Researchers at KAUST have developed and used a novel way of increasing the chemical reactivity of a two-dimensional molybdenum disulfide material to produce a cheap and effective catalyst for water splitting to produce hydrogen. A monolayer of molybdenum disulfide is only reactive for reducing water to hydrogen at its edge.

You need large auxiliary systems to remove the carbon dioxide and water, and it’s very hard to do this.” Overall, the new battery system is “ very scalable, cheap, and much safer ” than lithium-air batteries, Li says. But the new battery, which never needs to draw in any outside air, circumvents this issue. 2016.111.

Replacing conventional high-pressure hydrogenation by direct ECH promoted a seamless flow between the processes, allowing the use of the broth water, salts, and impurities as electrolyte and hydrogen source.

Companies have looked into pumped hydroelectric systems that generate electricity from water flowing out of large artificial reservoirs, underground caverns that store hydrogen fuel electrolyzed from water, elevators that lift blocks of concrete and harvest their potential energy as they fall. But the space is still young.

The European Union (EU) market, which is home to about 30% of algae activity, will be limited initially by the industry’s focus on university research, and later by insufficient access to water, land, and nutrient sources. Ultimately, algae potential is greatest in regions where there is an abundance of land, water, and sunlight.
