>> Indeed (this is a work in progress, and may indeed not be possible), however the industry already uses huge amounts of H (therefore short-term storage for intermittency compensation is possible), and more and more vehicles do so (therefore a quite large distribution network for intermittent consumers is possible). > Incorrect. We have plenty of experience working with hydrogen produced by steam reformation. But that emits CO2 Not pertinent: I was writing about green hydrogen (no CO2 emissions), as stated above: "green-hydrogen-fueled gas turbines". > cannot be used for energy storage Many factories do have hydrogen tanks, the unknown territory is storing huge amounts of it in the long term (ongoing experiments try to use salt caves), both goals not necessary for the electrical system. > Energy storage is a problem that has resisted an effective solution for a long time There was no incentive, as fossil fuels are incredibly convenient. >> France > So investing in nuclear yielded great reductions in CO2 emissions Not-so great, if you consider that electricity is only at max a quarter of consumed (final) energy, and also the total amount of emissions (taking into account importations): abstaining from emitting is easy if other nations are producing goods for you. https://ourworldindata.org/grapher/share-co2-embedded-in-trade?tab=chart&region=Europe&country=FRA~DEU https://ourworldindata.org/grapher/share-co2-embedded-in-tra... > and brought fossil fuel use to near zero. In France 9% of electricity is produced by burning fossil fuel. In France fossil fuels remain the main source of energy: https://ourworldindata.org/grapher/fossil-fuels-share-energy?tab=chart&country=~FRA https://ourworldindata.org/grapher/fossil-fuels-share-energy... >> Germany >> really launched its transition in 2011 > So Germany invested in renewables and even after more than 30 years of investment Sorry but 2011 to now is 11 years, not 30 > it hasn't seen nearly as big a reduction in CO2 emissions. Starting from a way higher amount of consumed energy, in a way more difficult context (crisis...), without de-industrializing as much as France... in 2010 Germany's emission intensity were 471 (before shuting down many nuclear reactors) and in 2020 314. This is a pretty good result! France also reduced its emissions, but only thanks to renewable sources (no new nuclear reactor since 1999, because an attempt to build a new one, ongoing since 2007, fails) https://www.eea.europa.eu/data-and-maps/daviz/co2-emission-intensity-10 https://www.eea.europa.eu/data-and-maps/daviz/co2-emission-i...
