Cutting Through the Hydrogen Hype
What are the applications with real potential, and what is just hot air?
What is the go with hydrogen these days? Everyone is talking about it all of a sudden! It is literally the most abundant element in the universe, and also plentiful on earth, making up 2/3 of the atoms in water and present in vast volumes of organic compounds. Hydrogen was first produced artificially in 1671 and discovered as an element in 1766. It has been quietly going about its business for hundreds of years before suddenly a couple of years ago, people started to pay attention. It is fair to say that right now hydrogen is having a bit of a moment!
I love a new technology. Pretty much any new technology gets me excited. But I will admit I am a little bit confused and conflicted about hydrogen.
The current hydrogen hype is about “green hydrogen.” That’s hydrogen produced from green electricity in a process called electrolysis. Making hydrogen from electricity is not an innovation, this process has been around for over 200 years, but hydrogen produced in this way is rare, making up less than 0.1% of current global hydrogen production. The other 99.9% comes from fossil fuel sources (“blue”, “grey” or “brown” hydrogen). The vast majority is produced from natural gas…
