據今日油價10月11日報道，在能源轉型加速的推動下，隨著能源公司多元化市場發展，預計地熱額定容量將在未來5年內擴大。Rystad能源公司的一份分析報告顯示，全球地熱發電能力將從2020年底的16吉瓦（GW）上升到2025年的24吉瓦，未來5年的總投資將達到250億美元。全球地熱井鉆孔數量將從2019年的223口上升到2025年的380口，這一增長將令從事油井相關服務的油氣供應商松了一口氣。

從2010年到2020年，總共有400億美元投資于新的地熱能開發。目前，美國的地熱額定容量為4吉瓦，占全球主導地位，其次是印度尼西亞、菲律賓、土耳其和意大利。地熱生產排名前10的國家占總市場的90%，許多國家計劃很快進入地熱市場，特別是歐洲。

Rystad能源公司能源服務研究主管Audun Martinsen表示，許多項目仍在規劃階段，并將不得不與風能和太陽能等其他可再生能源競爭。然而，與風能和太陽能相反，地熱發電廠每平方公里的發電量相對較多。

Geothermal Energy Market Heats Up As Big Oil Moves In

Installed geothermal capacity is forecast to expand in the next five years as energy companies diversify into alternative markets, driven by the accelerating energy transition. Global geothermal power production capacity will rise from 16 gigawatts (GW) at the end of 2020 to 24 GW in 2025, a Rystad Energy analysis shows, unlocking total investments of $25 billion in the next five years. The growth will come as a relief to oil and gas suppliers exposed to well-related services as the number of geothermal wells drilled globally will climb from 223 in 2019 to 380 in 2025.

From 2010 to 2020, a total of $40 billion has been invested in new geothermal energy developments. Today’s installed geothermal capacity is dominated by the US with 4 GW, followed by Indonesia, the Philippines, Turkey and Italy. The top 10 geothermal producing countries contribute to 90% of the total market, with many countries planning to enter the geothermal market soon, especially in Europe.

“Many of these projects are still on the drawing board and will have to compete with other renewable sources such as wind and solar. However, contrary to wind and solar, the surface footprint of a geothermal plant has the advantage of being much lower in terms of square kilometers per MW of produced electricity,” says Audun Martinsen, Rystad Energy’s Head of Energy Service Research.
