Synergies of sector coupling and transmission reinforcement in a cost-optimised, highly renewable European energy system — mentioned by Certhas

Please show a single publication that does what you claim it does. A single one. I don't think they exist, or if they do they will not be the prominent highly cited ones. Yes, storage and methanation and electrolysis are expensive. These expenses are explicitly modeled in the energy system models. Modeling these expenses for a complete system that satisfies the security of supply constraints is the very essence of what these models do [1]. Criticism against them would be exactly that they don't assume some market/price dynamics but a perfect central planner. Flexible loads are a fundamentally…

Power2Gas has been a major topic. And the idea that this will become highly relevant in about a decade is behind the idea to allow Gas infrastructure investment as Green in Europe. This means Hydrogen but also synthetic natural gas. https://en.wikipedia.org/wiki/Power-to-gas Methanation and methane storage is at the same level as Hydorgen storage in optimal models. This here has 500 citations: https://arxiv.org/pdf/1801.05290.pdf They also cite something I haven't personally read, but which goes back all the way to 2009, again with hundreds of citations: M. Sterner, Bioenergy and renewable…

Storing methane is cheaper, and you can use it for heating, it brings down costs when used in addition to hydrogen storage: https://arxiv.org/pdf/1801.05290.pdf " 4.7. Methanation scenario - In the Methanation scenario the conversion of hydrogen to methane is allowed, which can then be fed into the natural gas network for use both in the heating and electricity sectors. Since the carbon dioxide required for the methanation is captured from the air, the methanation has a low overall efficiency (60%), but the resulting methane is extremely valuable to meet the peak heating demand.Despite the…

> That's not true and unfair. I believe you are genuine, but also the information you present is miles from the reality in Germany and Europe, and the state of research in the field in general. > Believe it or not, I want to be proven wrong. I want somebody to walk me through what a end-goal for our ideal energy mix is, preferably without casually throwing it that we just need to create a new exotic battery technology. Until 80% the carbon optimal mix is Gas + Renewables. For the last 20% you need to start producing the Gas from excess energy during times when renewables outstrip demand.…

Additional investment in transmission lines and sector coupling is politically more viable and cheaper, and already that is stalled. So I'd rather push for that. (Plus we avoid a massive scale waste problem). Let existing ones run as long as possible, and if China or other countries want to go for the nuclear option, great! I'm simply objecting to the idea that that's the only/easiest/optimal option. The variability of renewables is of course a well studied problem [1] and exactly why, after a certain point, we need transmission capacity (or, more expensive, local storage). The variability…

Could you please point me to reputable studies that back up your claim that storage will be needed before very high penetration? Even for extremely high carbon reductions (95% on 1990) the best models I've seen consider transmission lines and sector coupling considerably cheaper. And these models make very aggressive assumptions on the fall of battery prices. E.g.: https://arxiv.org/pdf/1801.05290.pdf Edit: The thing to look at is figure 11. on page 16. It gives a policy trade off. Given political limits on the amount of transmission grid extension (x axis) what is the cost of the…
