Going far above and beyond its original mission objectives, results from the GOCE gravity satellite are now being used to produce maps for geothermal energy development.<\/span><\/p>\n

Geothermal energy is heat from under Earth\u2019s surface. From hot springs to magma, this energy provides a clean, sustainable resource that can be used to generate electricity, heat buildings, grow plants in greenhouses and many other applications.<\/span><\/p>\n

These energy sites exist underground, but often in remote areas, making them difficult, expensive and time-consuming to explore and measure. While the potential of geothermal energy worldwide remains vast, more effort is needed to develop and harness it.<\/span><\/p>\n

To help facilitate their exploitation, scientists from ESA and the International Renewable Energy Agency (IRENA) have used gravity measurements from the GOCE mission to produce an\u00a0online tool<\/span><\/a>\u00a0that indicates areas likely to possess geothermal potential, narrowing the search for prospectors.<\/span><\/p>\n

The tool\u2019s maps show\u00a0certain characteristics that may help in the search for geothermal reservoirs, including areas with thin crusts, subduction zones and young magmatic activity.<\/span><\/p>\n

\u201cThese maps can help make a strong business case for geothermal development where none existed before,\u201d said Henning Wuester, Director of IRENA\u2019s Knowledge, Policy and Finance Centre.<\/span><\/p>\n

\u201cIn doing so, the tool provides a shortcut for lengthy and costly explorations and unlocks the potential of geothermal energy as a reliable and clean contribution to the world\u2019s energy mix.\u201d<\/span><\/p>\n

After a potential site location has been selected using the online tool, ground surveys and seismic measurements are still needed to determine the exact points for energy extraction, but the new resource is a step towards developing a comprehensive geothermal prospecting technique.<\/span><\/p>\n

The maps outline two specific global gravity anomalies: \u2018Bouguer\u2019 and \u2018free air\u2019.<\/span><\/p>\n

The free air gravity map provides information on geological structures, while the Bouguer gravity anomaly map combines GOCE data with information of global topography to show differences in crustal thickness. Together, the maps depict characteristics unique to geothermal reservoirs.The two maps are complementary and form a basis to discriminate and classify different terrains at a country-wide scale.GOCE\u2019s mission ended in October 2013 when it ran out of fuel and subsequently reentered Earth\u2019s atmosphere. But its wealth of data continues to be exploited to improve our understanding of ocean circulation, sea level, ice dynamics and Earth\u2019s interior.\u201cThis is the first time that global gravity data from GOCE have been used as a tool for geothermal energy site exploration,\u201d said Volker Liebig, Director of ESA\u2019s Earth Observation Programmes.\u201cESA will continue its collaboration with IRENA to further improve space-based gravity data as a resource for sustainable energy development.\u201d<\/span><\/div>\n
