Hydrogen is having a moment in Southern California. The first element on the periodic table is rapidly emerging as a green alternative to natural gas. But for every hydrogen battery, electrolyzer or pipeline being proposed, a sensor is required: Hydrogen gas, as you may remember from high school chemistry class, is extremely flammable.


For H2scan, there’s big money in not blowing stuff up en route to a greener economy. On Tuesday, the Valencia-based hydrogen sensor company unveiled a $70 million capital raise that will be used to develop its technology, expand its manufacturing and bolster its sales and marketing operations. U.K.-based investment group LetterOne led the funding alongside South Korean energy company GS Energy. (H2scan also announced David Meyers, a former executive at engineering consulting firm Altran, as its new chief operating officer on Tuesday.)

H2scan’s sensors consist of a palladium-nickel crystal lattice that traps individual hydrogen molecules; when hydrogen binds to the palladium, it causes the electrical resistance of the lattice to change. With the help of algorithms, that change in resistance can be used to calculate exactly how much hydrogen is moving through the sensor—and whether it’s approaching dangerous levels.

“Because of our patented technology, where it's lower cost and more reliable and more accurate, we feel that puts us in a prime position to be the number one go-to—the golden standard for hydrogen sensing in the world,” H2scan founder, president and CEO Dennis Reid told dot.LA. “The bottom line is we want to be in every pipeline, we want to be in every electrolyzer and we want to be in every home. And we feel that we now definitely have the capital to get there.”

Founded in 2002, the company went to market with its hydrogen sensors in 2012 and has since deployed more than 20,000 units for applications including petrochemical refineries, nuclear facilities, semiconductor manufacturing, plastics production and food sciences. (H2scan’s customers include ExxonMobil, Shell, Chevron, Procter & Gamble, Siemens and ABB.) Reid is quick to note that they’ve never had a single sensor fail.

One growing area that will certainly need quality hydrogen sensors in the future is pipelines. Last week, Southern California’s primary gas utility, SoCalGas, revealed its plans for a hydrogen pipeline system as part of its goal to fully decarbonize its operations by 2045.

As energy companies increasingly turn to hydrogen, “There will be new safety requirements for avoiding an accident, because the hydrogen will very likely be mixed with some other gasses to avoid risky situations,” according to Jerzy Szpunar, a professor of mechanical engineering at the University of Saskatchewan who studies hydrogen generation and storage.

Reid says that H2scan’s sensors are particularly well-suited for pipeline applications due to their ability to pick out hydrogen molecules against a background of other compounds. In addition to expanding its production facility in Valencia, H2scan will also use the new funding to reduce the manufacturing cost of its sensors by consolidating many of the supporting electronics into a dedicated circuit—a move that could bring the price per sensor down from around $9,000 to just $2,000 for some applications.

Making hydrogen power more affordable is key to California’s transition to clean energy, and H2scan wants to be at the center of the conversation, according to Reid. “We want to take our core technology and then create a product for every single application within the hydrogen economy,” he said.

⚖️FTC’s "Click to Cancel" Rule and Its Ripple Effect on Tech

🔦 Spotlight

Happy Friday Los Angeles,

The FTC’s new “Click to Cancel” rule is shaking up subscription-based tech. Now, instead of navigating a maze of cancellation hurdles, users can cancel subscriptions as easily as they signed up—with a single click. This shift is a wake-up call for SaaS, streaming, and app-based companies, where once-hidden exit options often kept users around simply because canceling was a hassle.

The rule also requires businesses to send regular renewal reminders, ensuring customers stay informed about upcoming charges. It's more than a cancellation button—it’s about transparency and giving users control over their decisions.

For startups, the impact goes deeper than UX adjustments. Many have relied on "dark patterns," which subtly discourage cancellations by hiding the exit. Now, companies must shift toward building genuine loyalty by delivering real value, not by complicating exits.

While this might affect retention rates initially, it could lead to more sustainable business models that rely on satisfaction-driven loyalty. Investors may start prioritizing companies that emphasize transparent, long-term engagement over those that depend on dark patterns to maintain retention metrics.

The rule opens the door to more ethical UX design and a truly user-centered approach across the tech industry. It may even set a precedent against manipulative design in other areas, such as privacy settings or payment methods.

Ultimately, the “Click to Cancel” rule presents an opportunity for the tech industry to foster trust and build stronger customer relationships. Startups and established companies that embrace transparency will likely stand out as leaders in a new era of customer-centric tech, where trust—not tricky design—is what retains users.

As the tech landscape continues to evolve, LA Tech Week 2024 offers a chance to explore these shifts in real-time. Check out the upcoming event lineups to stay informed and make the most of your time:
