Question: What is a possible alternative to making carbon-based fuels from reduction of carbon dioxide?
Sentence: The multielectron catalytic chemistry involved in making carbon-based fuels (such as methanol) from reduction of carbon dioxide is challenging; a feasible alternative is hydrogen production from protons, though use of water as the source of electrons (as plants do) requires mastering the multielectron oxidation of two water molecules to molecular oxygen.
Answer in sentence: yes
