idyl.tower
The Long-Term Storage for Long-Term Impact.
Our large-scale energy-storage system supplies electricity, heat, and cooling – highly scalable and environmentally safe.
Power to the People – Energy Storage Meets Holistic Sustainability.
What’s missing from the energy transition to finally and fully leave fossil fuels behind? The answer: highly scalable and environmentally friendly long-term storage solutions. Our large-scale energy storage system, the idyl.tower, offers exactly that – and more. In addition to short-term and seasonal long-term storage, it also functions as a tri-generation storage that enables sector coupling – by supplying electricity, heat, and cooling.
Our approach is to think about energy storage holistically. That’s why we use water and sand as storage media: both are ecologically safe, risk-free to use, and enable regional supply chains. This strengthens independence from other continents.
Limitations are a thing of the past: Thanks to its modular design, individual units can be expanded into an idyl.cluster, allowing for unlimited increases in performance and capacity. With this globally deployable key technology, we create the potential for more purpose, more impact, more power to the people – and unite economy, ecology, and social consciousness.
Inspired by Nature: The Thermal-Gravitational Energy Storage System.

Our storage technology follows a simple natural principle: we use heat, cold, pressure, and gravity to generate airflows – the same principle that creates wind on Earth. We use these airflows to drive turbines and reconvert the energy into electricity. That’s why we refer to the idyl.tower as a thermal-gravitational storage technology.

Storage Media.
Our energy-storage system uses water and sand as storage media – with key advantages:
- Accessible via regional supply chains – cost-effective, reduces carbon footprint, and strengthens independence from other nations and continents
- Not based on critical resources
- No harm to fragile ecosystems during extraction
- Can always be returned to nature without producing waste

Design.
The exterior idyl.tower design is still in development. The illustrations shown here are for contextual purposes only. Our goal is to make design and user experience connecting elements: especially through biophilic design (e.g., urban gardening, vertical farming), we aim to bring together neighborhoods, nature, and progressive technologies – realizing our vision for sustainable, inclusive urban development.

Let’s make our energy infrastructure future-proof: With regional supply chains and strong scalability, we create sustainable independence.

The idyl.tower connects producers and consumers while providing the flexibility needed in energy infrastructure.

We power access.
With the Green Deal, the EU is on a historic mission to become the first climate-neutral continent by 2050. To move away from fossil fuels, we must expand sustainable energy infrastructure to ensure flexibility, stability, and reliability.
To achieve this, we need long-term storage systems that are holistically designed in structure, functionality, and philosophy – solving problems without creating new ones. We need a technological game changer that integrates resources, environmental impact, supply chains, and social justice into the formula for a sustainable energy future.
Our thermo-gravitational energy-storage system has the potential to boost the energy transition and foster independence – offering crucial advantages for end users, industry, and governments.
Only through the interplay of economy, ecology, and social consciousness can many people benefit sustainably from advanced technologies. That’s the kind of future-ready action we make possible with our storage technology.
We empower people to shape their future autonomously.
