Wilo, a global name in pump manufacturing, now has solar panels on the roofs of all of its buildings to enable green hydrogen generation through electrolysis.
The stored hydrogen is then used as needed by passing it through platinum-catalysed fuel cells, which turn the hydrogen passed through them into green electricity to run Wilo's operations.
The H2Powerplant is offered in four sizes, with the capacity to produce power equivalent to the yearly consumption of three, five, or 20 households.
Fuel Cell Works reports that this technological approach is enabling companies to accelerate the migration to clean energy from existing infrastructure without having to start from scratch.
Hydrogen, which can be stored for prolonged periods, is now being increasingly recognised as the superior energy storage option amid supply chains of raw materials such as platinum group metals (PGMs) also being increasingly also being elevated to the rank of decarbonising champions.
Key contributors are platinum-based proton exchange membrane (PEM) fuel cells, which are platinum catalysed amid green hydrogen generation and demand rising significantly in particularly China.
What is seen as urgent is that the hydrogen fuel cells industry uplifts itself fast to enable it to progress more rapidly into the mass market.
The peaks and valleys of renewable energy supply are best balanced out by stored hydrogen or hydrogen compounds, Heraeus Precious Metals executive vice-president business line systems Dr Philipp Walter spelt out during a Zoom interview with Mining Weekly. (Also watch attached Creamer Media video.)
"I believe every time it comes to dealing with hydrogen, platinum group metals have an advantage," Walter added.
Heraeus' virtual hydrogen talks involved inputs from Ulm and TU Wein University professor Dr Christian Mohrdieck, Freudenberg e-Power Systems Clean Energy Consulting's Dr Manfred Stefener and UFI Hydrogen's Marco Lazzaroni amid an important spotlight being shone on the extent to which platinum-catalysed fuel cells will drive future hydrogen demand.
The Germany-based precious metal and technology company Heraeus has had a long-standing association with South Africa, where its local entities include a marketing and sales office in Boksburg and a platinum group metals chemical compounds production and refinery site in Gqeberha.
Mining Weekly can report that the group's sales of PGM-based electric catalysts for hydrogen generation, which peaked in 2023, are back up again in 2025 owing to increased demand.
A hydrogen price of €5/kg to €6/kg was regarded as a tipping point by the panel, which sees no way around hydrogen owing to its versatile usage and water being the feedstock raw material for making hydrogen, which can be stored for a day, a week, a month, a year or more.
The amount of water needed for green hydrogen production is similar to that required for grey hydrogen, averaging about 10 to 19 litres per kilogram.
It's important to understand that the market for green hydrogen is already there because the world is consuming 100-million tons of hydrogen a year that are "polluting like hell", the French company Lhyfe has emphasised.
Lhyfe founder and CEO Matthieu Guesné is adamant that "there's nothing that's easier to do when decarbonising a customer, a plant, an industrial player, than switching from grey hydrogen to green hydrogen", so that's what this publicly listed company is doing.
Mining Weekly: Why is hydrogen seen as the superior energy storage option?
Walter: If you have renewable energy, you have ups and downs, peaks and valleys in terms of supply, and the best way to store energy, in this respect, is hydrogen, or compounds of hydrogen. You need chemical energy storage for these kinds of intermittent energy ...
