Title: TASK: Innovations for a Greener World
Course: GG 22/23 Leuphana-Copy > Section: 2.7 Green // Energy

Using fossil fuels is harmful to the atmosphere, and by extension, to the environment. When fossil fuels are burned, large amounts of CO2 are emitted into the atmosphere, causing atmospheric pollution and accelerating the process of climate change. Therefore, climate scientists call for massive investments into key green energy technologies to accelerate the transition towards sustainability and avoid climate disaster. Furthermore, start-ups stress the importance of green Hydrogen for sustainability and sustainable technology. Let us have a look at two examples:  H2PRO and C-Zero, two promising start-ups innovating in the field of Hydrogen production. Both seek to produce Hydrogen effectively at low cost.

1. Watch the following video, review the materials below and take notes around the following questions:

- What is the difference between grey and blue Hydrogen?
- What makes green Hydrogen more interesting than other types of Hydrogen in the rainbow spectrum?
- How is H2PRO producing green Hydrogen?
- What difficulties did H2PRO face in the beginning and how did the start-up overcome the difficulties?
- What is turquoise Hydrogen and how is C-Zero producing it?

2. Read the text and answer the following questions:
Our approach - Getting to Zero: The Most Ambitious Innovation Efforts in Human History

- Use the tool on the website to guess how much each sector contributes to Greenhouse Gas emissions. Compare your answers to the facts and rank sectors from highest to lowest in terms of Greenhouse gas emissions.
- The Breakthrough Energy website states: "Humans have been innovating in all these areas for thousands of years—but energy transitions can take centuries, and we don’t have time to wait. Right now, we need the most ambitious innovation program the world has ever seen to build and scale clean technologies that can compete with the ones we’re using now." Discuss this approach with your group members. To enrich your discussion, further investigate the main challenges within each sector and how is the Breakthrough Energy Team proceeding to tackle them on the website.

OPTIONAL Hydrogen and decarbonization

Why is Hydrogen vital to decarbonization, and why is decarbonization necessary to transition to clean energy supply?

1. Watch the video below and answer the questions that follow:
- Does Hydrogen exist in a pure form? In what substances do we find Hydrogen?
- Why is Hydrogen considered "clean" energy?
- What are the main advantages and disadvantages of Hydrogen?
- What problem is Europe facing concerning the supply of carbon neutral Hydrogen, and what are the solutions suggested in the video?

After reading the article and watching the video, you should know the relevance of Hydrogen to decarbonization and the latter's importance to the transition to clean energy supply. Discuss your findings with your group members.
