Fuel cell developments: drones and navy.

Hydrogen technology is continuously evolving. Although we are still a bit far away from having a fuel cell in our house to supply energy, we are much closer than some years ago. Hydrogen developments aren’t limited to buildings. Many times, we can find outstanding discoveries in other fields such as automotive or smartphones. Today, we want to show you two amazing developments carried out in drones industry and navy. Because, maybe, we aren’t so far away from a hydrogen society.

Fuel cell on the air: a drone

One of the main drawbacks of current drones is its limited battery. They run out of energy really quickly and require to be charged for a long time before flying again. Cella, a company specialized in developing hydrogen storage solutions, has developed a type of pellets that release hydrogen when heat is applied. One of the main problems of hydrogen storage is the necessity of high-pressure tanks. But this has been solved thanks to Cella’s pellets.

The solution is much lighter than a common Li-ion battery and can last up to 2 hours. The pellets don’t require a high pressure and are solid under 500ºC. When heated up, they released a great amount of hydrogen that is converted into energy thanks to a fuel cell.

Fuel cell from the air: a Boeing’s development

Everybody knows Boeing. Yes, the airplanes manufacturer. But you may be suprised if we tell you that they also develop solutions for energy storage. The latest one is based on hydrogen fuel cell. Nevertheless, it isn’t a ‘common’ hydrogen facility. The system used for this development is known as “reversible solid oxide fuel cell”.

The most interesting and promising feature is that it can both store and generate energy. You can connect it to a solar or geothermal facility and stock the extra energy produced by generating, compressing and storing hydrogen. Afterwards, when that energy is required, it operates as a fuel cell. The great innovation of the system is that it can store and generate energy within the same solution. Nowadays, the equipment is being tested by the US Navy.
