"The economic and environmental gains identified in this research are simply too significant to leave unrealized and will only be more enticing as this decade proceeds and the next dawns and costs of renewable energy and electrolyzers continue to fall and advanced control systems and energy management continue to advance in unimagineable ways."
- Dr. Thomas Alan Kwan, Vice President Sustainability Research, Schneider Electric
01
Cost Advantage
Semi-islanded energy systems achieve 12-15% lower levelized cost of steel (LCOS) at $781-811/ton compared to grid-only alternatives ($887-929/ton).
02
Emissions Reduction
These optimized hybrid systems can enable emissions reductions of 46-84% compared to conventional steelmaking routes.
03
Lifecycle Economics
While requiring 60-84% higher upfront investment than grid-only systems, semi-islanded configurations deliver superior lifecycle economics through operational cost reductions.
04
Preferred Storage
Hydrogen is consistently the preferred energy storage medium over batteries in most optimization scenarios due to its dual role as a process input and energy buffer.
05
Volatility Opportunity
Increased grid price volatility paradoxically lowers overall production costs for semi-islanded systems by enabling strategic purchase of cheap grid power.
06
Renewable Mix
Solar energy is the preferred renewable source in baseline scenarios, with wind power integration increasing strategically as grid electricity costs rise.
