New nanomaterial can extract hydrogen fuel from seawater

It's possible to produce hydrogen to power fuel cells by extracting the gas from seawater, but the electricity required to do it makes the process costly. UCF researcher Yang Yang has come up with a new hybrid nanomaterial ...

New catalyst efficiently produces hydrogen from seawater

Seawater is one of the most abundant resources on earth, offering promise both as a source of hydrogen—desirable as a source of clean energy—and of drinking water in arid climates. But even as water-splitting technologies ...

New eco-battery that runs on seawater

Researchers at Ulsan National Institute of Science and Technology (UNIST) in South Korea will be working to develop a new battery, using abundant and readily available seawater.

Cheap hydrogen fuel from seawater may be a step closer

(PhysOrg.com) -- A new catalyst has been developed to generate hydrogen from water cheaply, but the research was originally intended to make molecules that behaved like magnets. Hydrogen is a clean power source currently ...

Seawater

Seawater is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5%. This means that every 1 kg of seawater has approximately 35 grams of dissolved salts (mostly, but not entirely, the ions of sodium chloride: Na+, Cl-). The average density of seawater at the surface of the ocean is 1.025 g/ml; seawater is denser than freshwater (which reaches a maximum density of 1.000 g/ml at a temperature of 4°C) because of the added mass of the salts. The freezing point of sea water decreases with increasing salinity and is about -2°C (28.4°F) at 35 gram per liter.
