據油價網1月16日消息稱，國際能源署(IEA)在本周的一份新報告中表示，隨著世界進入一個新的工業時代，清潔能源技術制造將引領潮流，在2050年實現凈零排放的情況下，到2030年，清潔能源技術和基礎設施的總投資必須超過4.5萬億美元。所需投資規模空前，需要各國制定產業戰略，在所有區域、技術和供應鏈上調動這些投資。IEA表示，任務艱巨，而且由于原材料和材料加工高度集中在少數幾個國家，風險也更大。

該機構表示，阻礙清潔能源技術強勁發展的其他障礙包括政策和供應鏈瓶頸。

IEA在報告中表示：“政策和監管風險、對示范性和首創項目缺乏信心、項目管道的不確定性、貨幣穩定性等更廣泛的宏觀經濟因素，以及地緣政治事件，都可能導致瓶頸發生。”

該國際機構指出，對清潔能源的投資正在持續增長，但如果世界有機會在2050年實現凈零排放，就需要進一步增加，特別是在這十年。

去年，清潔能源投資達到1.4萬億美元，比2021年增長10%，占能源部門總投資增長的70%。

然而，國際能源署表示，化石燃料仍占全球一次能源結構的80%。

能源轉型取決于清潔能源技術的供應鏈。將需要多達1.2萬億美元的累計投資，以使供應鏈具備足夠的在線產能，從而實現NZE情景（凈零排放情景）的2030年目標。目前宣布的投資約占這一估計的60%。

IEA表示，考慮到從決策到生產的周期，大部分投資將在2023—2025年期間進行，平均每年2700億美元，這幾乎是2016—2021年平均投資速度的7倍。

“建立新供應鏈和擴大現有供應鏈的準備時間可能很長，目前需要政策干預。開礦或部署清潔能源基礎設施可能需要十多年的時間。建立工廠或擴大大規模生產技術的運營只需要大約1至3年。”

除了需要擴大投資，現在就加大投資，以便在2030年啟動和運行項目外，世界還需要實現清潔能源供應鏈的多樣化。

國際能源機構表示：“關鍵礦產的生產在地理上高度集中，引發了人們對供應安全的擔憂?！?/p>

IEA: World Needs $4.5 Trillion Investment In Clean Energy Tech By 2030

As the world enters a new industrial age, where technology manufacturing for clean energy will lead the way, total investments in clean energy technologies and infrastructure have to top $4.5 trillion in 2030 under the net-zero emissions by 2050 scenario, the International Energy Agency (IEA) said in a new report this week. The unprecedented scale of required investment will need industrial strategies from the countries to mobilize those investments across all regions, technologies, and supply chains. The task is enormous, and risks are also greater due to the heavily concentrated raw materials and material processing in a handful of countries,the IEA said.

Other hurdles to a robust development of clean energy technology include policy and supply chain bottlenecks, according to the agency. 

"Bottlenecks can occur as a result of policy and regulatory risks, a lack of confidence in demonstration and first-of-a-kind projects, uncertainty about project pipelines, wider macroeconomic factors such as currency stability, and geopolitical events," the IEA said in its report.

Investment in clean energy is continuously rising, but it needs to rise much more, especially this decade if the world has a chance to reach net-zero by 2050, the international agency noted.

Last year, clean energy investment hit $1.4 trillion, a 10% increase compared to 2021, and representing 70% of the growth in total energy sector investment.

Yet, fossil fuels still account for 80% of the primary energy mix in the world, the IEA said.

The energy transition depends on the supply chains in clean energy technology. As much as $1.2 trillion of cumulative investment would be required to bring enough capacity online for the supply chains to be on track with the NZE Scenario's 2030 targets. Currently announced investments cover around 60% of this estimate.

Considering the lead times from decision to production, most investments will have to be made during 2023-2025, at an average of $270 billion per year, which is nearly seven times the average rate of investment over 2016-2021, the IEA said.

"Lead times to establish new supply chains and expand existing ones can be long, requiring policy interventions today. Opening mines or deploying clean energy infrastructure can take more than a decade. Building a factory or ramping up operations for mass-manufactured technologies requires only around 1-3 years."

Apart from the need to scale up investments, and to do that now for projects to be up and running in 2030, the world needs to diversify its clean energy supply chains.

"The production of critical minerals is highly concentrated geographically, raising concerns about security of supplies," the IEA says.
