Clean Power Hydrogen (CPH2) launches membrane-less electrolyzers with cryogenic programs to separate hydrogen and oxygen. It manufactures it within the United Kingdom and collaborates with different firms for manufacturing in Germany and New Zealand. It says it expects 4 GW of mixed manufacturing capability by 2030.
CPH2 launches an electrolyzer with out membranes that’s reported to compete with proton change membrane (PEM) electrolysis when it comes to effectivity and price.
“Our stack is quite simple: chrome steel solely, in chrome steel,” mentioned CPH2 CEO Jon Duffy pv journalwhich provides that the know-how is simple to scale.
The system mixes potable water with hydroxide ions (electrolytes) into the stack, the place a chemical response happens, producing a combination of hydrogen and oxygen gasoline..
The moist gasoline enters the dryers, the place the desiccant removes the water from the blended gasoline stream. The gasoline then continues its journey to the cryogen for separation. Oxygen melts at roughly -200 C, leaving pure hydrogen as a gasoline and pure oxygen as a liquid.
“Cold hydrogen gasoline, liquid oxygen, and the long run blended gasoline THEN via a patented three-stream warmth exchanger. As the oxygen regasses and the hydrogen leaves as a gasoline, it precools the incoming blended gasoline,” mentioned Duffy. “By the time the blended gasoline reaches the underside of the warmth exchanger, the oxygen is already liquid.”
According to Duffy, the system is secure, “in all probability safer” than PEM electrolyzers.
“Electrolyzers produce a combination of gasoline and oxygen,” Duffy mentioned pv journal. “If you ensure that there is no such thing as a supply of ignition … there may be much less threat than PEM electrolysis, as a result of the membranes that injury are often invisible and harmful.”
The new electrolyzer makes use of much less stack vitality than PEM electrolysis, as a result of there is no such thing as a must drive electrons via membranes. However, it nonetheless requires extra energy for the cryogenic separation course of. It doesn’t use any essential uncooked supplies. More than PEM, it requires dryers and a low temperature system.
“The cryogenic is successfully only a vacuum cooled liquid nitrogen. All the additional components are fairly customary items of apparatus,” Duffy mentioned.
CPH2 has already put in a number of small check items for purchasers. It is now accelerating its trials in varied geographies.
“We have a 0.5 MW system TESTED … we hope to have megawatt programs at prospects’ websites finish THIS 12 months, begin subsequent 12 months,” mentioned Duffy. “We are within the last testing part. When shoppers order our electrolyzers, they are going to be delivered in 12 to fifteen months.”
The firm owns the patent and mental property and collectively with different firms to develop and commercialize the brand new system.
“We can license our know-how and assemble the electrolyzers ourselves on the identical time,” mentioned Duffy. “We will attain 1 GW manufacturing capability by 2030 for ourselves, and three GW from our licensed companions.”
CPH2 has signed agreements with Kenera Energy Solution, a subsidiary of a Scottish-German firm.
“They have an enormous manufacturing base in Germany, and they will begin making electrolyzers subsequent 12 months. We additionally signed a partnership with Fabrum in New Zealand, which offers us with the cryogenic system and is already producing this 12 months for markets of Australia and New Zealand,” mentioned Duffy. “We can even collect and ship on the finish of the 12 months. We are additionally searching for a brand new location, presumably in Northern Ireland, to extend manufacturing. “
If the corporate can show that its enterprise mannequin works in Germany and New Zealand, it is going to work copy and paste the blueprint to different markets.
