全球地热能源市场升温

据今日油价10月11日报道，在能源转型加速的推动下，随着能源公司多元化市场发展，预计地热额定容量将在未来5年内扩大。Rystad能源公司的一份分析报告显示，全球地热发电能力将从2020年底的16吉瓦（GW）上升到2025年的24吉瓦，未来5年的总投资将达到250亿美元。全球地热井钻孔数量将从2019年的223口上升到2025年的380口，这一增长将令从事油井相关服务的油气供应商松了一口气。

从2010年到2020年，总共有400亿美元投资于新的地热能开发。目前，美国的地热额定容量为4吉瓦，占全球主导地位，其次是印度尼西亚、菲律宾、土耳其和意大利。地热生产排名前10的国家占总市场的90%，许多国家计划很快进入地热市场，特别是欧洲。

Rystad能源公司能源服务研究主管Audun Martinsen表示，许多项目仍在规划阶段，并将不得不与风能和太阳能等其他可再生能源竞争。然而，与风能和太阳能相反，地热发电厂每平方公里的发电量相对较多。

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.
