Arbor Energy and Resources

Rocket engineering for power generation. Next-generation turbines. Clean firm power.

[Arbor Energy and Resources @ArborEnergyCo]

We’re hiring a Senior Thermodynamics Performance Engineer to own the steady-state and dynamic models of Arbor’s direct-fired supercritical CO₂ cycle. You’ll run the studies before each test campaign and refine the models with each round of test data, building toward a full simulation of the system that our controls engineers can work from.

The role suits someone who has modeled demanding thermal-fluid systems, whether in nuclear thermal-hydraulics, rocketry, gas turbines, or high-performance turbomachinery. If you want to apply that experience to bringing clean, firm power online for a world that needs a lot more of it, find the role here: https://t.co/JNVYSXU5pQ

If you’ve wondered how Arbor turns natural gas into clean, firm power, this is the simplest place to start.

In this short, plain-English walkthrough, our COO @Alicia_AERC follows the energy through Arbor’s power system, from fuel burning in pure oxygen inside the oxy-combustor to the supercritical CO₂ turbomachinery that generates electricity.

Lots of people have reached out asking if Tuesday's election was good for Lowercarbon and if it's safe to say clim**e again?

So @Sacca, @caiekelley, and I compared notes. Tl;dr: if your investment thesis depends on who wins an election, you might want a better thesis: https://t.co/jEZwkzI5wr

@scaryjellomj @IanRountree Have made** sCO2 work 😉

[ian @IanRountree]

Lots of $$ going into turbine startups and more renders to go with them.

Meanwhile Arbor (@ArborEnergyCo) is testing their 1MW sCO2 system and scaling up to 25MW in 2027. Apply if you want to build time-to-power with a bunch of former SpaceX and GE engineers.

[Alicia Harmon @Alicia_AERC]

Just ran these numbers...
58.6 year cumulative experience building high efficiency gas turbines at GE
77.8 years cumulative experience building turbines and rocket engines at SpaceX
170+ years cumulative experience directly designing AND building high performance engines and propulsion systems
390 (!!) years cumulative experience building industrial plants and processes

Truly ridiculous. Find me a team with a more credible connection between power-generation rigor and rapid, integrated propulsion development. 😆

[Alicia Harmon @Alicia_AERC]

Heatwaves raise demand at the same time they reduce the output of conventional thermal plants. Air-breathing gas turbines lose capacity as inlet air density falls, so the hours when power is most valuable are often the hours when nameplate capacity is least available.

That is one of the lesser-discussed reasons @ArborEnergyCo power cycle is such important technology—a closed system whose output is largely impervious to the rising and increasingly unpredictable temperatures that force everyone else to derate.

The next generation of power turbines will need to deliver firm capacity that holds up under the conditions we are actually seeing, not just the conditions we used to design for.

@leobanchik Having partners like you and @VoyagerVC who understand what it takes to build something this ambitious makes all the difference. Here's to the journey ahead—and building an industrial power giant together!

[Arbor Energy and Resources @ArborEnergyCo]

@mackhopen @IanRountree Can confirm Kai is one of the best

[Arbor Energy and Resources @ArborEnergyCo]

@kdpisda @IanRountree Our system produces ~34 MW gross and delivers 25 MW net, after accounting for the ASU and other internal loads.

[Arbor Energy and Resources @ArborEnergyCo]

What better way to introduce ourselves than through this brilliant explanation of what we're building from @IanRountree. Ian and @cantos wrote Arbor's first check and have been backing us ever since.

Grateful for our supporters and excited for the big announcements to come! 🚀

Is Arbor Energy the key to power AND water for data centers? They just cracked the code to supercritical CO2 turbines, which have been something of a holy grail in power generation, especially in Arbor's case, because:

1. Using sCO2 as a working fluid can achieve energy efficiency rivaling large combined cycle gas plants in a much smaller footprint––e.g. behind the meter at data centers. No one had pulled it off though because it requires engineering a system capable of withstanding immense pressure, temperature, speed, and corrosion. Until now!

2. Combining this with oxycombustion of natural gas (CH4) means the outputs are only CO2 (used, recycled, and/or sequestered) and water. Arbor's power modules will PRODUCE tons of water while powering data centers... a MILLION gallons per megawatt, to be exact. So not only will their 25MW Halcyon system power data centers, it can ELIMINATE their water burden and even produce surplus water for local communities!

3. The key components can be 3D PRINTED! You've surely heard of the bottleneck in gas turbines, which is primarily due to the way in which combined cycle turbine blades must be produced (single-crystal casting).

I'm extremely proud that @cantos was Arbor's very first investor and has invested in every round since then. Watch this company!
