Abstract
Unprecedented increase in atmospheric CO2 levels calls for efficient, sustainable, and cost-effective technologies for CO2 removal, including both capture and conversion approaches. Current CO2
abatement is largely based on energy-intensive thermal processes with a
high degree of inflexibility. In this Perspective, it is argued that
future CO2 technologies will follow the general societal
trend towards electrified systems. This transition is largely promoted
by decreasing electricity prices, continuous expansion of renewable
energy infrastructure, and breakthroughs in carbon electrotechnologies,
such as electrochemically modulated amine regeneration, redox-active
quinones and other species, and microbial electrosynthesis. In addition,
new initiatives make electrochemical carbon capture an integrated part
of Power-to-X applications, for example, by linking it to H2
production. Selected electrochemical technologies crucial for a future
sustainable society are reviewed. However, significant further
development of these technologies within the next decade is needed, to
meet the ambitious climate goals.
