1 . Climate change has been a long-standing issue that continuously drives scientists to find green, sustainable fuels. The universe’s most abundant element, hydrogen (氢), has drawn their attention and is now on its way to becoming the future of green fuel.

More than $150 billion worth of green hydrogen projects were announced globally in 2020, according to Reuters. Airbus, a European multinational aerospace corporation, has taken the lead in the new sustainable fuel industry. It has designed self-contained hydrogen fuel cell pods that can be attached to the underside of airplane wings, promoting the use of hydrogen fuel for long-distance flights, which aim to achieve zero emissions. The company plans to launch hydrogen-powered aircraft in 2035, according to Daily Mail.

Compared to fossil fuels, hydrogen is a much more eco-friendly fuel. When hydrogen burns, the only by-product is water. However, the traditional way to get hydrogen from natural gas or coal generates considerable carbon emissions. The greenest way is to obtain hydrogen from water using electrolysis (电解) powered by renewable energy, although this process requires so much electricity that it is quite expensive. The key to making hydrogen competitive with fossil fuels is to lower the production cost to under $1.50. This would require lowering around 50 percent of renewable power costs and 75 percent of electrolyzer costs, according to Australia’s renewable energy agency.

Also, shipping liquid hydrogen is challenging, given that needs to be chilled to -253℃ to do so. Japan’s Kawasaki Heavy Industries is set to complete the construction of the world’s first liquefied hydrogen carrier by early 2021. According to Reuters, most of the world’s big hydrogen export projects are looking to ship hydrogen in the form of liquid ammonia (氨), which can be changed to hydrogen and needs to be chilled to only -33 C.

With more and more countries aiming to cut down carbon emissions to solve the issue of global warming, green hydrogen will help decarbonizing industries that can’t be electrified hit the targets.

“We could use these circumstances, where loads of public money are going to be needed into the energy system, to jump forward towards a hydrogen economy,” said Diederik Samsom, who heads the European Commission’s climate cabinet.

3 . Going green seems to be fad (时尚) for a lot of people these days. Whether that is good or bad, we can’t really say, but for the two of us, going green is not a fad but a lifestyle.

On April 22,2011,we decided to be green every single day for an entire year. This meant doing 365 different things, and it also meant challenging ourselves to go green beyond the easy things. Rather than recycle and reduce our energy, we had to think of 365 different things to do and this was no easy task.

With the idea of going green every single day a year, Our Green Year started. My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all green things that could be done to help the environment. We wanted to push the message that every little bit helps.

Over the course of Our Green Year, we completely changed our lifestyles. We now shop at organic (有机的) stores. We consume less meat, choosing green food. We have greatly reduced our buying we don’t need. We have given away half of what we owned through websites. Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made fresh bread. In our home office anyone caught doing something ungreen might be punished.

Our minds have been changed by Our Green Year. We are grateful for the chance to have been able to go green and educate others. We believe that we do have the power to change things and help our planets.
