Talk:Power-to-X

Note for reviewer
Please note the article has been the subject of discussion: review of submission. Please note that the topic of power-to-X does not lend itself to a simple redirection because it bundles two concepts (see introduction). -- RobbieIanMorrison (talk) 20:21, 3 May 2016 (UTC)

"Power-to-heat" and "Power-to-mobility" seem forced, they're Demand response
Power-to-heat and power-to-mobility are just "uses of electric power". You can heat space and water and charge BEVs when electricity is plentiful/renewable/cheap, but everything I've read in English names that Demand response and they're mentioned in that article (which doesn't mention "Power-to-X" or "P2anything" at all). To unfairly stereotype, these terms may be a Germanic attempt to create an overarching naming scheme for every way of dealing with fluctuating renewable electricity; but it's not even a complete list since it ignores space pre-cooling and nobody seems to use the term "Power-to-cooling"/P2C.

I've separated them out in the introduction, but left their descriptions in the body of the article under "Sector coupling concepts" alone. A more aggressive approach would be to remove much of the text under "Sector coupling concepts" and instead refer to Demand response, but that article doesn't use the terms "power-to-mobility" and "power-to-heat", doesn't cleanly separate them out, and reads like a research paper focused on the electrical grid rather than an encyclopedia article on novel intermittent uses of electricity. -- Skierpage (talk) 20:59, 17 September 2020 (UTC)


 * Demand response is focusing on the electrical system only. What are the effects on the power consumption? From a DR point of view you can do anything including wasting energy to shape the demand curve. It is of course better to have an option which uses most of the exergetic value of the energy. Thus, a merit order of marginal utility is needed on the non-electric side, or some kind of functional electricity storage. --Gunnar (talk) 22:11, 2 December 2020 (UTC)

Sector coupling
Power-to-X is a one way direction, whereas sector coupling (more precisely the plural: sectors' coupling) is a back and forth exchange between different sectors. The coupling of different sectors is easy, as "sectors" are markets. Retail markets for electricity (household sector + commercial), wholesale markets for electricity (industry sector, electricity sector), markets for transportation fuels (transportation sector), markets for heating oil and natural gas (heat sector). These are easy to couple, just by connecting the trading platforms with an IT link. Actually what we want to do is the coupling of infrastructures. Networks for electricity, network for gas, and networks for heat - this needs much more time and CAPEX. --Gunnar (talk) 22:11, 2 December 2020 (UTC)
