Technical barriers for harnessing the green hydrogen: A power system perspective.

Extracting green hydrogen from renewable energy sources is a new concept in the energy industry. As an energy carrier, hydrogen is well capable of facilitating a strong coupling between various energy sectors, as well as integration of renewable energy sources. This paper investigates the system-wide technical factors that might limit the amount of producible hydrogen in a given power system. A non-linear programming formulation is proposed to quantify the impact of voltage security constraints, the location and size of power to hydrogen facilities, and finally the wind penetration levels on the harvest-able green hydrogen. The applicability of the proposed framework is demonstrated on the IEEE 39 bus system. • The clean green hydrogen is a game changing factor in energy industry. • The total producible green hydrogen should be calculated considering OPF. • Harness-able green hydrogen decreases in higher levels of voltage stability margins. • The power transmission system constraints influence the green hydrogen production. • Large Power-to-Hydrogen units can control the wind curtailment.
