Verdagy, a pioneer in scaling electrolyzer applied sciences for industrial markets, demonstrated the business efficacy of its water electrolysis know-how, eDynamic, with two vital milestones on the trail to cost-effective inexperienced hydrogen at scale. 

In response to the local weather disaster, international locations everywhere in the world have set one among many aims to attain within the upcoming years: considerably scale back greenhouse gasoline (GHG) emissions on our planet. As a way to understand this goal, firms should decarbonize the manufacturing of a component like hydrogen, which is answerable for greater than 2% of complete world CO2 emissions—giving rise to inexperienced hydrogen.

Verdagy’s eDynamic course of used to acquire hydrogen—a common, mild, and extremely reactive fluid—is predicated on a chemical response often known as electrolysis, which makes use of {an electrical} present to separate hydrogen from oxygen in water. If the electrical energy required to set off this response is generated by way of renewable assets, inexperienced hydrogen then turns into possible, since no carbon dioxide will probably be emitted into the surroundings in the course of the power manufacturing course of. By changing the gray hydrogen produced utilizing fossil fuels everywhere in the world, 1 million tons of CO2 may very well be saved. 

To provide low-carbon, energy-carrying hydrogen molecules, electrolyzers separate the hydrogen and oxygen in water. Verdagy’s eDynamic methodology is meant to rapidly modify operational parameters as a way to combine effectively with renewables and seize the perfect enter power value. Verdagy has proven by way of fast scaling that it’s eDynamic methodology can resolve electrolysis difficulties for industrial functions. Beginning with its first lab cells, it progressed to pilot cells after which to the 1,000-hour run demonstration. It’s at present commissioning its 500-kW electrolyzer module. 

Verdagy’s water electrolysis know-how 

At present, there’s an growing curiosity in environmentally pleasant hydrogen-generation applied sciences. It’s because hydrogen’s potential functions are rising in a wide range of fields, together with energy technology, manufacturing processes within the metal and cement industries, gasoline cells for electrical automobiles, heavy transportation like delivery, manufacturing of inexperienced ammonia for fertilizers, cleansing merchandise, refrigeration, and grid stabilization. 

Among the many firms investing on this know-how is Verdagy, a spin-off of one other inexperienced chemical firm referred to as Chemetry. With headquarters in Moss Touchdown, Calif., Verdagy was based in Might 2021 with the intention of creating applied sciences for green-hydrogen manufacturing. 

The corporate is at present creating water electrolysis tech for the extraordinarily large-scale manufacturing of inexperienced hydrogen. By creating an entire new class of high-performance cells, electrolyzers, and vegetation, Verdagy’s options present the bottom manufacturing unit economics, in addition to the bottom upfront capital bills available on the market, the corporate stated. 

“We’re engaged on very large-scale, membrane-based cells, attaining excessive present densities on the electrochemical cell stage,” Verdagy CEO Marty Neese stated in an interview with EE Instances.

By utilizing bigger cells and working at greater present densities (greater than 10× of conventional alkaline water electrolysis), this know-how can produce extra hydrogen on the cell, stack, electrolyzer, and plant stage. 

Historically, electrolyzers are based mostly on one of many following two applied sciences: alkaline water electrolysis (AWE) and proton alternate membrane water electrolysis (PEM). As proven in Determine 1, Verdagy’s water electrolysis (VWE) combines the benefits of each AWE and PEM applied sciences, whereas eliminating their disadvantages. 

Verdagy’s “eDynamic” plant 

VWE know-how is predicated on a 20-MW electrolyzer and on a 200-MW plant (referred to as “eDynamic”), constructed utilizing very giant lively space cells able to working at industry-leading present densities. The “eDynamic” plant owes its identify to its potential to rapidly adapt operational parameters to seize the perfect enter power pricing. Which means it should use much less power when power prices are excessive and extra power when costs are low. This dynamic working vary, at present unmatched within the {industry}, mixed with very giant cells (see Determine 2) permits firms to drastically scale back capex. 

The “eDynamic” plant can be very environment friendly (the “e” stands for effectivity) and gives a really giant turndown ratio. 

“What we proved on the demo scale is that we may do a 20:1 turndown ratio, and there was peak energy pricing at some factors within the day,” Neese stated. 

“Like every other electrolyzer firm, we’d search to keep away from that price by turning down the plant as a lot as potential throughout excessive priced power regimes,” he added. “Correspondingly, although, as a result of now we have the aptitude to additionally flip up the plant, when power costs are inexpensive, we dynamically change the vary of the system and run at greater present densities and overproduce throughout these instances of day.” 

In consequence, Verdagy’s method avoids high-cost energy and capitalizes on low-cost energy with a extremely productive cell. 

“Every of our cells is three sq. meters and might produce over three kilograms of hydrogen per hour,” Neese stated. “Scaling up from there, you may determine that 1,000 cells would produce practically 80 tons of hydrogen a day. That begins turning into a really significant quantity on the 200MW scale.” 

“And since we’re utilizing very giant cells operating at excessive present density, the capex for that’s terribly low, which then opens the door to giga scale. After which when the economics are confirmed out, and we get the fee down, we’ll decarbonize utterly.” 

Potential markets 

After closing a $25 million funding spherical led by TDK Ventures to speed up the event of its large-scale electrolyzer know-how, Verdagy is selectively discovering companions and key verticals. Amongst its key traders, the corporate counts petrochemicals, industrial chemical substances, and mining firms. 

“These three markets are the place we’re seeing probably the most early business traction and curiosity, and they’re earliest alternatives for decarbonization,” Neese stated. “Then there’s a fourth alternative, which is expounded to the manufacturing of inexperienced ammonia.” 

In keeping with Verdagy’s hydrogen buy settlement mannequin, each gear and companies are supplied. The corporate begins with the gear after which selectively provides the aptitude to provide hydrogen as a service. That features one thing like a 10-year service wrap for all of the electrochemical cells, the electrodes, the catalysts, the coatings, and the membranes. 

“Predictive upkeep and operations will probably be included in a service package deal with the gear gross sales. Then, we’re additionally including challenge growth the place we’d do hydrogen as a person service,” Neese stated. 

All of the alternatives Verdagy presents can result in an built-in worth chain connecting all the way in which to one thing like inexperienced ammonia, in accordance with the corporate. At present, we’re witnessing totally different renewable power suppliers eager to get into electrolysis, and in some instances, they go additional downstream into inexperienced ammonia—they usually’re connecting these ecosystems. 

“We’re working very carefully with all method of builders, and one among our traders is a renewable power developer,” stated Neese stated. “We’re simply making an attempt to remain nimble sufficient to work with the upstream renewable suppliers after which provide them options that unlock no matter worth they wish to couple with downstream.”
