INTERVIEW: Emvolon sees renewable marine and aviation fuel demand for waste-gas methanol

The global biofuels industry spends much of its time debating feedstocks such as used cooking oil, animal fats and agricultural residues, but one of the largest untapped resources is already being produced and burned off, Emmanuel Kasseris, CEO of Emvolon told Platts.

"US landfill gas stock is about 300 billion cubic feet and most of it is flared because there is no pipeline nearby," said Kasseris, co-founder and CEO of Emvolon.

His company, an MIT spinout, has developed a system that converts methane-rich waste gases directly into methanol at the source, using modular reactors built around repurposed automotive engines. Instead of transporting gas through expensive pipelines, Emvolon converts it into a liquid fuel that can be moved by truck, rail or barge.

The biomethanol startup has signed a definitive agreement under which trader Freepoint Commodities will receive a first-purchase option for biomethanol and associated liquid fuels produced by Emvolon's waste-methane conversion projects.

Production volumes are designed to scale to 300,000 metric tons/year as Emvolon's project portfolio expands, a deal which the companies said could exceed $450 million in seven years.

The approach targets landfills, dairy operations, agricultural digesters and industrial flare sites — locations where methane emissions often have limited economic value due to a lack of infrastructure.

"Instead of building a centralized plant that really relies on economies of scale, this is built so that it can have totally mass production," Kasseris said.

The company's technology repurposes mass-produced 10-liter to 20-liter combustion engines as methanol synthesis reactors. By relying on standardized equipment rather than bespoke chemical plants, Emvolon aims to reduce deployment costs and accelerate project development.

Economics drive deployment

While the engineering is unusual, Kasseris argues that the economics ultimately matter.

He said projects can achieve payback periods of roughly four years and internal rates of return above 20%, largely because the feedstock is methane that would otherwise be flared or stranded.

"In terms of IRR, that is more than 20%," he said.

The company believes its decentralized approach can compete with conventional methanol production by eliminating major infrastructure costs associated with pipelines and large centralized facilities.

Why methanol?

Kasseris sees multiple end markets for low-carbon methanol.

Marine fuel is among the most immediate opportunities, with hundreds of methanol-capable vessels already operating globally and shipping companies seeking lower-carbon alternatives to conventional bunker fuels.

Chemical markets also offer demand, particularly as manufacturers seek lower-carbon feedstocks.

In the long term, Kasseris believes aviation could become an important outlet.

"This year, as you know, we finally have the ESDM certification for methanol jet," he said. "We are actually working very actively to secure some partnerships in that space."

While aviation remains a longer-term opportunity than marine fuel or chemicals, he argues methanol's relative ease of production could make it an attractive route for future SAF supply chains.

Scaling up

The challenge now is moving from demonstration to deployment.

Emvolon is developing its first commercial projects through a partnership with Montauk Renewables, with the first unit expected to be online in the first half of 2027. Additional projects are expected to follow as the company builds out a larger network of methane-to-methanol facilities.

A recently announced agreement with Freepoint Commodities provides both an offtake pathway and access to project-level financing, helping address one of the biggest hurdles facing emerging fuel technologies: commercial scale-up.

For Kasseris, the broader opportunity extends beyond methanol itself.

The goal, he said, is to create a practical way of turning waste methane emissions into tradable liquid fuels without waiting for new pipelines, new power lines or entirely new infrastructure networks.
