What other significant costs are there in producing hydrogen, such as servicing, maintenance, part replacements, consumables?

by admin | Mar 29, 2021 | Economic of H2 Production

All of these things are costs. The most significant of them are likely to be compressor maintenance and parts and replacement of electrodes for alkaline electrolyzers and membranes in proton exchange membrane electrolyzers. Regular maintenance may be one day per year,...

How does the round-trip efficiency of energy storage using hydrogen compare with energy storage using batteries and other energy storage technologies?

by admin | Mar 29, 2021 | Economic of H2 Production

The economic play for hydrogen today is not in producing electricity. The wholesale value of electricity is at near historical lows. Once hydrogen is produced from electricity, its highest value use is likely as a transportation fuel. The cost per BTU of...

In addition to electricity costs, what other costs are incurred in producing hydrogen through electrolysis?

Modest maintenance costs and the cost of feedstock water. Electricity is by far the highest cost...

What is the current cost of producing renewable hydrogen and how does that compare with the cost of hydrogen from fossil sources?

by admin | Mar 29, 2021 | Economic of H2 Production

Costs most sensitive to several factors: Cost of the electricity feedstock Capital cost of the electrolyzer Usage factor of the device (i.e., is it operating at full capacity all year, or operating over a small number of hours per year). Cherry picking the lowest...

How efficient are industrial-scale electrolyzers?

by admin | Mar 29, 2021 | Economic of H2 Production

Roughly 70% Efficient. It takes between 55-60 kWh of electricity to make a kilogram of hydrogen, which has about the same energy content as a gallon of...
