Abstract
At a glance
Turning carbon dioxide from a waste stream into a useful feedstock is a compelling scientific and engineering goal. This editorial surveys the opportunity while keeping energy inputs, conversion efficiency, and system-level climate value in view.

Carbon as a feedstock
Captured carbon dioxide can be converted into fuels or chemical intermediates, creating a possible route for storing renewable energy in molecular form.
The chemistry is only the first question. The source of carbon, hydrogen, and process energy determines whether the pathway provides real climate value.
The energy balance
Conversion requires substantial energy, and losses accumulate across capture, synthesis, transport, and final use. Low-carbon electricity is therefore a core input, not a background assumption.
Catalyst performance, product selectivity, and process integration will shape which applications are practical.
A systems-level answer
CO₂-derived fuels may be most useful where direct electrification is difficult and carbon molecules remain operationally valuable.
Transparent lifecycle boundaries are essential. The goal is not merely to recycle carbon, but to reduce net emissions across the whole system.
