The maximum sugar yield was obtained at Coconut husk mild severity factor. This was conﬁrmed by the degradation of hemicellulose, cellulose and lignin. The tendency Subcritical water of the changing of sugar yield as a result of increasing severity factor was opposite to the tendency of pH change. Enzymatic hydrolysis It was found that CO gave a diﬀerent tendency of severity factor compared to N as the pressurizing gas. The 2 2 Fermentation result of SEM analysis conﬁrmed the structural changes during SCW pretreatment. This study integrated three steps all of which are green processes which ensured an environmentally friendly process to produce a clean biohydrogen. 1. Introduction Coconut husk
