Solar power and batteries are becoming cheap and ubiquitous. Great. But there are problems batteries can’t solve – like fueling ships and planes. One way to solve those problems: Use solar power to create hydrogen, and turn that hydrogen into fuel.

Today’s guest is Raffi Garabedian, the co-founder and CEO of Electric Hydrogen. Raffi’s problem is this: How do you turn solar and wind energy into clean hydrogen that’s cheap enough to compete with fossil fuel?

This is the last of three episodes we’re doing about the solar-power revolution. Listen to the previous episodes on your podcast player or at our website: https://www.pushkin.fm/podcasts/whats-your-problem

In the past 20 years, the price of solar panels has fallen by more than 97 percent. This extraordinary decline is good news for the world – and it’s transforming the way energy is produced and consumed.

For the next few episodes, we’ll be talking to people who are in the middle of this solar power revolution to find out how it happened, and what it will mean for the world.

Today, Jenny Chase, the author of Solar Power Finance Without the Jargon, tells the story of how solar power got so cheap and where it’s exploding today, and she explains what problems we still need to solve to pull off a worldwide energy transition.
