H2Pro believes it can slash costs and clean up one of the world’s dirtiest industries.

In the Caesarea industrial zone, an Israeli startup is working on a technology that could help reinvent one of the world’s most polluting industries. H2Pro, founded in 2019 after a chance bus ride conversation between two Technion professors and later led by serial entrepreneur Talmon Marco, is aiming to transform how green hydrogen, hydrogen produced without carbon emissions from renewable energy, is generated.

The means: a fundamental re-architecture of electrolysis, the decades-old process used to produce hydrogen from water. The ambition is bold, streamlining the process enough to drive the cost of green hydrogen down to around one dollar per kilogram, making it competitive with hydrogen produced using fossil fuels.

Today, the world consumes roughly 100 million tons of hydrogen each year, a market worth an estimated $200 billion. “The large hydrogen market today is in refineries, chemical plants, and steel manufacturing, and in the future, jet fuel production,” says H2Pro CEO Tzahi Rodrig. The problem is that hydrogen production accounts for roughly 2.5% of global greenhouse gas emissions.

“About half of the hydrogen used globally goes to ammonia production, and the other half to the oil industry,” says Prof. Gideon Grader, one of H2Pro’s founders from the Technion. “This market creates enormous pollution because of the way hydrogen is produced.”

Most hydrogen today is made using steam methane reforming (SMR), a cheap but highly polluting process that relies on natural gas. The clean alternative, electrolysis, which separates hydrogen from oxygen in water using electricity, has been known for more than a century, but it remains prohibitively expensive.

“The cost of producing hydrogen through electrolysis simply can’t compete with the polluting methods,” says Prof. Avner Rothschild, another Technion professor and company co-founder. The most expensive and problematic component, he explains, is the membrane at the heart of the electrolyser, which separates hydrogen and oxygen gases.

“Our invention challenged something that no one had questioned before,” says Rothschild. Instead of producing hydrogen and oxygen simultaneously, separated by a membrane, H2Pro’s system generates the two gases in separate stages.

In the first stage, one electrode produces hydrogen while the other temporarily stores oxygen. In the second stage, the oxygen is released. “This two-step architecture dramatically reduces costs and complexity,” Rothschild says.

The change required an entirely new type of electrode. “We had to reinvent the electrode, its composition, its structure, everything,” he explains. At H2Pro’s R&D facility in Caesarea, engineers manufacture electrodes from scratch, mixing metal powders and sintering them at temperatures of up to 1,200 degrees Celsius to withstand the harsh operating conditions inside the electrolyzer.

Protecting the technology poses its own challenge. “You can’t protect hydrogen itself, it’s a natural molecule,” says Dr. Revital Green of the Ehrlich Intellectual Property Group. “Once hydrogen is sold, there’s no way to trace its origin. That’s why protection has to focus on the system: the components, their configuration, and how they interact.”

For hydrogen to be truly green, it must be produced using renewable electricity from solar or wind. But those energy sources are inherently volatile.

“Conventional electrolyzers don’t cope well with fluctuations in power supply,” says Rothschild. “They degrade quickly, and that comes at a high cost.”

H2Pro’s system, by contrast, can be turned on and off repeatedly without damage. “Existing electrolyzers can’t handle constant cycling,” says Rodrig. “Ours can.”

That capability allows the system to be connected directly to solar fields. In theory, farmers growing tomatoes or cucumbers could also produce hydrogen on-site and sell it as an additional revenue stream.

“To reach one dollar per kilogram of hydrogen, every cost component has to be attacked,” says Rodrig. “Electricity is the biggest one. At around five cents per kilowatt-hour, the math starts to work.”

Talmon Marco, who chairs the company after selling Viber for $900 million in 2014 and Juno for $200 million in 2017, is cautious about timelines. “A dollar per kilogram is an extremely tough target,” he says. “But reaching a low, economically viable price, probably around 2031, is realistic.”

Marco frames the effort as part of a broader climate solution. “Green energy may be less fashionable right now, but progress is real, especially in China,” he says. “In the end, we’ll have to go where the problem leads us: solving the climate crisis.”

H2Pro has raised more than $100 million from investors, including Bill Gates’ Breakthrough Energy fund and Singapore’s sovereign wealth fund. A 50-kilowatt system is already operating at its Caesarea facility. In February 2026, a 500-kilowatt system is scheduled to go live in Ziporit, near the Sea of Galilee, followed by a much larger system, up to 50 megawatts, in Spain or Portugal.

“There simply isn’t enough green hydrogen today,” says Rodrig. “Even if everyone wanted to switch tomorrow, the supply doesn’t exist. Someone has to build the infrastructure.”

That demand could soon explode. “Aviation wants hydrogen. Shipping wants hydrogen. Heavy-duty trucking wants hydrogen,” he says. “We’re talking about a market that could eventually reach trillions of dollars.”

Cornell Tech hosted the inaugural Disability and Access in Tech and AI Summit on Oct. 9-10 on its Roosevelt Island campus, bringing together researchers, technologists, and community advocates to explore how disability and accessibility intersect with innovation. The summit welcomed speakers, students, faculty, alumni, and community members from Cornell’s Ithaca campus, New York City, and around the United States.
The event, designed to be a space for dialogue, lived experience, and cross-sector collaboration in addition to showcasing research, was co-organized by Omari W. Keeles, senior director for diversity, equity, inclusion, and belonging, and Thijs Roumen, assistant professor of information science at Cornell Tech.

The idea to create the event emerged from conversations across campus and a growing recognition that accessibility deserves a central place in the tech landscape.

“We felt there was a bigger opportunity here,” said Roumen, who is also affiliated with the Bowers College of Computing and Information Science. “The most important outcome is to find one another — those who built technology, those who make policy, and those who use the technology. There is so much we can all learn from one another.”

The event was powered by YAI, a nonprofit organization that supports people with intellectual and developmental disabilities. YAI’s involvement helped ground the summit in real-world impact, connecting Cornell Tech’s academic community with practitioners and advocates working directly with people with disabilities. YAI also co-hosted interactive workshops, including one where attendees could try out assistive technologies and engage with startup founders developing tools for communication and mobility.
In welcome remarks, Keeles began the summit by acknowledging the systemic barriers that have historically excluded disabled voices from tech and academia. “When disabled researchers and practitioners lead and contribute to the development of technology, the outcomes are more responsive, more creative, and ultimately more just,” he said.

The opening keynote was delivered by Shiri Azenkot, associate professor of information science at Cornell Tech, Cornell Bowers, and the Jacobs Technion-Cornell Institute. Azenkot shared her lab’s work on making augmented and virtual reality technologies accessible to people with low vision and other disabilities.

One project involved designing an augmented reality system to help users locate specific products on store shelves, a task that can be frustrating and time-consuming without visual cues. Another explored how blind users could navigate social virtual reality environments using a “sighted guide” avatar they could virtually “hold onto.”

Throughout the summit, panels covered a wide range of topics, each rooted in personal experience and practical application. One session explored the challenges of navigating graduate school while undergoing cancer treatment, highlighting the often invisible nature of disability. Another focused on mental health and disability justice in higher education, with speakers reflecting on how institutions can better support students and faculty with neurodivergence or intellectual disabilities.

A panel on AI and safety examined how emerging technologies can support disabled people across cultures, while another featured startup founders building expressive communication tools for nonverbal users.

The summit concluded with a powerful closing keynote by University of Washington Professor Jennifer Mankoff, a leading researcher in human-centered design and accessibility. Mankoff shared insights from her work on accessibility in AI and the importance of centering disabled voices in technology development.
The event’s hybrid format, in-person on Thursday and fully remote on Friday, reflected this ethos, ensuring broader participation for those unable to travel to New York City and expanding the accessibility of the summit.

Roumen said he hopes the summit will inspire students and technologists to think more deeply about accessibility — not just as a niche concern, but as a universal design challenge.

“I hope more people, even those not directly working on accessibility, take this important demographic into consideration when developing technology and policy,” he said. “This will not only make the world better for people with disabilities, but for everybody else too.”
