In today’s video, I will show you how to turn water into hydrogen and oxygen to generate HHO gas. In this video, I separate ...

The “petrol from air” technology involves taking sodium hydroxide and mixing it with carbon dioxide before "electrolysing" the sodium carbonate that it produces to form pure carbon dioxide.

Clive Semmens discusses ways to get around obstacles to electrolysing seawater to make hydrogen (Letters, 12 October). But electrolysing a salt solution is the standard way of making bleach.

Xueli Zheng (left) and Dr. Bo Zhang demonstrate their electrolysing device. Their team designed a new catalyst to efficiently split water into hydrogen and oxygen, allowing virtually limitless ...

Why can’t we use seawater to make hydrogen, asks Albert Lightfoot (Letters, 21 September). We can, but corrosion of the anode by chloride ions in seawater is a problem. It isn’t insurmountable ...

Hydrogen produced by electrolysing water, using electricity from solar or wind power projects, is designated ‘green’ hydrogen, and India has been pushing this technology in the past few years.

Green hydrogen is produced by electrolysing water using round-the-clock (RTC) renewable energy. The cost gap between grey and green hydrogen is expected to come down from its current level of $2.0 ...
