Autonomous Drone Systems

RES21 – Renewable-Energy-Solutions-Programm


Critical infrastructure facilities require regular inspections, which can be challenging in remote areas. Traditionally, expensive and polluting aircrafts have been used for inspections. Today, innovative solutions enable more cost-effective and environmentally friendly alternatives.

Ensol Systems Inc. in collaboration with Chartis Remote Sensing Solutions has developed an autonomous drone-in-a-box solution. This solution enables multiple daily inspection flights, does not require a pilot and offers multiple sensor systems.

The solution is self-contained, connected to the cloud and powered by a Remote 400 propane fuel cell and optional solar power. It enables self-charging and automatic data upload for continuous operation. The system is portable and offers cost savings, environmental benefits and long autonomy.

Remote fuel cell generators are certified according to international standards, i.a in the U.S., Canada and the EU, to ensure safety and reliability for customers.

This project is supported by the German Federal Ministry for Economic Affairs and Climate Action as part of the Renewable Energy Solutions Programme of the German Energy Solutions Initiative.


The German Energy Agency (dena) is a centre of excellence for the applied energy transition and climate protection. dena studies the challenges of building a climate-neutral society and supports the German government in achieving its energy and climate policy objectives. Since its founding in 2000, dena has worked to develop and implement solutions and bring together national and international partners from politics, industry, the scientific community and all parts of society. dena is a project enterprise and a public company owned by the German federal government. Dena’s shareholder is the Federal Republic of Germany.


With the aim of positioning German technologies and know-how worldwide, the German Energy Solutions Initiative of the Federal Ministry of Economics and Climate Action (BMWK) supports suppliers of climate-friendly energy solutions in opening up foreign markets. The focus lies on renewable energies, energy efficiency, smart grids and storage, as well as technologies such as power-to-gas and fuel cells. Aimed in particular at small and medium-sized enterprises, the German Energy Solutions Initiative supports participants through measures to prepare market entry as well as to prospect, develop and secure new markets.


With the RES programme, the Energy Export Initiative of the Federal Ministry of Economics and Climate Action (BMWK) helps German companies in the renewable energy and energy efficiency sectors enter new markets. Within the framework of the programme, reference plants are installed and marketed with the support of the German Energy Agency (dena). Information and training activities help ensure a sustainable market entry and demonstrate the quality of climate-friendly technologies made in Germany.
