My research has consistently illustrated the value of 'clean firm power' -- available any time of the year, as long as needed -- as critical complement to 'fuel saving' variable renewables & energy-limited 'fast burst' batteries or demand flexibility. eg: sciencedirect.com/science/articl

Furthermore, we find that FLEXIBLE firm resources are more valuable than those that operate constantly as always-on "baseload" generation. When prices are zero much of the time, producing flat out all the time isn't as valuable as shifting your output to the most vaulable times.

's EavorLoop technology is one (of several) promising options for clean firm and flexible power. EavorLoop is a fully-contained, closed-loop system of deep wells that 'mine' heat from deep hot rocks like a massive subsurface radiator.

Additionally, EavorLoop has 'built-in' energy storage capability: by slowing down the circulation of working fluid in the closed-loop system, they can build up heat and store it for later, then speed up flow rate to produce more power at the most valuable times. Firm AND flexible

In my consulting 'side hustle,' DeSolve LLC, and I worked with 's to model the potential and value of flexible EavorLoops in a future Western US grid. The work was shared at Geothermal Rising Last week. Check it out here:

Like most early-stage technology ventures, has to prove themselves to the world, tackling big technical challenges in their first commercial projects. Those are coming soon, and I'm excited to see what their engineers can do!

In the meantime, as a member of the Advisory Board (eavor.com/our-people/ including fellow #EnergyTwitter personality ) to advise Eavor on energy systems, markets, and policy as they advance their clean, firm, flexible power technology to market.

Ack! Important clarification! @Eavor needs to cut cost per kilowatt of electric generation capacity from deep closed-loop geothermal by 90+%, NOT the cost of drilling specifically. Several ways to get that overall cost down, INCLUDING reducing drilling costs a lot.
