Dude, Where’s My Hydrogen-Powered Car?

With zero-carbon emissions, hydrogen was supposed to be an energy cure-all. So why aren’t we filling up our cars with it?

If this were a party, and you sat down and asked, “Why not hydrogen-powered cars?” you could be in for a long night. May I get you an espresso?

I get this question a lot. People wonder, given the current limits of battery technology, whether a hydrogen-powered car, using a fuel cell device to convert compressed hydrogen into electricity, would have longer range and quicker refill/recharge times.

Yes, if first you have the hydrogen. Preferably liquid hydrogen.

People assume hydrogen is abundant. It isn’t—not in a readily usable form. Atomic hydrogen bonds tightly to whatever is around. In the case of hydrocarbons, hydrogen has a death grip on compounds of carbon; in the case of water, it doesn’t want to quit oxygen.

Hydrogen is liberated from water in a process called electrolysis, using electricity to break its bond with oxygen. To separate H2 from fossil fuels—typically, natural gas, or methane—the process is called steam reforming. Neither is particularly efficient. Electrolysis can reach an energy efficiency up to 80% using best practices. That means it takes 50-55 kWh of energy—and associated emissions—to liberate 40 kWhs worth of “zero-emission” hydrogen.

Steam-methane reforming is about as efficient but the process produces intense carbon emissions, several times the hydrogen extracted, depending on the feedstock. It also requires a non-trivial sum of energy to compress H2 into a storage device—a hydrogen tank—so it might be used in an automobile.

Once on board, hydrogen’s ROI takes another hit at the fuel cell, a stack of permeable membranes where hydrogen is married with oxygen to produce water and electricity. The most efficient such devices yield about 60% of the potential energy, which knocks the system’s well-to-wheel efficiency down to 30-40%, comparable to that of a typical internal-combustion vehicle.

All of which is to suggest why, if your national energy policy aim is lower carbon emissions per unit of economic activity, hydrogen-based transportation has a hard time scaling.

How’s that coffee? Ready for another?

But even if zero-carbon hydrogen flowed like honey from the rock, it would be difficult to transport and deliver to millions of automobiles on a retail basis. Take pipelines: The infrastructure the oil-and-gas sector uses to move natural gas (methane) cannot readily be shared with compressed hydrogen.

Or fueling stations: The costs of the few publicly accessible H2 fueling stations that have been built in the last decade (there are currently 48 public H2 stations in the U.S., 47 in California and one in Hawaii) have been many times higher than those associated with conventional gas stations. These costs typically include a natural-gas reformer on site, avoiding the necessity of aforementioned pipelines and high capacity tanks. They also reflect the costs of compliance with federal, state and local regulations having to do with letting granddad pump his own high-pressure space fuel. Somebody at the city council meeting yells Hindenburg in three, two, one…

Hydrogen does have some lovely physical properties. Chief among them is high energy density by mass. A kilo of hydrogen embodies about three times the energy content (120MJ/kg) as a kilo of gasoline (44 MJ/kg, equivalent to six properly fused Molotov cocktails).

On that account, hydrogen mops the floor with the best lithium batteries. Tesla’s new 4680 cells may pencil out to, at best, 300 Wh/kg. The most energy-dense solid-state batteries on the horizon might deliver two to three times more. It still sums to less than 1kWh per kilogram, a fraction of hydrogen’s energy-carrying capacity.

And yet, outside of a few small-scale projects and compliance cars such as the Toyota Mirai, the entire automotive world is turning to batteries. Why?

In light vehicles, hydrogen’s limiting factor has always been its low energy density by volume—the size of the bottles, in other words. A typical automotive-grade pressure vessel might be a cylinder three feet long and one foot in diameter, nominally (3:1 ratio), heavily overwrapped with carbon-fiber reinforcement and pressurized to 350-700 bar. Such a bottle holds a precious 5.6 kg of H2, worth about 185 kWh.

However, again taking into account the losses at the fuel cell, the effective capacity is more like 111 kWh, comparable to current and conventional lithium battery technology. In this way hydrogen has a range problem too.

The thing is, if you need to move energy in bulk, or just move bulk, H2 is your friend. Test fleets of fuel-cell-powered heavy trucks are already on the road, as well as locomotives, ships, buses, and other applications where dimensional space isn’t quite so dear as in light vehicles.

Hydrogen could play a role in EV-charging infrastructure, especially in remote or delicate areas where wise policy would avoid generators, power lines and substations. Imagine an H2/EV station set up outside a national park, quietly producing electricity with a stationary fuel cell, using truck-delivered H2. “Compressed hydrogen is really a way to truck electricity around,” said David Reichmuth, senior engineer with the Union of Concerned Scientists.

Or you know what would be really cool? Liquid hydrogen (LH2), stored at -253 C. One cubic meter of cryogenic hydrogen represents about 2,343 kWh worth of energy, roughly equivalent to the stored energy of 23 fully charged Teslas.

And yet I know of only one effort to exploit cryo-hydrogen’s potential on four wheels: the Glickenhaus HFC Pickup. The work of Scuderia Cameron Glickenhaus (SCG) in Sleepy Hollow, N.Y., the HFC Pickup will be battle-tested in a future Baja 1000 off-road race, possibly using swappable tanks of liquid hydrogen to refuel on course.

And you thought it was hard to keep the beer cool.

Art can transform more than just walls—it shapes mood, evokes memory, and elevates the everyday. Discover how thoughtfully curated interiors can become living expressions of personal meaning and refined luxury, from sculptural furniture to bespoke murals.

  1. Artful Abundance: The Sophisticated Joy of Artful Interiors

Imagine a hushed hospital corridor, its sterile walls awash in the glow of flickering fluorescent lights. In that unexpected moment, a solitary Monet painting emerged—a luminous tableau of delicate lilies dancing in quiet defiance.

As the clinical austerity yielded to the graceful presence of art, this single work transformed into a vessel of solace and hope amid overwhelming uncertainty.

That moment continues to resonate with me—a vivid reminder that art transcends mere aesthetics to become a profound catalyst for emotional healing and inspiration. It is this transformative experience that fuels my passion as a biophilic interior designer.

I create environments where every element, from bespoke murals to sculptural installations, harnesses art’s power to elevate the human spirit, spark creativity, and enrich lives. Let us journey together into the world of luxurious interiors that define modern elegance.

2. Art as Wellness: A Daily Ritual of Rejuvenation

At its core, art is a daily ritual that renews both mind and spirit. Scientific research consistently confirms that nature-inspired art reduces stress, lowers blood pressure, and kindles creativity.

The simple act of beholding a tranquil landscape or a subtle floral motif transforms your space into a private retreat, offering solace amidst a hectic world.

In my practice, I meticulously select artworks chosen not only for their aesthetic appeal but also for their potent, therapeutic benefits.

Each piece serves as daily inspiration—a quiet invitation to experience calm and well-being. For example, our Hilton project demonstrates how hospitality resorts integrate nature-inspired art not only for its visual impact but also as a medium of healing; here, a collaboration with a local artist produced a masterful installation that functions both as a statement piece and a source of well-being.

3. Bespoke Brilliance: Celebrating Your Unique Narrative

Luxury design is profoundly personal. Bespoke art transcends mass-produced décor by capturing your unique story—whether through a custom mural reminiscent of your favourite botanical garden or silk wallpapers that evoke the allure of exotic landscapes.

Each personalised creation turns your walls into a living narrative of cherished memories and distinctive taste. Consider how a thoughtfully designed space can reflect your individuality and elevate your living experience.

4. Sculptural Elegance: Redefining Spatial Dynamics

Art is not confined to two dimensions. Three-dimensional sculptural works bring vitality to interiors by adding depth, texture, and tactile allure.

Picture a gracefully sculpted piece—a marble table echoing the gentle rhythm of ocean waves or a repurposed bronze branch serving as an elegant room divider.

Such statement sculptures command attention while seamlessly integrating form with function and providing a natural conversation starter in any refined space.

5. Architectural Artistry: When Structure Meets Art

A truly sophisticated home elegantly merges art with architecture. Imagine a residence where bespoke staircases curve with elegance, where hand-carved wooden doors evoke the intricate beauty of nature, and where expansive windows frame breathtaking vistas.

In these spaces, every architectural detail contributes to a cohesive canvas of artistic expression. As you envision your own home, consider how your surroundings can be thoughtfully designed to reflect both beauty and purpose.

6. Furniture as Functional Art: Merging Practicality with Mastery

In luxury interiors, even the functional becomes exceptional through artful design. Consider a one-of-a-kind, hand-carved pink marble swivel chair—a masterpiece where practicality meets refined craftsmanship.

More than just a piece of furniture, this chair sparks conversation and serves as an emblem of creative innovation and exclusivity.

Let this be a symbol of how every element in your home might reflect your dedication to exquisite artistry.

7. Digital Sophistication: The Future of Artistic Expression

In an age defined by rapid technological advancement, digital art installations offer a contemporary twist on traditional forms.

High-resolution displays now present dynamic landscapes—a cascade of waterfalls, the quiet majesty of a forest, or a serene digital ocean vista—that adapt and evolve with your environment.

This modern element seamlessly aligns cutting-edge technology with timeless aesthetics, ensuring your space remains as innovative as it is elegant.

8. Luxurious Textiles and Furnishings: The Essence of Understated Elegance

Luxury is often revealed in the details: the textures, colours, and fabrics that together create a haven of understated splendour.

Bespoke silk cushions with intricate botanical embroidery, sumptuous velvet throws that evoke tropical charm, and bedding that mirrors the ethereal beauty of cloudscapes all contribute to an atmosphere of refined elegance and comfort.

Every tactile detail is chosen to evoke warmth and stand as a testament to your taste for excellence.

9. Refined Heritage: Honouring Timeless Craftsmanship

In the realm of luxury, tradition and modernity exist in perfect harmony. Integrating timeless antiques—such as a rare Vladimir Kagan couch or a coveted Hans Wegner chair—with contemporary design creates a dialogue that honours both heritage and innovation.

These storied pieces carry with them a legacy of masterful craftsmanship, adding layers of significance and depth to your living environment. They remind us that true elegance is built upon a foundation of enduring quality.

10. The Art of Personal Meaning: Crafting Your Legacy

Ultimately, art is the language through which you express your unique legacy.

Every carefully chosen piece reflects a part of your personal journey, turning your living space into a narrative as emotionally resonant as it is visually stunning.

It imbues your environment with memories, aspirations, and the essence of who you are—a living masterpiece that evolves with time.

Reflect on how these elements might not only beautify your home but also stand as timeless expressions of your personal story.

Now is the moment to immerse yourself fully in the joy of art. Elevate your surroundings and transform your residence into your greatest masterpiece.

Your heart, your legacy, and your space deserve nothing less than extraordinary artistry.
