Answer:Desventajas del hidrógeno como fuente de energía

Una desventaja de producir este hidrógeno como fuente de energía es que su densidad es muy baja, por lo que se requieren tanques más grandes para guardar la misma cantidad de masa. Si lo comparamos, un tanque de hidrógeno necesita más espacio y más peso que uno para almacenar la misma cantidad.

El proceso de extracción se le conoce como electrólisis, que consiste en la descomposición de las moléculas de agua (H2O) en oxígeno e hidrógeno. La desventaja de esto es el elevado precio que esto conlleva pues se necesita mucha energía — no renovable en la mayoría de los casos — para alimentar los electrolizadores.

Hydrogen Energy is Expensive
Electrolysis and steam reforming, the two main processes of hydrogen extraction, are extremely expensive. This is the real reason it's not heavily used across the world. Today, hydrogen energy is chiefly used to power most hybrid vehicles.

Explanation:

Australopithecina or Hominina is a subtribe in the tribe Hominini. The members of the subtribe are generally Australopithecus (cladistically including the genera Homo, Paranthropus,[2] and Kenyanthropus), and it typically includes the earlier Ardipithecus, Orrorin, Sahelanthropus, and Graecopithecus. All these related species are now sometimes collectively termed australopithecines or homininians.[3][4] They are the extinct, close relatives of humans and, with the extant genus Homo, comprise the human clade. Members of the human clade, i.e. the Hominini after the split from the chimpanzees, are now called Hominina[5] (see Hominidae; terms "hominids" and hominins).

While none of the groups normally directly assigned to this group survived, the australopithecines do not appear to be literally extinct (in the sense of having no living descendants) as the genera Kenyanthropus, Paranthropus and Homo probably emerged as sister of a late Australopithecus species such as A. africanus and/or A. sediba.

The terms australopithecine, et al., come from a former classification as members of a distinct subfamily, the Australopithecinae.[6] Members of Australopithecus are sometimes referred to as the "gracile australopithecines", while Paranthropus are called the "robust australopithecines".[7][8]

The australopithecines occurred in the Plio-Pleistocene era and were bipedal, and they were dentally similar to humans, but with a brain size not much larger than that of modern apes, with lesser encephalization than in the genus Homo.[9] Humans (genus Homo) may have descended from australopithecine ancestors and the genera Ardipithecus, Orrorin, Sahelanthropus, and Graecopithecus are the possible ancestors of the australopithecines.[8]
