## Title

A new 62L 70MPa H2 CPV: from conception to first flight

## Abstract

In the context of low-carbon mobility using gaseous di-hydrogen, such as light vehicles, trucks, trains, buses, boats, motorcycles with fuel cell or combustion engine, it is necessary to store a maximum of di-hydrogen to obtain the greatest possible autonomy. For this, type IV composite pressure vessels operating at 70MPa best meet user objectives.

The Atomic Energy and Alternative Energies Commission (CEA) has joined forces with the Wroclaw University of Technology (WUT) and the industrial company RAIGI to design, manufacture and test a 62L tank capable of storing 2.5 kg in a space 880 mm long and 400 mm in diameter. The use of two 62L tanks guarantees a minimum of 500 km for a light vehicle with a filling time of around 5 minutes.

Taking into account the integration constraints, transversely to the axis of a light vehicle, the CEA's work on the definition of the tank (composite, boss, liner) made it possible [1], thanks to numerical optimization using finite elements [2] and use of a CEA's FIWIQUS plugin for Abaqus to simulate the deposition of each composite layer by filament winding.

The CEA transferred its manufacturing technology to the industrial company RAIGI. Following that, the tank was manufactured by RAIGI while verifying that the manufactured
object corresponded to the definition. Numerous tanks have been manufactured to carry out
all the tests, including the tests required by regulations.

The Wroclaw University of Technology then carried out all the hydraulic tests required by
European regulation EC79 in order to be able to certify the tanks [3]. The first tests were burst
tests followed by cycling tests at room temperature (15,000 cycles) then cycling tests at
extreme temperatures (7,500 cycles at +85°C and 7,500 cycles at -40°C). Following tests were
also carried out: creep, chemicals, flaws, leaks, falls, proof. Additional hydrogen cycling tests
were also carried out.

The tank was then integrated into an aircraft to achieve the first fully hydrogen flight.
