当科学家们试图找到一种方法来减少碳排放并减少我们对化石燃料的依赖时，绿色氢目前被誉为未来的燃料。如果您从未听说过这种形式的燃料或不确定它是如何工作的，那么您并不孤单。绿色氢的概念已经存在一段时间了，但对许多人来说这是一个非常新的概念。尽管联合国和欧盟委员会等政治机构支持这种“新”燃料形式，但公众仍在试图弄清楚这一点。为了帮助您了解可持续能源的最新情况，让本文成为您的绿色氢气生产指南。

什么是绿氢？

氢是宇宙中最丰富的元素之一，几乎是所有生物的一部分。这种元素可以通过化学反应发电，因为它非常易燃。它唯一的副产品是水和热量。绿色氢是仅使用可再生能源生产氢。

绿色氢是如何产生的？

尽管氢的储量极其丰富，但在地球上很难找到纯氢。它主要与水形式的氧气配对。为了“收获”氢，需要分裂含有氢的分子。绿色氢气生产是通过电解完成的。为了提取氢气，我们需要其他能源。太阳能和风能等可再生能源可产生提取氢气所需的电力。

一旦氢被分解并从水分子中提取出来，它就可以直接燃烧或放入燃料电池中。氢气与氧气反应，在电化学电池中产生热量和电力。其他形式的氢提取工艺，例如灰色、蓝色和绿松石色，都使用不可持续的方法，例如热解和蒸汽重整。

绿色氢的好处

如前所述，绿色氢的副产品是水和热量。化石燃料会产生致癌物和化学物质，因此绿氢是一种更清洁的燃料替代品。绿氢来自水，释放水作为副产品，并通过使用可再生能源提取，使整个过程可再生。此外，它可以储存数月而不放电。所有这些都可以大大减少碳排放并减少大气中的温室气体含量。

As scientists try to find a way to reduce carbon emissions and decrease our dependence on fossil fuels, green hydrogen is currently lauded as the fuel of the future. If you’ve never heard of this form of fuel or aren’t sure how it works, you’re not alone. The concept of green hydrogen has existed for some time now, but it’s a very new concept to many people. With political bodies like the United Nations and the European Commission backing this “new” form of fuel, the public is still trying to figure it out. To help you stay informed and updated on sustainable energy, let this article be your guide to green hydrogen production.

What Is Green Hydrogen?

Hydrogen is one of the most abundant elements in our universe and is part of almost every living thing. This element can generate power through chemical reactions, as it’s highly combustible. Its only byproducts are water and heat. Green hydrogen is the production of hydrogen using only renewable energy sources.

How Is Green Hydrogen Produced?

Although hydrogen is incredibly abundant, it’s hard to find pure hydrogen on Earth; it is mainly paired with oxygen in the form of water. In order to “harvest” hydrogen, molecules containing hydrogen need to be split. Green hydrogen production is done through electrolysis. In order to extract hydrogen, we need other energy sources. Renewable energy, such as solar and wind power, generates the electricity necessary for hydrogen extraction.

Once the hydrogen has been split and extracted from the water molecule, it can be burned directly or put in a fuel cell. Hydrogen reacts with oxygen to produce heat and electricity across an electrochemical cell. Other forms of hydrogen extraction processes, such as grey, blue, and turquoise, all use methods that aren’t sustainable, such as pyrolysis and steam reforming.

The Benefits Of Green Hydrogen

As mentioned, the byproducts of green hydrogen are water and heat. Fossil fuels produce carcinogens and chemicals, so green hydrogen is a cleaner fuel alternative. Green hydrogen comes from water, releases water as a byproduct, and is extracted by using renewable forms of energy, making the entire process renewable. Additionally, it can be stored for months without discharging. All of these things can drastically reduce carbon emissions and decrease the amount of greenhouse gases in our atmosphere.
