EGS, AGS, and Supercritical Geothermal Systems: What’s the Difference?

EGS, AGS, and Supercritical Geothermal Systems: What’s the Difference?

The spectrum of geothermal technologies is quickly evolving. This supplement to POWER’s April 2023 feature, “Startups Are Shaking Up Geothermal Power’s Potential,” briefly explains the differences between some engineered geothermal systems. Conventional geothermal energy is largely produced by hydrothermal systems, which consist of hot water circulated in deep-seated permeable rocks. Resource temperature ranges from high (greater than 150C), medium (90–150C), and low (less than 90C). Geothermal […]

The Tremendous Potential—and Challenge—of Offshore Wind Energy

The Tremendous Potential—and Challenge—of Offshore Wind Energy

Wind turbines must move farther offshore to gain greater efficiency. But the challenges associated with doing so are significant. At the Dutch village of Den Oever, just north of Amsterdam, the A7 motorway extends onto the Afsluitdijk, a 32-kilometer dike that separates IJsselmeer Lake and the North Sea. Near the midway point, approaching the village of Breezanddijk, a veritable forest of near-shore wind turbines emerges […]
