Stanford Energy Seminar | Enhanced Geothermal Systems: Are We There Yet?

[@chrisconklin2981]

What I see coming is a national electrical distribution grid. The USA is about two thousand miles wide with four hours of time zones. One or more east/west DCHV power line would load balance across the nation. Morning solar in the east afternoon solar in the west. Geothermal all of the time. Wind and other sources as available. Behind the meter and system batteries would provide load balancing. One for all and all for one.

With regard to running counter to solar timing -- could you soak daytime power into injecting hot water to store the thermal energy?

[@ivantijerinaf1207]

got any on Advanced systems?, as in enhanced vs advanced ...geothermal systems.. : )

[@kevinleecaster2698]

Good lecture as usual Dr. Horne. I can't recall what city, but one recently allowed their public gas utility to switch to a district heating business model. Interested to see how that turns out.

Thank you, we can prevent these phenomena like cyclone by using this hot seasonal atmospheric condition and geothermal in summer happen in surface of coastline, there are many countries in coastline with seasonal hot weather and water condition by using this energy not only is economy but also reduce global warming like Japan, China, Mediterranean countries, Iran, Mexico, Us, Canada, (Africa and Arabian countries....) that I mentioned in my profile.

Do the temperature contours follow uplifted/intrusions of granite as implied by the "Geologic structure" slide? If so, are there advantages to drilling at the base of steep gradients of granite such as in the Eastern Sierras & Central Oregon?

Oil and gas fracked wells traditionally use sand and the like to hold open fractures against pressure, w relatively low flow, a 1-2 kg per sec. How are a fractures held open w 60-80kg/sec working to remove sand?

[@Nill757]

The MIT feasibility target was 80kg/s, and 7000N deep, yes? Blue Mountain was 300M deep per this demonstration, yes?

[@rolandhorne8923]

Blue Mountain is about 3000 m deep.

[@Nill757]

How much water loss?

[@Nill757]

Pumping power? PE alone, m*g*h of 80kg/sec, depth 7km is 6MW, w say 60% eff pump, 10MW. Can that ever pay? Once again, much nearer surface, hotter rock seems to be required, ie rare geothermal conditions using traditional, not enhanced methods.

Think of thermosiphon effect

[@Nill757]

@@mohammadaljubran2456 I’m aware; I don’t think it significantly applies. You know better? The injection wells and recovery wells and generation system with steam expansion in between would have to somehow be a single phase system w little compressibility over 10km. I don’t see it. I do know some earlier egt pilot projects a few years ago were net loss power.

just use the fucking sun

just relax

[@nunobartolo2908]

@ applying heat extraction at scale can influence the soil in hard to predict ways from earthquakes to sink holes to ground aquifers it’s just not worth it solar is dirt cheap and so is energy storage now

@@nunobartolo2908 well, dirt cheap, an what is worth is the big issue here... not tecnology..
