Tata group in India to make a unit suitable for individual houses to provide electricity
with energy storage in the form of hydrogen. The hope is tomarket many small units
to villagers in rural India, providing power and mitigating, to some extent, the rapid
construction of coal burning power plants (said to be four per week in India and
China) with their known adverse effect on the climate [135].
Storage as touched on in a discussion of a planned European grid of wind power
sources is given in The Economist [136]. This article notes an advantage of linking
Norway to a proposed European wind power grid: to gain storage capacity. It is stated
that the energy storage capacity obtained by pumping water uphill into storage above
existing hydroelectric dams in Norway is suf cient to completely power the proposed
European wind power network over a period of 4 weeks. If this statement is correct,
