Arbor’s ‘Vegetarian Rocket Engine’ Power Plant Goes Omnivore
A bold new chapter is unfolding for Arbor Energy’s groundbreaking innovation — the so-called ‘vegetarian rocket engine’ power plant, now turning into an omnivore. What began as a clean-energy project fueled solely by plant waste is evolving to include natural gas, blending flexibility with carbon-conscious design.

Founded by former SpaceX engineers, Arbor originally set out to build a carbon-negative power system that removed CO2 from the atmosphere by burning biomass. The plant’s unique oxy-combustion technology earned it the nickname “vegetarian rocket engine” — a nod to its plant-based fuel and rocket-inspired engineering.
From Vegetarian to Omnivore: A Strategic Shift
Arbor Energy recently raised $55 million in Series A funding, led by Lowercarbon Capital and Voyager Ventures. The fresh capital supports the company’s pivot from a purely biomass-based design to one that can also utilize natural gas.
This shift isn’t a move away from sustainability but a response to soaring electricity demands — especially from AI data centers. While biomass sources like wood and agricultural waste remain sustainable, they are limited in availability. Natural gas, though not plant-based, offers consistent supply and scalability.
How the ‘Vegetarian Rocket Engine’ Power Plant Works
The system relies on oxy-combustion, a process that converts hydrocarbons into syngas and then burns it with pure oxygen. The result is a clean, concentrated stream of CO2 that’s easier to capture and store underground.
According to Arbor spokesperson Patrick Mahoney, storing the CO2 will actually be cheaper than releasing it, thanks to federal tax credits for carbon sequestration. Arbor remains committed to only partnering with businesses that intend to capture or reuse the emitted CO2 — not release it back into the atmosphere.
Meeting the AI Energy Surge Responsibly
AI and cloud computing are driving massive increases in electricity consumption, pushing energy providers to innovate faster. Arbor’s hybrid approach could position it as a reliable, cleaner power source for data centers that need consistent uptime without compromising sustainability.
By combining biomass and natural gas, Arbor’s ‘vegetarian rocket engine’ power plant delivers a balance between eco-friendly operation and grid stability — a crucial factor as renewable demand outpaces infrastructure.
Addressing Methane and Carbon Challenges
Despite its innovations, the move to include natural gas raises environmental questions. Methane, the primary component of natural gas, is 84 times more potent than CO2 in trapping heat over 20 years. Arbor’s technology aims to neutralize this impact through carbon capture, but the overall climate benefits will depend on how effectively methane leaks are prevented during extraction and transport.
Experts suggest that if Arbor maintains rigorous capture standards, the system could outperform conventional gas plants while remaining more scalable than biomass-only models.
A Glimpse at the Future of Hybrid Clean Energy
Arbor’s evolution highlights a growing trend: hybrid energy systems designed for both flexibility and environmental responsibility. Its “omnivorous” model could inspire other companies to blend renewables with transitional fuels while maintaining carbon-capture integrity.
As global energy demands rise, especially from AI infrastructure, Arbor’s ‘vegetarian rocket engine’ power plant stands as a symbol of adaptive innovation — one that redefines what clean energy can look like in a data-driven era.
