Eugene Beh

Quino Energy makes a redox flow battery. Strip away the jargon and it is two tanks of liquid and a stack in the middle where the electricity happens. The liquid is water with quinones dissolved in it - organic molecules, the same chemical family that shows up in rhubarb and in your own cells shuttling energy around. Pump the liquid through the stack one way and it stores charge. Pump it the other way and it gives the charge back. Want more storage? Build a bigger tank. The power and the energy are decoupled, which is exactly the trick the grid has been waiting for.

This matters because the grid has a clock problem. The sun sets. The wind drops. Demand peaks at dinner. Lithium-ion handles a few hours and then taps out, and when it fails it tends to fail spectacularly - thermal runaway, the kind of event that makes the evening news. Beh's pitch is unglamorous and therefore credible: a battery that is cheap to scale, made from a domestic supply chain, and physically incapable of catching fire because the active ingredient is organic chemistry floating in water.

The chemistry did not start in a garage. It started in two Harvard labs run by professors Michael Aziz and Roy Gordon, where a young postdoc named Eugene Beh spent 2015 to 2017 coaxing water-soluble molecules into storing electrons without falling apart. Years later he came back, licensed the work, and turned it into a company. He is now, by his own quiet admission, a chemist who has somehow ended up running a factory.

Beh grew up in Singapore, and the early signal was loud. As a student he won the National Science Talent Search and not one but two Tan Kah Kee Young Inventors' Awards - prizes handed to kids who build original things rather than merely answer questions correctly. Before any of the chemistry came two and a half years of mandatory military service, the Singaporean rite of passage that has a way of teaching patience to people who would rather be in a lab.

Then came the long academic march. Harvard for his bachelor's and master's in chemistry, finished in 2009. Stanford for the PhD - which means he holds degrees from both ends of one of academia's oldest rivalries and presumably keeps quiet about it at reunions. His self-description of the arc is refreshingly plain: "My background is in organic chemistry and then later on, I became interested in electrochemistry." That second sentence is where the whole career turns. Organic chemists know how to build molecules. Electrochemists know how to move electrons. Put them in one head and you get someone who can design a molecule specifically to hold a charge.

He is, the record notes, multilingual and has lived across several countries. The throughline is less geography than appetite: a person who keeps wandering toward the harder version of the problem.

Between the Harvard postdoc and Quino, Beh spent roughly five years at Xerox PARC, the legendary Silicon Valley lab where the computer mouse and the graphical interface were dreamed up decades before the rest of us caught on. There he invented and commercialized a redox flow desalination technology - using the same flow-cell instincts not to store energy but to pull salt out of water. The work was good enough that PARC named him its Most Prolific Inventor in 2020 and again in 2021, and the desalination platform was later spun out as its own company, Mojave Energy Systems.

Here is the telling part. Most people, having earned the title of most prolific inventor at one of the most storied labs on Earth, would stay and collect patents. Beh left. He walked away from the comfortable research-staff chair to commercialize the battery chemistry he had helped invent years earlier - betting on a harder, lonelier path because he kept seeing the same thing nag at him.

Beh founded Quino Energy in 2021 with co-founder Meisam Bahari, a fellow Harvard postdoc who became the company's CTO, and with professors Aziz and Gordon as scientific advisors and co-inventors. Harvard's Office of Technology Development granted Quino an exclusive worldwide license to commercialize energy storage built on the quinone chemistry. The company launched publicly in October 2022 and almost immediately landed a $4.58 million Department of Energy grant to figure out how to actually manufacture the stuff.

Manufacturing was always the real frontier. A clever molecule that you can only make a teaspoon of is a paper, not a product. Quino's answer is a single-step, zero-waste, continuous-flow process - and, in a detail that makes industrial chemists raise an eyebrow, it can start from coal-tar-derived reactants. A fossil byproduct goes in one end; clean-energy storage material comes out the other. In late February 2024 the pilot line switched on and quickly cleared 20 kilograms of finished quinone material per hour, with plans to multiply that output fivefold and run multi-megawatt-hour demonstrations on the way to utility-scale deployments in the latter half of the decade.

By the company's most recent funding round, Beh had raised a total of $31.85 million, including a Series A. The headquarters sits in San Leandro, California, a modest address for an outsized ambition: to become the boring, dependable, fireproof workhorse of a grid running on wind and sun.

What stands out about Beh is not flash. It is patience pointed at a single target. He maintained the Harvard relationships for years before they became a company. He spent a half-decade quietly out-inventing everyone at PARC. He picked a technology whose payoff lands in the 2026-2027 utility deployments rather than next quarter. In an industry addicted to the announcement, he keeps building the thing the announcement is supposed to be about.

The gratification, when it comes, is small and physical and real. Watching a molecule he sketched on a whiteboard pour off a production line as a finished product - "It's incredibly gratifying," he said. For a man who has spent his life closing the gap between the lab and the world, that pour is the whole point.
