Absorbing extraction

Filters can rid water of pollutants directly at the source. Now, an LA-based startup is aiming to remove CO2 from seawater. Why? The world’s oceans store around 30% of annual CO2 emissions and can absorb 150 times more of the gas than air. But as coral death shows, the situation is far from ideal. The new process sees carbon...

Absorbed separation

Plant secretions are a useful source of energy. Inspired by photosynthesis, a research team from Lausanne has developed leaf-like electrodes which, powered by solar energy, can generate hydrogen from air humidity. The basis for the technology is a thin, light-transmissive and porous mesh made from melted quartz fibres. After being coated with fluorine-doped tin oxide, the structure becomes highly...

Speedy provision

Water with plant-based surfactants can contain smouldering fires faster. Now, a Michigan-based startup has developed a mobile solution to supply electricity quickly during outages caused by natural disasters. Their trailer is equipped with solar panels, a battery for storing electricity and a fuel cell powered by sustainable hydrogen. Thanks to augmented reality training, anyone can operate the system within...

Accelerating addition

Waste heat from houses or hot water pipes can be converted into electricity. Fermenting food waste is already used to produce hydrogen. Now, an American research team has accelerated the process by adding yeast. Their patented method can produce hydrogen as a clean fuel source within 18-24 hours instead of the usual several days, while also eliminating the risk...

Offline conversion

Banana and orange peel can be made into hydrogen and biochar in the blink of an eye. Now, thanks to an Irish startup’s innovation, organic food waste can be turned into biogas and liquid fertiliser in backyards or on company grounds. Come rain or shine. Waste is mixed with water and put through the system’s macerator. The resulting pulp...

Sustainable impuls

We’ve seen football jerseys from coffee grounds and electricity from oranges. Now, a Swiss research team is turning leftover fruit and vegetables into hydrogen and biochar in a flash. First banana- and orange peel, corn cobs or coffee beans are dried and ground. Next the resulting powder is heated and evaporated with a high energy Xenon flash lamp. The...
