Scientists Create Living Factories That Churn Out Hydrogen Fuel - Futurism

By jam-packing photosynthetic algae into sugary droplets of water, scientists are building mini biological factories that churn out hydrogen that could be used as a source of carbon-neutral energy.

Under finely-tuned conditions inside the water droplet, the algae will stop producing oxygen and instead give off energy-packed hydrogen, according to research published Wednesday in the journal Nature Communications.

While the minuscule factories are far too small to power our homes or cars for now, the research points to a possible source of sustainable clean energy if the process scales up.
