Hello and welcome to the programme.

Net Zero by 2050.

You might call it a goal, a good idea, an imperative, but you also might see it as a breathtaking

business challenge.

To meet it, we have so much to do in 30 years and so much to discover

about how to do it. We're going to see companies come and go, technologies fly and flop,

experiments from the wacky to the wild, we'll see pioneers and buccaneers. Who knows,

who will be king of post-carbon, the new Amazon or the Google, who conquers all. Well, that's not

quite a subject today, but we are going to talk about hydrogen, for which there is all to play

for in the decade to come. Everybody agrees. Hydrogen has a place in the post-carbon economy,

but who will make it? How? And for what uses?

And I have three guests who are doing exciting things in the world of hydrogen. Let's

briefly meet them. Then we'll talk about hydrogen generally before we hear very specifically

about what their companies are doing. My first guest, Eugene McKenna, from the

chemical giant Johnson Mathy. He's managing director of the company's green hydrogen business.

Eugene, just give us a very brief introduction to Johnson Mathy as opposed to the green hydrogen bit

of it. Johnson Mathy, it's a 200-year-old British company, historic roots in platinum group metals.

That's six metals that cluster together in the periodic table.

People will be most familiar with platinum and palladium.

A lot of the business has grown out of finding uses for those materials.

We're being involved in hydrogen right from the start.
