海洋能源或许是最终的可再生能源

据今日油价4月2日报道，尽管潮汐和水波动力发电的大势宣传是清洁能源生产中最大和最后的前沿，但他们从未完全发挥过他们的潜力。IEA估计，我们在2018年仅利用了1.2 万亿瓦时的全球大洋能源，这仅占全球一次能源消费约17万TWh的微小一部分。但是，这种悲惨的情况并非并非缺乏尝试。

超过70家公司开发了各种技术，从海洋潮汐或波浪的动能中发电，导致全球海洋能源生产在过去十年中增长了十倍。然而，大多数人从未超越试点阶段进入全面商业化。

海洋动力技术公司（NASDAQ：OPTT）是该领域领导者的悲惨故事，将有趣的科学项目转变为可盈利的商业冒险，这是一个严峻的现实。海洋动力公司（是一家主要由政府慷慨资助而生存的公司）在过去三年中暴跌了99%，因为它有可能加入经历过比土拨鼠日更多虚假曙光的科技公司的垃圾堆。

但是现在有些专家认为，蓝色能源革命的时机已经到来，该领域的新发展可能会颠覆这一脚本。

国际能源机构的分支机构海洋能源系统(OES) ，一直在全天候工作，汇集其所能做的所有研究，以争取在不久的将来实现大规模的海洋动力部署。

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.
