Hydrogen Peroxide has been investigated and used as a propellant since the 40's.However, since the 70's there has been significant controversy regarding the storability, long term chemical compatibility and handling of the high purity grades required for the use as a propellant.
 
In the past decade, extensive research has been devoted to hydrogen peroxide including major efforts in Europe (e.g. EU FP7 GRASP). This includes a better understanding of the hydrogen peroxide chemistry but is not yet conclusive.

Propellant tanks, due to their materials and the very high area to mass ratio that make them decelerate fast during reentry, are among the elements that survive reentry. In addition, tanks are normally quite enclosed within the satellite structure making them surviving the re-entry and having a large on-ground footprint. Therefore, the development of demisable tanks is considered of the highest priority by the LSIs for their uncontrolled re-entry LEO platftorms.

Iodine has been recognised as interesting propellant for electric propulsion applications since it allows to significantly reduce the cost and complexity of the propulsion system due to the fact that it is solid at room temperature and sublimates directly to gas at moderate temperatures. While iodine propellant has many advantages, there are also some challenges to overcome due to the fact that iodine is highly reactive.

The activities executed within the project NoTank - NOvel composite propulsion TANK architecture for small satellites aimed at maximising space use for the propulsion system in Smallsats, by improving the space efficiency of the propellant storage tank. Compared to conventional propulsion tank systems, the solution has the potential to reduce the overall cost of the satellite and provide a modular design that can adapt to various spatial configurations.

The life span of space craft in orbit is mainly limited by the amount of available fuel for attitude control and repositioning tasks. The possibility to refuel a satellite after some years in orbit could therefore extend the duration and thereby lower the costs of space craft operation, significantly.
