Salt Water System Could Generate Hydrogen

(PhysOrg.com) -- The idea of generating hydrogen from salt water has often been claimed to work effectively. However, the systems proposed so far generally require a much greater energy input than the energy they produce, ...

Scientists unlock the secrets of a sixth basic flavor

Japanese scientist Kikunae Ikeda first proposed umami as a basic taste—in addition to sweet, sour, salty and bitter—in the early 1900s. About eight decades later, the scientific community officially agreed with him.

Chemical engineers borrow technique to store solar energy

(Phys.org) —Chemical engineers at Stanford have designed a catalyst that could help produce vast quantities of pure hydrogen through electrolysis – the process of passing electricity through water to break hydrogen loose ...

A step closer to sustainable energy from seawater

The research group led by Leiden chemist Marc Koper has discovered a catalyst that minimizes the production of chlorine gas during salt water electrolysis. The invention can enable the direct production of hydrogen from seawater. ...

Germany rolls out world's first hydrogen train

Germany on Monday rolled out the world's first hydrogen-powered train, signalling the start of a push to challenge the might of polluting diesel trains with costlier but more eco-friendly technology.
