Photoncycle targets low-rate energy storage with a artful hydrogen resolution | TechCrunch – Techcrunch
For years, the solar energy sector has grappled with interseasonal energy storage. The potential to harness the excess solar energy of summer season months for use in some unspecified time in the future of the iciness has remained an elusive purpose, with existing alternatives take care of batteries falling immediate because of prohibitive expenses and tiny lifespans. Hydrogen, within the meantime, despite its fine-burning properties, has been sidelined because of inefficiency and high expenses.
Photoncycle — a startup rising from the depths of an accelerator in Oslo Science Park in Oslo, Norway — has been working on a resolution. With a imaginative and prescient as vivid because the summer season solar, the startup claims its stable hydrogen-essentially essentially based mostly expertise can retailer energy more efficiently in an ammonia synthesis reactor. The utter is that this tech does the storage more rate-effectively than any battery or liquid hydrogen resolution within the marketplace.

“Lithium-ion batteries use dear metals. Our cloth is colossal cheap: To retailer 10,000 kilowatt-hours, it expenses around $1,500, so it’s nearly nothing. As effectively as, our storage resolution is 20 events the density of a lithium-ion battery, and you don’t lose the recent,” founder and CEO Bjørn Brandtzaeg explains in an interview with TechCrunch. “That draw we occupy got a system where you will more than seemingly be in a field to own energy over time, enabling seasonal storage. It’s an completely various factor than worn batteries.”
Photoncycle employs water and electricity to make hydrogen. That in itself isn’t queer at the same time as you’ve been following gas cell car expertise. However, the firm’s potential comprises an modern twist: a reversible high-temperature gas cell. This evolved gas cell could make hydrogen and generate electricity contained within the same unit.
The core of Photoncycle’s innovation lies in its treatment of hydrogen. They job the hydrogen and then relate its expertise to remodel and retailer it in a stable create. The firm claims this storage draw isn’t most involving protected, owing to the non-flammable and non-explosive nature of the stable utter, however furthermore extremely efficient. It enables hydrogen storage at densities roughly 50% larger than liquid hydrogen, presenting a important advancement in hydrogen storage alternatives. These improvements create the cornerstone of Photoncycle’s system, facilitating protected and dense hydrogen storage, which the firm says is a mountainous step forward in energy expertise.
Unusual fine energy alternatives similar to rooftop solar energy are tiny by inconsistent supply due to the unpredictable nature of climate prerequisites. A sturdy, reusable energy storage resolution could bridge these timings, ensuring a stable energy supply when these renewable sources bump into unavoidable intermittent sessions.
Good in view, however not without its have faith challenges.
“The Netherlands is the nation in Europe with the good density of rooftop solar. We are seeing a broad ramp now because of high energy prices; everyone desires solar on the roof,” Brandtzaeg says. He provides, nonetheless, that this kind can backfire for home homeowners: “In July closing year, within the Netherlands, within the center of the day, you had to pay €500 a megawatt hour to export your electricity.”
Inserting the energy storage along with the home generating the facility effectively lets homes drag off-grid. Photoncycle says it has tested and worked the major parts of its resolution — the subsequent step is to mix it precise into a system. If worthwhile, the firm says it will perchance severely venture Powerwall, Tesla’s lithium-ion battery resolution.

“That is a beautiful advanced system — that’s why we occupy got so many PhDs in various disciplines working on this. The motive Elon Musk acknowledged that hydrogen is lifeless, is that in case you convert electricity to hydrogen and lend a hand, you could to presumably be shedding rather a minute bit of energy,” Brandtzaeg says. He believes his firm can flip this bug precise into a feature. “In a residential surroundings where 70% of energy desires are heating, there could be one more to make use of that excess warmth to present scorching water. We are going to target markets where other folks are the use of pure gas for heating for the time being and then substitute the gas boiler within the home the use of the present water-essentially essentially based mostly infrastructure.”
Brandtzaeg’s self perception regarding the view’s operational framework is compelling. He gestured in opposition to a miniature mock-up of their operations plant interior their labs, scaled all the draw down to the size of a car battery. Brandtzaeg believes this scaling desires to be snarl-free, citing it because the major motive they felt confident transferring forward with the venture.
When it involves energy transport, it takes a short time for the hydrogen to generate electricity, so while it is miles spooling up, the firm relies on an middleman, more extinct, battery for load balancing. The firm with no doubt has merchants’ consideration: Photoncycle appropriate raised $5.3 million (€5 million) to create its first few energy storage devices in Denmark, which Photoncycle has chosen as its take a look at market.
“We could occupy raised 10 events as powerful as we did, given the interest. However after this elevate, I’m peaceful a majority owner,” Brandtzaeg says. “I wanted to withhold management over the substitute as lengthy as imaginable and never elevate more capital than we must bring this provider to market.”
