"The world will run out of oil in 2030, and other fossil fuels in
2050." In the 1950s, a geologist named M. King Hubbert looked at
oil production data from all of the major oil-producing countries
in the world (at that time). Focus on the difference between the
supply and quantity supplied and demand and the quantity
demanded.
Hydrogen gas is used as a fuel instead of fossil fuels. Storage
of hydrogen is a challenge. One avenue of research involves
chemical storage such as incorporating hydrogen as part of a metal
hydride. In the following reaction sodium borohydride, NaBH4, is
used as a means for storing and later generating the hydrogen gas
in situ where it is needed as a fuel. Application of heat and use
of a catalyst drives the reaction forward. NaBH4(s) + 2 H2O(l) →...
