“Hypergrowth” and “renewables” are two words that rarely go together. The infrastructure that is required tends to prevent the rapid growth that we see in cloud or advertising stocks. Most renewables either show the signs of a cyclical industry or they show signs of “growth at any cost.” Plug Power is a growth at any cost company. This has worked many times in tech – to do whatever it takes keep growing – so we won’t want to discount the company based on this tactic. What Plug Power and other renewables require is a different mindset than cloud, ad-tech, consumer tech or crypto investing.
We’ve discussed before that the cost for clean energy is finally competitive with the cost for fossil fuels. This has helped drive the investments in building more infrastructure. However, this isn’t the case for clean hydrogen which complicates Plug’s story. We discuss this more below and why we are interested in Plug despite hydrogen being far behind solar and wind in terms of cost reduction.
Please note: at this time, the I/O Fund has chosen Stem and Plug Power as our two choices for exposure to renewables. This was discussed in the July 2021 Renewables Overview.July 2021 Renewables Overview.
Overview of Hydrogen:
The Paris Agreement of 2016 is widely considered to be the point when global initiatives in renewable energy were kickstarted. The proclamation was signed by 196 countries that promised to limit global warming to “below 2-degree Celsius above pre-industrial levels.” This translates to a goal of cutting carbon emissions by 25% by 2030 and to be net zero by 2070.
When we’ve covered renewables in the past, the main takeaway is that the cost to produce energy is dropping to where it’s competitive with fossil fuels. This lower cost to produce solar PV and wind has resulted in more interest in electrolytic hydrogen. The ultimate goal is to use clean energy to produce hydrogen rather than natural gas or coal. This will be accomplished by building electrolyzers near solar fields and wind farms to supply the hydrogen and then transport it where it’s needed. Hydrogen is transported either by pipeline or by liquid form on ships. From there, it’s used to fuel a wide variety of vehicles and buildings.

Most importantly, hydrogen is designed for energy storage whereas wind and solar are designed for energy generation, therefore, a hybrid of the two is ideal. Hydrogen allows energy to be stored for weeks — and even up to months — after solar or wind has generated energy. This is important because wind and solar fields are often located too far away from cities to be effective without a storage option
Of all the technologies in existence today, hydrogen has the greatest potential for seasonal energy storage, according to the National Renewable Energy Laboratory (NREL). The major components to hydrogen power is fuel cells, refueling equipment and electrolyzers. Fuel cells use the fuel from hydrogen with the oxidizing effects of oxygen to create electricity. They are made up of an anode, electrolyte of ions and cathode.

Today, the grid is mainly used to produce hydrogen. Currently, natural gas is the primary source of hydrogen production and accounts for 75% of the hydrogen production in the world today, or about 70 million tons. This equates to 6% of the global natural gas use. After natural gas, the second most popular supply source for hydrogen is coal. Grid-based hydrogen is used in oil refining, ammonia production, methanol production and steel production. This is distinct from clean hydrogen.
Here are the various ways to produce hydrogen:
- Renewables: using solar and wind, hydrogen can be produced with water (electrolysis) – considered clean hydrogen (or green hydrogen)
- Nuclear: same as renewables, nuclear energy can be used for electrolysis
- Steam methane with CCS: proven method with carbon capture, utilization and storage with natural gas, needs to scale – considered blue hydrogen
- Steam methane: uses natural gas without carbon capture, utilization and storage, thereby producing carbon emissions. This is the current way hydrogen is produced and produces many emissions as it’s not clean hydrogen production rather it’s gas and coal powered hydrogen – considered gray or brown hydrogen
Fuel costs account for 45% to 75% of production costs. This makes hydrogen fuel cells sensitive to gas prices (for the natural gas production) and this is why it costs more to produce hydrogen in regions like Japan, China and Korea, where natural gas is an import.
To put in perspective how far behind hydrogen development is (and, consequently profitability), consider that in terms of megawatts, hydrogen in 2017 was comparable to solar in 1996 and wind in 1992.

Bull Case for Hydrogen:
The bull case is that hydrogen can be useful in many industries where is has little to no presence, such as transport, manufacturing, buildings and for power generation. This will be catalyzed by the need for energy storage as it will be impossible to power the world’s energy needs with renewable energy sources on their own. Essentially, the argument here is that world cannot meet its renewable energy goals without energy storage and hydrogen is the best candidate for this.
The decarbonization goals set forth by the Paris Agreement and the decarbonization that commercial industries are seeking on their own (Amazon, Wal-mart, etc) will require a versatile energy carrier. Therefore, a primary bull case is that the decarbonization goals will require hydrogen for energy storage as they simply can’t be met with renewable energy sources alone. The expectation is that governments will be forced to drive down the cost of hydrogen to meet these goals. The driving down of costs for solar and wind with subsidies is cited as an example of how this has been successfully accomplished. For instance, New York has committed $13 million in state tax credits to Plug Power for building its Gigafactory in the Rochester area.
On a similar note, costs to produce hydrogen have halved in the last five years and are at 3% of their 2005 level currently. Another point for the bull case is that hydrogen can use the existing natural gas pipelines and network. Transporting hydrogen through existing pipelines is a lower cost option for delivering larger volumes.
The hybrid method of using hydrogen as an energy converter alongside renewables energy production can save hundreds of billions in Euros, according to a study done on the European Union. In the EU, the goal is to have 32% of the energy demand and 50% of the electricity demand come from renewables by 2070.
Bear Case for Hydrogen:
The bear case is that hydrogen production is cost prohibitive as there is an efficiency loss of up to 70% when converting energy to another form, such as from electricity to hydrogen that is then shipped, stored, and then converted back to a fuel cell. In this scenario, the 70% efficiency loss means hydrogen is more expensive than the electricity or gas used to produce it.
According to the Wall Street Journal and BloombergNEF, hydrogen supplies less than 5% of the world’s energy and could reach nearly a quarter of global energy consumption by 2050 for a total of $2.5 trillion in direct revenue annually.
Admittedly, 2050 seems a ways off with current CAGR at 4.32% through 2027. The global generation market was at $117 billion in 2019 and is estimated to reach $165 billion by 2027. Another source puts the near-term projection at 5.7% CAGR from 2021 to 2028. Steam methane will continue to have the largest share through the forecast period.
This low CAGR and far-off projections add to the bear case around the efficiency loss for hydrogen, which is why we placed the CAGR growth under the cons. Typically, this low CAGR would mean the market is not investable (at least not for growth investors like ourselves).
However, as the bulls point out, this can change quickly if there is enough pressure from legislation and corporate interest.
Plug Power:
Plug Power manufactures fuel cell systems for the industrial sector and manufacturing sector. The company’s line of products include GenKey, GenDrive, GenFuel, GenCare and ProGen. GenKey helps material handling vehicles reduce dependency on lead-acid or lithium-ion batteries. GenDrive offers a proton exchange membrane fuel cell to power material handling vehicles, such as forklifts and hand operated trucks. GenFuel provides a hydrogen fueling system for GenDrive vehicles. ReliOn provides backup power for telecommunications and the utility sector. ProGen offers fuel cell engines for the electric vehicle market to replace batteries. Here’s a good article about ProGen and the partnership with Renault.
By the end of 2022, Plug Power will have two of three plants operational in Georgia, Pennsylvania and New York. The plants will be green hydrogen plants using electrolyzers for hydrogen produced by wind, solar and hydropower. These plants will help Plug achieve the company’s goals of producing 500 tons per day of green hydrogen by 2025 and 1,000 tons by 2028.
- New York’s Gigafactory will be where the largest green hydrogen product facility plant will be built in North America. The initial production will be 45 metric tons of green liquid hydrogen to service the NE regions with 120 megawatts of eletrolyzers producing hydrogen.
- In Southern Central Pennyslvania, Plug will be leveraging Brookfield Renewables hydroelectric facility to potentially produce 15 tons per day.
- Last month, Plug announced plans to build a plant in Georgia with plans to produce 15 tons per day. This plant will be near Home Depot and Southern Company’s headquarters.
This quarter, the company discussed expanding its product line from material handling to expanding more into mobility. This includes various vehicles, such as commercial fleets, airport ground equipment and tuggers for factories. General Motors (GM) was named as the “fourth pedestal” customer for its auto manufacturing facilities. This includes factory tuggers and forklifts. These factory vehicles are loading and unloading heavy equipment everyday which typically requires battery power. The other three pedestal customers for Plug are Amazon, Walmart and Home Depot. We touch more on this below.
The company also released a new product last year called GenSure HP that provides backup power for data centers and energy storage systems with potential deployment in 2021. The backup power solutions compete with generators and backup battery power.
Plug Power acquired United Hydrogen Group and Giner ELX, a leading provider of hydrogen engines and fueling solutions. This acquisition lends itself to Plug Power producing more green hydrogen. At the time of acquisition, United Hydrogen Group was producing 6.4 tons of hydrogen with expertise in hydrogen generation, liquefaction and distribution.
Giner ELX specializes in PEM electrolysis including grid-level storage solutions and also fuel cell vehicle refueling stations. The company uses electrolyzers to turn surplus power into hydrogen. The result is injecting hydrogen into the natural gas network or fueling turbines for peak-time electricity generation. The long-term goal is to have hydrogen fueling stations that look like gas stations.

Partnerships:
Most stock analysts will point towards the partnerships that Plug Power has as either a major benefit or as a customer concentration risk. Both are probably true.
Amazon is Plug’s biggest customer for both fuel cells and electrolyzers. The partnership formed in 2017 when Amazon agreed to a $600 million deal to equip forklifts in Amazon’s warehouses. The incentive to use fuel cells over batteries is partly driven by reducing labor and freeing up physical space. In exchange, Amazon had the right to buy up to 23% of the company through warrants. The warrants vested last year and Amazon took control of 55 million shares at a price of $6. The warrants caused Plug Power to report negative revenue last year with the loss from the warrants being greater than the company’s sales. The more headline-worthy development as of late is that Amazon sold its shares and this can appear like a lack of confidence from one of Plug’s partners. On the other hand, Amazon may have wanted to cash in on the gains as Plug has been trading around $25.
In 2010, Wal-Mart partnered with Plug for the first time, and in 2017, the partnership was expanded with a three-year contract and an opportunity for Wal-Mart to buy 17% of Plug Power. At the time, Wal-Mart made up 34 percent of Plug’s revenue. Plug supplies Wal-Mart with GenDrive fuel cell-powered vehicles in 37 distribution centers. In August of 2020, Plug Power expanded again with Wal-mart to supply their eCommerce network.
Similar to Wal-Mart and Amazon, Home Depot is a partner with Plug Power on reducing electricity and battery use by using fuel cell-powered material handling fleets. Most recently, the two companies partnered on a Dallas, Texas facility that is 1.5 million square feet with Plug powering the material handling fleets.
In the Q1 2021 recap, Plug Power also discussed its partnership with General Motors, what the company calls its “fourth pedestal customer” with GM deploying GenKey solutions at multiple plants.
With the Renault partnership, Plug Power will be putting its fuel cells into light commercial trucks in Europe. Road tests will start by early 2022 with a goal of 20,000 trucks on the road by 2025. The two companies have a goal of reaching 1/3 of the market in 2030, when an anticipated 500,000 vehicles will be hydrogen powered. That would represent 7X growth between 2025 and 2030.
Financials:
As the title of this analysis states, Plug Power is a hypergrowth company in renewables. This hypergrowth is priced at a premium with Plug trading at up to a 75 forward P/S. When you adjust Plug Power for a 1-year forward to account for its forward growth compared to renewables peers, it becomes more reasonable. Pictured below, Plug narrows the gap with Enphase from a difference of 14 to a difference of 7 on the 1-year forward.

For the first quarter of 2021, Plug Power reported $72 million in revenue, up 76% year-over-year from $40.8 million. Gross billings were up 71% year-over-year at $73.7 million, compared to $43.0 million in the year-ago quarter. The revenue was a beat as analysts were expecting $69 million in sales but the EPS missed.
The gross product margin was at 38% although the company reported gross losses of ($12 million). Operating losses were at ($48.2 million) with net losses of ($60.8 million). This works out to EPS of ($0.12) with analysts expecting ($0.08). These gross margins are an improvement on a percentage basis from the ($9.7 million) lost in the year-ago quarter on ($40.9 million) in revenue.
The company has raised cash by selling stock for $1.6 billion and also for $1.8 billion. This resulted in $4.4 billion in cash for the company with $330 million in debt despite diluting shareholders. The company has a term loan with a 9% interest rate.
These losses are incurred due to the costs associated with fuel cell systems and related infrastructure, plus the cost to deliver fuel to customers. Growth investors need to understand there is an inherent cost to the renewables sector and get comfortable with losses before a company reaches scale. As discussed in the Hydrogen Overview above, Plug Power is exposed to commodities such as natural gas prices and also natural gas supply.
In regards to this quarter, Plug Power highlighted a few events that negatively impacted their operating margins. Fuel gross margins were negatively impacted due to the escalation of rates from one of their natural gas suppliers and from force-majeure events that caused the price of hydrogen to spike. One of those was the Texas freeze. The company is also exposed to freight costs, which caused a $2 million expense. The company stated in the Investors Letter that they plan to diversify their supply chain to mitigate this moving forward.
The company reaffirmed its targets for 2021 and also for 2024. The company’s goal for 2024 is $1.1 billion in revenue from 50% green hydrogen. The company stated the following regarding 2021 guidance: “Investors should expect $115 million to $120 million of gross billings for the quarter. This is approximately 40% of our target revenue of $475 million for the year. Usually, at this point in the second quarter, we are about 33% of our annual revenue will have been achieved. We are at a run-rate that is higher from both a revenue and growth rate level than we have experienced in the past. We also foresee a very strong third quarter.”
If Plug Power hits the revenue target for 2021 at $480 million and then the gross billings target of $1.2 billion and the revenue target of $1.1 billion in 2024, then that would be 150% growth. This is substantial for a renewables company that faces cost efficiency issues inherent to its industry.
Accounting Issues:
On March 15th, Plug Power announced the company would need to restate three years’ worth of financial statements. At the time, the company stated the restatement would not affect the company’s cash position, business operation or the return from commercial agreements.
The changes were: 2020 net revenue was $7.2 million compared to the previously stated net loss of $100 million and the net revenue of $230 million was an adjusted revenue loss of $300,000. This came after a large EPS miss in the fourth quarter of ($1.12) compared to ($0.11) expected. As previously discussed, the revenue was also negative because of Amazon exercising its warrants which led to a revenue miss in the fourth quarter of $32 million in losses compared to roughly $50 million expected.
The restatements pertained to the accounting for service contracts and classification of certain costs, such as R&D. The overall impact was minimal with a total decrease in EPS of ($0.13) or about a 6% increase in the company’s total loss. The change in reported sales amounted to a 2% decline. There was no change in cash.
Risks:
We’ve reviewed the risks in this analysis. Mainly the concentration of customers and also the cost efficiency of hydrogen as it costs more than the gas to produce it. Competitors are another risk as they range from smaller in size, such as Ballard and FuelCell Energy, to gas companies, like Shell and BP Amoco.
Conclusion:
We understand the challenges around hydrogen yet are willing to take the risk as any progress will be aptly rewarded. Perhaps it will be to our benefit the company’s stock was beaten down over a minor accounting error. We like Plug’s Power ability to post hypergrowth despite the challenges with hydrogen and especially clean hydrogen. We think incremental improvements – whether that’s subsidies, new global partnerships, or a stronger move into mobility – could cause the company to become a renewables leader.
