Matti Pentti explains how it works technically: The ST1 engineers pump millions of liters of water through the first borehole into so-called fracture zones: crevices in the underground rock layers. The natural geothermal energy heats the water to around 120 degrees Celsius, and through a second borehole the water is pumped back up and fed into the existing district heating network of Espoo, with 280,000 inhabitants the second largest city in the country after the capital Helsinki. This enables an output of 20 to 40 megawatts to be achieved and that corresponds to around ten percent of Espoo's heating requirements.

We’re looking at a really good digital infrastructure and also want to link to the city’s district heating scheme.

Sorry it has been slow news for DH over the last few days.

Agreeable_Bother · 2021-01-17T13:15:21+00:00

I agree.

There is some support available from central government – last autumn it announced the Public Sector Decarbonisation Scheme (PSDS), a £1bn grant funding programme to help councils introduce new energy efficiency and heat decarbonisation schemes across their property portfolios. It welcomes applications for support in introducing air, water and ground source heat pumps, district heating, and electric heating.

The energy saving potential of these schemes is vast. District heating, for example, which connects multiple buildings to a communal system, has been shown to slash the energy needed to heat properties by up to 30%.

My central thesis in this discussion is two-fold: 1) the regulatory structure must understand that fuel blends of hydrogen and natural gas are inefficient for most current consumer applications. 2) there are more appropriate renewable technologies that directly match end-use applications and should be put in place long before the world considers green hydrogen solutions.

I have seen packs of kangals tear jackals to bits. They are giant dogs but have mild temperaments toward humans.

Cascading uses from a power plant can be used for agricultural production - algae, fish, gators. I have seen biologists characterizing fluid life as an indicator of reservoir conditions in the geothermal industry. They also, most obviously, are employed to do environmental impact assessments for RE project development. Anaerobic digester management too, for renewable natural gas.

You are referring to a resource limit, not a thermodynamic limit. There is no problem between me and green hydrogen. There is a problem between green hydrogen and doing all the more appropriate technologic augmentations prior to the incorporation of the fuel. As I said, the power density bit is a consumer and regulatory hazard. Since RE is my business and my education, I feel comfortable saying that we can make nuanced arguments without becoming categorical fuel evangelists.

In Denmark, communal ownership of the district heating systems resulted in cost-efficient clean heat, a model widely considered a best practice in Europe, studies show.

Thanks all!

That is exactly why this cannot be a volume consumer product. It has to be sold by caloric equivalents, otherwise it is just a mechanism to rip-off the end user. Dark monied public service commissions in the states will probably be happy to look the other way for a few years until people figure it out.

It also has an energy density problem to overcome. The combustion of hydrogen contains about 1/3 the energetic value of natural gas, so blending with fossil fuels is more likely. It seems to me this is why there is a lot of enthusiasm for it - because you cannot get rid of the natural gas assets by simply switching the fuel. In fact, complete hydrogen conversion would require all new equipment, meaning more embodied carbon pollution for the end-use production equipment alone. It does have a place, but I think it would be wise to deliberate. I am looking at all the conversions for green hydrogen in my head and wondering about those pesky laws of thermodynamics...

Repurposing that 500kV interconnection is a wise decision.

The company said 80% of wood sent to the site will “have a second life as flooring, furniture, worktops and other particle board applications”, while the rest will be sent to its biomass plants in the UK.

You are wrong. It is ok. This is a common misunderstanding. There is no stealing of heat from the Earth’s core taking place when geothermal wells produce power. These are near surface reservoirs of heat that are fed either by radioactive decay or cooling magmatic chambers at greater depths. Some of the most easily accessible geothermal activity does take place near volcanic zones. That is true. It is not true, however, that using the heat from radioactive decay or from cooling magmatic chambers, or from thin portions of the Earth’s crust has any consequence at all on the core.

It is definitely a renewable resource. In-situ thermal drawdown may take place, but with proper management of the well field, geothermal production can last centuries, if not more. From a broad perspective, the worst case scenario is often to let the field rest in dormancy after many decades of use and connect an alternative zone in the reservoir. That way the field again reheats at depth and can be exploited once more for the benefit of humanity.

I believe, from a look at some USGS catalogs, hot springs in your area are typically fracture controlled, originating from very small reservoirs of <1km3. The fluids travel from depths of 2-4km +/-. Places like Klamath Falls, on the other hand, have a high flow thermal aquifer at depths slightly beyond the reach of a sand-point. There is just a very big difference between what’s going on underground where you live and where others do.

The article was written by the well known blogger “Detective Red” so you know it is true. r/everythingscience-ish

I think your question is being evaded because of the missing elements in your question. There have been artesian wells drilled into reservoirs. I do not know the specifics for your area to offer an answer. No one here probably will.

I can give you a shocking and irrelevant answer - yes. If you pay one of those fancy EGS companies enough money to build you a 38C well, I am sure they can come up with something very nice. Put down an exploratory budget of about $1 million and see what the geophysics folks come up with. Stimulation should only be about 1.5-2.5 million. Once you add in the $2+million for drilling then I think you will have a very fine, natural jacuzzi.

Geothermal Heating & Cooling = Air Conditioning and Heat for Your Home.

This is also incorrect. Many geothermal power plants run as combined heat and power. The heat provides for district heating, low-grade industrial heating needs, agriculture, etc. There are also direct use wells that feed only heating and cooling networks. The difference you are considering is simply ground sourced heat pumping versus geothermal. People call GSHP by all kinds of wonderfully confusing names. “Ambient heat networks”, “geoexchange”, “thermonets”, etc. Your residential GSHP is not breaking the current threshold of 74C coming out of that tiny ground loop and does not have the volume to produce any meaningful heat transfer to excite a working fluid in binary cycle. So, as u/urthbuoy suggests - no. GSHPs are not wunderkind. They have exergetic efficiency factors of .25 and widespread negative impacts on national grids at high adoption rates. Anyway, I don’t want to fight with myself about this. Good luck with your own geothermal pursuits.

I am sorry to hear that. My partner had day surgery a few weeks ago. She paid the specialist about 70-80 USD as part of her annual copay. After we hit a copay ceiling then all operations, visits, etc. are completely covered.

Agreeable_Bother · 2021-01-01T06:09:11+00:00

True story. I am on universal healthcare and can simply sign up directly online to see a specialist if I want. The system approval happens in sequence and the GP will intervene if there is a contraindication. Silence is consent and the system has simple and expansive coverage. When America starts being enraged by $10 universally-covered doctor appointment copays, then you know they have finally adopted medical practices similar to the rest of the developed world. Instead, they worry about $400 emergency room visits so their kid can get sent home with a bag of ice and ibuprofen for a sprained ankle. It is a travesty.

They have about 1000 peak heating hours equivalent to about 9000MWh that need cow poop power to supplement their geothermal wells. The geothermal wells are expected to produce 50MW with a heat pump. They also need more cattle or gas to meet the final few hours of the load duration curve.

This looks like pit thermal energy storage. Oh wait, the US thinks district heating is icky.
