Perhaps , there could be another dozen names in coming days within Electrolyser / components manufacturing l!
Electrolysers could be in different capacities mini, micro, large, mega etc ranging from 60KW to 120 MW, though the largest single unit produced so far is of 24 MW capacity. one can have multiple units to meet large amount of Hydrogen requirement. Hydrogen is renewable energy which can be stored and used in various ways as discussed earlier at length in previous posts. Renewables like solar wind can not be stored. But then by electrolyser , we can convert solar wind energy to Green hydrogen which can used in different ways or can be stored and used later to produce electricity
let us come to electrolyser capacity.
1 KW= 1000 W
1MW= 1000 KW
1GW= 1000 MW
Our domestic house we live in normally is of 10 KW capacity.
There are small scale industries, MSME’s commercial business houses , large factories power requirement could vary widely depending upon it size.
Apart from Mega renewable power plants/ Electrolysers being planned by Reliance, adani , L&T, etc we have large factories , small scale industries planning to have small size electrolysers .
For example, when Green hydrogen becomes affordable,
if we look at future, even domestic houses can have roof top solar panel to produce electricity and have electrolyser to produce Green hydrogen by excess solar power in day time. Green hydrogen can be stored and can be used for domestic gas or to fuel your car. or even Green hydrogen can be converted back to electricity by a Fuel Cell in the night to produce electricity when solar power is not available.
So far as Mega electrolysers production capacity is concerned , there are only 6-7 manufacturers as mentioned in the article, though there could be many more to produce mini , micro, large catagories.
