Hydrogen for Renewable-Energy Balancing

What this topic covers

Convert electricity into hydrogen when generation and demand do not align.

Core energy-system ideas

Hydrogen can provide longer-duration energy storage in some system concepts.

Electrolyzer utilization depends on electricity availability and economics.

Platinum demand arises only from the PGM-containing technologies selected.

Important tradeoffs

Platinum intensity should be compared on a consistent application basis.

Material and performance evidence

Not every fuel-cell chemistry uses platinum, so technology type matters when estimating demand.

Lifecycle perspective

End-of-life recovery opportunity grows as installed platinum-containing equipment accumulates.
