INDEX

Geothermal system linked to grid projects, has increased output at a Nevada geothermal plant with the first commercial use of technology developed to tap underground energy sources that would be inaccessible using traditional systems. Ormat Technologies Inc, a US developer of renewable power

Ormat increased the capacity of its Desert Peak 2 facility in Nevada by about 38 percent, or 1.7megawatts, according to a statement from the US energy department. In enhanced geothermal systems, water is injected into the ground, either at aging power plants where the steam resource has been depleted or at sites where there are hot rocks and no steam. Once heated, the water is piped back to the surface to make power. Desert Peak is the first commercial plant connected to the US power grid to use enhanced geothermal systems. The US Geological Survey estimates the technology may eventually enable the development of as much as 500GW of capacity in the country.
