Raffi Garabedian spent a dozen years growing sun panel generation at First Sun, a photovoltaics corporate that lately has a marketplace price round $8 billion. The technologist then went directly to co-found a blank hydrogen start-up Electrical Hydrogen, which he is lately construction out as its CEO.
Garabedian’s occupation trail might appear sudden. Whilst solar energy is sort of universally authorized as a blank calories supply, hydrogen manufacturing is steadily perceived as a shady nook of the local weather area the place oil and fuel firms are the use of smoke and mirrors to invent a explanation why to stay their very own infrastructure related.
However Garabedian is aware of all that. He additionally is aware of that now not all hydrogen is created in the similar method. And hydrogen is basically crucial to existence on earth and has super doable to be a linchpin in vital trade sectors that may another way be onerous to decarbonize.
A decade in the past, the sun trade used to be “an hands race” to broaden the most affordable and best possible photovoltaics generation, he advised CNBC. “Technologists like me, we have been within the scorching seat, which is what excites me,” he mentioned. Now, the sun trade is in execution mode as a substitute of quick-innovation mode.
So he requested himself, “What is the subsequent factor that must be performed? What is the largest affect factor in decarbonization and local weather tech that should occur? That is the idea procedure that led me to hydrogen.”
The promise and issues of hydrogen
Hydrogen is already crucial in chemical business processes, together with refining crude oil into helpful petroleum merchandise, and for making ammonia-based fertilizer in the course of the Haber-Bosch procedure, which has helped the sector feed itself thru huge inhabitants enlargement during the last century.
“With out it, tens of millions of folks die,” Garabedian mentioned.
Some purists argue that hydrogen must handiest be produced and utilized in chemical processes and to make ammonia, however Garabedian rejects that view.
First, he argues, hydrogen gasoline may just scale back emissions in some sectors of the economic system that might be very onerous to decarbonize with electrical energy, like airplanes and massive boats.
For planes, the load of the calories supply is important and hydrogen is each energy-rich and really gentle — and generates minimum emissions when burned, not like jet gasoline. For long-haul delivery, freight liners want as a way to trip a very long time and a some distance distance with out refueling. Ammonia created from blank hydrogen and compressed hydrogen are each contenders for delivery trade gasoline assets, and cleaner burning than the “bunker gasoline” maximum huge ships use nowadays.
Hydrogen may be a possible possibility for long-duration calories garage, which is necessary for scaling up sun and wind renewable calories.
Numerous individuals are excited by battery generation for calories garage, and in truth Garabedian sits at the board of ESS, a battery corporate having a look to broaden batteries for utilities to retailer calories for 4 to twelve hours. However for ultra-long length — 100 hours of garage or extra — herbal fuel is the commonest answer nowadays.
For ultra-long garage, hydrogen is much less effective than any other blank applied sciences, like batteries or pumped hydro, however the quantity of calories (capability) you’ll retailer is way larger, in step with the Power Garage Affiliation.
With the correct generation and infrastructure, sun and wind energy might be used to generate hydrogen, which might then be saved and burned later when the solar is not shining or the wind is not blowing. It will also be shipped all over the world to the place calories assets are maximum wanted — hydrogen may also be transformed right into a liquid at a perfect chilly temperature and saved and moved on in cryogenic tanks on particular ships, very similar to how liquified herbal fuel strikes lately.
The ability of electrolysis
However there is one giant caveat to the usage of hydrogen to make the calories sector cleaner.
The most affordable techniques to make hydrogen nowadays use herbal fuel. The method produces carbon dioxide, which contributes to local weather alternate. Additionally, amassing and distributing herbal fuel inevitably leads to methane emissions from fugitive leaks — and methane is an much more potent and perilous greenhouse fuel than carbon dioxide.
This so-called “gray” hydrogen and its cousin, “blue” hydrogen, which is produced in the similar method however with an try to seize and sequester the carbon dioxide emissions, are non-starters for Garabedian.
“Basically, I feel maximum firms in oil and fuel see blue hydrogen with the intention to perpetuate their trade fashion,” he mentioned. He does not suppose they may be able to extend it perpetually.
“The tip of herbal fuel is across the nook,” he mentioned. “And having been thru over a decade in sun, I’ve this feeling that those transitions can occur so much quicker than the entrenched trade desires to consider they may be able to occur.”
The solution, Garabedian believes, is to discover a cost-effective approach to generate generate hydrogen with out the byproducts that heat the local weather.
One blank approach to generate hydrogen is by way of the use of blank calories assets like sun and wind to energy electrolysis — splitting water, H2O, into hydrogen and oxygen.

Electrolysis is pricey nowadays, however Electrical Hydrogen targets to mend this by way of construction “very dense” electrolyzers to run within gigantic and super-efficient vegetation that may generate up to 100 megawatts of energy, the place standard vegetation perform at about 5 megawatts.
“The type of plumbing right here isn’t reasonable – suppose high-pressure stainless-steel like you may see in a chemical plant,” Garadedian advised CNBC. Electrical Hydrogen’s way is supposed to scale back the price of every plant by way of minimizing plumbing and different infrastructural prices.
That is the concept, anyway — Garabedian would not percentage main points of the chemical generation concerned for worry of giving freely business secrets and techniques.
“Economics is what wins. It is not that folks do not wish to do the correct factor. However it is also now not that folks wish to do the correct factor. Companies make financial choices.”

CEO and Co-Founder, Electrical Hydrogen
You have to observe that that is all at an excessively early level, and the corporate has no income or shoppers nowadays.
The corporate is solely over two years outdated. In 2019, David Eaglesham, the preliminary CTO at First Sun, used to be an entrepreneur-in-residence at Invoice Gates’ local weather funding fund, Step forward Power Ventures, the place he used to be learning find out how to produce hydrogen cost effectively. Eaglesham discovered Garabedian used to be fascinated by operating on a brand new generation and the 2 made up our minds to paintings in combination to construct a hydrogen corporate in line with some concepts Eaglesham had in his residency. Two different key gamers at the group are Derek Warnick, who has spent the decade and a part operating in blank calories finance, and Dorian West, who has 25 years’ engineering revel in, together with at 15 at Tesla.
The corporate formally included in December 2019, and self-funded till March 2021, when Electrical Hydrogen first raised cash. In June, the corporate introduced $24 million led by way of Step forward Power Ventures.
Base line: It is all about charge
Garabedian is aware of that good fortune will handiest come if his answer lowers the price of calories.
“The important thing level is worth. Those are commodities. We are not promoting Teslas, which you purchase now not simply because they are blank, you additionally purchase them as a result of [they’re] actually amusing to force,” Garabedian mentioned.
The most affordable hydrogen nowadays is gray hydrogen created from herbal fuel down close to Henry Hub, Louisiana, the place it prices round $1.50 consistent with kilo, in step with Garabedian.
“That is our goal. Our goal is to show renewable calories into $1.50-a-kilo-or-less hydrogen, thereby making it a cheap choice to the grimy gray supply,” mentioned Garabedian.
If blue hydrogen turns into the trade usual, then the baseline worth is prone to transfer to between $2 and $2.25 consistent with kilo, which “makes it a lot more uncomplicated for me to go into the marketplace,” he mentioned.
Garabedian discovered the onerous lesson about economics in his decade within the sun trade.
A dozen years in the past, the sun trade used to be supported with subsidies and regulatory mandates, and about 2015, solar power reached “grid parity,” which means it prices the similar because the wholesale worth for electrical energy generated at the grid.
The ones incremental financial choices made trade by way of trade, daily, will transfer the calories transition, in step with Garabedian.
“Economics is what wins. It is not that folks do not wish to do the correct factor. However it is also now not that folks wish to do the correct factor. Companies make financial choices.”
