the fuel of the future
It is well established that humanity is in the midst of experiencing a worldwide climate change, rendering the ecological systems on earth less suitable for supporting an ever-growing human population. The major underlying cause for this abrupt change in the planet’s heat balance is the anthropogenic use on fossil fuels, resulting in the emission of greenhouse gases. Finding an alternative energy source is therefore of utmost importance and constitutes one of the most pressing challenges humanity faces in the 21 century.
Gaseous Hydrogen is a promising candidate for replacing carbon-based fuels, since its utilization emits water vapor alone. While hydrogen utilization technologies are already available in mass production, gaseous hydrogen itself is a rare and expensive resource. Thus, producing hydrogen gas in a clean sustainable manner is an efficient solution for alleviating climate change.
photosynthesis is considered a promising blueprint for bio-hydrogen production. During this process, water molecules are broken down into protons and electrons by a gradual enzymatic process of oxidation, fueled by solar irradiance. These protons bear the potential of being re-synthesized into hydrogen gas. In nature, this reaction is catalyzed by hydrogenase, a special enzyme found in certain microalgae species.
