The most expensive part of making fuel from thin air is, ironically, getting the carbon out of the air. The rest,turning that CO2 into a hydrocarbon with water and electricity,is comparatively straightforward chemistry. So when a startup claims it can slash the energy and cost of that first, punishing step by 90%, it's worth checking the math on the back of a napkin.
Sora Fuel, a Boston-based company spun out of a University of British Columbia lab, is making that claim. Its bet is a proprietary "bicarbonate electrolyzer" that performs direct air capture and conversion in a single, closed-loop system. The company says this integrated approach can capture carbon dioxide for less than $50 per ton, a figure it repeats is roughly one-tenth the cost of conventional DAC [Mintz, May 2026]. The output is syngas, which is then fed into a standard Fischer-Tropsch reactor to produce what Sora calls "100% carbon-negative" drop-in fuels, starting with sustainable aviation fuel (SAF) [Sora Fuel].
The chemistry wedge
Most power-to-liquid fuel pathways follow a sequential script: capture the CO2 (expensive), purify and compress it (more expense), then feed it into a separate reactor for conversion. Sora's core innovation, developed in co-founder Curtis Berlinguette's lab, collapses the first two steps. The process uses a liquid electrolyte to absorb CO2 directly from the air, forming bicarbonate. That solution is then fed into an electrolyzer, which splits the bicarbonate back into CO2 and hydrogen at the electrode surface, producing syngas in one unit [Clean the Sky].
By combining capture and conversion, the company aims to avoid the massive energy penalties of regenerating solid sorbents or compressing pure CO2 streams. "The process uses only air, water, and renewable energy as inputs," the company states [Sora Fuel]. If the efficiency claims hold at scale, the unit economics shift from theoretical to tangible. The target is SAF priced under $5 per gallon, a threshold that begins to whisper about real market displacement [Pulse2, April 2026].
The team building the pilot
The company's leadership reflects a deliberate blend of deep science and industrial scale. The technology originates with Curtis Berlinguette, a professor of chemistry and chemical engineering at UBC, a Fellow of the Royal Society of Canada, and a serial climate tech founder [Wikipedia]. Co-founder and Chief Science Officer Patrick Sarver, a former venture associate at lead investor The Engine Ventures, helped translate the bench science into a company [Axios, August 2024]. CEO Gareth Ross, who previously led digital ventures at MassMutual, handles commercialization and fundraising [Forbes, April 2021].
Recent hires point squarely at the challenge ahead: building heavy hardware. Angie Ackroyd joined as VP of Engineering, bringing over 40 years of experience commercializing complex technologies, including hydrogen product development at Shell [Sora Fuel]. The board added Steve Bolze, the former CEO of GE's $28 billion Power business, who one investor noted "has operated industrial energy at the scale Sora Fuel is aiming for" [Standish Spring Investments].

Funding the path from gallons to barrels
Sora Fuel has raised $20.6 million to date across two seed rounds, a war chest for the capital-intensive climb from lab beaker to pilot plant. A $6 million round in August 2024, led by The Engine Ventures with Wireframe Ventures participating, funded team expansion and early development [Sora Fuel, August 2024]. The larger $14.6 million round in April 2026 was co-led by Spero Ventures and Inspired Capital, with pro-rata participation from existing backers [Mintz, May 2026].
The proceeds from the latest round have a single, clear purpose: build and operate a pilot production facility. The goal is to scale output from gallons to barrels per day, moving from proof-of-concept chemistry to integrated systems engineering [Renewables Now]. The company says it has generated partnership and offtake interest from "leading global energy companies, airlines, and aviation manufacturers," though it has not named them publicly [Mintz, May 2026].
The efficiency gamble
The bet is elegant, but the risks are physical. The company's entire value proposition rests on the unproven-at-scale efficiency of its bicarbonate electrolyzer. The claimed capture cost of "less than $50 per ton" and 90% energy reduction are laboratory results and projections [Mintz, November 2024]. The pilot plant is the first real test of whether those numbers hold when the system is run continuously, dealing with real-world air impurities, thermal management, and the wear and tear of industrial operation.
Furthermore, Sora Fuel is not just building a carbon capture machine, it's building a mini-refinery. The downstream Fischer-Tropsch synthesis, while standard, is itself a complex and capital-intensive process. Integrating two novel systems,the electrolyzer and the fuel synthesis unit,into one reliable, automated plant is a formidable engineering challenge. The company's near-term credibility hinges on demonstrating not just fuel production, but consistent production at a documented cost and energy budget.
What to watch in the next 18 months
The milestones are hardware-shaped. The primary focus is the successful commissioning and operation of the pilot plant, with a key metric being the actual, measured energy consumption per ton of CO2 captured. Investors and potential offtake partners will be looking for third-party validation of the system's performance data. Concurrently, watch for the announcement of a first named strategic partner or fuel offtake agreement, which would signal industry validation beyond venture capital.
A simple calculation illustrates the stakes. The global aviation industry consumes about 100 billion gallons of jet fuel annually. Replacing just 1% with SAF at Sora's target price of $5 per gallon represents a $5 billion annual market. At their claimed $50 per ton capture cost, the CO2 required for that 1 billion gallons would cost roughly $350 million. The math works only if the efficiency claims are real.
For Sora Fuel to matter, it must eventually beat not other DAC startups, but the incumbent it seeks to displace: fossil-derived jet fuel, currently priced around $2-$3 per gallon. The path there is paved with billions of dollars of capital and countless kilowatt-hours. Their first pilot, funded by this $20 million seed, is where that long road begins.
