Fundamentals of Combustion Safety Scenarios for Hydrogen

Hydrogen is a powerful energy vector but its deployment at the scale considered today by governments and companies cannot be achieved if safety associated to combustion hazards is not mastered and regulated. Hydrogen leaks occur and lead to fires and explosions which must be prevented.

To do this, regulations are needed but these regulations are based today on an incomplete understanding of the fundamental mechanisms controlling the combustion of hydrogen in air or have to consider new usages of hydrogen such as transportation (aircraft, trains, cars).

SAFE-H2 combines theory, high-precision experiments and simulations to provide reliable knowledge on the ignition, propagation, acceleration, mitigation of hydrogen-air flames in three canonical cases: flames stabilized on a hole, flames interacting with a wall, explosions in closed vessels. The proposal gathers (1) IMFT where two experimental sites, dedicated to hydrogen, will be used for low (
