Hydrogen has been called the Swiss Army knife of energy, because it has so many potential applications, from home heating to heavy industry. But so far, deployment around the world has been slow. And in recent months there has been a series of setbacks for plans to use clean hydrogen to decarbonise energy systems. So what’s the problem?

Is it unsuitable infrastructure, policy uncertainty, or fundamental challenges of physics and economics? Does hydrogen really have a role to play in the low-carbon energy system of the future? And if it does, what does the industry need to get there?

To find out, host Ed Crooks is joined by Dr Melissa Lott, Partner General Manager in Energy Technologies at Microsoft, and Austin Knight, Vice President for hydrogen at Chevron New Energies.

Hydrogen is not a one-size-fits-all solution, but it could help us tackle some of the toughest challenges in decarbonisation. It may be expensive, but in some sectors it looks like a more cost-effective solution for achieving net zero than any other option.

For some proposed applications, it looks pretty clear that hydrogen is going to be a non-starter. But Austin says there are some sectors where it still has a viable future. Chevron is investing in hydrogen fuel suppliers and fuelling stations for heavy trucks across California, for example. As Melissa says, the infrastructure just isn’t there yet to make hydrogen a viable option today. But is it a case of “if” hydrogen becomes a commercial reality, or “when”? Find out here.
