According to a new study by the Centre for Sustainable Chemical Technology at the University of Bath, a more sustainable use of sunlight to make hydrogen fuel from water is one step closer.
as global leaders put pressure to reduce carbon emissions to address climate change emergencies, there is an urgent need to develop cleaner energy alternatives to burn fossil fuels. Hydrogen is a zero-carbon fuel alternative that can be used to power cars and produce only water as
.
it can be made by breaking water down into hydrogen and oxygen, but the process requires a lot of electricity. Most electricity is made from burning methane, so researchers at the University of Bath are developing new solar cells that use light energy directly to break down water.
are cheaper to build calcium-titanium solar cells
most of the solar cells on the market today are made of silicon, but they are expensive to manufacture and require a lot of very pure silicon. They are also heavy, which limits their application. Calcium-titanium solar cells using materials with the same 3D structure as calcium-titanium oxides are less expensive to manufacture, thinner and can be easily printed on the surface. They can also operate in low-light conditions and can generate higher voltages than silicon batteries, which means they can be used indoors to power devices without having to plug in a power supply.
disadvantages are that they are unstable in water, which is a huge obstacle to their development and limits their use for the direct generation of clean hydrogen fuels. A team of scientists and chemical engineers from the Centre for Sustainable Chemical Technology at the University of Bath solved this problem by using a graphite waterproof coating.
-coated cells work underwater for 30 hours
they test water resistance by immersing coated calcium-titanium batteries in water and using harvested solar energy to break it down into hydrogen and oxygen. Coated cells work underwater for 30 hours - 10 hours longer than previously recorded. After this, the glue clamped to the cell fails; Scientists predict that using stronger glue will stabilize cells for longer.
