The team showed that the device could run efficiently for 12 consecutive days and produced hydrogen with 99 percent purity.
A team of researchers have produced a novel molecule that could be used to allow hydrogen to be made from solar energy on demand—even when the Sun is not out.
Orbital Marine Power O2 tidal turbine will be able to single-handedly generate enough clean-power to supply 2,000 UK homes, offsetting 2,200 tonnes of CO2 a year.
Researchers have developed a generator that uses a field-effect transistor-style structure to instantly produce a surprisingly high voltage from water drops - a single drop can muster 140V, or enough power to briefly light up 100 small LED bulbs.
According to statistics, hydropower accounts for the largest share with an installed capacity of 1,172 GW, wind and solar energy account for most of the remainder with capacities of 564 GW and 480 GW respectively.
It's challenging to electrify aviation using batteries or fuel cells in part because of the weight restrictions on aircraft, so liquid biofuels have the potential to play a big role in greenhouse gas emissions reductions.
UK startup Orbex has showed off its Prime Rocket's second stage. Inside the engineering prototype's shell is the "world's largest" 3D printed rocket engine, which is also designed to run on bio-propane, a renewable fuel source.
Etihad Airways has become the world's first airline to fly a commercial flight using locally produced sustainable fuel derived from plants grown in saltwater.
Spain’s state-owned chain of grand hotels often housed in ancient castles and monasteries, has announced that all 97 of its establishments will use only electricity from renewable sources from the start of the new year.
