You know the saying "building a plane while flying it"? My guest this week on @cleaninguppod.bsky.social is Tim Meyerjürgens, CEO of Tennet Germany. He's building the grid of the future while keeping the lights on & the power flowing in much of Germany. A masterclass. www.youtube.com/watch?v=PQgU...

Thanks @rustneversleeps.bsky.social! As a business builder. I have never thought the way to beat climate change was "just stop oil". You have to build the alternatives, which means factories, supply chains, skills, capital formation, etc which takes time. Great to see my little model catching on.
Listening to @volts.wtf recent panel/podcast with @mliebreich.bsky.social , discussing his "Pragmatic Climate Reset", published in two parts at BNEF last September.
Michael mentioned his "simplest energy model ever" - just 4 parameters - and I decided to sketch up and add emissions and temps.

I'm impressed at how patient @mliebreich.bsky.social was in this debate.
The economic viability of the hydrogen economy relies upon everything else being more expensive so it can compete.
Meanwhile renewables, battery storage & direct electrification are already cheaper than Fossil Fuel Systems.

The average hydrogen share price fell 90% between January 2022 and April this year. It is now down only 89%. According to Erik Rakhou, this tiny dead cat bounce is evidence of the dawn of the Hydrogen Economy. What do you think? Listen to the debate: youtu.be/FSWDgNWeVjk?...

Green hydrogen as a hedge against gas price shocks? Puh-lease. European gas prices exceeded a €5/kg hydrogen-price-equivalent for only 141 days after Russia's invasion of Ukraine, and a €10/kg price for just 13 days. You don't pay €5-10/kg for 25 years for fear of a spike lasting a few weeks.
