Our solution portfolio

Five energy domains.
One integrated solution.

From power generation to heating and cooling – seamlessly integrated, scalable and ready to deploy.

Syngas

Syngas from green hydrogen and CO₂ – the basis for synthetic fuels, methanol and industrial processes.

Power

Decentralized power generation right at the point of use. Independent of grid prices and bottlenecks.

Heat

Combined heat and power up to 90% efficiency – including district heat, process heat and waste-heat recovery.

Cooling

Highly efficient cooling systems for data centers, the food industry and air conditioning.

Hydrogen

Green hydrogen as an energy carrier and industrial feedstock – production, storage, distribution.

System capability

Baseload & peak load
from one system

Not just continuous supply, but also the reserve for the moment when more is suddenly needed.

24/7

Baseload capability

Predictable, continuous energy supply around the clock – without volatility, without weather dependency. The system delivers constant baseload regardless of sun, wind or time of day, replacing fossil baseload power plants directly on site.

Milliseconds

Peak load capability

Additional capacity available exactly when demand rises short-term – without supply gaps, without costly external reserve capacity. This absorbs load peaks before they lead to bottlenecks or extra costs.

The technology solution

The technology
that makes it possible

21.Energy relies on the system technology of our technology partner – one of the most advanced providers of decentralized energy systems in the German-speaking region.

The technology solution combines all five energy forms in the smallest possible space – grid-independent, low-maintenance and scalable from small commercial operations to large industrial plants.

For sites that need affordable security of supply without sacrificing economic efficiency.
