Description:

Abstract: The road to sustainability is paved with electrochemical
technology. Whether it be the problem of intermittency in the generation of
electricity by renewable sources such as wind or solar or the problem of the
carbon intensity associated with metals production, e.g., iron making in the
blast furnace and aluminium smelting in the Hall-Héroult cell,
electrochemical technologies can enable radical innovation in concert with
sustainable development.

Examples of applied electrochemistry in action will be illustrated in two
different settings: 1. metals production by molten oxide electrolysis (MOE),
which is the electrolytic decomposition of a metal oxide into molten metal
and oxygen gas. MOE represents an environmentally sound alternative to
today's carbon-intensive thermochemical metals reduction processes and can
be used not only for primary metals production but also remediation of
hazardous waste; 2. stationary batteries for storage and delivery of
off-peak power. Here the emphasis is on colossal current capability, e.g.,
100s of kA with a footprint measuring 10s of metres, long service lifetime,
and very low cost. Such large format batteries are the key enabling
technology for carbon-free renewable, but intermittent, electric power
generation, while enhancing security of today's electricity grid.
Electrochemistry in nonaqueous media is the common feature in both examples.
