海洋能源或許是最終的可再生能源

據(jù)今日油價4月2日報道，盡管潮汐和水波動力發(fā)電的大勢宣傳是清潔能源生產(chǎn)中最大和最后的前沿，但他們從未完全發(fā)揮過他們的潛力。IEA估計，我們在2018年僅利用了1.2 萬億瓦時的全球大洋能源，這僅占全球一次能源消費約17萬TWh的微小一部分。但是，這種悲慘的情況并非并非缺乏嘗試。

超過70家公司開發(fā)了各種技術，從海洋潮汐或波浪的動能中發(fā)電，導致全球海洋能源生產(chǎn)在過去十年中增長了十倍。然而，大多數(shù)人從未超越試點階段進入全面商業(yè)化。

海洋動力技術公司（NASDAQ：OPTT）是該領域領導者的悲慘故事，將有趣的科學項目轉變?yōu)榭捎纳虡I(yè)冒險，這是一個嚴峻的現(xiàn)實。海洋動力公司（是一家主要由政府慷慨資助而生存的公司）在過去三年中暴跌了99%，因為它有可能加入經(jīng)歷過比土撥鼠日更多虛假曙光的科技公司的垃圾堆。

但是現(xiàn)在有些專家認為，藍色能源革命的時機已經(jīng)到來，該領域的新發(fā)展可能會顛覆這一腳本。

國際能源機構的分支機構海洋能源系統(tǒng)(OES) ，一直在全天候工作，匯集其所能做的所有研究，以爭取在不久的將來實現(xiàn)大規(guī)模的海洋動力部署。

The Ocean Could Be The Ultimate Renewable Energy Source

For all their hype as the biggest and final frontier in clean energy production, tidal and wave power have never quite lived up to their potential. The IEA estimates that we harnessed just 1.2TWh of energy from the world’s vast oceans in 2018--a minuscule fraction of the ~170,000TWh in global primary energy consumption. This sad situation is not for lack of trying, though.

More than 70 companies have developed various technologies to generate electricity from ocean tides or the kinetic power of waves, leading to global ocean energy production rising tenfold over the last decade. Yet, most never advance past the pilot stages into full commercialization.

The sad tale of the leader in the space, Ocean Power Technologies Inc (NASDAQ: OPTT), serves as a sobering reality of the enormous challenge of turning an interesting science project into a profitable business venture. Ocean Power--a company mostly kept alive by government largesse--has crashed 99% over the past three years as it threatens to join the trash heap of tech companies that have experienced more false dawns than Groundhog Day.

But some experts now believe that the time for a Blue Energy revolution has come and new developments in the space could flip the script.

The Ocean Energy Systems (OES), an offshoot of the International Energy Agency, has been working round the clock to pool all the research it can in a bid to achieve large-scale ocean power deployment in the near future.
