Themed collection Carbon capture, storage or utilisation – Topic Highlight

Electrochemical technologies support the transition towards carbon-neutral chemical manufacturing and we need new approaches to accelerate electrolysis scale-up.

Hydrogen (H₂) production along with CCUS (carbon capture, utilization, and storage) are two key areas for transition to net-zero emission. Carbon-neutral liquid e-fuels produced from H₂ and captured CO₂ are practical alternatives to fossil fuels.

This study reports a comprehensive analysis of the operation of a biogas methanation system with a total 240 kW SNG output.

Next step forward towards green steel! A pilot plant integrated into a steel mill has been operated successfully and shows promising results. This novel, retrofitted process for steel production has the potential to cut global CO₂ emissions by 0.5%!

Permeability distribution imposes substantial control over CO₂ flow path, in situ temperature changes, and fluid pressure propagation in offshore geologic storage of CO₂.

Electrowetting leads to flooding of silver-based, carbon-free gas diffusion electrodes for CO₂ electrolysis.

Enhancing CO₂ capture through conjugated microporous polymers.

Electrochemical conversion of CO₂ to C₁ and C₂₊ chemical synthons using a 2D Ti₃C₂T_x catalyst in benign aqueous electrolytes.

The influence of bond polarity on the thermochemical redox properties of a series of cation substituted perovskite oxygen carriers is reported.

The relationship between porosity within a given pore size range, and uptake of CO₂ as a function of pressure.

We use quinone reduction potentials to showcase molecularly tunable CO₂ binding strengths for a family of electrochemically generated quinoid molecular sorbents. In our study, we find that CO₂ binding stoichiometry varies with CO₂ concentration.

We investigate how different CDR options—afforestation/reforestation (AR), bioenergy with carbon capture and storage (BECCS), and direct air carbon capture and storage (DACCS)—might be deployed to meet the Paris Agreement's CDR objectives.

A new combined chemical looping process makes use of any gas stream containing CO₂ and fuel to produce carbon monoxide without external energy input. Carbon monoxide can be used for producing a variety of carbon-based products.

Ionic liquid-based aqueous electrolytes with reduced IL content for coupling CO₂ capture and electrochemical reduction.

Direct activation of biomass, via a simple and lower cost one-step process, with potassium oxalate as a mild and less corrosive agent, yields activated carbon with properties and CO₂ uptake comparable or superior to conventionally prepared activated carbons.
