🔍 Episode Summary:

Is green hydrogen the silver bullet for decarbonisation — or a trillion-dollar distraction?

In this episode of Saving the World from Bad Ideas, Mark Lynas is joined by energy analyst, investor, and podcaster Michael Liebreich to unpack Bad Idea #24: “We’ll just use Hydrogen!”

Liebreich, founder of Bloomberg New Energy Finance and co-host of the Cleaning Up podcast, makes the provocative case that green hydrogen is over-hyped, fundamentally flawed as a fuel, and destined to remain a niche solution rather than the backbone of a “hydrogen economy.”

Together they explore the physics, economics, and politics of hydrogen — why hype keeps returning in 20-year cycles, what role hydrogen can play in industry and fertilisers, and why pragmatism, not techno-fantasy, must drive climate strategy.

🧠 Topics Discussed:

● 💧 Why hydrogen is a “really crappy fuel” — and the laws of thermodynamics make it costly

● 📉 The difference between green, blue, grey, turquoise, and pink hydrogen

● 🏭 Current global hydrogen use: 100m tonnes/year, and why 0.1% is green ● 🚢 Why shipping liquid hydrogen is nearly impossible (density, leakage, energy loss)

● 💸 Hydrogen’s “missing trillions”: the cost gap with grey hydrogen

● 🛩️ Europe’s RED III mandate and the looming cost inflation in aviation fuels

● 🚛 Why trucks, steel, and shipping are unlikely to go hydrogen

● 🔋 The rise of electric trucks, batteries, and the hydrogen ladder framework

● ⚖️ Pragmatism vs. hype: why chasing bad ideas risks a climate backlash

● 🐢 The “Pragmatic Climate Reset”: think like a tortoise, not a hare

“If you care about the climate, the cleanest kilo of hydrogen is the one you never make.” — Michael Liebreich

“For every $1/kg cost gap, hydrogen needs $100 billion per year in subsidies. That’s the missing trillions.” — Michael Liebreich

“Politicians love hydrogen because it’s a get-out-of-jail-free card. But hype doesn’t change physics.” — Michael Liebreich

“Think like a tortoise, not like a hare: go steady, pragmatic, and win the race.” — Michael Liebreich
