Exploring the Gobi Desert's Potential [02:27]

Lei Zhang begins his talk by painting a vivid picture of the Mongolia Gobi Desert, describing it as "the most Mars-like planet" due to its extreme conditions—temperatures plummeting to -40°C in winter and soaring to 40°C in summer. Despite its harshness, Zhang expresses a profound admiration for the desert:

“When people see useless barrenness, emptiness, I see abundance.” ([02:27])

He envisions the Gobi Desert as a new frontier for human civilization, rich with renewable energy resources that are both abundant and free.

---

Energy and Economic Growth Correlation [04:11]

Zhang delves into the historical relationship between energy consumption and economic prosperity. He presents a thought-provoking equation:

“2000 years before the industrial revolution, our global GDP only grew five times because we were only able to use five times more energy.” ([04:11])

Post-industrial revolution, this relationship skyrocketed:

“Our global GDP expanded 100 times because we are using 100 times more energy.” ([04:12])

This correlation underscores the critical role of energy in driving global economic growth.

Harnessing Renewable Energy in Deserts

Zhang outlines three primary challenges in leveraging desert environments for renewable energy:

1. Capturing Wind Energy [04:53]

   • Designing wind turbines capable of surviving extreme desert winds is paramount.
   • Solution: Development of robust wind turbines that can efficiently capture and convert wind energy into electricity.

2. Reducing Transmission Costs [06:15]

   • Long-distance transmission lines are prohibitively expensive.
   • Solution: Establishing large-scale, off-grid renewable systems that integrate wind turbines, solar panels, storage solutions, and AI-driven orchestration.

3. Utilizing Local Electricity [07:45]

   • Maximizing the use of locally generated electricity is essential.
   • Solution: Creation of net-zero industrial parks that produce energy-intensive products like batteries, green hydrogen, and ammonia.

The Nazir Industrial Park: A Model of Sustainability [10:30]

Zhang showcases the Nazir Industrial Park, situated in the heart of the Gobi Desert, as a pioneering example:

“It is totally off-grid, 100% powered by renewable energy, producing state-of-the-art batteries at the lowest cost among our envisioned production bases.” ([10:30])

Key highlights include:

• Green Hydrogen and Ammonia Production: The park hosts the world’s largest green hydrogen project, targeting 1.5 million tons with the first phase ramping up to 300,000 tons.
• Cost Reduction Goals: Aiming to make green hydrogen as affordable as grain, recognizing that energy growth stems from cost reductions.

---

Innovations Driving Cost Parity [12:20]

Achieving cost parity between renewable and fossil fuels is crucial. Zhang discusses several technological advancements facilitating this:

• AI-Regulated Wind Turbines: Enhanced energy capture through intelligent design.
• Hybrid Energy Storage Systems: Combining lithium batteries with supercapacitors to reduce grid support costs.
• Advanced Electrolyzers: Improving membrane and electrode efficiency to lower green hydrogen production costs.
• Modular Hydrogen Plants: Simplifying desert construction through prefabricated, scalable units.
• AI-Driven Grid Management: Utilizing predictive models for weather and energy supply to automate grid operations.

“By redesigning the entire energy system and equipment, we can significantly reduce costs and achieve the necessary parity.” ([14:15])

---

Vision for the Future: Unlocking Human Prosperity [14:50]

Zhang shares an inspiring vision for a future empowered by renewable energy:

“Imagine harvesting super intelligence with AI data centers everywhere, desalinating seawater to transform deserts into green oases, and reversing the climate crisis by converting atmospheric carbon into building materials.” ([15:30])

He envisions:

• Advanced AI and Data Centers: Facilitating unprecedented levels of intelligence and efficiency.
• Desalination and Agriculture: Turning arid regions into fertile, productive landscapes.
• Climate Restoration: Actively removing carbon from the atmosphere to combat climate change.
• Interstellar Travel: Making space exploration a routine aspect of human civilization.

[Lei Zhang]

My favorite place is in the Mongolia Gobi Desert. It's most Mars like in the planet, barren and empty. Wind blows all year round. Sandstorms happens often. In the winter, temperature is as low as -40 degrees. In the summer it reaches 40 degrees. It's useless, but it's my most favorite place. I come To Gobi with a belief. I believe this could be the new space for our civilization. When people see useless barrenness, emptiness, I see abundance. Abundance. If you look at the barren desert, it is filled up with abundant renewable energy. The strong wind and the shining sun. They are infinite and never end. I found out the important equation between energy and our prosperities. 2000 years before industrial revolution, our global GDP only grew 5 times.

[Sean Linda]

Why?

[Lei Zhang]

Because we are only able to use 5 times energy. Natural energy, agriculture, then transfer to muscle power. Since industrial revolution, our global GDP expanded 100 times because we are using 100 times more energy. So abundant fossil fuel energy has been turned and create forces to drive the machines. Create materials like steel, create fertilizer, to improve the food production. Today it even creating tremendous intelligence for humanity. So how can we unlock such a big potential from desert to push humanity to the next level prosperity? Because one hour solar radiation is able to meet our entire annual demand of energy. It is free and it is green. In front of Gobi, we have to solve three challenges. The first one, how can we capture the rough and the raw wind energy? Just as steam engine is able to turn coal energy into motion, we end up with wind turbine to capture wind energy to turn into electricity. Most importantly is to really design the wind turbine is able to survive in the extreme wind condition in the desert. Secondly, how can rebuild avoiding to build a long distance or thousand miles transmission lines which is costly and extremely expensive. We end up with the largest off grid renewable system by integrating wind turbine solar panel storage with AI orchestrations. Okay, then the last remaining challenge. How can we utilize such abundant locally made electricity? We end up with a solution to build net zero industrial park which is going to produce energy intensive products like batteries and green hydrogen and ammonia, those green molecules. Why green ammonia? One ton of green ammonia is able to hold 10,000 kilowatt hour electricity. Most importantly, the green molecule is so important for us to decarbonize our economic system. It's the most difficult hard to obey segment. The green hydrogen is going to be used to make green steel, to make natural chemicals, to make green aviation and shipping. So what's about today? Just right in the heart of Gobi Desert, the first Nazir industrial park has been built. It is totally off grid 100% by renewable energy. It is making the state of art battery. But most importantly, it is the lowest cost of battery among our envisioned production base. Why? Because it's tremendous, free, abundant renewable energy. And we are also building in the desert the largest green hydrogen project in the world. 1.5 million ton green hydrogen and green ammonia. The first phase, 300,000 ton is commissioning. Now we are not supposed to build the largest. Our goal is to make the cheapest to make green hydrogen as cheap as grain. Why the cost is so vital? Because history told us this 100 times. Energy growth is a result of cost reductions. In order to unlock these tremendous renewables, we have to make renewable energy much lower than fossil fuel. There are two forms of energy. One is electron, one is molecule. Today renewable has already win the battle against electricity. So renewable energy is much lower on making electricity. But there's still another battle is green molecule is about two or three times expensive than green molecule from coal and gas. We have to make as cheap as possible have this cost parity to the grain. So we should redesign the entire energy system and redesign the equipment. Then reduce cost significantly. So first we designed AI regulated wind turbine which is able to capture more energy. Why reduce cost significantly? We are also designing the world first hybrid energy storage system. By combining lithium battery with super capacitor is able to supporting grid with much less cost. And we are improving the efficiency of electrolyzer by innovating membranes and electrodes significantly. In order to make the construction work in the desert much easier, much cheaper. We designed a modular prefabricated hydrogen plant which is made construction work in the desert is as easy as stacking Legos. And we are also developing AI physical model starting from predicting weather, wind and solar to manage grid automatically. So today we already achieving the lowest cost of green hydrogen and green ammonia in the world. But there are still some gaps. I believe within three years, by 2028, we are able to make such cost parity to grain. Why I'm so convinced if you look at last 20 years, the cost of wind and solar have been reduced 90%. For the last five years, the cost of energy storage has been reduced 90%. End of the day, the green electricity still be majority cost of green hydrogen. So by combining the significant improvement on the electrolyzer and hydrogen factory, we are for sure to achieve such a cost parity. By the time we achieving cost parity to grade for molecules, it is going to be a milestone for our humanity. Because we are going to remove the last bottleneck which preventing us to unlock tremendous renewable energy. It's last bottleneck, it is going to open the gate to tremendous new possibilities. Just imagine, as we repeated in the history, within next 100 years, if we are able to use 100 times more energy, how the world will look like we are going to harvest the super intelligence with AI data center everywhere. We are going to desalinate seawater and turn the desert into green oasis. We are going to remove poverty by producing our food and protein in the basement. We are going for sure to reverse climate crisis by taking carbon from the air and turn into building materials. And we are even able to make interstellar traveling as a daily routine. So where's the answer? The answer just right in the heart of the desert. From Sahara in Africa to Middle east, from Australia to Gobi, there are a hundred times energy than what we need. It's infinite, green and free. It's up to our tech knowledge. So ladies and gentlemen, this net zero transition is not a costly burden for us. It is indeed the one and only pathway for us for our humanity to achieve a new great prosperity. Thank you. Thank you.
