Beyond Debunked

The seldom told success story of the renewable electricity generation in Europe. Wind & solar are a perfect seasonal match!  Isin't that handsome, like the number 10 on the Barcelona afternoon training ground pitch back in the days. Wind & solar electricity generation monthly variation 2022. Wind electricity generation monthly variation in the EU 2019-2022. Solar electricity generation monthly variation in the EU 2019-2022.

Let’s work with the gravity. Australian National University study identifies more than 600 000 sites and 23 000 TWh worth of locations for pumped hydro electricity storage. Turns out that 1% of that would be enough for three days (72h) worth of global electricity. Worldwide electricity production was 28466 TWh 2021. Annually the 1% could provide 9100 TWh of electricity assuming a modest storage capacity-to-production ratio of 39. In that ratio I mean how many times the whole reservoir is totally utlized during the year. Potential pumped hydro storage (PHS) sites in Spain and Portugal. This highlights the pumped hydro storage as a viable option for the NZE energy system. Pumped hydro should get more attention. It is 1. conventional, 2. long-term, 3. highly efficient, and 4. cost-effective compared to many other energy storage methods. Latest developments includes an opening of Tâmega gigabattery in Portugal which deploys 1160 MW power and 40 GWh of storage capacity. That is 20% of the ...

 I agree that IEA's stated policies scenario is already outdated after 2022 PV data, but that is not what IEA predicts. IEA has three different scenarios in the 2022 World Energy Outlook (WEO) out of which we seem to follow the NZE prediction= Green (Linear model 2022-2040). IEA different scenarios and their relation to Carbon Brief solar chart . There's a long history to this but these scenarios need clarification. Stated policies, SP= "reflects current policy settings" (which seems to be the same as WEO 2022 used in Carbon Brief chart.) Announced pledges, AP= "highlights the 'ambition gap' that needs to be closed to achieve the NZE" Net Zero Emissions, NZE= What is needed to achieve NZE. There is no such thing as WEO 2022 scenario. IEA models are made to show the difference between current policies and what needs to happen. Here's more about the IEA definitions:  https://www.iea.org/reports/global-energy-and-climate-model/understanding-gec-mode...

 Did you notice that the swan song of internal combustion engine (ICE) happened already in 2021? Me neither. ICE new car emissions have increased 17% since 2017 ICE+ PHEV new car emissions have increased 8% in the EU. Only EVs have kept up the slight decrease of average new car emissions. We don't have the 2022 data yet. New car emission 2017-2021 in the European Union. Vehicle registration and emission data is ACEA's, and the EU electrification fleet development from the EAFO statistics. Worth to note that plug-in hybrid emissions are officially only 38g/km which is 2-3 times less than the real-world estimates ( Krajinska, 2022 ). European commission is updating the PHEV emission utility factors, but only with a marginal solution, and only by 2025-2027! If you calculate the effect of this PHEV discrepancy, the new vehicle emission development without EVs looks even more bleaker. Average emissions in the EU 2010-2021. This, I'm afraid, means that the EU passenger car emissi...

Short correction to the @BloombergNEF lithium mining estimate, and to my I yesterday's tweet. Instead of 712 kt of (Li), it seems that the actual mining forecast is around 240-260 Kt of Li tons.  >>> Enough for around 30 million EVs. BloombergNEF lithium mining and refining forecast from the article . That being said, the key take away from yesterday's tweet is also incorrect. Lithium mining will not meet the 4,1 TWh battery manufacturing demand forecast (by BNEF), which now also seems inflated. My earlier post based on BNEF forecast. BNEF 07/2022 Li mining forecast seems to be quite far off from other estimates. I was mistaken by the @paola_rojas tweet where Li  tons were used, but BNEF estimate is likely in LCE tons. If the BNEF Li mining forecast is in LCE tons, there would be no growth from 2022-2025:  690 kt >>> 712 kt, which is untrue according to others. Australian government predicts a domestic production growth from 335 (2022) to 470 kt LCE by...

USGS mineral commodity summary 2023 is out. Here’s a short take from to critical mineral output & reserve growth. TLDR: Mine production is growing but the reserve growth is far exceeding the demand. We are not running out of minerals. Best performer: Lithium 🏆 Li reserves are up by 4,0 Mt from last year, which would be plenty for the the whole decade worth of demand if needed. EV barometer: Annual reserve growth would be enough for more than 500 million EVs. Current identified resources are 98 Mt. Other minerals: Cobalt reserves are up 0,7 Mt which is a solid growth from last year. EV barometer: Annual reserve growth would be enough for more than 125 million EVs (NMC 811). Co mine production rose from 165 kt to 190 kt. Copper reserves are up 10 Mt which was also similar growth to last year. Copper obviously has many application, but from EVs perspective the annual reserve growth would be enough for more than 430 million EVs. Graphite reserves are up 10 Mt and Nicke...

As a google-born 90s kid I haven’t spend much of my time in mines but I’m quite accustomed to data mining. I hope that you haven’t spent much of your time worrying about @JohnLeePettim13 thread.  Earth will not be destroyed because of energy transition related mining.  That being said, I respect the ones who have done the “heavy-lifting” as we need more some of the industrial minerals, but seems that the years spent in mines doesn't correlate with the knowledge of the mineral requirements, availability or the scale. Lee Pettimore's twitter thread . For the context the thread has got more than 5 million views and 20k retweets. It has been shared by many prolific influencers such as  @DecoupleMedia and @vtchakarova who commented: "Decarbonization means the great acceleration of dirty mining." Lee Pettimore's thread has got too much attention even though almost all the claims and scales are false. In addition to this mineral outcry, @DecoupleMedia has also given ...
