This is attributed to hydrogen having a higher lower heating value (LHV) compared to methane (∼120 MJ/kg compared to ∼ 50 MJ/kg), resulting in higher thermal energy release when combusted. Additionally, hydrogen is more reactive than methane which allows stable combustion at lower equivalence ratios [29], [56], [58].
