New technologies for decentralized energy supply

Energy supply is increasingly being organized in a decentralized manner – through photovoltaic systems, battery storage, heat pumps, and digital control systems. Providers such as Solarland Bayern, Svea Solar, and PREFA are demonstrating how residential and commercial units can be made independent of the traditional power grid. Modular energy storage solutions from companies such as Sonnen, VARTA, and TESVOLT also enable the flexible use of renewable sources.

Photovoltaic systems with storage and dynamic electricity tariffs (e.g., LichtBlick)
Plug-and-play balcony power plants for rental apartments (e.g., Green Solar)
Hybrid solutions with PV, storage, and charging infrastructure (e.g., SolaX, Smart Solar)

Decentralized systems enable greater self-sufficiency, increase energy efficiency, and create new options for self-consumption and feed-in.

Hydrogen, fuel cells, and industrial applications

Hydrogen technology is considered one of the key components for a climate-neutral future—not only in transportation, but also in industry and energy production. Companies such as Cellcentric, EKPO Fuel Cell Technologies, Siemens, and Neuman & Esser are working on scalable solutions for electrolysis, storage, and utilization. Logistics also benefits: fuel cells are replacing batteries in forklifts, fleets, and container terminals.

H2 production plants and electrolysers for industrial projects (e.g., Thyssenkrupp, Fraunhofer ISE)
System solutions for long-distance transport and commercial vehicles (e.g., Mercedes-Benz GenH2 Truck)
Specialized components such as MEAs, bipolar plates, and safety valves

The diversity of applications shows that hydrogen technology has long since arrived in operational use—no longer just a pilot project, but part of industrial strategy.

Heating solutions between heat pumps, biomass, and system integration

In the building sector, heating systems are continuing to develop in the direction of efficiency, modularity, and sustainability. Manufacturers such as Bosch, Panasonic, Solarfocus, and Weishaupt are focusing on modern heat pumps, supplemented by smart control, energy management, and combinations with photovoltaics. At the same time, biomass remains a stable component of regional heating strategies, for example through suppliers such as Hargassner and Fröling. Innovative concepts are created through:

Modular building technology with integrated ventilation (e.g., Smart Cube 360)
System solutions for hot water, storage, and heating circuit control
Planning software for heat pumps and heating systems (e.g., autarc, Zenesis)

Today, energy efficiency is no longer achieved through individual devices, but through networked systems—tailored to buildings, user behavior, and subsidy models.
