Whereas battery
storage is a relatively recent technology for large -
scale applications, ways of storing thermal energy — such as using cheap off - peak
electricity to freeze ice for daytime air conditioning — have been around for decades.
It is now well understood that universal
electricity access by 2030 (a core part of U.N. Sustainable Development Goal 7 - SDG 7) can only be achieved if decentralized renewable energy (DRE)-- green micro-grids and rooftop solar paired with
storage and ultra-efficiency appliances — gets adequate finance to reach
scale quickly.
While total output from low carbon technologies, such as hydro, wind, solar, biomass, geothermal, and nuclear power, has continued to grow, their share of global primary energy supply has remained relatively constant; fossil fuels have maintained their dominance and carbon dioxide capture and
storage (CCS) has yet to be applied to
electricity production at
scale.
With upstream uranium mining and downstream waste
storage available in one place, the intermediate steps (enrichment and nuclear power) can easily be added — creating huge vertical (i.e. the nuclear production and waste - handling chain) and horizontal (
electricity output) economies of
scale.
Meanwhile India's Central
Electricity Authority (CEA) is currently deciding whether or not to mandate that large -
scale solar and wind power plants should have some energy
storage installed onsite as standard.
But he wholly fails to explain what the implications of the variability problem is (the need for overbuild of generation capacity and expensive / unfeasible large -
scale energy
storage), nor whether, if an effort is made to deal practically with these problems in real national
electricity grids, the «increasingly cheaper» renewables will ever become cheap enough (when all relevant real - world factors are considered) and reliable enough (without natural gas «backup»), to actually substitute for and displace fossil fuels (or nuclear) at the
scale required.
