Germany Develops New Hydrogen Tank Filament Winding Production Process System
Institut fuer Verbundwerkstoffe GmbH, or IVB, has developed a new hydrogen tank filament winding production process system that will allow Germany to produce hydrogen tanks in record time. According to the company, the new process will save up to 50 percent of the time spent on filament winding. This process will also make hydrogen tanks and Carbon Fiber Speargun more durable, and can reduce production costs.

Increasing demand for renewable energy sources is driving the growth in the hydrogen economy. High-pressure storage of compressed hydrogen is required for applications in the automotive industry.
The demand for hydrogen as well as CFRP Sheet is expected to increase 16.6% over the next five years. However, hydrogen can also be stored in gaseous form, which is important for future sustainable mobility. Moreover, the storage capacity of pressure vessels is a major challenge.
The German company Institut fuer Verbundwerkstoffe has developed an expanded system technology for wet winding of hydrogen tank systems. This equipment is designed for higher production rates and superior efficiency. It can also produce lightweight fiber-reinforced pressure vessels.
The StorHy project (StorHy means hydrogen) aims at developing hydrogen storage systems for use in the automotive industry. Its aim is to improve the performance and consistency of 300+ litre hydrogen tanks.
The new system is based on an industrial winding machine and a robotic laying head. It is equipped with an automatic pressure measuring system and a roving cutting and applying device.

Institut fuer Verbundwerkstoffe GmbH (IFVW) in Germany has developed a new hydrogen tank filament winding production process system, which has the potential to improve material throughput by three times. The system is based on a 6-axis industrial robot carrying a fiber laying head. It has been successfully tested on an endurance test, in which it worked without failure for an eight-hour shift.
The system has been designed to allow the deposition of the fiber band as orthogonal to the winding core as possible. This allows the laying head to be swiveled, as well as to increase the speed of the winding machine. The swivel angle is controlled by the winding machine's CNC control. The laying head is equipped with a 24-mm wide groove to limit the maximum fiber bandwidth at the end of the laying head.
In order to determine the absolute fiber bandwidth, it is necessary to take into account the effects of fiber spreading, as well as the processing parameters that affect the bandwidth. For a circumferential winding, the bandwidth is generally larger, as the band is deposited in a larger area than in the cylindrical area.
Liquid hydrogen tank project fuels UK zero-carbon aviation ambitions
Developing the technology for liquid hydrogen powered aircraft is one of the key objectives of the UK Government's FlyZero project. The project has been developed by a team of aerospace experts and seeks to reduce the carbon footprint of commercial air travel.
The UK is aiming to demonstrate technology for zero-carbon aircraft by 2025. A new generation of aircraft is expected to be in service by 2035. This presents a unique opportunity to integrate sustainability into the design of these aircraft. It will also present opportunities to enhance reuse of materials.
Hydrogen is a low odourless gas that can be used for vehicles, transport and aviation. It is considered the front runner to replace conventional fossil fuels. However, it is not sufficient for long-haul flights. For this reason, the commercial aviation industry needs to adapt its fuel to meet the demands of the market.
The Aerospace Technology Institute, a UK government-backed organization, is conducting research into the use of green liquid hydrogen for short-haul flights. This research demonstrates the potential of liquid hydrogen in global connectivity.
Type IV hydrogen tanks
Increasing demand for hydrogen economy is driving the development of tank technologies for gas transport and Carbon Fiber Flag Pole. In particular, hydrogen for FCEV is typically stored in type IV composite pressure vessels. The high pressure and lightness of these containers make them attractive for numerous mobility applications. However, the cost of these tanks is a major challenge for the growth of the hydrogen tank industry.
In order to reduce the cost of type IV hydrogen tanks, new manufacturing technology is being developed. The cost of the carbon fibers used to manufacture the high pressure vessels is 50% of the total cost of the storage system. Therefore, effective pressure vessel manufacturing processes are essential.
The German firm Mikrosam and the Netherlands-based firm H2Storage have collaborated on developing a new filament winding production process for hydrogen pressure vessels. The result is a new system that allows for three times more material throughput than conventional winding systems. The system uses a new ring winding head that is an extension for a conventional filament winding machine. It connects the CNC control of the winding machine to a Windows-based industrial PC.
