The curtailed power from wind turbines just goes to ground and is "wasted", kind of like flaring or venting natural gas. If one puts a plant to produce hydrogen next to big wind farms, an agreement could be reached with the wind power operator to procure "curtailed wind power" at very low cost, perhaps 0.5 cents per kWhr, maybe less. Currently for wind power producers any "curtailed" wind power gets zero. If the hydrogen plant was run by the wind power operator the cost would be zero. What do you think all the power lines would cost to set up your hydrogen plant and maintain it? Have any such plants ever been built? Quote Share this post Link to post Share on other sites

Consider that fossil fuel is likely to be limited and we will need to find substitutes in any case, It is likely, based on the global carbon cycle that about 20% of carbon emissions will remain in the atmosphere for 10,000 years or more, the rest gets reabsorbed by the biosphere, there are a number of feedbacks that may gradually make the problem worse such as melting permafrost as the Earth warms which leads to more carbon emissions a it occurs. The more this is studied by climate scientists, the more they are convinced that the problem is real and actually worse than at first believed. Also keep in mind it will take time to transition to alternatives to fossil fuel, and many of those alternatives (including simply better built buildings meeting Passivhaus standards and other energy efficiency measures) are likely to be cheaper than fossil fuel as peak output is reached for oil in 2025, coal in 2030, and natural gas in 2035. I have no problem with the overall data showing the CO2 intermediated temperature rise. The problem is the broad spread of the projections and the really terrible history of predictions. Once you calibrate a model, it should be able to predict results in the Temp vs. CO2 into the future. Those predictions have not come in the ballpark of what actually happened. The range of uncertainty in model predictions is huge. We have every reason to worry about both extremes, being in the bottom range, meaning that little happens, or at the top, where significant changes happen. We should be able to see the contribution of particulate cloud cover due to the China Quarantine shutting down 1/2 of its economy, and the jet emissions' water aerosol cover now reduced by 1/4 due to less Chinese air travel. It would be interesting to compare to the days following 9/11 where we had a 1 C temperature rise above normal seasonal temp. We don't know how much particulate cover loss due to renewables and NG reduction in dirty fuels will cost us in temperature rises. The big benefit is a rise in evaporation from the oceans, that could relieve the arid conditions of the subtropics in the last half century. Unfortunately, it would also flood Europe every winter. And it has the potential to RAISE temperatures further as coal and heavy oil are squashed. Some models attribute more that 1.2 C of temperature suppression to particulates, one quote I came across is 2.5 C. Fortunately on this count, Germany is intending to fill in its baseload with Lignite when, as happens 17% of the time, they have no significant renewables output. Looking at individual data points you can clearly see the particulate cover effect falling off and doing so very rapidly after 1980. I like to joke that the EPA caused global warming. You see much less of the rising temperature trend in pristine locations that remain outside major metro hot spots and were never under the local particulate clouds. No doubt that we should be preparing for the reduction of viable FF energy sources over time. So where that is economical, we should definitely remove the red tape from standing in the way. Even subsidize the capital investment if countries can afford to. Taxing FF just creates anti productive income for governments and increases the costs of transition to renewables. But my main issue with the CO2 reduction efforts is that it is going to happen anyway. The demographics of the developed economies are forcing a rapid reduction in demand on top of the economic and policy driven reduction. The boomers going into savings mode and retiring is reducing per capital consumption of FF in the developed world. The much reduced younger generations require no marginal investment in infrastructure. Second, the economics of solar in particular offer a 20% drop in FF consumption in the near future with existing storage technology. The main limits are Lithium processing due to limits on Iridium supply. And for US based thin film, it is Tellurium supply that remains an issue if demand rises again. Third is the restricted supply of Neodymium from China, which does not publish credible resource and reserves numbers.

D Coyne + 305 DC March 3, 2020 3 hours ago, KeyboardWarrior said: Resultant efficiency of EVs is lower than an ICE. Start with powerplant efficiency, then account for all losses through transmission, loss through charging, loss through discharge, electric motor efficiency, and so on. Don't tell me that we justify it through making use of excess power, because if everybody switched to an EV then so called surplus power would be wholly insufficient to power the mass of EVs. No not really correct, first EVs will not replace ICEV instantaneuosly. The energy needed at plug or tank is what I am talking about. Generally ICEV get about 25% of the energy contained in the fuel in the tank converted to work at the axle. For an EV the energy at the plug is converted to work at the axle at about 90% efficiency. If you want to talk about electricity production and power line losses, then we have to include the entire fossil fuel production, refining, and distribution process as well. If we did that, ICEVs would look far worse, so we have to do apples to apples. Easiest comparison is at the tank or plug in my view. Note the comined cycle natural gas power plants have about 60% efficiency, grid losses are about 10% and other losses converting AC to DC to charge battery about 5%. For typical oil production today energy out is about 5% of energy in at most, most studies show about a 30 to 1 ratio. 1 Quote Share this post Link to post Share on other sites

LNG in the US will also fail as there is an oversupply of Natural Gas Worldwide and at current price levels LNG is also a money losing proposition. When output slows down and natural gas prices rise to a level where natural gas can be produced profitably, then many of the natural gas fired power plants will become stranded assets as they will not compete well with wind and solar as prices continue to fall over time. You would have to talk the Mr Smith and Walras about how this works. The issue is that in most locations you don't have anything remotely competitive with sub $3 NG. LNG remains profitable beyond the collection pipeline. Upstream from there it is essentially priced as a waste product for the near and intermediate future. As Coffeeguyzz pointed out, the breakenven cost keeps dropping. We are yet to hit the point where new wells are using lower quality reserves. There are also new in hole pumps to aid in recovery of NGLs. Well productivity is still rising. I believe what you are saying will happen in time, just that that time scale is far longer than you are saying. The oversupply conditions in LNG are a capital constraint on LNG trains, particularly to unload at the destination markets. But we have only started the transition to LNG marine fuel and now large megatrucks in mining and construction. Now that LNG pods have been standardized it will catch on rapidly. That is 16% of oil demand falling off the cliff. I totally buy into your free H2 scenario and free electrogas. It is a solution to the problem of peak production surpassing demand and practical storage for long chunks of time, as renewables market share becomes sustantial.. 1 Quote Share this post Link to post Share on other sites

I am saying that the general climate change community relies on the heavily contaminated databases. Fraudulent data coming from practically ALL country's doctoring of their temperature records keeps popping up in the scientific news. The entire field has thus been put in question as a science altogether.

So you’re not going to count the energy it took to extract fuel for the power plant? You’re going to lose if you put both systems in their entirety side by side. I knew you would mention combined cycle too. Why don’t we, then, take advantage of our thermochem technology and just produce gasoline from natural gas? That’s more efficient than combined cycle with EV, and you don’t suffer from pitiful energy density and charge time. 1 Quote Share this post Link to post Share on other sites

We sure spend a lot of money, especially helping our adult kids. The top quintile don't reduce spending that much till they actually approach retirement, but their savings rate does climb dramatically in the post 50 age group either by them or by their pension plans. It starts with a 25% drop in spending transitioning from covering children's college, last car, downsized house, etc.. Their travel is a one or two month or so winter event. It does not last very long into their retirement. Typically only 5 years till the joy is sucked out of travel by health limitations. Low returns from bonds plays a heavy hand in it near and at retirement. They shut off rooms in winter and don't heat them. The typical EU retiree over 70 now spends 60-70% less than they did in real terms when they were 40-50 age group. You can see it in the fall of European oil consumption for these 20 years before EVs and PHEVs had any effect.

Most electricity is sold on fixed priced contract, but there is still enough activity to make an active spot market which wind farms have been known to crash by giving away their power. Then the next hour when the wind dies, the conventional plants have wound down as they can't sell anything, the price spikes. Wind and solar badly distort both the short term markets with wild variations in supply, and then distort the long-term because the conventional plants have trouble using the short term markets.

Good to know. It would appear that the addition of storage batteries could be beneficial and allow "time shifting". But would the addtional cost be economical? I sent a recommendation to our premier that an "Engineering Infrastructure Study" be conducted (using the correct disciplines and planners) to create a plan to transition smoothly from all carbon to the best we could "economically" achieve and afford. No set deadlines from politicos. Someone else said about 20% RE was estimated. Our premier is considering SMR's.

See http://static.berkeleyearth.org/papers/UHI-GIGS-1-104.pdf Chart below attemps a CSALT model based on simple linear regression on Berkeley Earth's Gloabl land ocean temperature cs the five variables of the CSALT model (which is admittedly far simpler than Global Land Ocean Carbon Cycle models). The centered 15 year average is plated for Global Land Ocean Temperature vs the "Model" which has an adjusted R-squared of 0.8563. Far from perfect but the physical reality is far more complex than what can be captured by such a simple conceptual model. The transient climate response of the model (which ignores long term feedbacks as the ocean slowly warms with a typical 400 year lag) is about 2 C for this model for a doubling of atmospheric CO2 concentration. The model was done in 2016 so annual data was only available though 2015 at the time, I have not updated the model of late. 1 1 Quote Share this post Link to post Share on other sites
