Correction to: Nature Energy https://doi.org/10.1038/s41560-020-0550-8, published online 17 February 2020.

In the version of this Review Article originally published, in Fig. 3a, the second instance of ‘0’ on the x axis (on the right) was incorrect, and should have been ‘14’; in Fig. 4b, on the x axis, the value of ‘1’ should have been ‘10’; and in Fig. 5b, on the y axis of the top graph, the second instance of ‘2,000’ (from bottom to top) should have been ‘3,000’. All versions of the Review Article have been corrected.
