While energy sources such as wind and solar are great at producing emissions-free electricity, they depend on the sun and the wind, so supply doesn't always meet the demand. Likewise, nuclear power plants operate more efficiently at maximum capacity so that electricity generation can't be easily ramped up or down to match demand.

For decades, energy researchers have tried to solve one big challenge: How do you store excess electricity so it can be released back onto the grid when it's needed?

Recently, researchers at Idaho National Laboratory helped answer that challenge by developing a new electrode material for an electrochemical cell that can efficiently convert excess electricity and water into hydrogen. When demand for electricity increases, the electrochemical cell is reversible, converting hydrogen back into electricity for the grid. The hydrogen could also be used as fuel for heat, vehicles or other applications.

The results appeared online this week in the journal Nature Communications.
