Full Steam Ahead The story of steam, and the opportunity it poses for electrification and decarbonization.

Honored to write for ASME on how the legacy of the steam boiler helped inspire Boiler 2.0 and AtmosZero’s mission.

Thanks to Louise Poirier, @jeffreywinters.bsky.social for their editorial support & the invitation.

Porting bangers over from Twitter

Another day of boring 24/7 boiler operation at a customer site.

It ain’t much, but it’s honest work.

The story of steam Steam production hasn’t evolved much in a century. Heat pumps, electric furnaces, and thermal storage could change that.

Steam powers much of the modern world—but it’s largely missing from climate conversations. I joined ‪@catalyst-pod.bsky.social to unpack the role of steam in industry, the challenges of electrifying it, and why it’s finally getting attention.

We need targeted policies, not blunt tariffs, to drive “American energy dominance” Trump should strive to support innovation in the energy industry, and that’ll take more than erecting costly trade barriers.

AtmosZero's @addisonkstark.bsky.social weighs in on Trump's tariffs in @technologyreview.com, arguing that raising costs and rankling our trade partners isn't the way to drive the energy sector forward.

Decided to throw in on the tariff discourse with an energy dominance twist.

Was great working with @jtemple.bsky.social and the @technologyreview.com editorial team.

New in @technologyreview.com : We need smart, targeted tariffs—not blunt trade wars—to win the race for energy dominance.

Let’s put America’s workforce to work building batteries and heat pumps, not toasters.

Real.

Climate Group Funded by Bill Gates Slashes Staff in Major Retreat Breakthrough Energy, an umbrella group for energy and environmental efforts funded by Mr. Gates, is resetting for the Trump era.

Wow.

Feels like a big mistake given how effective this team was in maintaining momentum during the first Trump admin that resulted in Energy Act 2020 among other great wins from 2016-2020.

Investor focus is on heavy industry due to the challenge that it poses in the coming decades, but light industry where the rubber is meeting the road.

Happy that our focus on light industry is being recognized by BloombergNEF.

Between steel tariffs, Canadian import tariffs and OPEC pushing down global prices, it’s been a tough week for American Energy Dominance.

Most heat pumps that produce steam need a source of heat at 30°C. The AtmosZero uses ambient air, potentially down to -20°C. This demonstrates it works at -13°C #decarbonization

key is we do not focus on capturing waste heat for waste heat's sake, rather focus on capex minimization and delivery of thermal amenities, both hot and cold.

yes. we can source air or water with an easy swap and drop-in integration in either case. We also have a configuration where we are able to simultaneously deliver steam and chilling to a facility simultaneously where they have both hot and cold chain to manage.

Thanks, Jesse! We will be releasing a full analysis of the runs on different temperature days and different steam temp deliveries in the spring after we complete a full testing regime.
But this was too good to pass up showing now!

On a cold Colorado morning the AtmosZero team turned on Boiler 2.0 and happened to do something that has never been done before.

All in a day's work.

Here’s hoping!

Now we're cookin'.

Thrilled to see my former ARPA-E colleague and friend, Conner Prochaska, tapped to lead the agency.

I mean this is fine. “Resilience” speaks more to action than the passive “change”.

And as some more backing for second point (no need for heat pumps above ~225C)… that’s where thermal storage like Rondo/Antora/ETS/etc really start to emerge as the key competitor and winner above 300C. With conservative e- price assumption thermal storage beats HP due to low COP at that temp
