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 "polluting like hell", the French company Lhyfe emphasised this week as it drew attention to the steps it is taking to convert grey hydrogen - and the use of proton exchange membrane (PEM) technology to do so also got a word in edgeways, which is music to South Africa's ears as PEM and platinum group metals (PGMs) go hand-in-glove.
Lhyfe is a France-based public company that sells its green hydrogen at a price comparable with fossil fuels across Europe, which currently consumes seven-million tonnes of grey hydrogen, a major carbon dioxide (CO2) emitter.
At question time, Sasol's production of 2% of the world's grey hydrogen also came into the picture.
"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 we're doing," Lhyfe founder and CEO Matthieu Guesné outlined during the online presentation covered by Mining Weekly.
"Decarbonising existing industry is as important as decarbonising mobility because 23% of CO2 emissions are linked to energy usage by industry, so it's important to understand that the market for green hydrogen is already there," Guesné pointed out.
The 100-million tons of grey hydrogen emits a billion tons of CO2.
"Whether you believe that green hydrogen is the silver bullet of energy transition or not, hydrogen is a necessity, and it has a tremendous market, and it needs to decaronise. Green hydrogen is 20 to 35 times less intensive in terms of CO2 emissions, so that's a good solution.
"It's as important to decarbonise industry as it is to decarbonise mobility, because 23% of the CO2 emissions that are linked to energy usage in the world are linked to industry, and the same percentage, 23%, is linked to energy usage for transportation, so it's the same challenge to decarbonise transportation as it is to decarbonise industry," Guesné noted.
A lot of hydrogen is needed because of its use in the production of glues, inks, paints, fertilisers, explosives, and many other items.
"If you go to IKEA and you buy a shelf, 60% of the shelf is made from glue and particle wood that is glued. That glue is made from methanol, which is in turn made from carbon and hydrogen.
"Basically, with six chemical compounds, the chemical industry can produce everything, so you have soda, chlorine, nitrogen, carbon, and hydrogen, and those chemical compounds, form the basic elements for doing plastics, glue, inks, paints, explosives, and fertilisers, all produced from those basic compounds, and that's why you need a lot of hydrogen," Guesné reiterated.
Displayed on the screen was a Lhyfe hydrogen production plant that purifies seawater ahead of electrolysing it into green hydrogen. Shown as how this plant is connected to a wind farm that has wind turbines dedicated to the hydrogen production.
Lhyfe's commercial scale plant has made more than 500 deliveries of green hydrogen to 50 customers, using a fleet of nearly 70 containers. The company employs 200 people and operates in 12 countries across Europe and Canada.
"We did a lot of hardware and software to achieve that. But we did not manufacture the components themselves. We bought the components from companies in Europe to do our plant.
"We did the funding and construction of the plants. We use our money, or bank money, to fund the plant, and we operate the plant. We have our own training centres for our own operators, and then we deliver to customers.
"We have a sales force that sells each and every kilogram of green hydrogen that we produce. The plant is running and it's delivering its hydr...
