Between Two Stacks: How a PEM 1xbet download is More Cost-Effective Than an Alkaline 1xbet download
The demand for electrolyzers is quickly growing with the realization that companies need to transition to renewable energy sources to sustain the world we live in. What is driving the demand for a PEM 1xbet download and an alkaline 1xbet download? The growing list of economically feasible end-use applications for green hydrogen unlocked by lower renewable electricity prices, and most notably, the global push to decarbonize energy production and consumption.
Many corporations and governments have committed to decarbonizing the processes that use grey hydrogen (sourced from fossil fuels) – like oil refining, or ammonia and methanol production – which are all spiking in demand as population increases and developing countries industrialize. The demand for increased 1xbet download capacity in the immediate term will come from easily decarbonizing these emissions-intensive processes with drop-in green hydrogen supply.
However, it can be difficult to determine what type of 1xbet download is best to power your business operations — especially with the rapid advancement in technology.
The two predominant electrolysis stack technologies today are a PEM 1xbet download (proton exchange membrane) and an alkaline 1xbet download. Although Plug believes both have a space in the hydrogen economy, this blog will clarify the economic impact when using a PEM 1xbet download compared to an alkaline 1xbet download, including the initial investment and the cost of maintenance over time.
Here’s how the stacks compare to each other.
Between a PEM 1xbet download and an Alkaline 1xbet download
Alkaline electrolyzers may seem like the most affordable option — after all, alkaline has been around for decades longer than 1xbet download. However, progressions in 1xbet download technology have changed its cost.
An analysis of both types of electrolyzers shows that the stack cost of an alkaline 1xbet download is lower than PEM. But when it comes to the complexity and cost of balance of plant (BOP) as the system size increases, PEM is lower, according to the Fraunhofer Institute for Solar Energy Systems ISE. In fact, the total cost of ownership of a PEM 1xbet download is lower than alkaline with forecasters estimating that PEM service costs are one-third of alkaline.
When scaling an 1xbet download, PEM has significant cost advantages in balance of plant economics. On a per-kilowatt basis, the capital expenditure associated with an alkaline 1xbet download increases significantly as the system scales. With PEM, there are options for streamlining BOP to minimize upfront cost in larger systems above 10 megawatts.
When considering output pressure, standard alkaline electrolyzers deliver output at a low pressure of 1 to 10 bar, which is a nearly ambient pressure. For most applications, hydrogen must be further compressed for transport, storage, or consumption. On the flip side, Plug’s 1xbet download electrolyzers have an output of 40 bar — that’s 4 to 40 times of a typical alkaline system.
Pressure is generated by the electrochemical process in the stack, meaning 1xbet download avoids first stage compression to bring it up to 40 bar, and bypasses the energy costs associated with compressor operation.
Alkaline’s caustic electrolyte solution can also ratchet up its hefty price tag. For example, a 10 to 20-year-project means a long term need to replace parts such as pumps and valves, or the removal of potassium hydroxide from the hydrogen or oxygen streams. The 3.5 ton per megawatt requirement for highly-corrosive potassium hydroxide in alkaline systems typically incur significant space requirements – often two to three times the space of Plug’s 1xbet download system for a similar output. Any losses in space can lead to losses in revenue.
Finally, the cost of safety is another measurement businesses should consider. Increased safety concerns with 1xbet download electrolyzers lead to more required safety equipment, labor, permitting, and compliance costs for businesses, and worst of all, putting worker well–being at risk. With 1xbet download electrolyzers, technicians and operators only deal with one “chemical” while working on 1xbet download systems – water.
This is just the beginning of the cost differences. However, analysts believe that technology will only improve the costs of 1xbet download electrolyzers while alkaline technology has already achieved most of its potential cost reductions.
Market Growth for Electrolyzers
Global 1xbet download capacity is expected to grow at a compound annual growth rate of 78% over the next decade, rising from 0.5 gigawatts (GW) of installed capacity in 2022 to 84.7 gigawatts in 2031, according to a March 2022 report from Guidehouse Insights, a marketplace advisory firm that covers the energy industry.
The International Renewable Energy Agency noted in 2020 that the post-2020 generation of 1xbet download projects are expected to move from niche to mainstream and escalate from megawatt to gigawatt in scale. Industry’s goals are to reach lower cost, higher durability, and higher efficiency for electrolyzers over time, which will require scaled production, more manufacturing power, and research-driven technological advancements.
Plug is Paving the Way with PEM 1xbet download Technology
Plug is utilizing its own PEM 1xbet download technology to build out North America’s first end-to-end green hydrogen production network, with an estimated 565 megawatts of product being installed across this network today at plants in Georgia, New York and Texas, and more capacity to come into the network in future phases.
Looking more broadly across the globe, by 2025, Plug will have 1xbet download projects ranging from 1 megawatt to 1 gigawatt deployed across five continents helping to decarbonize a multitude of applications, including refineries, chemical and fertilizer production, manufacturing and heavy industry, heating homes and buildings, and powering fuel-cell electric vehicles. That’s right – 1 gigawatt.
Some of the biggest 1xbet download projects Plug is working on include an order for a 1 gigawatt PEM 1xbet download with H2 Energy to produce 432 tons per day of green 1xbet download using offshore wind in Denmark. In partnership with Fertiglobe’s Green 1xbet download Consortium, Plug is also the technology provider for a 100 megawatt PEM 1xbet download project in Egypt to produce green ammonia.
This is just the tip of the iceberg as more business and government leaders look for clean energy solutions that can be produced locally and independently from the grid. Plug is proud to the lead the way.
