## About

Based in Oslo, Norway, and founded in 2020 by CEO Bjorn Brandtzaeg, Photoncycle AS, d.b.a Photoncycle, offers an energy platform specializing in solar-powered systems to address the challenges associated with seasonal variations in electricity generation and consumption in residential settings. In March 2026, Photoncycle AS raised EUR 15 million in series A funding from NordicNinja VC, Voima Ventures, Lifeline Ventures, Eviny Ventures, Luminar Ventures, and Momentum Partners.

Photoncycle AS develops technology and business concepts to enable sustainable solutions for the energy system, particularly in regions with significant seasonal variation in photovoltaic (PV) generation and demand. Photoncycles use an electrolizer to store surplus electricity from rooftop photovoltaic (PV) systems and the grid for long-term storage systems. This system converts green hydrogen produced from water and electricity into a solid state, offering a gravimetric energy density of 3.5 kWh/kg—higher than traditional lithium-ion batteries. The storage system enables users to capitalize on seasonal fluctuations in energy prices, importing electricity when prices are low and exporting it when prices are high.

The company plans to use the March 2026 funding to expedite its commercial growth in Denmark and the Netherlands.
