Norwegian HydrogenPro, a provider of solutions for producing, storing, and distributing hydrogen from renewable energy sources, has received what is said to be the world’s largest electrolyser at its test facility at Herøya.

The electrolyser, which was manufactured at HydrogenPro’s factory in Tianjin, China, arrived at the Herøya test facility on 10 September, marking a milestone in the company’s history.
“This project is a critical milestone for large, green hydrogen projects. It requires substantial planning, rigging and the right equipment. This project is important to facilitate larger, green hydrogen projects, reducing carbon footprints and costs”, said HydrogenPro’s CPO Karoline Pafos.
According to Erik Christian Bolstad, the company’s CCO, the plant results will help optimise HydrogenPro’s delivery to one of the world’s largest factories for green hydrogen.
The electrolyser is expected to have an output of 1100 Nm3/h hydrogen at normal current density. This equals 100 kg of pure hydrogen per hour, which will set a new standard for the industry, the company claims.
The test aims to verify that the electrolyser produces the expected amount of gas per unit of time. During the test, HydrogenPro intends to use fluctuating electricity input from renewable energy sources and test several other parameters.
The electrolyser will be assembled and installed in the upcoming weeks, with the validation process initiated when possible.

what electrodes and how do you make chlorine from electrolysis
« on: 19/04/2014 08:44:44 »
I am new to this form so trust I am posting my question in the correct forum. I am an electrician by profession and live in Zimbabwe a country plagued with many problems, one being suitable water. I have to buy 5000 litres of water at US$60.00 a week which is VERY expensive.

I have built a grey water reclaiming pit which has been an ongoing project for several years. I think I have this almost right.

I would like to introduce chlorine produced via electrolysis run from Solar power. I have searched the internet and successfully managed to totally confuse myself.

Would someone be kind enough to point me in the right direction? I need to know the solution and the electrodes. The water is not for consumption.

Many thanks

Do you really need to treat the water for non-potable use? Perhaps use a sand filter?

A good fine mesh filter and perhaps a carbon filter, and you may be able to get most of the contaminants out of your water. Perhaps boil your drinking water.

Many people use chlorine bleach (sodium hypochlorite) for water treatment. Look up on the internet for instructions. I'm seeing recommendations of 5 ounces of liquid bleach (3-8%) per 1000 gallons of water treated. Much less if you get it in a powdered concentrate. Oh, it looks like the powdered form is often calcium hypochlorite, but it should still work. Look at swimming pool supplies.
