Tenth Anniversary of the LH2 Era™ Blog


The first post made in the LH2 Era™ Blog was on February 18th of 2016, and this post is the 115th on the topic of liquid hydrogen (LH2) systems. There is certainly online content that has been around much longer, but I'm not aware of any existing blogs exclusively focused on LH2 that are older than this one.


While a decade of articles on LH2 is something to personally celebrate (along with my 66th birthday this month :), it does pose a bit of a challenge for readers. Sorting through 115 articles to find a specific topic of interest, or even knowing where to start reading for a deeper dive, is not an easy task.


In an attempt to help with that, I've collected all those blog articles into one searchable 288-page archive document and sorted them into eight sections:

1. Vision, Evolution, and Foundations
2. Technology and Engineering Fundamentals
3. Safety, Training, and Workforce
4. Architectures, Systems, and Operations
5. Sector-Specific Applications
6. Analysis, Modeling, and Software Tools
7. Market Insights and Global Policy
8. Business News and Highlights

There is also a mind map at the end of the document showing interrelationships between the primary topics. Here's a few links to get more details and access to it:
  • Table of contents, other front matter, and mind map: H2 Sage (free; see last two documents in the "Liquid Hydrogen" section)
  • Full document download, updated monthly: LH2 Era™ Library (annual subscription that also includes all training courses and webinar videos and downloads)*

* Most of my content is free access to accommodate students and others with limited funds. However, platforms like Vimeo where this document and other training materials are hosted charge for their service, so a subscription fee helps defray the associated expenses.

The Founder's Journey: 8 Key Questions


I've worked with more than a thousand technology-based organizations so far in my engineering and entrepreneurial career. Some for many years, others for only a day or two. Several hundred of them have been consulting clients, with probably close to half fitting the U.S. Small Business Administration (SBA) definition of a small business entity.

One of the advantages of reaching my 66th birthday this month is having had a long time to observe recurring patterns and archetypes among all those organizational interactions. One fundamental truth is that every business is in one of three states at any given time: growth, decline, or stagnation. 

Business cycles, technology disruptions, and a host of other variables all have an effect on what state a business is in. But in my experience the largest determinant is the leadership team - particularly if the founders are still running the show in the case of small businesses.

Here are the eight key questions that founders have to answer along the way that have an outsized impact on the trajectory of their company. These are based on both my observations of other founders, and my personal experiences as a serial entrepreneur.*

#1: Why Are You Founding a Company?

People start companies for a variety of reasons. There is only one that results in a sustainable business: you (and your co-founders if you have any) can provide something that others need, want, and will pay for that results in a net profit for your business. Beyond that, the ability to scale and protect your competitive advantage will make the difference between thriving versus surviving.
  • Good Signs: The Venn diagram of your core skills, passion, and market need overlap to the extent that you can't stop yourself from trying.
  • Red Flags: You are thirsty to get rich, want to show everybody how successful you are, are running away from an unpleasant career situation, think you have the best idea ever with no validation, and a host of other bad reasons that will generally not end well.

#2: Who Are Your Co-Founders?

Start-ups can waste valuable time coming up with a business name, playing the "C" title game, and deciding how many shares each co-founder gets. The only co-founders you should ever start a business with are ones who have critical skills, experiences, resources, and knowledge that you don't have. Their impact must be exponential not just additive.
  • Good Signs: Your team is always accelerating with the pedal to the floor in ways and with results you didn't think was possible.
  • Red Flags: You keep debating who should be the C-whatever-O and who should be in charge of what.

#3: Where Are You Aiming?

Where are you planning to do business, focused on what products, and to which customer segments. If you can't answer that question with validated customer data, don't quit your day job. Make your core offering as narrow as possible. Start-ups that think they can be everything to everybody never get out of the gate.
  • Good Signs: Customers are coming to you asking how quickly they can get your products or services before asking how much it will cost them.
  • Red Flags: You can't fill out a simple business canvas model that describes how your company works.

#4: How Do You Raise Funding?

There are a variety of ways to fund a new enterprise and they all come at a cost. Some examples in the order of how much control you will retain (most to least): bootstrapping, bank loans, angel investment, and venture capital. Think very carefully before taking the "friends & family" route unless you don't value those relationships. And never max out a bunch of credit cards to fund your start-up if you don't like the idea of eating cat food and living in your car when you can't pay them off.
  • Good Signs: You're bootstrapping from services and other revenue streams while simultaneously collecting customer verification data for your target business model. 
  • Red Flags: You're spending all your time working on pitch decks and lining up investor meetings, and then bullshitting answers to their questions because your business idea is half-baked (or just plain sucks).

#5: Are You Growing a Business or Your Ego?

This one needs to be answered on a continual basis. The "genius with a bunch of helpers" syndrome is legion in the start-up and small business world. If you can't put the vitality of your business ahead of your ego it will never reach its potential. Nor will those helping you to run and grow it (see next question).
  • Good Signs: You are never the smartest person in the room, and you spend most of your time in service to what your team and business needs to succeed. 
  • Red Flags: If you often think (or worse, say out loud) "I'm the only one who can do this" or "nobody else gets what we're doing here".

#6: What Kind of Culture Are You Enabling?

Choose your carrots (incentives) and sticks (disincentives) carefully, and modify them quickly when unintended consequences or counterproductive behaviors arise. Lead by example. Your leadership behavior will mold the business culture more than anything else. Words and other business "comms" are ignored and eventually reviled if they don't match leadership behavior.
  • Good Signs: Your team brings you bad news knowing you will appreciate their candid feedback and provide the support they need to get things on track.
  • Red Flags: No one makes a decision without your explicit consent because you haven't provided them with the requisite authority that matches the accountability you've burdened them with.

#7: When Can Your Company Run Without You?

In the long run, your ultimate goal as a founder is to work yourself out of a job, ideally with a good exit or succession plan. Hire, support, and provide career development and growth for your team members. Then reward their results and help them find the best path to reach their highest potential within your business. Otherwise, they will become demotivated and the most valuable individuals will leave.
  • Good Signs: You continue to find more time to think strategically and enjoy activities and personal relationships outside of the business because you hired and promoted people more capable than you.
  • Red Flags: You believe you are the only one who can run your company properly and have made it a self-fulfilling prophecy by denying anyone the opportunity to prove you wrong.

#8: Are You Making the World Better?

Otherwise, what's the point? We all have a limited lifetime with an unknowable end point. When our time is up, the only thing that remains of real importance is the impact we've had on others.
  • Good Signs: When your company is mentioned in the media, you are generally eager to share it with anyone and everyone.
  • Red Flags: At non-business gatherings you hope that no one asks what you do for a living.

Postscript


This article summarizes a few lessons I learned as a serial entrepreneur since 1995, along with decades of working with and for many organizations of all types and sizes.

One of the many pithy quotes attributed to Mark Twain is "History Doesn't Repeat Itself, but It Often Rhymes". In addition to this article, let me share a story that seems to be very closely rhyming with the AI market right now.

In late 1998, a startup company wanted to license one of my electronics thermal management NASA patents. They invited me to join them on customer discovery meetings with several Silicon Valley heavyweights to explain my technology. We received great feedback during our visits with HP, Intel, AMD, Apple, and Stanford University.

The company founders had backgrounds in investment banking, IBM engineering and marketing, and LIGA microsystems fabrication expertise. Our west coast visits helped to firm up draft term sheets from several of the most well known Sand Hill Road venture capital firms. The stock market was on fire and we were ready to jump in and make our mark.

A few months later, the dot com bubble burst and there was blood in the financial streets and huge holes in every investor's portfolio. Venture capital firms were clawing back whatever they could from grossly overvalued vaporware companies in their portfolio and shredding term sheets.

The fiber optic cable infrastructure had been so overbuilt that ~90% was unused for most of the next decade. No one got any funding for new big idea ".com" startups for quite awhile either. Of course, the major paradigm shift that internet hardware, software, and business models represented eventually occurred several years after the dot com carnage.

Timing is everything, but you will only know if you got it right in hindsight. There are many start-up variables that you cannot control or even predict. So it's best to control the ones you can to improve your odds. I hope this article helps with that, especially for the new generation of technology disruptors.

The Mobility Space Race: 7 Surprising Truths About LH2



1. Anthropocene Effects and Liquid Hydrogen Solutions

The climate data for 2023 was a wake-up call for the planet: global surface temperatures spiked to 1.18°C above the 20th-century average—the highest since records began in 1850. In this warming world, the transportation sector presents a daunting challenge; its carbon dioxide emissions have nearly tripled since 1970, now reaching almost 8 gigatonnes annually. We no longer have the luxury of merely reducing our footprint; we must eliminate it.
Enter liquid hydrogen (LH2). Imagine a future of silent, soot-free skies and shipping lanes where the only exhaust is a crystalline mist of water. LH2 is not a fringe experiment or an unproven fuel of the future. It is a seasoned, space-proven technology entering its second act. This cryogenic liquid is uniquely poised to decarbonize the heavy-lifters of our global economy—from long-haul trucking to transcontinental aviation—transforming how we move goods and ourselves across the globe.

2. It’s Not New Technology—It’s Space-Age Heritage

While many view hydrogen as an emerging tech, it actually carries a deep space-age pedigree. Liquid hydrogen has been in continuous large-scale use for over six decades. The timeline is remarkable: from the first gas turbines in the 1930s to the 1950s flight demonstrations of the Martin B-57 Canberra, and finally becoming the lifeblood of the 1960s Apollo program.
NASA’s experience with the Centaur upper stage and the Saturn rocket stages wasn't just about reaching the moon; it was about mastering the most energy-dense fuel in the universe. Today, we aren't testing the basic physics of LH2—we are simply optimizing the systems for terrestrial costs. This heritage provides a unique safety and infrastructure foundation that other green technologies simply do not have.
"Since LH2 has been continuously used in the space sector for nearly six decades, all the necessary systems and supply chains for large-scale LH2 production, delivery, storage, fueling, and launch vehicle consumption are well established."*

3. The End of the Legacy Fuel Model

The transition to LH2 signals the end of the legacy fuel model. For a century, we have relied on a rigid chain where fuel is extracted in one corner of the world, refined in another, and shipped to a third for use. LH2 enables a decentralized energy node concept.
Because hydrogen can be produced via water electrolysis using renewable microgrids and modular liquefiers, fuel can be generated on-demand at the point of use, such as an airport or a remote trucking hub. We are even seeing the prospect of geologic hydrogen—naturally occurring hydrogen created by subterranean catalytic reactions in iron deposits.

4. The Weight vs. Volume Tug-of-War

Liquid hydrogen presents a counter-intuitive physical profile that makes it the "holy grail" for heavy-duty mobility. By mass (gravimetric density), LH2 packs nearly three times the energy of fossil fuels. However, by volume, it holds less than 25% of the energy content of gasoline.
In the world of logistics, mass equals revenue. For a long-haul truck or a cargo plane, every kilogram of battery weight is a kilogram of lost payload. Because LH2 is so light, it allows these vehicles to maintain high payload capacities and long ranges that battery-electric systems cannot match. While the low volumetric density means tanks must be larger, the trade-off favors the heavy-lifters: planes can fly further and trucks can carry more goods, making the physics of LH2 a direct driver of economic viability.

5. The "Thermos Tank" Revolution

Storing a liquid at -253°C (-423°F) requires high performance insulation. Traditional metal tanks aren't enough; vacuum-jacketed (double-wall) dewar construction is required for most applications. This functions as a super-insulator, utilizing advanced materials like mulitlayer insulation (MLI), aerogels, perlite, or other suitable insulation options within an evacuated space to reduce heat transfer.
To make LH2 viable for the long haul, we distinguish between two critical thermal management strategies:
  • Passive Methods (e.g., conduction-optimized structures and MLI to reflect radiant heat).
  • Active Methods: (e.g., cryocoolers and cryo-refrigeration to maintain the liquid state indefinitely).
Perfecting these strategies is the key to minimizing boil-off—the costly loss of fuel as it warms.

6. Safety is a Matter of Physics, Not Perception

Public perception of hydrogen is often anchored in myth, but the physics of the molecule tell a different story. Unlike gasoline, which pools on the ground and creates a lingering fire hazard, gaseous hydrogen has a 20 m/s rise rate. If a leak occurs, the fuel dissipates almost instantly into the upper atmosphere.
Hydrogen also has an auto-ignition temperature of 585°C—higher than natural gas. When it does burn, it produces no smoke or soot, eliminating the inhalation risks common in hydrocarbon fires. While the flame is invisible in daylight and requires infrared sensors for detection, its low radiant energy means it is less likely to cause heat damage to surrounding structures than a petrol fire.
"Education and awareness of safe hydrogen usage over time is needed to achieve public and market acceptance."*

7. The Decade of Deployment

We are standing at the threshold of a tiered deployment. In the near-term (0–5 years), we will see LH2 increasingly used for buses, rail, and marine vessels. The medium-term (5–10 years) will bring commercial commuter aircraft and drones into the fold. Beyond 10 years, LH2 will integrate into the long-range aviation sector, supported by a global footprint of renewable energy hubs.
As we chase the "1-1-1" goal—$1 for 1 kg of clean hydrogen in one decade—we are leveraging machine learning and generative AI to optimize every step of the supply chain. The question is no longer if hydrogen will power our world, but how quickly we can scale. Are we ready to trade the convenience of the traditional gas pump for a fuel system that finally matches the scale of our climate challenge?

Nevertheless, it represents a noteworthy capability for several reasons that currently plague other AI options: hallucinations are mitigated by constraining the sources; the content can remain private to the user and not used for training; chatbot prompts can be used to explore the sources; and various "studio tools" can be applied.
The studio tools include auto-generated mind maps, podcasts, videos, articles (like the draft of this post), flashcards, quizzes, infographics, slide decks, and data tables. Up to 50 content sources can be contained in a single notebook with the free version enabling integrated exploration of a chosen topic. Paid versions allow hundreds of sources.
What to do with all these rapidly advancing AI tools? Misusing or overusing them is a problem both online and within organizations. But ignoring their utility or refusing to explore how they add value is a losing proposition. 
Personally, I plan to continue experimenting with how AI might help us accelerate the deployment of hydrogen systems. If that's of interest to you, visit the www.h2sage.com site and click on the request email updates button.]
