spankmeister posted:Yeah when crude reaches a high number like $200 a barrel (note: number pulled entirely out of rear end) then shale could be economically viable. But right now we still have more easily accessible sources of crude. Wikipedia says that with current technology sustained prices above 70-95 USD per barrel makes oil shale profitable. Though possible future tech could drive the break-even price down to $30 USD/barrel.

QuarkJets posted:That can't be right though, oil barrel prices have been in that range for years. Today it's $86/barrel. American oil companies would be going nuts with oil shale development if oil shale were that profitable at this price range You are right, I skimmed through the article too quickly and got my phrasing wrong. Shale breaks even not when market price is that much; rather a barrel of shale costs that much to produce so crude needs to cost that or more before shale can start becoming profitable.

Kiwi Ghost Chips posted:There's also the ocean extraction method. Does anyone know what the latest prices for that are? I vaguely remember the last time this came up in discussion that someone had pegged it at ~$300/unit for salt water extraction which was ~double-ish of what the market price was. I'm at work right now so can't Google too much but I saw a few articles talking about how Oak Ridge came up with some new method of extraction that would bring the current cost down so if I am even close to accurate you can use that as a rough baseline. Maybe on my break I'll find something or I'll just go back to lurking.

Has there been any publicly released data from animals collected outside the Chernobyl zone but near by it that tracks the amount of Cesium et al is present in their systems? I imagine for the most part unless you have a migratory species that regularly passes directly through the zone the spill over would not be too much. Or if the animals had particularly large ranges that had some percent overlap with the zone.

Electric Wrigglies posted:Ok, but if you had a wind grid and this is at night (so you didn't have the thermal problem from probably using old coal plants being operated in load following), currently using 75 GW of demand and 8% of capacity plus 20 % reserve means you need that is evidently needed plus count on 10% of windfarms offline for maintenance gives 75*1.25/8*100/90*100 = ~1,300 GW of installed windfarms. Assume new 8 MW units, you need around 162,000 of them. Assuming 30 year life that means a cheeky 5,400 k wind mills to be installed a year. ~5k if you assumed 100% availability. 4k if you assumed no reserve. I don't understand the point you're trying to make in relation to what happened. All energy inputs had a forecasted amount of power they were expecting to contribute to the grid yesterday. Wind was providing just about near the forecasted amount meaning it was operating as intended. The big shortfall in power from forecasted levels was the 12GW of coal and gas that failed to produce when it was expected to. I don't really see the point in discussing a hypothetical all wind Texas grid because one, it wouldn't ever happen and two, I think that'd be a stupid idea. Phanatic posted:It's almost like backstopping wind and solar with a power plant technology that hovers around 97% of nameplate capacity is a good idea. Basically this. e: also third point I forgot to mention, blaming wind is just the same dumb bullshit Abbott and co. already did last time during the winter storm when the gas infrastructure started freezing because they did gently caress all to prepare for another winter storm after they got hosed the last last time back in 2010 (2011?).

But I'm still confused on how what you're saying connects to the topic at hand, which is the failure of coal and gas power impacting the Texas grid. Meanwhile today is another day where the Texas power grid has an unexplained by Abbott gap in the power inputs from coal and gas while the other energy sources are matching their forecasted levels: https://twitter.com/douglewinenergy/status/1547217843871252480?s=20&t=e2_1nJ4qTDTFIVOhuPcG7Q

If we are going zero fossil fuel economy that would involve also replacing every joule of energy we currently use in every ICE everywhere, not just cars with electric motors. And we need to have completed this conversion about 20 years ago, so basically as fast as we can possibly do it. For people who say we don't need nuclear power, how are we going to account for that additional demand on energy generation when we are already seeing that a no fossil/no nuclear hydro/wind/solar with some kind of energy storage plan is struggling to provide full grid power today at today's requirements without gas and coal backstopping it?

silence_kit posted:If you meant “on demand” instead of “demand on” here, nuclear is pretty uneconomical for that task. When you run a nuclear power plant at full capacity, it generates very expensive electricity because the power plant was built at great cost. When you hold the nuclear power plant in reserve, and run it only when needed to fill the gaps (at partial capacity), you’re making what was already very expensive electricity even more expensive. No I mean we have to replace the entirety of the gasoline for internal combustion engine infrastructure over to our grid if we want to go zero carbon. Which means our energy generation grid will need to produce even more power on top of what it would need to do just to keep up with "normal" growth. Currently we have nowhere in the world that has hydro/solar/wind only grids that can operate without the backstopping of carbon generation in the form of coal or gas. My question is, how do you propose we deal with this extra demand on our energy grid from converting every internal combustion engine over to electric motors without nuclear in the mix?

Isn't it still the case that we don't have pre-approved reactor designs and every new plant must be treated as if coming to us fully formed in a vacuum rather than taking this already known and regulation approved reactor design and putting it into this other kind of geography than the last one? If we wanted to stamp out a bunch of plants then settling on one or two or three reactor designs with some bolt in solutions for cooling and storage and stuff that can be interchanged based on constraints of the geography of the plant location could really speed things up. If the industry is already exceptionally highly regulated than with sufficient motivation those regulations could be reworked to streamline the build and run process without really making any sacrifices to safety.

Discendo Vox posted:There are standardized plant designs, which are certified for 15 years and then undergo cyclic review and renewal. Obviously I haven't spent a huge amount of time on the site but just clicking through a few things its good that the reactor design and site process are independent of each other. This is where I am probably going to get the most divergent from reality in want vs possible but I feel like it'd be more streamlined if the government provided the pre-approved designs and even possible sites to put them rather than waiting for private industry to apply. Though if we're going full pie in the sky best possible reaction to climate change re: generation we should nationalize the whole drat thing and build out like its a war effort for survival (because it is).
