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 work, we argue 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 electro-technologies, 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, e.g., by linking it to H2 production. Below, we review selected electrochemical technologies crucial for a future sustainable society. Significant further development of these technologies within the next decade is needed, though, to meet the ambitious climate goals.
