0:00.0 | It's Ted Talks Daily, I'm your host, Elise Hugh. |
0:07.4 | We're about to hear a case for the fuel source of the future, Green Hydrogen. |
0:13.5 | In her talk from Ted 2022, Green Hydrogen Entrepreneur Vitea Cohen explains the possibilities for |
0:19.4 | it and how it's not only cheaper and more sustainable than fossil fuels, but could |
0:24.2 | drive a new industrial revolution. |
0:38.2 | In this episode, researcher and activist, Zaru J. Arama talks about her nationwide campaign for a fair wage in the service industry. |
0:54.2 | We're in a very historic moment where after 160 years of this wage structure lasting since emancipation, it is finally being rejected by millions of workers. |
1:05.2 | And for Ted Talks Daily comes from Airbnb. |
1:08.2 | Okay, every time you stay at an Airbnb, do you ever wonder, could my place at home actually be an Airbnb, could I rent it out? |
1:16.2 | And if I could, what would it earn? I think about this sometimes, myself. |
1:21.2 | So I was pretty surprised to hear about Lucy and Worcestershire, who realized she could convert her empty barn space into a one bedroom Airbnb. |
1:30.2 | How creative, right? Now her extra income allows her to focus on her family as a new mom. Find out what your place could be earning at Airbnb.co.uk slash host. |
1:43.2 | We're going on a field trip together. We're going back to middle school, to chemistry class. Do you remember this? |
1:51.2 | It was an experiment we did with saltwater, the battery, and two pencils. Guess what? The reaction you witnessed then is a key to tackling climate change. |
2:01.2 | Yes, at 14 years old, we already knew. And today we have the means to replace fossil fuels with green hydrogen. Let's walk through this. |
2:13.2 | The experiment I'm alluding to is called water electrolysis. And it is a way to create hydrogen. On earth, hydrogen is found in the greatest quantities in water. |
2:25.2 | H2O. And when you use renewable electricity to split water into H and O, that's green hydrogen. And the device creating this reaction is called an electrolyzer. |
2:40.2 | There are other colors of hydrogen out there, but they use fossil fuels. So we're not going to talk about those today, but only make climate change worse. |
2:49.2 | We are talking about green hydrogen, which is 100% clean. And the quickest path to scaling green hydrogen is by mass producing electrolyzers. |
3:02.2 | But first, why do we need green hydrogen? When we look at our global energy consumption today, only 20% comes in the form of electricity or electrons. |
3:13.2 | This means there are many 80% of our world's energy use is in the forms of molecules. And while the world is making rapid progress in greening our electricity, we need to look towards our molecules as well. |
3:27.2 | Think about your industry, transport, heating and cooling sectors. They're all powered by molecules. And yes, this means largely by fossil fuels, coal, oil, and gas. |
