Correction to: Nature Energy https://doi.org/10.1038/s41560-021-00937-z, published online 25 November 2021.

In the version of this article initially published, there was an error in the symbol key to Fig. 1c and Extended Data Fig. 1. The labels corresponding to green diamonds and circles, and purple diamonds and circles, were in error and have been reordered top-down to appear as “1.5C-Conv,” “1.5C-Elec,” “WB2C-Conv” and “WB2C-Elec”, respectively. The changes have been made to the HTML and PDF versions of the article.
