How do hydrogen electrolyser systems work?

Electrolyser systems offer a non-polluting, renewable energy solution to creating hydrogen. Using electricity (from grid or renewable sources), electrolysers are used to split water to create oxygen and hydrogen gas. Released in this way, hydrogen gas can be used as hydrogen fuel. Electrolysers can vary in size to suit their application – from small on-site hydrogen production to large-scale system and storage to power large facilities. Electrolysis of water is the process of using electricity to decompose water into oxygen and hydrogen gas. Hydrogen gas released in this way can be used as hydrogen fuel, or remixed with the oxygen to create oxyhydrogen gas, which is used in welding and other applications


How our innovative hydrogen solution works

tpgroup’s solution seeks to utilise surplus grid energy or ‘green’ renewable energy sources, such as wind farms and solar panels, to power onsite large-scale systems which generate hydrogen and store the gas for conversion into other energy sources. This modular approach means it can be tailored to specific requirements as well as to the environment.


tpgroup’s proposed solution (see below) provides the capability to deliver up to 700 Bar high pressure pure H2 (not shown is extra available H2 storage if required).

Our modular hydrogen electrolyser systems

Using its proven expertise in systems engineering and packaging, tpgroup can configure the hydrogen generation equipment to a customer’s requirements whilst delivering a rapid and dynamic response to the grid operators’ variations in energy generation output.  

Fully certified to CE or UL standards as required, these modular systems are designed with integrated control systems for seamless integration into a customer’s application and can be supplied for installation indoors or outside – for onshore or offshore.

Whilst the focus of hydrogen generation is on power to gas energy storage, it also offers a greener energy for vehicle refuelling, industrial processes and the backup power market – used in conjunction with fuel cells this provides a viable alternative to fossil fuels.

Why our hydrogen electrolyser systems?

As renewable technologies continue to evolve, they offer new ways to meet some of the challenges ahead. This includes the scale of hydrogen generating units where there is now the potential to operate with smaller generating units. This offers two critical benefits:

Smaller generating units require less infrastructure and can be located closer to user demand. As well, those units can be operated as modules and joined together to offer a more flexible and scalable solution.

Electrolyser-based generation systems fit well within this landscape as they can be operated in compact and even mobile packages. This tested technology offers the potential of being able to operate across a range of industries including on offshore oil or gas platforms, inside factory facilities or even in the car park outside a public building such as a hospital.

Whilst this flexibility offers many advantages, it still presents a challenge to system engineers to configure and optimise the solution to best fit the user needs. And hydrogen production isn’t without risk – you need to assure that the safety and performance of these systems have been designed and developed by an experienced partner like tpgroup.

We bring 50-years of experience of such systems, packaged for the most demanding of uses and environments, to drive these innovative solutions into everyday use.
