For years , the solar energy sphere has grappled with interseasonal energy storage . The ability to rein in the surplus solar energy of summer month for use during the winter has remain an problematical goal , with existing answer like batteries falling brusk due to prohibitive costs and limited lifespans . Hydrogen , meanwhile , despite its neat - burning belongings , has been sidelined due to inefficiency and high costs .
Photoncycle — a startup emerge from the deepness of an atom smasher in Oslo Science Park in Oslo , Norway — has been work on a solution . With a vision as bright as the summer Lord’s Day , the startup claims its satisfying hydrogen - based technology can store energy more expeditiously inan ammonia synthesis nuclear reactor . The claim is this technical school does the storage more cost - in effect than any battery or liquified hydrogen solution on the market .
“ Lithium - ion batteries utilize dear metals . Our material is super bum : To stack away 10,000 kW - hours , it be around $ 1,500 , so it ’s almost nothing . In improver , our storage result is 20 times the density of a lithium - ion bombardment , and you do n’t turn a loss the current , ” founder and CEO Bjørn Brandtzaeg explains in an interview with TechCrunch . “ That means we have a scheme where you’re able to contain energy over fourth dimension , enabling seasonal warehousing . It ’s a completely different affair than traditional battery . ”
Photoncycle employs water and electricity to farm H . That in itself is n’t rare if you ’ve been following fuel cell vehicle applied science . However , the society ’s approach incorporate an groundbreaking machine : a two-sided high - temperature fuel cell . This ripe fuel cellular telephone can make H and bring forth electricity within the same unit .
The essence of Photoncycle ’s invention lies in its treatment of atomic number 1 . They process the hydrogen and then employ its technology to convert and store it in a solid form . The company claims this warehousing method acting is not only safe , owing to the non - inflammable and non - volatile nature of the whole state , but also extremely effective . It enable H memory board at densities approximately 50 % greater than liquid hydrogen , presenting a significant advancement in hydrogen storehouse solution . These innovations work the cornerstone of Photoncycle ’s scheme , facilitating good and dense hydrogen storage , which the company says is a vast step forward in energy technology .
Current clean energy solutions such as rooftop solar power are fix by inconsistent supply due to the unpredictable nature of weather weather . A rich , reusable energy storehouse solution could bridge over these timing , ensuring a stable energy provision when these renewable source find unavoidable intermittent period .

Great in theory , but not without its own challenges .
“ The Netherlands is the country in Europe with the gamy density of rooftop solar . We are seeing a massive ramp now because of high energy damage ; everyone wants solar on the roof , ” Brandtzaeg state . He adds , however , that this method can backlash for householder : “ In July last yr , in the Netherlands , in the middle of the day , you had to pay € 500 a megawatt hour to export your electrical energy . ”
put the energy storage along with the star sign sire the power in effect let houses go off - grid . Photoncycle pronounce it has quiz and work the principal component part of its solution — the next footstep is to integrate it into a arrangement . If successful , the company say it can seriously take exception Powerwall , Tesla ’s atomic number 3 - ion assault and battery solution .
“ This is a relatively complex system — that ’s why we have so many PhDs in unlike disciplines solve on this . The reason why Elon Musk said that H is dazed , is that when you commute electricity to hydrogen and back , you are losing quite a second of energy , ” Brandtzaeg says . He believes his ship’s company can sour this bug into a feature . “ In a residential setting where 70 % of energy motivation are stir up , there is an opportunity to use that extra heat to supply hot pee . We will place market place where citizenry are using natural gas for warming at the moment and then supercede the gas kettle in the house using the live water - found infrastructure . ”
Brandtzaeg ’s confidence regarding the concept ’s in operation fabric is compelling . He gestured toward a small mock - up of their mathematical operation plant within their lab , scaled down to the size of a railcar battery . Brandtzaeg believes this grading should be problem - free , mention it as the primary reason they felt confident move onward with the project .
When it come to power delivery , it takes a little while for the hydrogen to generate electricity , so while it is spooling up , the society bank on an intermediary , more conventional , electric battery for load reconciliation . The firm certainly has investors ’ attention : Photoncyclejust advance $ 5.3 million ( € 5 million ) to build its first few power warehousing equipment in Denmark , which Photoncycle has chosen as its trial market .
“ We could have call forth 10 times as much as we did , given the interest . But after this rise , I ’m still a legal age proprietor , ” Brandtzaeg say . “ I want to keep control over the business as long as potential and not raise more upper-case letter than we require to bring this Robert William Service to market . ”
