Water And Cooling Synergy

Because direct energy conversion removes the steam cycle, a MetroVolt plant uses very little water — a decisive advantage where data centers already strain local supply.

Two water problems, one avoided

A data center campus faces two water draws: cooling the servers, and the far larger draw at the power plants that supply its electricity through evaporative steam-cycle cooling. Co-locating a nearly waterless source removes the second draw entirely, leaving only the on-site cooling to manage.

The burner is nearly waterless because direct energy conversion turns charged-particle energy straight into electricity instead of boiling water to spin a turbine. With no steam cycle, there is no large evaporative heat-rejection load, so the plant does not compete with the campus — or the surrounding community — for a scarce cold sink. The MetroVolt water story is covered in depth in the water pages of this microsite.

This synergy is what makes urban and water-stressed siting realistic. A conventional thermal plant beside a dense campus would need a river or large cooling infrastructure; a nearly waterless burner can sit where water is precious. It also removes a weather-linked derate, since the plant does not lose output when cooling water is scarce or warm.

The honest scope: the burner removes the power-plant water draw, not the server-cooling draw. The campus still cools its own compute, but it no longer imports the much larger hidden water burden embedded in steam-generated electricity.

• Data centers draw water on-site and at their power plants
• DEC removes the steam cycle, so the plant is nearly waterless
• Enables urban and water-stressed siting
• Removes cooling-water-linked output derates; server cooling still applies
