Renewable electricity storage using electrolysis

Electrolysis converts electrical energy into chemical energy by storing electrons in the form of stable chemical bonds. The chemical energy can be used as a fuel or converted back to electricity when needed. Water electrolysis to hydrogen and oxygen is a well-established technology, whereas fundamental advances in CO2 electrolysis are still needed to enable short-term and seasonal energy

Electrochemical Capture and Release of Carbon Dioxide

Understanding the chemistry of carbon dioxide is key to affecting changes in atmospheric concentrations. One area of intense interest is CO 2 capture in chemically reversible cycles relevant to carbon capture technologies. Most CO 2 capture methods involve thermal cycles in which a nucleophilic agent captures CO 2 from impure gas streams (e.g., flue gas), followed by a thermal process in which

Is aluminium electrolysis using inert anodes a blind

In a future scenario in which an investor has the choice between conventional electrolysis technology and the use of inert anodes, only the best technologies will be considered. A comparison of cells with inert anodes with the best Hall-Hroult technologies thus still remains the correct approach.

Electrolyzer overview: Lowering the cost of hydrogen

2020/3/26Smolinka estimates that the production of a membrane-electrode unit – the heart of a PEM electrolysis cell – accounts for 60% to 70% of the total cost, while pure material costs – including the expensive precious metals – account for only 30% to 40%.

Vermiculite clay mineral as an effective carbon paste

A vermiculite modified carbon paste electrode (VMCPE) was employed for the in situ preconcentration of traces of Hg(II) and Ag(I) via an ion-exchange route. Heavy metal ions were accumulated in Britton-Robinson (BR) buffer pH 7 for Hg(II) and pH 6 for Ag(I), and afterwards reduced at –0.7 V vs. Ag/AgCl in the separate measurement solution (BR buffer pH 5 + 0.05 mol/L NaNO3) prior to the

Review—Electrochemical CO2 Reduction for CO

2020/2/14Recently, the field of CO 2 electrolysis has experienced rapid scientific and technological progress. This review focuses specifically on the electrochemical conversion of CO 2 into carbon monoxide (CO), an important building block for the chemicals industry. CO 2 electrolysis technologies offer potentially carbon-neutral routes for the production of specialty and commodity chemicals.

Address the "alkalinity problem" in CO2 electrolysis with

Sustainable transformation of CO2 into chemicals (CO2RR) is promising for renewable energy conversion. Recently, alkaline flow cells have been extensively used for CO2RR because of their high performance; however, continuously flowing bulk alkaline electrolyte is ultimately not sustainable. We highlight catalyst design as a fruitful approach to address this issue, by enabling favorable
