iiinova — where your digital self keeps evolving

Maybe we do end up doing very well on unlocking huge demand flexibility, but historically we've really struggled at this. I've always been an advocate for not putting all our eggs in one technology (or regulatory) basket. We need to push on all of these options, and there's no reason we can't.

000

There's a huge amount of value we can get out of better utilizing our system, and in a high-VRE future it'll probably make a lot of sense to pay people not to consume (or let them voluntarily curtail). But we're never going to get large chunks of industry to just turn off for days to weeks.

100

It's not impossible, but I'm pretty comfortable saying that demand response is never going to obviate the need for clean firm options. It'll help of course, maybe reduce the scope of that need, but just like clean firm isn't a "silver bullet," neither is DR.

So the question becomes: what does "modeling the grid properly" look like? Because I'm not aware of any studies that show no role for clean firm if we care about getting close to a zero-carbon grid. Like I say in this article, the optimal system almost certainly features a diverse resource mix.

Looks like transferability of tax credits is maintained. Foreign Entity of Concern language is substantively different from House bill, but still applied throughout. Critical question: is this workable for industry to comply with? Safe harbor language clarified (good). Stay tuned...

What does the future of enhanced geothermal power generation look like? Fervo offered an update to partners and investors at its #capeconnect event today, showcasing progress on its 100MW Cape Station project in UT. I tagged along and I learned a lot. Some highlights based on my notes follow… 🔌💡

The advanced geothermal company Fervo says it drilled a 15,700 foot well and reached temperatures of 500°F (260°C) in just 16 days of drilling. That’s a big improvement from last year, when it drilled an 8000 ft well and reached 370°F temps in 41 days. www.linkedin.com/posts/timlat...

In particular, elimination of clean electricity tax credits would remove a key driver of early EGS adoption and reduce the long-run benefits of successful scaleup. It is critical that these supports remain in place if emerging technologies like EGS are to achieve their full potential.

040

Long-term outcomes are sensitive to near-term deployment. Our findings suggest that efforts to facilitate early deployment and better understand uncertainties in enhanced geothermal’s cost and learning potential should be key near-term policy and development priorities.

101

Such a large role depends on substantial reductions in the cost of EGS wellfields, which we argue must be driven largely by advances in reservoir design.

100

...EGS could plausibly grow to contribute up to a fifth of total US electricity generation by 2050 and drastically reduce the cost electricity generation and decarbonization even east of the Mississippi – a much larger role for the technology than has been previously assumed.

101

We find that if a) EGS performance continues to improve incrementally in the near-term, b) supportive federal policies remain in place, and c) EGS costs fall with scale at a rate similar to unconventional oil and gas...

This means that we can explore the conditions under which EGS (or its competitors) could achieve ‘commercial liftoff’ through a virtuous cycle of increasing deployment and falling costs, and the long-run implications for the US electricity sector if it is able to do so.

100

This analysis uses an ‘experience curves’ framework to model the evolution of costs for EGS and other emerging technologies over time, assuming that – like wind, solar, batteries, and unconventional oil and gas before them – the cost of these technologies will fall with increasing deployment.

It first leverages data from recent pilot projects to develop the first empirically-grounded near-term cost projections for EGS power in the US, then uses these as inputs to an electricity system capacity expansion model to explore potential adoption pathways for EGS over the coming decades.

100

This paper builds on prior work to address two key questions: where and under what conditions could EGS deliver cost-competitive power in the near term, and to what extent could it contribute to electricity generation nationwide if it can be successfully brought to scale?

PJM gets a lot more (still deserved) attention on the subject, but Bonneville Power Authority has been absolutely abysmal at connecting clean power in Oregon and Washington. Just ONE project has gotten approved in the last decade, and advertised wait time is 15 years!

Everyone says enhanced geothermal is the next fracking. That's only a little "bit" true. The shale fracking boom was a product of its unique market structure. Enhanced geothermal is very different. Latest from me and @buddyyakov.bsky.social at CPE—here's what a geothermal boom *really* requires:

For emerging techs like EGS this is mostly fine for the time being (Fervo says they can build up to 4 GW at their first project site in Utah), but to really hit massive scale and unlock the long term potential of the technology you need CA's market and resource base

California has some of the best geothermal resources in the world and very supportive demand-side policy and market conditions, but my personal experience has been that developers are generally staying away from the state due to permitting challenges and risk
