海洋能源或許是最終的可再生能源

據(jù)今日油價(jià)4月2日?qǐng)?bào)道，盡管潮汐和水波動(dòng)力發(fā)電的大勢(shì)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(guò)他們的潛力。IEA估計(jì)，我們?cè)?018年僅利用了1.2 萬(wàn)億瓦時(shí)的全球大洋能源，這僅占全球一次能源消費(fèi)約17萬(wàn)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(guò)70家公司開(kāi)發(fā)了各種技術(shù)，從海洋潮汐或波浪的動(dòng)能中發(fā)電，導(dǎo)致全球海洋能源生產(chǎn)在過(guò)去十年中增長(zhǎng)了十倍。然而，大多數(shù)人從未超越試點(diǎn)階段進(jìn)入全面商業(yè)化。

海洋動(dòng)力技術(shù)公司（NASDAQ：OPTT）是該領(lǐng)域領(lǐng)導(dǎo)者的悲慘故事，將有趣的科學(xué)項(xiàng)目轉(zhuǎn)變?yōu)榭捎纳虡I(yè)冒險(xiǎn)，這是一個(gè)嚴(yán)峻的現(xiàn)實(shí)。海洋動(dòng)力公司（是一家主要由政府慷慨資助而生存的公司）在過(guò)去三年中暴跌了99%，因?yàn)樗锌赡芗尤虢?jīng)歷過(guò)比土撥鼠日更多虛假曙光的科技公司的垃圾堆。

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.
