I'm your host Elise Hu. It's clear there are so many mind blowing ideas and solutions already out there for tackling climate change. So how do we scale up the solutions for climate tech innovator Xu Hao? It's a lot about how we make these solutions profitable. In his talk he explains that we already have the Science to turn for example, captured CO2 into plastic or Even jet fuel. But we need more infrastructure to scale up to accelerate climate action. Across the globe.

Humans have been using alcohol for thousands of years. But when did we understand it soberly? It wasn't until the 1700s that scientists first discovered the formula of alcohol, C2H5. Oh, that. Alcohol finally got its professional LinkedIn profile called Ethanol and started working as an important chemical. Advances in engineering and business have since enabled large scale production of ethanol. And today it is a $114 billion industry. We use it in cosmetics, in fashion, in medicine, in food, and obviously beverages. And it's even more relevant today as fuel and raw material for some of the low carbon industries. So why am I telling you about alcohol? Because it is a good example of how science, engineering and business work together to change the world. But it actually took ethanol more than 200 years to do so. We simply couldn't wait that long. To tackle our climate challenge, we urgently need to speed up and scale up low carbon solutions. So, my name is Xuhao and I lead Tencent's climate change initiatives. We are a major Chinese tech company with products in social media, with video games and cloud services. And we also care about climate change. It's not just limited to data center efficiency or sourcing of renewable energy. As important as that is, my colleagues and I have been working to explore how we could contribute to the acceleration of low carbon technology innovations. That's why we launched CarbonX program. And three years in, we are actually more optimistic than ever. Why? Because we felt the right answer is not so complicated. We already have lots of innovation in science, in engineering and business. And the secret to further accelerate the process is also simple. Just do them all at once. Let me further explain. First, most of the scientific discoveries needed to decarbonize our economy has already been made. Really? Today, we generate electricity from solar and wind. We store energy using chemistry or physics. We turn carbon dioxide into all kinds of chemicals. And nuclear fusion is also on the Horizon. All right, 100 years already saved. Let me give you a specific example. CRISPR is a genetic scissor that well known in the pharmaceutical industry. They use it to edit genetic code to find cures for diseases and new drugs. But it can be applied to carbon too. Take gas Jim, a Chinese startup, they actually apply CRISPR to a certain bacteria called clostridium so that these little guys can actually feed on carbon dioxide and produce butanol. So why does butanol matter? Because together with our old friend ethanol, as well as butanol, we actually get ethylene Glycol, polyethylene, polypropylene, butylacetate, dibutylphosphatelate, tributyl citrate, and many more. A bit lost, right? These are. The chemicals are actually used in paint, clothes, toys, water bottles, furniture, and the list goes on and on and on. Essential to everyday life, but all made out of fossil fuel. Today, with claustridium, we could potentially make all of them using carbon dioxide instead. It's really great science. So it's not the science holding us up. What about engineering? Very important, but unglamorous. Well, engineering requires lots of innovation too, because we have to replicate a success in the laboratory test tubes and scale up it in a much, much bigger way, from grams to kilograms to tens to millions of tons. Eventually a big factory. To do that, engineers often face two challenges. First, how to build a factory faster and cheaper. And then how to operate it effectively. Let's say we want to build a plant that produce 20,000 tons of clean chemicals using carbon dioxide. Do we build one big reactor or a few smaller ones? This is where the process engineers come in. How much pressure is needed in these reactors? What are the flow rates needed for the gases or the liquids so that they are balanced and the production are most effective? How much land such a facility will occupy? How does it integrate with the existing factory? And probably most importantly, how can we build such a plant faster and cheaper? Well, all of these considerations determines the fans, pumps, compressors, reactors, and all the other parts we will use. And whether we could use off the shelf, standardized equipment, because otherwise, if we have to design novel parts, it will be much more expensive and often takes much longer. So it's almost like pick up pieces of Lego blocks. To build a beautiful model of your own design, both creativity and discipline are needed at the same time. Then it comes operational efficiency. Feynman Dynamics is another startup. They actually combine carbon dioxide and green hydrogen to make green hydrocarbons and produce sustainable aviation fuel or saf, that could potentially clean up our flights. So the key is actually a catalyst that can efficiently convert carbon dioxide into carbon monoxide. The engineering challenge here is how to manufacture such a high quality catalyst at much bigger volume. The process is almost like make a fruit smoothie. You need to blend fruits just right to get a delicious drink. But when you try to make much bigger batches, sometimes the blender got too hot or the fruit doesn't mix well. That will jeopardize the taste of our drink. To tackle this challenge, engineers at Feynman Dynamic actually designed, actually borrowed practice from from pharmaceutical chemistry, they designed a special high speed mixer that passes the chemicals at really high velocity in a tube and then circulates back the finished product back to the main reactor to make high quality catalysts. It's almost like you pre blend avocados and apples first and then put them back into the big blender to get the ultimate drink. So this rather small engineering staffs actually enabled Feynman Dynamics to produce their catalyst at industrial scale. So today SAF is still more than five times more expensive than conventional jet fuel. But with lots of innovation like this, and also the production at scale, I believe SAF can beat jet fuel in cost within 10 years time. So the engineers are hard at work. But what about business? Because business is all about price, cost, market and profitability. And in order to reduce carbon emission in the scale of gigatons, startups must turn their science and engineering innovation into profitable ventures. But we got plenty of good news here too. Some of the technologies are approaching the moment where they cost the same or even less than the fossil fuel alternative, sometimes without a carbon price. Yuan Chu is a startup that makes calcium carbonate out of carbon dioxide. Calcium carbonates may also sound unfamiliar, but these white powders are actually in our everyday life. From paper to toothpaste, to washing powders to car tires. By using leftover calcium from biomass or the steel making industry, Yuan Chu can actually produce high quality calcium carbonate cheaper than the conventional method which is digging limestone out of the ground and burning lots of fossil fuel to make it great Green discount, right? Then sometimes business is all about the size of the eventual market. Moguang is another startup that actually developed this really groundbreaking new material called radioactive cooling. So this material not only reflects 93% of sun radiation back, it could achieve additional cooling by radiate the heat back to to outer space, leveraging certain wavelength cooling window. Guess what requires cooling? Melting glaciers. And that's why we launched a pilot project with Moguang in Dagu Glacier, one of the endangered glaciers near Tibetan Plateau. Over the past three years, the melting has slowed down by as much as 80%. But. But the project itself is actually not a business. Guess what? It is any surface that requires cooling. So that's your mobile phone, glass wall of a building, or data centers. So the great news is not only Moguang covered glacier with this material, they already integrated many of their material into hundreds of thousands of mobile phones and sports cameras. And expanding to other products very quickly. So there is truly huge market potential. All right, so the science is here. The engineers are hard at work and the business model are scaling up. So our final question is can we further accelerate? Of course we can, simply by bringing together scientists, industry experts and and the business people in the same room. So they start to thinking about all the tough questions from the very beginning at the same time. So the scientists will probably ask how much gigajoule of energy is required to capture one ton of carbon dioxide. The industry expert will ask how does your technology help me decarbonize my industry and how does it fit into my factory? And the investor will probably ask what's your plan to grow your business by 100 times in the next five years and to go public. This is almost exactly what happened at Carbonx program. Let's just say this productive dialogue, heated debate, sometimes really disagreement can be challenging, but it really help speed up the process because it got everybody to thinking about everything at the same time, not waiting 200 years like alcohol now. Remember Gastrin and those cute Claustridium? We recently launched a clean chemical consortium that brings consumer brands, big chemical companies and startups like Gasgene or Yuan Chu to try to make everything out of carbon dioxide. That's also working on science, engineering and business all at once. So by now hopefully you guys understand why I felt we should every reason to be really optimistic because we already have plenty of scientific discovery, engineering, innovation and business models so that we should be inspired to imagine a world with net zero and cleanliness future most likely much better than what AI can generate for us today. Therefore, I'm definitely drunk on the possibility of a better and cleaner future. Cheers everyone. Thank you.

Speaker: Xu Hao
Main Theme: How new innovations are enabling us to transform carbon pollution—especially captured CO₂—into everyday products like chemicals for toys, toothpaste, plastics, and more, at scale, by uniting advances in science, engineering, and business.
Xu Hao, who leads Tencent’s climate change initiatives, shares a vibrant and hopeful look at how humanity is now able to turn pollution—specifically carbon dioxide—into valuable, everyday products. Drawing on examples from Chinese startups and initiatives at Tencent, Hao illustrates that the necessary scientific discoveries already exist, but accelerating deployment and scaling solutions require the integrated efforts of scientists, engineers, and business leaders. He presents the journey from lab innovation to gigaton-scale real-world impact and makes a strong case for optimism about achieving net-zero emissions.
[02:44]
[04:38]
Most scientific breakthroughs for decarbonizing the economy already exist.
Example: Using CRISPR not just in medicine, but to engineer bacteria that feed on CO₂ to create useful chemicals.
“Today, with clostridium, we could potentially make all of them [common chemicals from toys to water bottles] using carbon dioxide instead. It's really great science.”
—Xu Hao, [05:52]
[06:18]
The next bottleneck: transitioning from test-tube successes to industrial scale.
Key challenges:
Metaphor: Assembling factories like Lego—balancing creativity and discipline.
Example: Feynman Dynamics (startup) produces green aviation fuel by combining CO₂ with green hydrogen, needing highly efficient catalysts.
“So this rather small engineering staff actually enabled Feynman Dynamics to produce their catalyst at industrial scale.”
—Xu Hao, [09:18]
[10:00]
To reach gigaton impact, businesses must make green products as affordable as fossil-based ones—without relying solely on carbon pricing.
Example:
Yuan Chu uses CO₂ and waste calcium to produce high-quality calcium carbonate (used in paper, toothpaste, tires) cheaper than traditional methods.
"By using leftover calcium...Yuan Chu can actually produce high quality calcium carbonate cheaper than the conventional method..."
—Xu Hao, [10:43]
Example:
“The great news is...they already integrated many of their material into hundreds of thousands of mobile phones and sports cameras...”
—Xu Hao, [12:25]
[13:11]
Critical to rapid scaling: Get scientists, engineers, and business people in the same room early.
CarbonX program at Tencent as an example: Convening diverse stakeholders for constant feedback and productive (sometimes heated) debate.
“This is almost exactly what happened at CarbonX program...this productive dialogue...help speed up the process because it got everybody to thinking about everything at the same time, not waiting 200 years like alcohol now.”
—Xu Hao, [13:48]
[14:22]
“We already have lots of innovation in science, in engineering and business. And the secret to further accelerate the process is also simple: just do them all at once.”
—Xu Hao, [04:14]
“So it's not the science holding us up.”
—Xu Hao, [06:10]
“We simply couldn't wait that long. To tackle our climate challenge, we urgently need to speed up and scale up low carbon solutions.”
—Xu Hao, [03:30]
“Therefore, I'm definitely drunk on the possibility of a better and cleaner future. Cheers everyone. Thank you.”
—Xu Hao, [15:23]
Xu Hao’s talk is lively, optimistic, and pragmatic. He uses accessible analogies (“Lego blocks,” “fruit smoothie”) to demystify complex engineering and scientific issues, making the case that the barrier to climate progress isn’t scientific know-how but the speed and scale at which we unite and execute innovations across multiple domains.
Takeaway:
The science and engineering to achieve net-zero are largely here. Speed, scale, and cross-sector collaboration—right now—are the keys to making tomorrow’s world cleaner, better, and possibly, as Xu Hao says, “much better than what AI can generate for us today.”
