Cement manufacture is a huge carbon emitter. A by-product of splitting seawater might make the process more environmentally friendly.

In addition to producing hydrogen, seawater electrolysis can also precipitate minerals such as calcium carbonate (CaCO 3) and magnesium hydroxide (Mg(OH) 2), both of which are useful in construction, ...

When applying voltage or current to seawater during seawater splitting, or electrolysis ... Deposits of carbon-trapping minerals such as calcium carbonate and magnesium hydroxide—which have ...

However, tweaking the electrolysis conditions could turn this unwanted by-product reaction into a valuable new way to produce calcium carbonate. This is not necessarily a new idea, as CaCO3 as well as ...

A Cornell-led collaboration has hit the trifecta of sustainability technology: The group developed a low-cost method to ...

Researchers have made a groundbreaking paste that could help create carbon-capturing concrete in new construction projects.

that occur naturally in seawater. The reaction produced solid minerals, including calcium carbonate and magnesium hydroxide. Calcium carbonate directly acts as a carbon sink, while magnesium ...

Equatic is designing what it says will be the first commercial-scale, ocean-based plant for carbon removal ... Equatic’s method centers on seawater electrolysis. This technique uses electric ...

The researchers discovered that PET-based glitter microplastics can actively promote the crystallization of calcium carbonate (CaCO 3) minerals in seawater. Their experiments revealed that the ...
