Hydrogen Production. Green Algae as a Source of Energy

TLDR

Hydrogen is considered an ideal, environmentally sustainable fuel that could pair with electricity to power transportation and generate electricity on-site, but large‑scale, renewable production remains a challenge. The study aims to encourage, test for feasibility, and advance laboratory‑stage processes toward commercial hydrogen production. The authors propose to evaluate and promote laboratory‑stage hydrogen production processes, assessing feasibility and guiding them toward commercialization.

Abstract

Hydrogen gas is thought to be the ideal fuel for a world in which air pollution has been alleviated, global warming has been arrested, and the environment has been protected in an economically sustainable manner. Hydrogen and electricity could team to provide attractive options in transportation and power generation. Interconversion between these two forms of energy suggests on-site utilization of hydrogen to generate electricity, with the electrical power grid serving in energy transportation, distribution utilization, and hydrogen regeneration as needed. A challenging problem in establishing H(2) as a source of energy for the future is the renewable and environmentally friendly generation of large quantities of H(2) gas. Thus, processes that are presently conceptual in nature, or at a developmental stage in the laboratory, need to be encouraged, tested for feasibility, and otherwise applied toward commercialization.
