Scientists developing clean energy systems from micro-algae

An international consortium established by an Australian scientist is developing a clean source of energy that could see some of our future fuel and possibly water needs being generated by solar-powered bio-reactors and micro-algae while absorbing CO₂.

Associate Professor Ben Hankamer, from the Institute for Molecular Bioscience (IMB) at The University of Queensland, has established the Solar Bio-fuels Consortium which is engineering green algal cells and advanced bio-reactor systems to produce bio-fuels such as hydrogen in a CO₂-neutral process.

One major advantage, especially in drought-stricken countries like Australia, is that hydrogen can be produced from salt water. Marine and salt-tolerant algae can extract hydrogen and oxygen from seawater and on combustion these gases produce fresh water and electricity, which can be fed into the national grid. Consequently, clean energy production can theoretically be coupled with desalination.
