SOLIDEC.

Chemicals shouldn't come on trucks. Solidec makes them on-site from air, water, and electricity - starting with the hydrogen peroxide the world already runs on.

Solidec - on-site chemical production technology

SOLIDEC, HOUSTON. A box the size of an appliance, doing the work of a chemical plant. Point clean electricity at air and water; peroxide comes out the other side. No smokestack in the frame - that's the point.

The Story

A chemical plant, shrunk to the size of the problem.

Walk into most factories that use hydrogen peroxide and you'll find the same ritual: a tank, a delivery schedule, a safety data sheet, and a truck that rolled in from a plant hundreds of miles away. Solidec's pitch is that the truck is the bug, not the feature.

Conventional peroxide is born in giant centralized plants through the anthraquinone process - fossil-fuel-fed, capital-heavy, and then shipped as a hazardous liquid across the country. Solidec looked at that supply chain and asked a quieter question: what if the chemical never had to travel at all?

The answer came out of Rice University, from the lab of chemical engineer Haotian Wang. His group spent years on a porous solid-electrolyte reactor - a device that pulls molecules like oxygen and carbon dioxide out of the air and, with nothing but water and electrons, rebuilds them into useful chemicals. In 2023, three people decided that reactor belonged on factory floors, not just in journals.

How It Works

Three cheap inputs. One useful output.

The whole model fits in a sentence: feed the reactor the most abundant things on Earth, let electrochemistry do the assembly, collect the product where you'll use it.

& MORE

The same reactor architecture can co-produce hydrogen peroxide and sodium hydroxide from air, water, and salt - and, with different settings, formic acid, acetic acid, and ethylene.

What They Build

One platform, a shelf of chemicals.

Flagship

On-site Hydrogen Peroxide Generator

An autonomous, low-maintenance electrolyzer that makes ultra-pure H₂O₂ on demand for disinfection, bleaching, water treatment, and odor control - using far less energy than legacy production.

Core Tech

Porous Solid-Electrolyte Reactor

The engine of the company: it captures gaseous molecules like CO₂ and O₂ and converts them into chemicals and fuels, skipping the centralized plant and the post-processing steps.

Roadmap

Modular Multi-Chemical Reactors

Reactors designed to produce many widely used chemicals - formic acid, acetic acid, ethylene - on-site, replacing brittle supply chains with local generation.

NASA SBIR

Space-grade Electrolyzer

A peroxide-producing reactor for onboard disinfection and water treatment on long-duration missions - the same box, now cleared for orbit.

We're particularly excited about Solidec's ability to produce many different widely used chemicals.

The Founders

Three people, one stubborn idea.

A water-infrastructure researcher, an electrolyzer engineer, and the Rice professor whose lab started it all.

RD

Ryan DuChanois

Co-Founder & CEO

Clean-water researcher turned founder. Sustainability master's at Cambridge, engineering PhD at Yale, postdoc at Rice, and an Activate Fellow.

YX

Yang Xia

Co-Founder & CTO

Electrolyzer and molecular-extraction expert. B.S. from Northwestern, PhD in chemical engineering from Rice.

HW

Haotian Wang

Co-Founder & Chief Scientist

Associate Professor at Rice. 90+ publications, 30,000+ citations, and the 2025 Norman Hackerman Award in Chemical Research.

Why It Matters

The invisible 40%.

The chemical and petrochemical sector accounts for roughly 40% of US industrial carbon emissions - hiding inside products almost nobody thinks about. Solidec starts there, at the boring, enormous middle of the economy.

Deletes three carbon shadows at once: the plant, the truck, and the storage tank.
Up to 90% lower emissions per unit of chemical produced.
No hazardous freight, no delivery schedules, no supply-chain volatility.
Runs on electricity - which gets cleaner every year on its own.

The Long View

Back to the factory floor.

Return to that factory. The tank is still there, but the delivery schedule is gone. The truck that used to roll in every few weeks isn't on the calendar anymore, because the peroxide is being made a few feet from where it's used - out of air, water, and whatever electricity is on the grid that day. The safety data sheet is thinner. The carbon math is different. Nothing about the product changed; everything about how it arrived did. That's the whole company, sitting quietly in a box in the corner.

What you can do with it: replace trucked-in hydrogen peroxide with on-site generation for water treatment, disinfection, bleaching, and odor control.
Who it's for: industrial and commercial chemical buyers who'd rather make than ship - and, per NASA, spacecraft that can't ship at all.
