Power-to-gas technologies are advancing. Power-to-gas involves energy losses in the conversion, but the power of gaseous energy that it is much cheaper to store than electricity, plus the distribution networks largely exist already. | Power-to-gas technologies are advancing.

Researchers from [[w:Purdue University|Purdue University]] have developed [https://pubs.acs.org/doi/10.1021/acssuschemeng.8b03841 a technology entitled 'Use of Supercritical Water for the Liquefaction of Polypropylene into Oil'] that works on [[w:polyolefin|polyolefin]] waste, the sort of plastic used for [[w:grocery bag|grocery bag]]s, [[w:toy|toy]]s, and [[w:shrink wrap|shrink wrap]]. This sort of plastic accounts for about 23% of [[w:plastic waste|plastic waste]], according to researchers who describe the process in a paper published in Sustainable Chemistry and Engineering, a publication of the [[w:American Chemical Society|American Chemical Society]]. The new technique uses a process called [[w:hydrothermal liquefaction|hydrothermal liquefaction]], in which very high temperatures melt pellets of polyolefin and then dissolve them in [[w:water|water]]. The by-products of this process are [[w:oil|oil]], [[w:gas|gas]], or [[w:solvent|solvent]]s.<ref>https://www.technologyreview.com/f/612935/a-new-chemical-process-could-turn-a-quarter-of-our-plastic-waste-into-clean-fuel/</ref> | |||
