, modular ORC turbines. Spencer Jackson, Founder and CEO, spent many years at SpaceX working with systems while much hotter, not that different and he thought to himself why not tackle heat recovery in a meaningful way. With their approach, the landscape for geothermal could be radically revitalized, lowering barriers to entry, lengthy time to markets, decreasing costs, supply chain bottlenecks, etc. ultimately unlocking more resource and capital faster.

MB Century | Robert Mandjes and Greg Thompson on CORE Knowledge Podcast

Episode 72

Wednesday, August 28, 2024 • Duration 47:05

When designing and developing a project, it is important to consider the full generation life cycle in order to incorporate efficiencies, cost savings, safety measures, inclusivity, and so much more. In the case of geothermal, it allows for innovative thinking around how to incorporate a mindset of circular economy benefits and engaging with the local community to ensure mutual benefit. I had the pleasure of sitting down with Greg Thompson, the acting CEO at the time of the interview at MB Century and the Director of International BD, Robert Mandjes to discuss the rich history of MB Century and how they are innovating and continuing to lead in the design and development of various energy projects across New Zealand.

Hephae Energy - Pandora | Steve Krase on CORE Knowledge Podcast

Episode 68

Wednesday, April 24, 2024 • Duration 44:09

There will always be the doubters who say that something is impossible and will never be achieved or realized. To people like Steve and John of Hephae Energy, it is music to their ears, a challenge accepted to go beyond where anyone has before. That is what they are doing for the geothermal industry in developing rotary steerable and MWD tools that can operate precisely downhole at temperatures well above 175 degrees C.
