As First State Hydrogen continues to advance its groundbreaking clean hydrogen production facility in the U.S., the spotlight intensifies as hydrogen becomes an increasingly key player in the energy transition.

With the projected uptick of new hydrogen production and handling projects, let's explore hydrogen fire protection, reflect on the measures and standards established to mitigate risks, and ensure that the hydrogen economy thrives.

The challenges of hydrogen fire protection

As the hydrogen industry experiences a boom, the issue of fire protection emerges as a critical concern. It's important to note that hydrogen fires can pose a significantly higher risk than traditional fuel fires, burning hotter and more rapidly due to their higher outflow rates. The diverse range of storage and transport options, from cryogenic liquids to high-pressure cylinders, further complicates safety measures. This underscores the industry's urgent need to prioritize risk mitigation for common hydrogen applications, such as high-pressure cylinders used in fuel-cell vehicles and data centers, to ensure safety as this energy source scales up.

Hydrogen jet fire test results

The author's company, a global leader in paint and coatings, recently tested an industry leading, flexible epoxy intumescent passive fire protection (PFP) coating to evaluate the material response against high pressure hydrogen jet fires to determine if current ISO jet fire standards are adequate for the challenges hydrogen poses. Collaborating with the United Kingdom's Health and Safety Authority, they conducted hydrogen jet fire tests at a specialized facility. The team replicated conditions of high-pressure hydrogen leaks and their effects on steel and protective coatings. The initial tests revealed unprotected steel reaching critical temperatures rapidly under hydrogen fires. The steel coated with advanced PFP coatings proved highly effective. The PFP coatings help keep steel well below critical temperatures throughout the exposure, indicating their potential to protect against structural failures during hydrogen fires.

These initial tests can contribute to setting standards for hydrogen fire protection. The results offer safety experts critical data for better protecting industrial environments against high-pressure hydrogen jet fires.

A call for a fire protection standard

The hydrogen industry currently relies on oil and gas regulations for specialized fire protection. While safety experts actively debate whether these standards can be adapted or whether entirely new criteria are necessary, industry collaboration remains key. Paint and coating companies, international standard organizations, safety groups, and energy regulators are all actively involved in assessing the adaptability of existing standards for hydrogen fires. The initial tests show promising results, suggesting that current oil and gas fire protection measures might be adapted for hydrogen fire protection, potentially leading to standards for the growing hydrogen industry.

Developing fire protection standards for the hydrogen industry remains a collective industry responsibility. Safety engineers, industry specialists, non-government officials (NGO), and policymakers must work together to ensure the hydrogen industry advances safely and responsibly. The paint and coatings industry, in particular, will play a crucial role in creating these standards. Leveraging their expertise in protective coatings, they can meet hydrogen's unique needs, from anti-corrosion to chemical resistance and passive fire protection.

Houston expert discusses the clean energy founder's paradox

Guest Column

Everyone tells you to move fast and break things. In clean energy, moving fast without structural integrity means breaking the only planet we’ve got. This is the founder's paradox: you are building a company in an industry where the stakes are existential, the timelines are glacial, and the capital requires patience.

The myth of the lone genius in a garage doesn’t really apply here. Clean energy startups aren’t just fighting competitors. They are fighting physics, policy, and decades of existing infrastructure. This isn’t an app. You’re building something physical that has to work in the real world. It has to be cheaper, more reliable, and clearly better than fossil fuels. Being “green” alone isn’t enough. Scale is what matters.

Your biggest risks aren’t competitors. They’re interconnection delays, permitting timelines, supply chain fragility, and whether your first customer is willing to underwrite something that hasn’t been done before.

That reality creates a brutal filter. Successful founders in this space need deep technical knowledge and the ability to execute. You need to understand engineering, navigate regulation, and think in terms of markets and risk. You’re not just selling a product. You’re selling a future where your solution becomes the obvious choice. That means connecting short-term financial returns with long-term system change.

The capital is there, but it’s smarter and more demanding. Investors today have PhDs in electrochemistry and grid dynamics. They’ve been burned by promises of miracle materials that never left the lab. They don't fund visions; they fund pathways to impact that can scale and make financial sense. Your roadmap must show not just a brilliant invention, but a clear, believable plan to drive costs down over time.

Capital in this sector isn’t impressed by ambition alone. It wants evidence that risk is being retired in the right order — even if that means slower growth early.

Here’s the upside. The difficulty of clean energy is also its strength. If you succeed, your advantage isn’t just in software or branding. It’s in hardware, supply chains, approvals, and years of hard work that others can’t easily copy. Your real competitors aren’t other startups. They’re inertia and the existing system. Winning here isn’t zero-sum. When one solution scales, it helps the entire market grow.

So, to the founder in the lab, or running field tests at a remote site: your pace will feel slow. The validation cycles are long. But you are building in the physical world. When you succeed, you don’t have an exit. You have a foundation. You don't just have customers; you have converts. And the product you ship doesn't just generate revenue; it creates a legacy.

If your timelines feel uncomfortable compared to software, that’s because you’re operating inside a system designed to resist change. And let’s not forget you are building actual physical products that interact with a complex world. Times are tough. Don’t give up. We need you.

Houston maritime startup raises $43M to electrify cargo vessels

A Houston-based maritime technology company that is working to reduce emissions in the cargo and shipping industry has raised VC funding and opened a new Houston headquarters.

Fleetzero announced that it closed a $43 million Series A financing round this month led by Obvious Ventures with participation from Maersk Growth, Breakthrough Energy Ventures, 8090 Industries, Y Combinator, Shorewind, Benson Capital and others. The funding will go toward expanding manufacturing of its Leviathan hybrid and electric marine propulsion system, according to a news release.

The technology is optimized for high-energy and zero-emission operation of large vessels. It uses EV technology but is built for maritime environments and can be used on new or existing ships with hybrid or all-electric functions, according to Fleetzero's website. The propulsion system was retrofitted and tested on Fleetzero’s test ship, the Pacific Joule, and has been deployed globally on commercial vessels.

Fleetzero is also developing unmanned cargo vessel technology.

"Fleetzero is making robotic ships a reality today. The team is moving us from dirty, dangerous, and expensive to clean, safe, and cost-effective. It's like watching the future today," Andrew Beebe, managing director at Obvious Ventures, said in the news release. "We backed the team because they are mariners and engineers, know the industry deeply, and are scaling with real ships and customers, not just renderings."

Fleetzero also announced that it has opened a new manufacturing and research and development facility, which will serve as the company's new headquarters. The facility features a marine robotics and autonomy lab, a marine propulsion R&D center and a production line with a capacity of 300 megawatt-hours per year. The company reports that it plans to increase production to three gigawatt-hours per year over the next five years.

"Houston has the people who know how to build and operate big hardware–ships, rigs, refineries and power systems," Mike Carter, co-founder and COO of Fleetzero, added in the release. "We're pairing that industrial DNA with modern batteries, autonomy, and software to bring back shipbuilding to the U.S."

Shell Global Solutions International, a subsidiary of Shell, which maintains its U.S. headquarters in Houston, has signed a collaboration agreement with London-based Supercritical Solutions to advance Supercritical’s ultra-efficient hydrogen electrolyzer technology toward a field pilot demonstration.

In the deal, the companies will collaborate on a paid technology feasibility study that will support the evaluation and planning of the pilot demonstration, according to a news release. Supercritical Solutions’ technology aims to deliver high-efficiency renewable hydrogen at a lower cost for the industrial hydrogen market.

"Signing this collaboration agreement with Shell is a major milestone for Supercritical Solutions and an important step on our commercialisation journey,” Luke Tan, co-founder of Supercritical, said in the news release. “We are directly addressing the cost and complexity barriers facing the renewable hydrogen market. We are excited to move forward with a company like Shell, whose global leadership has been proven to accelerate innovative technologies to market.”

Supercritical’s hydrogen electrolyser technology can operate at high temperatures and pressures of up to 220 bar without the need for an external hydrogen compressor, rare-earth materials or easily degradable membranes. The technology removes the typical compression step in the process while delivering hydrogen at industry standards. It requires significantly less energy than many traditional electrolyzers and is more cost-efficient.

This recent investment builds on an ongoing relationship between Shell and Supercritical. Supercritical was founded in 2020 and was runner-up in Shell’s New Energy Challenge, which helps startups and scaleups develop sustainable technologies, in 2021. Shell Ventures then invested in Supercritical’s Series A funding round in 2024 with Toyota Ventures.
