> I am a fan of nuclear energy for various reasons, and it's obvious that the safety and waste problems can be solved No you don't from your arguments. > The technology is not there yet. There are a lot of promising companies that are trying to solve the safety problem.[...], we don't have decades, we need to start replacing coal right now. That's bullshit. Even nuclear reactors designs from the 70s are statistically safer than coal. And kill a lot less than coal. > * nuclear energy is way to expensive. France had one of the cheapest electricity in Europe for 3 decades. Cheaper than anything produced by renewable right now. Nuclear is cheap but at the condition of government loans at very low interest rate and for multiple decades. That's has been analysed and reported many times already. > Power to gas for example has an efficiency of roughly 50%. There is today not a single installation world wide existing of power to gas to the scale it would be needed. And that would anhiliate any hypothetical cost of the renewable energy anyway.

And kill a lot less than coal. That's a strawman's argument, I'm not arguing for coal, I'm arguing for storage of renewables. > France had one of the cheapest electricity in Europe for 3 decades [...] Nuclear is cheap [...] That is simply false. The levelized cost of nuclear is about twice as high as that of solar or wind, see page 8 of the referenced EIA report [1]. > There is today not a single installation world wide existing of power to gas to the scale it would be needed Again, strawman's argument. The discussion is about what should be built, not what has been built. There are already megawatt scale plants running for years without problems [2], and there are shipping container scale demonstrators for higher efficient versions [3]. So it's pretty obvious that the technology around power to gas is well understood, and ready for mass production and deployment. > And that would anhiliate any hypothetical cost of the renewable energy anyway Again, this is false. As explained above, nuclear energy is twice as expensive as renewables, and power to gas has an end to end loss of roughly 50%. So in reality, renewables + power to gas has roughly the same cost as nuclear, without the proliferation, safety, security, and waste problems. And as an added bonus every MWh you use while renewables are producing costs half of nuclear ;).

  > One can be a fan of something without trying to blindly apply it to areas where it doesn't make sense. Starting a discussion with a "I'm a huge fan" before spending the next 10 min to debunk the thing is not "being a fan of" but just a sign of being hypocritical, or manuipulative or both. > That's a strawman's argument, I'm not arguing for coal, I'm arguing for storage of renewables. Renewable alone (Without Coal or Gas) implies nationally to have close to 100% of the production capacity in storage alone (Battery, power2Gas or hydro storage) to compensate solar / wind intermittency. Which no country on Earth is able to do right now: not even close to, not even as a minor part of their production. That is the real straw-man argument. Climate emergency need actions and solutions now, Nuclear is one of them. Dreams scenario where storage does everything renewable cannot do is not realist with the current technology available excepted in powerpoint bullshit slides.

The discussion is about what should be built, not what has been built. The discussion is about what can be and should be done now to reduce CO2 emission as fast as possible if we do not want get toasted in 20 years. Bcause in 20 years, it is already too late. And the easy answer is built damn nuclear power plants and at the world scale. Not take 20 years to play with techs that are still on the design board: Power2Gas is one of them. And everything else is not scalable in term of storage. > and power to gas has an end to end loss of roughly 50% I do see power to gas as the last desperate attempt of the oil and gas industry to stay relevant in the next decade. Nothing more. For the rest it's a joke. It is a joke in term of investment, it is a joke in term of efficiency, it is a joke in term of economical viability. Hydrogen has its usage, but not as backbone of the power grid.

    If everybody in the room agrees on the benefits, why not spend most of the discussion debating the drawbacks and the contentious points? That’s a very common situation in my professional life.

Things like power to gas would work economically because you buy cheap and sell high. The efficiency figure becomes less important if renewables are cheap and gas is expensive.
