航太產業徹底改變了旅行方式。

But now the industry is facing its biggest ever challenge.

但現在這個產業正面臨有史以來最大的挑戰。

Aviation is one of the fastest growing sources of greenhouse gases.

航空是溫室氣體成長最快速的來源之一。

Currently, it's responsible for around two and a half percent of all carbon emissions.

目前，它佔了所有碳排放的約百分之二點五。

In fact, if the industry was a country, it would be one of the world's top 10 polluters.

事實上，如果航空業是一個國家，它將會是全球前十大汙染國之一。

IATA member airlines have committed to achieving Net Zero by 2050.

國際航空運輸協會的會員航空公司已承諾在2050年前達成淨零排放。

But with the aviation sector being one of the hardest to decarbonize, that won't be an easy task.

但由於航空業是最難脫碳的產業之一，這將不會是一項容易的任務。

It's the simplest and most abundant element in the universe.

它是宇宙中最簡單、也最豐富的元素。

To make it, we need to isolate the hydrogen from water molecules.

There are various ways to do this, but the most common is steam methane reforming, or or smr.

The process heats and pressurizes methane from natural gas to isolate hydrogen atoms.

在地球上，它主要存在於水中。

There are two resulting products, grey and blue hydrogen.

Grey hydrogen production releases greenhouse gas emissions.

Blue hydrogen uses carbon capture and storage to offset emissions.

要製造它，我們需要從水分子中分離出氫。

SMR is by far the most common way we produce hydrogen.

有許多方法可以做到這一點，但最常見的是蒸汽甲烷重組，也就是smr。

But the entire process won't help aviation reach its net zero goals.

但整個過程無助於航空業達成淨零排放目標。

The most common method for creating green hydrogen is via electrolysis, where electricity is used to isolate water's hydrogen atoms in an electrolyzer.

製造綠色氫最常見的方法是透過電解，也就是利用電力在電解槽中分離水分子的氫原子。

If the source of the electricity is renewable, then the entire process is carbon free, and

如果電力的來源是再生能源，那麼整個過程就是零碳排放，而且

the resulting fuel can be used in planes in one of two ways.

所產生的燃料有兩種方式可用於飛機。

The first is very similar to the way fossil fuels are used now, that is, via a combustion engine.

第一種方式與現在使用化石燃料的方式非常相似，也就是透過燃燒引擎。

This way reverses the electrolysis process, using hydrogen as a fuel to generate electricity that can then be used to power planes.

這種方式逆轉了電解過程，利用氫作為燃料產生電力，然後用於驅動飛機。

Fuel cells, although expensive and complex, are more efficient, quieter, and lighter than hydrogen combustion engines.

燃料電池雖然昂貴且複雜，但比氫燃燒引擎更有效率、更安靜、更輕巧。

Hydrogen fuel operates at really high temperatures, which is less than ideal when dealing with a highly flammable chemical element.

氫燃料會在非常高的溫度下運作，這對於處理高度易燃的化學元素來說，並不是最理想的。

The Hindenburg disaster in 1937 demonstrated just how easily hydrogen can go up in flames, a tragedy that all but ended airship travel.

1937 年的興登堡號空難就展示了氫氣有多容易起火，這場悲劇幾乎終結了飛艇旅行。

Hydrogen is also less dense than jet fuel, so it requires more storage room.

氫氣的密度也比噴射燃料低，所以需要更多的儲存空間。

That's why this plane doesn't have windows at its rear.

這就是為什麼這架飛機的後方沒有窗戶。

The space is needed to store hydrogen fuel, though some propose adding passenger seats over wings to get around the issue.

這些空間是用來儲存氫燃料的，雖然有人提議在機翼上方增加乘客座位來解決這個問題。

If hydrogen were to be produced at airports, then they would need to be repurposed to look something like this.

如果要在機場生產氫氣，那麼機場就需要改裝成類似這樣的樣子。

Green hydrogen is really expensive to produce.

綠色氫氣的生產成本非常高昂。

The International Renewable Energy Agency estimates that it is two to three times more costly to produce than oil and gas, so prices will need to come down before it's widely adopted.

國際再生能源總署預估，它的生產成本是石油和天然氣的兩到三倍，所以價格必須先降下來，才能廣泛採用。

But there are initiatives underway to help solve all of these issues.

不過，目前已經有一些計畫正在進行，希望能解決所有這些問題。

In May 2024, the US Congress outlined a viable path for hydrogen powered commercial aircraft by approving the FAA Reauthorization Act 2024, which supports the development of the US hydrogen aviation industry.

在2024年5月，美國國會通過了《2024年FAA授權法案》，為氫動力商用飛機指明瞭一條可行的道路，支持美國氫能航空產業的發展。

And the UK's Civil Aviation Authority has launched the Hydrogen Challenge Sandbox to address challenges associated with zero carbon emission aviation fuel.

英國民航局也推出了「氫能挑戰沙盒計畫」，來解決零碳排放航空燃料相關的挑戰。

Against this backdrop, most hydrogen plane manufacturers are aiming for short to medium haul passenger flights to begin operations by 2030.

在這樣的背景下，大多數氫能飛機製造商的目標是希望在2030年前開始營運中短程載客班機。

By then, the hydrogen aircraft market could be worth $7.4 billion.

屆時，氫能飛機市場的價值可能高達74億美元。
