Hydrogen Has The Potential To Revolutionize Electric Mobility, But Still Faces Significant Hurdles. An Austrian Company Promises To Change The Game With A New Storage Technology.
Hydrogen has gained traction as a clean alternative in electric mobility, but it still faces two major challenges: the high pressure required for storage and the limited infrastructure for refueling.
The Austrian startup HydroSolid claims to have found a solution to both problems with the development of a new hydrogen storage system.
How Hydrogen Is Stored Today
Currently, hydrogen used in vehicles is stored in a gaseous state and at extremely high pressures, typically at 700 bar. This allows for greater energy density, but requires reinforced tanks and robust safety systems.

An example is the Toyota Mirai, which has three tanks with a total capacity of 5.6 kg. The vehicle offers a range of up to 650 km and refueling in under five minutes.
These tanks can withstand pressures of up to 1,500 bar and use materials such as carbon fiber, in addition to pressure relief valves and multilayer structures.
Hydrogen distribution is done by tanker trucks or pipelines, but the refueling infrastructure is still scarce. In Spain, for example, there are only eight public stations, with a plan to reach 100 by 2030.
HydroSolid Bets On Nanopolymer To Change The Scenario
HydroSolid has created a technology called HIVE S1. The system uses a patented nanopolymer that stores hydrogen at low pressure — only 35 bar — which is a significant difference compared to traditional methods. This material adsorbs hydrogen at room temperature and releases it with mild heating, making the process simpler and safer.
Most importantly, the system offers energy density of up to 3 kWh per liter, surpassing various existing batteries. This could benefit different sectors, from vehicles to the energy industry.
Advantages Of The New System
The HIVE S1 presents several benefits. Safety is one of the main points, as the low pressure reduces risks in the storage and transportation of hydrogen. Additionally, the system is sustainable, as it does not use critical materials such as lithium, cobalt, or rare earths. The entire equipment is recyclable.
Another strong point is versatility. The modular design allows for applications on different scales, being usable in both homes and large industries. Therefore, HydroSolid’s technology could drive energy decentralization and support communities seeking self-sufficiency.
Recognition And Important Partnerships
Due to this innovation, HydroSolid was named “Startup of The Year 2022” in Austria. The company also received the “Seal of Excellence” from the European Union.
In addition, it is part of the European Space Agency’s (ESA) incubation program, which allowed for the use of space technologies in the development of HIVE S1.
HydroSolid’s proposal combines efficiency, safety, and sustainability. With this, the company offers a direct response to the obstacles that still prevent the widespread adoption of hydrogen as a clean energy source.
Muito bem…a empresa hydrosolid estão de parabéns, mas gostaria ter mais informações sobre o tipo de material reciclado foi usado para o armazenamento e qual é a temperatura permitida para o armazenamento do oxigénio
E como seria a recarga da unidade?
Espero que chegue a nós, essa descoberta com acessibilidade, para acabar com o monopólio de energia elétrica residencial.
