Geothermal energy potential found in Taitung’s Wulu
Geothermal energy potential found in Taitung’s Wulu
2024-12-29
Taiwan has been exploring geothermal energy for 50 years. To achieve carbon neutrality by 2050, the Industrial Technology Research Institute and the Economics Ministry have teamed up to create a "national geothermal team." They’ve recently made a major discovery that Wulu in Taitung’s Haiduan Township has potential for deep geothermal development. For the first time, researchers have retrieved a complete, three-meter-long core sample from a depth of 2,000 meters. That’s equivalent to four Taipei 101s.
These fully equipped staff are hard at work at the Wulu geothermal well in Taitung’s Haiduan Township. The shaft is as deep as four Taipei 101s.
Senior researchers with the Industrial Technology Research Institute have joined with the Ministry of Economic Affairs to conduct exploration in these mountains, day and night. After five years, they’ve for the first time recovered a complete, 3m-long core sample of granite.
Granite has never been found before in Taiwan’s southeast. The team carefully transported the sample back to Taipei to find out if the heat from the earth’s core can generate electricity.

It’s actually difficult to access the southern mountains. Metamorphic rock is extremely hard. Then it’s also along an orogenic belt, so there are a lot of fissures. Down at the bottom of this 2,000m shaft it reaches over 145 degrees.
Taiwan has been exploring geothermal energy for over 50 years. After setting up the first volcanic geothermal plant in New Taipei’s Jinshan, researchers have been working their way across the Southern Cross-island Highway. Now they’ve set a major milestone.

Before, we said we had no idea how hot it was underneath the Central Mountain Range. The first time we entered the central mountains, this core region, we extracted a wealth of precious materials. Elsewhere in the world, this typically means it’s a steppingstone to deep geothermal, a geological requirement. Of course, we don’t fully understand this granite. It’s the first discovery, so there are still lots of unknowns to be researched.
The national geothermal team is going all-out with plans to generate 1,000MW of power from geothermal between 2028 and 2030, hoping to set Taiwan’s green future on the right path.

地熱國家隊重大突破! 台東霧鹿具開發深層地熱潛力
2024-12-29
國內探勘地熱能源已經超過50年，為了達成2050年淨零碳排目標，工研院、經濟部等攜手合作，組成的地熱國家隊，有了重大進展，發現台東海端鄉霧鹿，具有開發深層地熱潛力，研究團隊首度取回完整、且長達三米的岩芯，完成深度2000米的探勘，這個深度、相當於四座101大樓的高度。
工作人員全副武裝，這裡是台東海端霧鹿地熱探勘井，這座地熱井深達四座台北101。
在山區探勘，不分日夜，工研院資深研究員和經濟部聯手，歷經五年時間，首度取回完整、長達三米的花崗岩連續岩芯。
在台灣東南部，從沒發現過花崗岩地質，調查團隊小心翼翼，把岩芯從山區運回台北，要研究出地底的熱能能否發電。

“在南橫的山區，其實很不好到達，變質岩層其實非常堅硬，再加上它位於造山帶，所以裂隙也很多，在這個兩千米的井底，溫度又高達145度以上”
國內探勘地熱能源已經超過50年，除了新北金山這座第一座火山型地熱發電廠，國家隊們也已經在南橫公路山區默默耕耘，完成重大里程碑。

“我們過去常說，不知道中央山脈到底底下溫度有多高，那我們第一次進到中央山脈的，算是蠻核心的地方，我們取到了相當豐富而且寶貴的資料，那些東西通常在國際上的意義，就是進深層地熱的一個敲門磚，有這樣的地層條件，那當然我們對這一塊花崗岩，也並沒有完全的了解，甚至第一次探到，還有很多未知的項目要去做研究”
地熱國家隊卯足全力，計畫在2028年到2030年，把地熱發電擴增到1000MW，讓台灣綠能路，穩穩走下去。
