Key Information

Business overview

[edit]

OnSite Generation

[edit]

The OnSite Generation business segment is based on water electrolysis technology, which involves the decomposition of water into oxygen (O2) and hydrogen gas (H
2) by passing an electric current through a liquid electrolyte.[4] The resultant hydrogen gas is then captured and used for industrial gas applications, hydrogen fueling applications, and is used to store renewable and surplus energy in the form of hydrogen gas.[4] Hydrogenics' HySTAT electrolyzer products can be used both indoors and outdoors.[4]

Power Systems

[edit]

The Power Systems business segment is based on PEM fuel cell technology, which transforms chemical energy resulting from the electrochemical reaction of hydrogen and oxygen into electrical energy. (Edgar) Its HyPM products can handle electrical power outputs ranging from 1 kilowatt to 1 megawatt.[4] The company also develops and delivers hydrogen generation products based on PEM water electrolysis.[4]

Power to Gas

[edit]
Main article: Power to gas

Power-to-Gas is an energy process and storage technology, which takes the excess power generated by wind turbines, solar power, or biomass power plants and converts carbon dioxide and water into methane using electrolysis, enabling it be stored.[5][6][7] The excess electricity can then be held in existing reserves, including power and natural gas grids.[6][7] This allows for seasonally adjusted storage of significant amounts of power and the provision of CO2-neutral fuels in the form of the resulting renewable energy source gas.[6][7]

History

[edit]

In 1988, Hydrogenics was founded under the name Traduction Militech Translation Inc.[8] In 1995, it entered into the fuel cell technology development business and Traduction Militech Translation changed its name to Hydrogenics in 1990.[8]

In 2002, Hydrogenics acquired EnKAT GmbH, which formed its Hydrogenics Europe division.[9] It also acquired Greenlight Power Technologies, Inc., a competing fuel cell testing business, in 2003.[9] A year later, in 2004, the company acquired Stuart Energy, a manufacturer of hydrogen-generation products based on alkaline electrolyte technology.[8][10]

In 2007, Hydrogenics narrowed the focus of its fuel cell activities by exiting the fuel cell testing business and working more on forklift power and backup power markets.[8] That same year, Heliocentris partnered with Hydrogenics and SMA Solar Technologie to incorporate Hydrogenics' fuel cell power modules into stationary backup power systems.[8]

In September 2010, Hydrogenics formed an alliance with CommScope Inc., a Hickory, North Carolina–based multinational telecommunications company.[11] Per the alliance, CommScope invested US$8.5 million in Hydrogenics as part of a joint product development program.[8][12]

Hydrogenics signed a Memorandum of Understanding (MoU) with Iwatani Corporation, a Japanese industrial energy company, in April 2012.[13] The companies began to collaborate on hydrogen solutions in the Japanese energy market, including utility-scale hydrogen energy storage, hydrogen generation and fuelling, fuel cell integration, and industrial hydrogen generation.[13] Later that month Hydrogenics and Enbridge Inc. entered into a joint venture to develop utility-scale energy storage beginning in Ontario.[12][14] Under the agreement, hydrogen produced during periods of excess renewable generation will be injected into Enbridge's existing natural gas pipeline network.[14] In June 2013, Hydrogenics announced that its Power-to-Gas facility was operational with the first direct injection of hydrogen into a gas pipeline.[15]

Hydrogenics entered into a joint venture with South Korea–based Kolon Water & Energy to provide power generation in that country in June 2014.[16]

In 2019 Hydrogenics was acquired in large parts by Cummins as part of their New Power division. Hydrogenics is now owned 81% by Cummins and 19% by Air Liquide. The name of the company has since been changed to Accelera.[1]

Projects

[edit]

In June 2000, General Motors and Hydrogenics released their codeveloped HydroGen1, a vehicle powered by a first generation proton exchange membrane fuel cell system.[8] The following year, in October, the two companies developed low-pollution technology to power cars and trucks.[17]

In December 2002, Natural Resources Canada (NRCan) selected Hydrogenics to develop a next-generation hybrid fuel cells bus; Hydrogenics integrated its vehicle-to-grid technology into a 12.5 meter New Flyer Inverno 40i transit bus.[8] Hydrogenics' FC Hybrid Tecnobus midibus was exhibited in Europe in 2005.[8]

In January 2010, Hydrogenics began development of a next-generation power system to be used for surface mobility applications on the moon for the Canadian Space Agency.[2] The system includes an electrolyzer that produces both hydrogen and oxygen using solar power, and a fuel cell system that can be used for mobility, auxiliary, and life support systems.[2] Heliocentris and FAUN Umwelttechnick collaborated with Hydrogenics to develop a hybrid waste disposal vehicle for BSR (Berliner Stadtreinigung) in August of that year.[8]

In July 2012, Hydrogenics joined a consortium with EU members to build the world's largest steady state hydrogen storage facility in the Puglia region of Italy.[18] The system is part of the R&D smart grid project "INGRID."[12][18]

In April 2013, Hydrogenics won a contract to supply a 1 megawatt hydrogen energy storage system to German utility E.ON in Hamburg.[19] The system will use electrolyzers based on Hydrogenics' proton exchange membrane (PEM) technology for hydrogen production and use excess power generated from regional renewable energy sources, primarily wind energy.[19] In November the first of E.ON's P2G facilities provided by Hydrogenics became operational.[15] The Falkenhagen facility uses wind-powered electrolysis equipment to transform water to hydrogen, which is then mixed with natural gas.[3][15]

In February 2014, Hydrogenics was awarded two projects with the United Kingdom government.[20] Hydrogenics will provide its technology to build hydrogen fuel stations throughout the UK.[12][20]

Hydrogenics was selected as a Preferred Respondent for a power-to-gas project in Ontario by the Independent Electricity System Operator.[21][22] (IESO), a corporation responsible for operating the electricity market and directing the operation of the bulk electrical system in the province of Ontario, Canada, in July 2014.

Technical Achievements and Innovations

Advancements in PEM Technology

Hydrogenics advanced (PEM) technology primarily through innovations in stack design, scalability, and operational efficiency for both electrolyzers and fuel cells. The company's HyLYZER PEM electrolyzers featured stacks engineered for high-purity (>99.999%) at elevated pressures up to 30 bar, enabling direct integration with downstream applications without additional compression. These systems demonstrated responsiveness to fluctuating inputs from renewable sources, with developments including a 1.5 MW PEM stack optimized for variable power from , incorporating controls to maintain efficiency under dynamic loads. By 2019, Hydrogenics had scaled deployments to 2.5 MW units (expandable to 5 MW), validating reliability in commercial setups and contributing to cost reductions through modular stack architectures. In PEM fuel cell stacks, Hydrogenics' HyPM modules introduced proprietary enhancements, including optimized flow field patterns and improved catalyst utilization, which boosted and overall system compactness. Third-generation HyPM designs achieved lighter weight, reduced noise, and lower costs via advanced (MEA) integration and low-pressure cathode air delivery, with modules delivering up to 10 kW in integration-ready formats. Collaborations, such as with Dow Chemical, focused on sealing innovations to enhance PEM durability and prevent degradation in high-power stacks. These improvements enabled HyPM HD series stacks to operate at -40°C startups and support applications like backup power and mobility, with power densities representing breakthroughs over prior PEM technologies. Overall, Hydrogenics' PEM advancements emphasized practical commercialization, with over two decades of iteration leading to higher (e.g., reduced consumption in electrolyzers) and MW-scale viability, forming the basis for subsequent evolutions in large-format systems.

Efficiency and Milestones

Hydrogenics advanced PEM electrolyzer through iterative stack design improvements, achieving DC power consumption as low as 40 kWh per kg of (equivalent to approximately 67% LHV ) in HyLYZER systems, with nominal operation at 48 kWh/kg. System-level consumption reached ≤51 kWh/kg, incorporating balance-of-plant components like rectifiers with >97% . These figures represented practical advancements over earlier PEM benchmarks, enabling lower operational costs in renewable-integrated applications, though real-world system efficiencies often aligned closer to 56.5 kWh/kg in MW-scale deployments due to auxiliaries. On the fuel cell side, Hydrogenics' PEM stacks in HyPM modules sustained efficiencies around 50% LHV, supporting applications like backup power and mobility, with system-level verified in reversible operations. Incremental gains focused on rather than dramatic jumps, prioritizing under variable loads. Scalability milestones included the 2015 factory of the world's most powerful and power-dense PEM electrolyzer at the time, paving the way for commercial MW-scale units. By 2018–2020, Hydrogenics deployed 2.5 MW single stacks, the largest standalone PEM units then available, enabling configurations like the 20 MW Becancour electrolyzer commissioned in January 2021. These stacks facilitated modular scaling to multi-MW systems, with ongoing development toward 3 MW prototypes, reducing per-unit costs through higher throughput. For fuel cells, scalability emphasized modular HyPM-HD systems up to 150 kW per module, integrated into larger hybrid setups for heavy-duty applications.

Challenges, Criticisms, and Limitations

Economic Viability and Cost Barriers

The primary economic barrier to Hydrogenics' (PEM) electrolyzers stems from elevated capital expenditures (capex), driven by the need for catalysts such as and . In 2020, PEM stack costs ranged from 384 to 1,071 €/kW, significantly higher than alkaline electrolyzers at 242 to 388 €/kW, due to material intensity and lower manufacturing scale. These costs contribute to levelized expenses of approximately 4.65 USD/kg for PEM systems, compared to 3.69 USD/kg for alkaline alternatives, rendering PEM less competitive against fossil-based "gray" at 1-2 USD/kg without subsidies. A critical constraint is iridium scarcity for the reaction , with global annual production limited to levels supporting only about 3 GW of PEM capacity before supply bottlenecks emerge, exacerbating capex through price volatility—iridium traded at around 160 USD/gram as of recent assessments. Efforts to reduce iridium loading by up to 80% or develop substitutes show promise but remain pre-commercial, as PEM systems continue to incur higher operational expenses from efficiency thresholds around 60-70% versus alkaline's maturity in large-scale deployment. Projections indicate potential capex reductions to 63-234 €/kW for PEM by 2030 through manufacturing learning curves and scaling, yet current viability hinges on low-cost renewable (below 20 USD/MWh) and policy incentives, as unsubsidized from PEM exceeds 5 USD/kg in most scenarios. ' integration into post-2019 acquisition has facilitated investments in cost optimization, but systemic challenges like grid integration and add 20-30% to total system costs, underscoring PEM's niche suitability for high-purity, dynamic applications rather than broad economic displacement of established fuels.

Alkaline242–38852–793.69

Efficiency and Practical Constraints in Hydrogen Ecosystems

(PEM) electrolyzers, a core technology advanced by Hydrogenics, typically operate at electrical efficiencies of 65-75% based on the lower heating value (LHV) of produced, with specific systems requiring around 51-54 kWh per kilogram of . This efficiency reflects thermodynamic limits in , where overpotentials and ohmic losses consume a significant portion of input electricity, particularly at higher current densities needed for scalable production. In broader hydrogen ecosystems, these production efficiencies compound with downstream losses: compression for storage adds 10-15% energy penalty, (if used) demands up to 30% of the 's content, and or trucking transport incurs further leakage and boil-off, often totaling 80-90% overall dissipation from renewable input to end-use. conversion back to or mechanical work achieves only 40-60% , yielding round-trip system efficiencies of 20-40% for power-to-power applications, far below battery storage alternatives at 75-90%. Practical constraints exacerbate these inefficiencies, including hydrogen's low volumetric energy density—requiring compression to 700 bar or cryogenic storage at -253°C, both capital-intensive and prone to permeation losses through materials. PEM systems, reliant on scarce catalysts like iridium for oxygen evolution, face durability issues under variable renewable inputs, with degradation rates limiting operational life to 40,000-80,000 hours before significant efficiency drops. Infrastructure scalability remains hindered by the need for specialized high-pressure pipelines and stations, where global deployment lags due to upfront costs exceeding $1-2 per kilogram capacity annually. Safety protocols add operational overhead, as hydrogen's wide flammability range (4-75% in air) and embrittlement of metals necessitate redundant sensors and materials, increasing system complexity and reducing net efficiency in real-world deployments. These factors contribute to hydrogen's niche viability in long-haul or seasonal storage, where direct proves infeasible, rather than broad dominance.

Sector-Wide Skepticism and Alternative Technologies

The fuel cell and electrolyzer sector, including technologies like those developed by Hydrogenics, faces widespread skepticism from analysts and engineers due to fundamental thermodynamic inefficiencies and high lifecycle costs. Round-trip energy efficiency for systems—encompassing , storage, and reconversion via fuel cells—typically ranges from 25% to 40%, far below the 80% to 95% efficiency of storage and discharge cycles. This inefficiency arises from energy losses in compressing or liquefying for storage (requiring 10-30% of its content) and the inherent limitations of (PEM) fuel cells, which convert only 40-60% of 's to electricity. Critics, including reports from , argue that overhyping diverts resources from more viable direct pathways, potentially jeopardizing net-zero emissions targets by 2050. Alternative technologies, particularly advanced battery systems, have demonstrated superior and declines, undermining 's competitiveness in most applications. Lithium-ion batteries have achieved reductions to under $100 per kWh by 2025, enabling battery electric vehicles (BEVs) to dominate light-duty with 70-90% well-to-wheel , compared to 25-38% for vehicles (FCEVs). For grid-scale storage, batteries paired with renewables provide faster response times and lower levelized costs than , as evidenced by net analyses showing 's viability only in niche long-duration scenarios exceeding 100 hours, where pumped hydro or may still outperform. Emerging alternatives like solid-state batteries and flow batteries further erode 's advantages by offering higher densities and cycle lives without the safety risks of leakage or embrittlement in . Sector proponents acknowledge hydrogen's potential niches, such as heavy-duty trucking or requiring high-temperature heat, but skeptics like those at CleanTechnica contend that battery innovations—projected to reach 500-1000 Wh/kg densities by 2030—will encroach even on these, rendering widespread adoption uneconomical without massive subsidies. production costs remain above $3-5 per kg as of 2025, versus battery equivalents under $0.05 per kWh equivalent, exacerbating doubts about scalability amid and renewable curtailment issues. This skepticism has manifested in stalled projects and investor caution, with analyses indicating hydrogen's transport market share below 5% by 2030 barring policy distortions.

Market Impact and Legacy

Contributions to Hydrogen Infrastructure

Hydrogenics advanced primarily through its (PEM) electrolyzer systems, known as HyLYZER, which enabled scalable, on-site production of using renewable electricity, addressing key bottlenecks in development. These systems produced high-purity at pressures up to 30 bar without additional compression, facilitating integration into refueling stations, industrial facilities, and applications. By 2019, prior to its acquisition by , Hydrogenics had deployed multiple units supporting pilot-scale infrastructure, demonstrating feasibility for larger networks. A notable contribution was the supply of an electrolyzer for the Hydrogen Refueling Station at (CSULA), operational since 2016, which integrated production, compression to 700 bar, and storage to dispense for fuel cell vehicles, serving as a model for campus and urban refueling setups. In , Hydrogenics received $620,000 in government funding in 2017 to develop and commercialize projects, including contributions to public refueling stations in the , enhancing accessibility for fuel cell electric vehicles (FCEVs) and promoting regional corridors. Hydrogenics' technology also supported European deployments, such as a 2.5 MW PEM electrolyzer installation designed for scalability to 5 MW, producing for grid balancing and potential refueling, as detailed in industry assessments of systems. These efforts laid groundwork for integrating wind and into , with applications in hubs and ports to supply FCEVs and heavy-duty transport. Post-acquisition, the inherited HyLYZER platform powered the 20 MW Becancour facility in —commissioned in 2020 for —the largest PEM electrolyzer globally at the time, yielding up to 3,000 tons of annually for industrial decarbonization and pipeline injection. Such projects validated PEM technology's role in bridging intermittent renewables to reliable infrastructure, though economic viability remained constrained by high relative to gray alternatives.

' acquisition of Hydrogenics, completed on September 9, , for approximately $290 million, provided the company with established (PEM) stacks and electrolyzer systems, directly bolstering its pivot toward -enabled in heavy-duty applications. Prior to the deal, had been developing internal prototypes for over two decades, but Hydrogenics' commercial-grade modules—proven in transit bus and rail projects—enabled faster scaling and integration into ' broader zero-emissions portfolio, including electric vehicles (FCEVs) and on-site generation. This acquisition aligned with ' "Destined for Zero" initiative, launched around the same period, which emphasizes multiple decarbonization pathways beyond battery-electric systems, recognizing 's advantages in range and refueling for long-haul trucking where infrastructure limitations hinder pure . Post-acquisition, Hydrogenics' technologies were rebranded under and consolidated into specialized units, culminating in the 2023 formation of Accelera by , a dedicated zero-emissions that houses and electrolyzer operations derived from Hydrogenics. Accelera leverages these assets for gigawatt-scale electrolyzer deployments and modules targeting commercial viability by the mid-2020s, with projecting electrolyzer revenues exceeding $400 million annually as early as 2025 through partnerships for production. This integration influenced ' strategic investments, such as joint ventures for (e.g., with Purus in 2020) and alliances for ecosystem development, positioning as a complementary technology to internal engines adapted for fuel, rather than a sole reliance on batteries. The influence extended to Cummins' R&D prioritization, where Hydrogenics' expertise addressed key bottlenecks in hydrogen ecosystems, such as efficient for low-carbon fuel production, enabling Cummins to pursue end-to-end solutions from generation to . By 2023, Cummins exercised its option to acquire full ownership of Hydrogenics from co-investor , signaling sustained commitment amid rising demand for in sectors like rail and maritime, where fuel cells offer higher than batteries. This strategic embedding has diversified Cummins' electrification beyond diesel-electric hybrids, mitigating risks from battery constraints and supporting regulatory compliance for net-zero emissions by 2050, though real-world adoption hinges on cost reductions and buildout.
