I spent years telling the stories of people who built the future. Now I build it.

Hydrogen projects. A hydrogen division inside a 65-year-old industrial company. A legacy chemical business. Three companies, one job: Make it real. Make it run.

01 · Now

Three companies. Three different stages of building.

One develops the project. One supplies the systems that make it work. One is a legacy business where the work is making every order run cleaner than the last.

Cofounder

Total Hydrogen Development

We develop hydrogen fueling, production, and power projects across North America, as the lead developer or alongside another.

  • Originate, structure, build, scale. We find the site and the offtake, structure the project, contract the build team, and stay for operations.
  • Announced: Tom's Truck Center, Santa Fe Springs, California. San Bernardino International Airport, San Bernardino, California.
  • The move: from editing someone else's project to directing our own.

Sales Manager

Total Hydrogen Solutions

A division of Pneumatic and Hydraulic Company. I built the commercial side of its hydrogen business, which became the company's fastest-growing branch.

  • The starting point: I joined in August 2023 to start the hydrogen division. Within the first two years it closed the largest sale in the 65-year-old company's history.
  • What we sell now: complete refueling, production, and power generation stations. Production, compression, storage, fueling, and fuel cell power.
  • Behind it: 40+ OEM, supplier, and direct distribution relationships and 230,000+ sq. ft. of manufacturing in Houston, Texas.
  • The models: techno-economic models for stations from 0.5 to 15 tonnes per day.
  • See what I've built in hydrogen

Co-Owner

Hardt Chemical

A legacy chemical sourcing and supply business serving the energy, plastics, and commodities industries. My job is operational efficiency.

  • Every route written down. Each vendor-to-customer order path documented as a procedure anyone on the team can run.
  • Systems over memory. Orders, invoicing, shipping, and payables moved onto shared tools, with a lean remote team running them day to day.
  • The point: decades of know-how that used to live in people's heads now lives where the business can use it.

02 · How I got here

Five stops. One blend that kept changing.

Storytelling, partnerships, finance, operations, technical. Every stop took a different blend. The job stayed the same: help serious technical work find the people and the money it needs.

03 · Hydrogen

A growing map of what I've built in hydrogen.

From 2018 to 2025 I was part of a hydrogen startup, HNO International, building hydrogen small and scrappy: borrowed lab space, tiny teams. I was CTO, then stepped back to technical advisor so I could help build what came next.

Every project connects to the parts of the hydrogen chain it touched. Projects that share a stage share a bond. Click any project to open its note, with photos and video underneath.

    04 · The people

    The people who showed me what building looks like.

    For years I made films about scientists and inventors whose work we now use every day. I went in to tell their stories. I came out knowing what it takes to build something that lasts. Pick a thread.

      05 · What I believe

      A few things I learned along the way.

      1. 01

        Stop editing. Start producing.

        For years I shaped what someone else had produced and directed. It taught me what to build and how. Now I start the project.

      2. 02

        Returns outlast goodwill.

        Impact funded by someone's spare money lasts as long as their feelings do. A project that returns its capital keeps going on its own.

      3. 03

        Nobody owns energy.

        No country, no company, not me. The work is harnessing it well, and it isn't zero-sum. There's room for a lot of people to do this well.

      4. 04

        The sequence beats the molecule.

        Projects rarely fail on the equipment. They fail on the order of things: site, power, permits, incentives, build. Same lesson as the edit suite.

      5. 05

        Operations is the impact.

        A great story gets attention. A great machine gets installed. Only a business that runs, every order and every day, changes anything.

      6. 06

        Conduit, not source.

        Get out of my own way. Drop the fear and the selfish ambition. If wealth moves through the work, it should move to others first.
