PureH2 Hydrogen Electrolyser

Low and high-pressure hydrogen electrolysers

Pure Energy Hydrogen is a company committed to the design, development, and manufacture of low and high-pressure hydrogen electrolyzers. We offer our electrolyzer products and services globally all aimed at multiple industries including the renewable, oil & gas, metallurgical, glass, food, gold, and other applications.

Pure Energy Hydrogen was the first company in the world to install a completely offgrid hydrogen electrolyser system all owned by a community in 2005. Since then, it has installed electrolysers in Asia, the Middle East, Americas, and in many European countries. Pure Energy Hydrogen has an enviable proven track record as an expert in the hydrogen alternative fuel production, compression, storage and dispensing all of being used to your advantage.

We offer electrolyzer’s tailored solutions for hydrogen houses, businesses, farmers, refineries, green transport, energy storage solutions, gold and diamond mining, food processing, power station cooling and we aim at ensuring that as many applications of our hydrogen generator units use renewable energy.

Each of our electrolyser product is unique and built to your needs all with the latest innovations in hydrogen production, safety and operation. We offer small scale 0.5Nm3/h to large multi MW electrolysers.

Specification and Pricing


The price for a hydrogen electrolyser is dependant on size, technology and pressure output. It is possible to say that electrolysers costs vary from £40,000 to £250,000 for the small ones and multi-million pounds for the larger ones.

Quality Assurance

We produce excellent durable hydrogen electrolysers, all of which are CE marked. Our Hydrogen Electrolyser have a proven record of being installed under the most stringent weather conditions of the Scottish Isles (UK).

Installation, Supply & Management

Easy to install the hydrogen electrolyzer in a containerised solution. Suitable for intermittent electricity sources like solar electrolysers or wind and hydro. Electrical supply - 120/240 VAC, 400/440 VAC, 50/60Hz

Maintenance & Monitoring

5 year maintenance contracts available are available. Pure Energy Hydrogen also offer remote monitoring, allowing us to support customers and clients worldwide.

State-of-the-art manufacturing

At our state-of-the-art facilities, we manufacture, supply and deploy hydrogen electrolyzers in many different configurations, all of which can be installed on your hydrogen site.

We have different electrolyser size solutions, where both gases can be stored at different pressures such as atmospheric. But we also produce high-pressure electrolyzers at 5 bar, 10 bar, and 30 bars. Note that all our water electrolyzer comes with innovative control and management systems.

There are times where we have hydrogen electrolyzer for sale, whether they are PEM or Alkaline type. We take safety as the top of our development pyramid our team of hydrogen experts custom build electrolyser to your satisfaction and to maximise safety. The aim is to ensure that they are manufactured to the appropriate level of details.


Types of Hyrdogen Electrolysers

Pure Energy Hydrogen (PEH) is a hydrogen electrolyzer manufacture.

Our electrolyzer’s membrane and catalysts aim at taking advantage of a 19th-century electrochemical reaction invention to split water (H2O) into oxygen (O2) and hydrogen (H2) molecules. The end product is Hydrogen gas that can be stored and then used to fuel a fuel cell stack, internal combustion engines, cookers, boilers, heaters, and any type of hydrogen cars.

Both our Alkaline and PEM electrolysers produce industry grade hydrogen with extremely high gas purity ranging from 95% up to 99.999%.


Proton Exchange Membranes (PEM)

Hydrogen electrolyzers for renewable energy

Pure Energy Hydrogen was the first entity in the world to have provided a community hydrogen production electrolysis solution and to announce that the electrolysis unit was directly connected to a wind turbine.

We deploy and operate electrolyzers that can be connected to a renewable form of energy source or directly connected to the grid. We can supply a wide range of hydrogen flow including 0.5 Nm3/h, 1 Nm3/h, 2 Nm3/h, 5 Nm3/h, 16 Nm3/h, and 200 Nm3/h and above. Other configurations are also possible and some of these are summarized below.

Home electrolyzer for universities and businesses

Our home electrolyzers have found their hydrogen homes in universities at a global level. The home electrolysis kits sold to higher education organisations have been used as laboratory equipment for training and teaching.

Home hydrogen electrolysis production can also be used to fuel vehicles, with stacks as small as 0.5 Nm3/h and up to 2 Nm3/h. A small electrolyser can, therefore, be used with a hydrogen compressor to fill a vehicle or a quad. Home electrolysers have also be used to produce hydrogen for cooking and heating purposes.
