Green Hydrogen
Plug Power
Leveraging the most abundant element in the universe, Plug was founded 25 years ago with the mission of powering the world using renewable energy. Plug Power has grown into the leading provider of green hydrogen with the world’s largest fueling station footprint. Following the development of the first commercially viable market for hydrogen fuel cell technology, customers turned to Plug to develop world-class hydrogen solutions that could make adoption simple. With its customers in mind, Plug built an end-to-end ecosystem with 50,000 fuel cell systems and more than 165 fueling stations for a range of customer applications. Plug is committed to developing effective and reliable end-to-end hydrogen solutions that allow customers to operate sustainably and efficiently.
Plug Advantage:
Zero-Emission Power
Hydrogen fuel cells (HFCs) produce no harmful emissions, eliminating the costs associated with handling and storing toxic materials like battery acid or diesel fuel. In fact, when fueled with pure hydrogen, the only by-products are heat and water, making fuel cells a zero-emission, sustainable power source. Hydrogen fuel cells are part of many well-planned corporate sustainability programs.
Robust Reliability
Hydrogen fuel cell technology has proven itself against tough conditions, including cold environments as low as -40 degrees F/C, weather environments like hurricanes, deserts, and winter storms, and even the hardworking business environments of material handling warehouses.
Improved Efficiency
Hydrogen fuel cells are generally between 40% to 60% energy efficient, according to the U.S. Department of Energy. In comparison, the typical internal combustion engine of a car is about 25% and thermal power plants are about 30 to 50% energy efficient.
Scalable
The advantages of using modular products such as fuel cells are profound: greater reliability and easier serviceability. But the most important of the fuel cell benefits may be scalability. These products may be engineered precisely to meet a variety of customer power needs, whether for on-road electric vehicles, material handling fleets, or stationary power.
Lower Operational Costs
Compared to batteries and internal combustion generators, fuel cells save money. They eliminate the need to change, charge, and manage batteries, subsequently reducing labor, time, space, and peak power demands. Additionally, simple maintenance and fewer site visits mean up to 84% lower operational costs when compared to combustion generators for stationary power. Robust reliability eliminates the need for quarterly site maintenance visits, keeping site personnel focused on their critical tasks.
Hydrogen Electrolyzers
Renewable Generation and Storage
Electrolyzers use electricity to split water into hydrogen and oxygen. Hydrogen storage captures the power of clean energy for later use. The remarkable potential for green hydrogen to reduce emissions is creating demand across many industries. Manufacturers with hard-to-abate processes, such as iron, steel production, and chemical refining, are looking to hydrogen as an alternative to coal and natural gas. Transportation, especially in the long haul and high payload and utilization applications, is looking to replace diesel with hydrogen. And communities around the world are demanding that hydrogen be blended into existing gas pipelines to make residential and commercial gas consumption cleaner and more efficient.
Hydrogen Fuel Cells
A Different Kind of Backup Power
Hydrogen fuel cell is an electrochemical power generator that combines hydrogen and oxygen to produce electricity, with water and heat as by-products, and can be used to power anything from commercial vehicles to data centers to communities. Hydrogen fuel cell technology offers the advantages of a clean and reliable alternative energy source to meet the growing demand for renewable and sustainable energy supply.
Recent advances in proton exchange membrane (PEM) electrolysis have made the process of electrolysis significantly more efficient in terms of both energy usage and operational costs. This, in turn, has made it much easier to couple electrolyzer systems with dynamic renewable energy sources like hydro, wind, and solar.
PEM hydrogen electrolyzers are safer, cleaner, smaller, lighter, and more responsive than alkaline technology alternatives. Utilizing pure water instead of corrosive potassium hydroxide means far less maintenance and a lower cost of ownership.
