| Abstract Scope |
A sustainable energy future is axiomatically an electric future whose realization depends in part upon electrochemical innovations. Two examples: stationary energy storage and carbon-free steelmaking. Grid-scale electricity storage not only treats the intermittency of renewable electric power generation (wind and solar) but also confers resilience to today’s grid. For example, the liquid metal battery provides colossal power capability on demand and long service lifetime at requisite low cost. In 2019, worldwide steel production, 1.869 billion tonnes, generated 9% of total anthropogenic CO2 emissions. As an example of novel approaches in this sector, molten oxide electrolysis represents an environmentally sound alternative to today’s carbon-intensive thermochemical process which produces an average 1.83 tonnes CO2 per tonne of steel. In the narratives of both of these emerging technologies, there are lessons more broadly applicable to innovation: pose the right question, engage young minds (not experts), establish a creative culture, and invent inventors. |
