Store the season with Photoncycle
The year-round solar energy system that can save up to 50% of your heating and electricity cost
Estimate savingsPhotoncycle solves the core problem with solar energy - its seasonality
Lots of sunshine
Solar panel owners sell electricity cheap in the summer
or not enough for months
..and paying high prices for the grid in the winter
- Be powered by summer sunshine year-round with solid-state hydrogen energy storage with capacity of more than 750x regular Li-ion battery
- Save on your bills from the first month, with freedom from high energy prices
- Balance the grid - store energy locally when there’s sun, sell it later when prices are peaking
- Photoncycle system includes processing unit, solar panels, and an underground storage of 10.000 kWh - enabling generation, storing, and trading of energy.
Energy autonomy for a transparent price
Innovative energy system, beautifully designed
Breakthrough hydrogen energy storage of 10 000 kWh - 20X as dense as a lithium battery
Scandinavian design - minimalist, space efficient and quiet
Have it installed in one day, with no retrofitting inside the house if there is water-based heating
Year-round autonomy, balancing the energy system
Meet your heat and power needs year-round with home-grown, renewable energy
Reduce pressure on the grid by storing energy locally when the sun is shining and prices are low
Have peace of mind that you will stay powered if the grid goes down
Predictable spend, capitalising on volatility
Fixed energy costs, no matter what your neighbour pays per kWh
Automatically sell surplus energy when prices are high to maximise your return
Reduce the cost of Photoncycle significantly with profits from energy trading
Be part of the future of energy
Estimate savings
01 Solar energy generation
Solar panels convert the photons from the sun to electricity. On average, a house with 100 m2 roof area can produce 20-25 MWh of electricity in Northern Europe.
This electric energy is circulated through the inverter to be used in the house, stored for winter, or used for trading when the prices peak.
02 Production of hydrogen
The surplus energy is used to produce green hydrogen out of water in the fuel cell. Here, a reversible fuel cell is used to both produce hydrogen in the summer and generate electricity from the hydrogen in the winter.
03 Hydrogen processing
Through our patented technology, the hydrogen is processed to be stored in a solid state approximately 20 times denser than in a lithium-ion battery.
04 Storing energy for winter
Ready to be used in the winter, in an underground storage unit. The unit can store up to 10 000 kWh of energy, 700x that of standard home batteries.

Frequently asked questions
The Photoncycle system provides your home with electricity, heat, and hot water via solar energy, year-round. It includes compact underground energy storage based on our proprietary, patented solid hydrogen technology, that can store up to 10 000 kWh. There is also an overground unit for energy processing (including a lithium-ion battery for short-term storage), and solar panels (if required). Additionally, we manage the trading of surplus energy production for you.
The Photoncycle system stores energy when your solar panels produce a surplus or when there are negative prices in the grid. When prices peak, you can utilize the stored energy or sell it as electricity back to the grid. Your monthly cost for energy (including electricity and heating) through Photoncycle is fixed, and you will receive a share of the trading profits.
Compared to alternatives on the market, there is no high upfront investment - you can start saving money and CO₂ from day one. When ordering the system, you pay a refundable deposit. Monthly, you pay a fixed fee, which will be reduced by the revenues from energy trading. It is estimated, that you can save between 10 to 50 percent of your current energy costs with Photoncycle subscription.
You can sign up for the waitlist, and leave your contact information. We will contact you when the Photoncycle system becomes available for pre-order.
Yes, Photoncycle is ideal for replacing any water-based heating system. The system can be easily installed in a house with a water-based heating system, such as gas and oil-based heating, district heating, or water-based floor heating. In these cases, no retrofitting inside the house is needed, and the Photoncycle system can be installed in one day.
