About us

At Arbor, we’re sustainably powering the present while erasing emissions of the past. Our innovative system transforms organic waste into clean, reliable electricity while capturing carbon dioxide at scale. Founded by space tech veterans who pivoted from building technology to explore new planets to protecting our own, Arbor leverages cutting-edge aerospace technology to tackle climate change. Our mission is to bring gigawatts of clean, dependable baseload power online while removing gigatons of legacy carbon emissions. Earth is the most important spaceship we’ll ever have, and we’re dedicated to restoring its balance. Drawing on our team’s deep aerospace expertise, we’ve created a power system that meets today’s demands while repairing yesterday’s damage. Arbor’s engine, fueled by organic waste, improves on Bioenergy with Carbon Capture and Storage (BECCS) using advancements in oxy-combustion, supercritical turbomachinery, and additive manufacturing. The system turns waste—like overgrown brush, crop residues, and food waste—into clean power, reducing wildfire risks and landfill emissions. The captured CO2 is permanently stored deep underground, where it mineralizes into rock, ensuring it never returns to the atmosphere. At Arbor, we envision a future where human progress and environmental stewardship work in harmony to power our world and bring the planet into balance. We’re proudly backed by climate-focused investors including Gigascale Capital, Voyager Ventures, Lowercarbon Capital, and Cantos Ventures.

    Meet Sutton Guldner, Head of Business Development at Arbor Energy 👋 With deep roots in energy and a drive to tackle climate change at industrial scale, Sutton is helping transform waste biomass into carbon-negative power. Here's his story: 🏗️ Tell us about your career path. "In college I had no idea what I wanted to be, I just knew I was good at solving problems so figured I might as well start with mechanical engineering. I'm the 3rd generation of my family in the oil field—my dad had a 42-year career with Chevron, grandfather with Foster Wheeler. That got me started with Schlumberger, and eventually to installing equipment for Shell offshore. After switching to Shell's biofuels team, I learned projects often failed not due to technical reasons, but organizational and business considerations. After projects turned sour back-to-back, I spent the pandemic in Business School. Coming out of my MBA, I wanted to join the earliest climate hardware company I could find—that's when Arbor found me." 🚀 What's surprised you most about climate tech? "The diversity of people's backgrounds. At Shell most folks were Mechanical or Chemical engineers. In climate tech, way more engineering disciplines are represented, plus non-engineering ones too. At Arbor, most of our engineering talent is from aerospace. I've been surprised by how humble folks can be and willing to challenge their own notions. Everything changes so fast, people love to learn the most up-to-date information.” 🌱 What drew you to climate tech? "I'm from Houston. As the energy capital of the world, nothing is drilled into you more there than 'energy is the bedrock of society'. But few cities are also more a sign of our current energy mix's downsides. Last year it was over 100F every day in August. The city gets hit by worse hurricanes and deluges that don't grab headlines but cause tons of damage. The Texas freeze of 2021 singlehandedly spurred me to learn more about electric grids than any other force in my life. A quick trip through Houston's Ship Channel refineries shows you the solution has to be more intense than just recycling and lowering your thermostat." 💪 What keeps you motivated when challenges arise? "Ultimately the size and scale of the problem, and the knowledge that even failures and mistakes are learnings for the industry. Beyond climate change being an existential threat, I focus on what we can impact today—the massive amount of organic waste in this country and the need for renewable baseload solutions. Driving through Texas, I see overgrown forests desperate for thinning while local biomass facilities close down. These communities need local, baseload power—unlocking biomass with new tech could help them take charge of their energy future." Interested in joining Sutton for a career in climate?

  • Our hearts are heavy as we witness the devastation caused by the fires here in Los Angeles. The Arbor team is based in El Segundo (a tight-knit community in LA) and we’ve seen incredible response from the ESFD on the frontlines. We’re heartbroken by the destruction and loss these fires bring to the neighbors, wildlife, and landscapes that define our home. For our CEO Brad Hartwig, wildfires are deeply personal. As a search-and-rescue specialist (both with Marin SAR and the California Air National Guard), witnessing the devastating effects of CA wildfires served as a turning point in his life that inspired Arbor—changing his mission from reaching for the stars to protecting the planet we all call home. As engineers, scientists, and climate advocates, we work every day to create solutions that honor that same purpose: safeguarding the Earth and its ecosystems. But today, we simply want to extend our deepest compassion to those affected and our gratitude to the firefighters and first responders risking everything to protect our communities. If you’re looking for ways to support, we encourage donations to local relief efforts or organizations like the California Community Foundation’s Wildfire Relief Fund. We remain committed to the vision of a world where we build more sustainable solutions to prevent these tragedies from becoming the new normal. Stay safe, LA. We’re with you.
