—During the past decade, major studies have
identified hydrogen as the safest fuel and its demand has been
on the rise ever since. This paper looks into the different
biological methods of hydrogen production and the economics
involved in-order to identify the most economical and
environment friendly method of biohydrogen production. A
detailed study has been conducted regarding the methods of
production, the types of reactors and raw-materials required.
The cost requirement of each of the aspects involved in the
processes have been looked into. The study proves the Direct
Biophotolysis method to be the least favourable in-terms of land
requirement and costs and Indirect Biophotolysis and
Photofermentation to be amongst the better options available.
