1. Report Industry Investment Rating - TTF/JKM/HH: Bearish [1] 2. Core Viewpoints of the Report - In 2026, the US natural gas market will shift from balance to surplus as supply growth outpaces demand growth [2][21][22] - European natural gas demand lacks incremental drivers, with overall stable consumption due to the absence of extremely cold winters and high gas prices [3][60] - The Chinese natural gas market will remain in a supply - surplus pattern in 2026, though demand may grow slightly more than in 2025 [4][98] - In 2026, the global natural gas market is in a capacity expansion cycle, and major economies face insufficient endogenous consumption growth. Key benchmark prices will face downward pressure [5][116] 3. Summary by Relevant Catalog 3.1 2025 Natural Gas Market Review - The gas price trend in 2025 was generally in line with the previous forecast. Nymex had the highest volatility, and its price was pushed to a high of 5.4 USD/MMBtu in December [15] - Demand in major consumption areas was weak. Chinese demand shifted from high - speed to low - speed growth, European consumption was stagnant, and US total demand growth was dragged down by negative growth in gas - fired power generation [18] - Supply was in the commissioning cycle. North American LNG liquefaction capacity was released in 2025, and there was a structural adjustment in supply between Asia and Europe [19] 3.2 2026 US Natural Gas Market: From Balance to Surplus 3.2.1 US LNG Exports in 2026 - LNG exports will still lead US demand growth, mainly due to partial commissioning of Golden Pass and the ramp - up of Corpus Christi stage 3 [22] - In 2025, US LNG exports increased by 22 million tons, with a significant increase to Europe and a decline to Asia. The US has become highly dependent on the European market [28] - In 2026, US liquefaction capacity will further grow with the commissioning of Golden Pass's first two liquefaction lines, and PNG exports to Mexico will also increase [37][38] 3.2.2 Gas - Fired Power in the Future - In 2025, US gas - fired power generation decreased in the first three quarters, mainly due to the reverse substitution of coal - fired power caused by high gas prices and the repair of coal - fired power ignition spread [39] - Renewable power, especially photovoltaics, will increasingly squeeze gas - fired power. The future new gas - fired power installations will have limited impact on demand [40][41] 3.2.3 US Dry Gas Production in 2026 - US dry gas production is expected to continue growing in 2026, though the growth rate may be lower than in 2025. The growth is related to capital expenditure inertia and price expectations [50] 3.3 Global LNG Expansion and Russia - EU Energy Decoupling - European natural gas demand remains stable overall, with limited growth in the residential, commercial and industrial sectors. However, gas - fired power demand has increased, especially in Germany and Poland [60][61][62] - European natural gas supply has undergone significant structural adjustments. Further energy decoupling between Russia and Europe is feasible due to sufficient supply from North America and the Middle East. But Russian LNG may put pressure on the spot market [63] 3.4 More Russian Supplies to Asia Affecting the Spot Market - Chinese natural gas demand entered a low - growth stage in 2025, with industrial demand declining and gas - fired power demand increasing. Supply from domestic production and pipeline imports has squeezed LNG imports [96][97] - In 2026, Chinese natural gas demand may grow slightly, but the market will still be in surplus. More Russian LNG flowing to Asia may depress the spot market price [98] - Japanese and South Korean gas demand has a limited impact on Northeast Asia, and overall Asian demand was weak in 2025 [99] 3.5 Investment Recommendations - In 2026, the main benchmark prices TTF, JKM, and HH will face downward pressure. TTF/JKM volatility will be significantly lower than Nymex, making Nymex more valuable for trading. The Nymex price may fall below 3 USD/MMBtu in 1H26 [5][116]
JPEG 活了 30 多年还没被淘汰!后浪一波接一波,它凭啥仍是“网图扛把子”?

为什么 JPEG 仍然统治着网络? 三十年前, JPEG 成为我们在互联网上分享数码照片的主要方式 1. 引言 近三十年来,JPEG 一直是万维网的主流图像格式。但它并非网络最初的选择。事实上,首款主流图形浏览器 NCSA Mosaic 最初并不支持嵌入式 JPEG 文件——只支持嵌入式 GIF,以及其他几种已被历史遗忘的格式。然而,JPEG 相比其迅速取代的格式具有诸多优势。 当时 Ernie Smith 在 Tumblr 上转发了这段采访(那时 Tumblr 正是 GIF 的"宇宙中心")。很快,这条帖子被转发数千次,几乎所有人都在反驳威尔特。 不久后,他的这段话甚至成了网络迷因。 这个故事折射出威尔特(2022 年去世)的创作模式:他并非通过委员会协作开发格式。正因如此,他可以自行定义发音。1987 年,作为 CompuServe 员工的他接到开发任务,独自完成了这个产品。最初描述其工作原理的文档?简单到极致。三十八年后的今天,我们仍在使用 GIF,但它从未达到 JPEG 的普及程度。 而大约五年后正式诞生的 JPEG 则完全不同。两者的差异,本质是"事实标准"与"正式标准"的区别,而这正是 JPEG ...
