Geothermal developments across the Globe

While deep geothermal exploration is slowly taking flight in Europe, this source of durable energy has been exploited in other energy markets for a long time now. Especially the countries in the Pacific ‘Ring of Fire’ are prospective due to their high geothermal gradient and have large operational geothermal systems. For example, Indonesia alone has an approximate total geothermal capacity of about 4000 MW currently installed (sources: Islandsbanki, IGA). Major players like Chevron and TAS Energy operate the majority of this capacity in Indonesia; Chevron accounts for about 1100 MW. Yet the 4000 MW is about 10 percent of the estimated total available capacity and only 2 percent of the national energy production.

Scotland and the Philippines have recently brought forward the ambition to have their national energy production be 100 percent made from renewables. The Philippines are part of the ‘Ring of Fire’ and like Indonesia they have a large total geothermal capacity. Already 17 percent of the national energy production is of geothermal nature. In a country like Scotland, the challenges to make geothermal energy the prime renewable in the national energy budget are larger since the thermal water has to come from deep. But geothermal systems in Germany, France and the Netherlands have shown that deep geothermal energy is technically possible and capable of contributing significantly to the renewable energy budget. T&A  has brought about a system in the west of the Netherlands at 3 km deep, producing a steady 10 MW for the nearby greenhouse sector.

Even if a country is not surrounded by a ‘Ring of Fire’, geothermal energy can be traced, appraised and exploited from greater depth. The potential producible energy is vast and experience in European countries has shown that geothermal energy is a serious candidate for achieving the renewable energy targets.
