China plays a big role in the global push to shift from fossil fuels to cleaner energy. It's the world's largest carbon emitter but also a global leader in solar, wind, and battery technologies. This combination makes China a critical player in the energy transition. China may not be doing enough to reduce its own greenhouse gas emissions, but it is leading the way in producing low-cost, low-carbon solutions.

Why Materials Matter

One of the biggest challenges in switching to alternative energy is the need for specific materials like lithium, cobalt, and rare earth metals. These are essential for making things like solar panels, wind turbines, and batteries. In her report, "Minerals and Materials Challenges for Our Energy Future(s): Dateline 2024," Michelle Michot Foss emphasizes the critical role of materials in energy transitions:

"Energy transitions require materials transitions; sustainability is multifaceted; and innovation and growth will shape the future of energy and economies."

China controls much of the supply and processing of these materials. For example, it produces most of the world’s rare earth metals and has the largest capacity for making batteries. This gives China a big advantage but also creates risks. Michot Foss points out:

"China’s command over material supply chains presents both opportunities and risks. On one hand, it enables rapid scaling of technologies like wind, solar, and batteries. On the other hand, it exposes the global market to potential vulnerabilities, as geopolitical tensions and trade barriers could disrupt these critical flows."

China’s strategy for dominating alternative energy materials is also closely tied to its national security interests. By securing control over these critical supply chains, China not only hopes to guarantee its own energy independence but also gains significant geopolitical leverage.

“Is China’s leadership strategic or accidental? China’s dominance is a consequence of enormous excess materials supply chain and manufacturing capacity. A flood of exports are undermining materials and “green tech” businesses everywhere. It heightens vulnerabilities and geopolitical tensions. How do we in the US find our own comparative advantage?” Michot Foss notes that advanced materials should be a priority for US responses, especially as attention shifts to nuclear energy possibilities and as carbon capture and hydrogen initiatives play out.

Balancing Energy Growth and Emissions

GabrielCollins, in his report "Reality Is Setting In: Asian Countries to Lead Transitions in 2024 and 2025," offers another perspective. He focuses on how developing nations, especially in Asia, are shaping the energy transition:

"The developing world, including many countries in Asia, increasingly demand that developed nations’ policy advocacy stop treating the economic and environmental needs of the developing world as an afterthought."

Collins highlights China’s dual strategy: investing heavily in renewables while still using coal to meet its growing energy demand. He explains:

"China, which now has installed a terawatt combined of wind and solar capacity while still ramping up coal output and moving to dominate EV and renewables supply chains and manufacturing."

This strategy appeals to other developing nations, which face similar challenges of balancing energy needs with environmental goals while fostering economic growth and expanding industries.

The Numbers: Progress and Challenges

McKinsey’s Global Energy Perspective 2024 provides some useful data. On the bright side, China is installing renewable energy faster than any other country. In 2023, it added over 100 gigawatts of solar capacity, a world record. Wind energy is growing quickly too, and China leads in producing electric vehicle batteries.

But McKinsey also notes the challenges. Coal still generates more than half of China’s electricity. While renewable energy is growing fast, it’s not replacing coal yet—it’s just adding to China’s total energy capacity.

McKinsey sums it up: China is leading in renewable energy deployment, but its reliance on coal highlights the slow pace of deep decarbonization. The country is transitioning, but not fast enough to meet global climate targets.

Is China Leading or Lagging?

So, is China leading the energy transition? The answer is: it depends on how you define “leading.”

If leadership means building more solar and wind farms, dominating the materials supply chain, and being the leading supplier of low-carbon solutions, then yes, China is ahead of everyone else. But if leadership means cutting their own emissions quickly and shifting away from fossil fuels, China still has work to do.

China’s approach is practical. It’s making progress where it can—like scaling up renewables—but it’s also sticking with coal to ensure its economy and energy needs stay stable.

Final Thoughts

China is both a leader and a work in progress when it comes to the energy transition. Its achievements in renewable energy are impressive, but its reliance on coal and the challenges of balancing growth with sustainability show there’s still a long road ahead.

China’s story reminds us that the energy transition isn’t a straight path. It’s a journey full of trade-offs and complexities, and China’s experience reflects the challenges the whole world faces. At the same time, its focus on national security through energy independence and industrial strategy to build low-carbon export businesses signals a strategic move that is reshaping global power dynamics, leaving the United States and other nations to reevaluate their energy policies.

Houston energy innovator on why now's the right time for energy transition innovation

HOUSTON INNOVATORS PODCAST EPISODE 190

The cleantech innovation space has momentum, and Chevron strives to be one of the incumbent energy companies playing a role in that movement, Jim Gable, vice president of innovation at Chevron and president of Chevron Technology Ventures, shares on the Houston Innovators Podcast.

"People call it cleantech 2.0, but it's really cleantech 3.0," Gable says, explaining how he's been there for each wave of cleantech. "The people are better now — the entrepreneurs are better, the investors are better. Exits are here in the cleantech space."

"It's all driven by policy-enabled markets, and the policy is here now too. Twenty years ago, you didn't have nearly the same level of policy influence that you do now," he continues. "Things are coming together to help us really create and deliver that affordable, reliable, ever cleaner energy that's going to be needed for a long time."

Both CTV and Gable have been operating with this vision of cleaner, more reliable and affordable energy for over two decades. Gable, who's worked in various leadership roles across the company, returned to a job in the venture side of the business in 2021. He's officially relocated to Houston to lead CTV, which is based in the Ion.

CTV acts as Chevron's external innovation bridge, evaluating pitches from around 1,000 companies a year, funding and accelerating startups, working with internal teams to implement new tech, and more, as Gable explains. Under CTV's umbrella is the venture fund, the Catalyst Program, and the Chevron Studio, a newer initiative that matches entrepreneurs with technology research in order to take that tech to market.

"We say we open doors to the future within Chevron," he says on the show. "We're the onramp for early stage technology to get into the company."

Now that he's firmly planted in the Houston innovation ecosystem, Gable says is optimistic about the incumbents and the innovators coming together in Houston to forge the future of energy.

"I would just encourage Houston to not try to be something that we're not. Houston's got to be Houston, and I don't think we should try, necessarily, to follow the same path as Palo Alto or Boston," Gable says, adding that Houston's large and specialized energy sector is not a disadvantage. "We may not have the same breadth of primary research that other ecosystems have, and that's perfectly OK."

Gable shares more on his perspective of Houston's ecosystem and the energy transition as a whole on the podcast. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Rice research team's study keeps CO2-to-fuel devices running 50 times longer

new findings

In a new study published in the journal Science, a team of Rice University researchers shared findings on how acid bubbles can improve the stability of electrochemical devices that convert carbon dioxide into useful fuels and chemicals.

The team led by Rice associate professor Hoatian Wang addressed an issue in the performance and stability of CO2 reduction systems. The gas flow channels in the systems often clog due to salt buildup, reducing efficiency and causing the devices to fail prematurely after about 80 hours of operation.

“Salt precipitation blocks CO2 transport and floods the gas diffusion electrode, which leads to performance failure,” Wang said in a news release. “This typically happens within a few hundred hours, which is far from commercial viability.”

By using an acid-humidified CO2 technique, the team was able to extend the operational life of a CO2 reduction system more than 50-fold, demonstrating more than 4,500 hours of stable operation in a scaled-up reactor.

The Rice team made a simple swap with a significant impact. Instead of using water to humidify the CO2 gas input into the reactor, the team bubbled the gas through an acid solution such as hydrochloric, formic or acetic acid. This process made more soluble salt formations that did not crystallize or block the channels.

The process has major implications for an emerging green technology known as electrochemical CO2 reduction, or CO2RR, that transforms climate-warming CO2 into products like carbon monoxide, ethylene, or alcohols. The products can be further refined into fuels or feedstocks.

“Using the traditional method of water-humidified CO2 could lead to salt formation in the cathode gas flow channels,” Shaoyun Hao, postdoctoral research associate in chemical and biomolecular engineering at Rice and co-first author, explained in the news release. “We hypothesized — and confirmed — that acid vapor could dissolve the salt and convert the low solubility KHCO3 into salt with higher solubility, thus shifting the solubility balance just enough to avoid clogging without affecting catalyst performance.”

The Rice team believes the work can lead to more scalable CO2 electrolyzers, which is vital if the technology is to be deployed at industrial scales as part of carbon capture and utilization strategies. Since the approach itself is relatively simple, it could lead to a more cost-effective and efficient solution. It also worked well with multiple catalyst types, including zinc oxide, copper oxide and bismuth oxide, which are allo used to target different CO2RR products.

“Our method addresses a long-standing obstacle with a low-cost, easily implementable solution,” Ahmad Elgazzar, co-first author and graduate student in chemical and biomolecular engineering at Rice, added in the release. “It’s a step toward making carbon utilization technologies more commercially viable and more sustainable.”

A team led by Wang and in collaboration with researchers from the University of Houston also shared findings on salt precipitation buildup and CO2RR in a recent edition of the journal Nature Energy. Read more here.

The case for smarter CUI inspections in the energy sector

Guest Column

Corrosion under insulation (CUI) accounts for roughly 60% of pipeline leaks in the U.S. oil and gas sector. Yet many operators still rely on outdated inspection methods that are slow, risky, and economically unsustainable.

This year, widespread budget cuts and layoffs across the sector are forcing refineries to do more with less. Efficiency is no longer a goal; it’s a mandate. The challenge: how to maintain safety and reliability without overextending resources?

Fortunately, a new generation of technologies is gaining traction in the oil and gas industry, offering operators faster, safer, and more cost-effective ways to identify and mitigate CUI.

Hidden cost of corrosion

Corrosion is a pervasive threat, with CUI posing the greatest risk to refinery operations. Insulation conceals damage until it becomes severe, making detection difficult and ultimately leading to failure. NACE International estimates the annual cost of corrosion in the U.S. at $276 billion.

Compounding the issue is aging infrastructure: roughly half of the nation’s 2.6 million miles of pipeline are over 50 years old. Aging infrastructure increases the urgency and the cost of inspections.

So, the question is: Are we at a breaking point or an inflection point? The answer depends largely on how quickly the industry can move beyond inspection methods that no longer match today's operational or economic realities.

Legacy methods such as insulation stripping, scaffolding, and manual NDT are slow, hazardous, and offer incomplete coverage. With maintenance budgets tightening, these methods are no longer viable.

Why traditional inspection falls short

Without question, what worked 50 years ago no longer works today. Traditional inspection methods are slow, siloed, and dangerously incomplete.

Insulation removal:

Disruptive and expensive.
Labor-intensive and time-consuming, with a high risk of process upsets and insulation damage.
Limited coverage. Often targets a small percentage of piping, leaving large areas unchecked.
Health risks: Exposes workers to hazardous materials such as asbestos or fiberglass.

Rope access and scaffolding:

Safety hazards. Falls from height remain a leading cause of injury.
Restricted time and access. Weather, fatigue, and complex layouts limit coverage and effectiveness.
High coordination costs. Multiple contractors, complex scheduling, and oversight, which require continuous monitoring, documentation, and compliance assurance across vendors and protocols drive up costs.

Spot checks:

Low detection probability. Random sampling often fails to detect localized corrosion.
Data gaps. Paper records and inconsistent methods hinder lifecycle asset planning.
Reactive, not proactive: Problems are often discovered late after damage has already occurred.

A smarter way forward

While traditional NDT methods for CUI like Pulsed Eddy Current (PEC) and Real-Time Radiography (RTR) remain valuable, the addition of robotic systems, sensors, and AI are transforming CUI inspection.

Robotic systems, sensors, and AI are reshaping how CUI inspections are conducted, reducing reliance on manual labor and enabling broader, data-rich asset visibility for better planning and decision-making.

ARIX Technologies, for example, introduced pipe-climbing robotic systems capable of full-coverage inspections of insulated pipes without the need for insulation removal. Venus, ARIX’s pipe-climbing robot, delivers full 360° CUI data across both vertical and horizontal pipe circuits — without magnets, scaffolding, or insulation removal. It captures high-resolution visuals and Pulsed Eddy Current (PEC) data simultaneously, allowing operators to review inspection video and analyze corrosion insights in one integrated workflow. This streamlines data collection, speeds up analysis, and keeps personnel out of hazardous zones — making inspections faster, safer, and far more actionable.

These integrated technology platforms are driving measurable gains:

Autonomous grid scanning: Delivers structured, repeatable coverage across pipe surfaces for greater inspection consistency.
Integrated inspection portal: Combines PEC, RTR, and video into a unified 3D visualization, streamlining analysis across inspection teams.
Actionable insights: Enables more confident planning and risk forecasting through digital, shareable data—not siloed or static.

Real-world results

Petromax Refining adopted ARIX’s robotic inspection systems to modernize its CUI inspections, and its results were substantial and measurable:

Inspection time dropped from nine months to 39 days.
Costs were cut by 63% compared to traditional methods.
Scaffolding was minimized 99%, reducing hazardous risks and labor demands.
Data accuracy improved, supporting more innovative maintenance planning.

Why the time is now

Energy operators face mounting pressure from all sides: aging infrastructure, constrained budgets, rising safety risks, and growing ESG expectations.

In the U.S., downstream operators are increasingly piloting drone and crawler solutions to automate inspection rounds in refineries, tank farms, and pipelines. Over 92% of oil and gas companies report that they are investing in AI or robotic technologies or have plans to invest soon to modernize operations.

The tools are here. The data is here. Smarter inspection is no longer aspirational — it’s operational. The case has been made. Petromax and others are showing what’s possible. Smarter inspection is no longer a leap but a step forward.

Scientists warn greenhouse gas accumulation is accelerating and more extreme weather will come

Climate Report

Humans are on track to release so much greenhouse gas in less than three years that a key threshold for limiting global warming will be nearly unavoidable, according to a study released June 19.

The report predicts that society will have emitted enough carbon dioxide by early 2028 that crossing an important long-term temperature boundary will be more likely than not. The scientists calculate that by that point there will be enough of the heat-trapping gas in the atmosphere to create a 50-50 chance or greater that the world will be locked in to 1.5 degrees Celsius (2.7 degrees Fahrenheit) of long-term warming since preindustrial times. That level of gas accumulation, which comes from the burning of fuels like gasoline, oil and coal, is sooner than the same group of 60 international scientists calculated in a study last year.

“Things aren’t just getting worse. They’re getting worse faster,” said study co-author Zeke Hausfather of the tech firm Stripe and the climate monitoring group Berkeley Earth. “We’re actively moving in the wrong direction in a critical period of time that we would need to meet our most ambitious climate goals. Some reports, there’s a silver lining. I don’t think there really is one in this one.”

That 1.5 goal, first set in the 2015 Paris agreement, has been a cornerstone of international efforts to curb worsening climate change. Scientists say crossing that limit would mean worse heat waves and droughts, bigger storms and sea-level rise that could imperil small island nations. Over the last 150 years, scientists have established a direct correlation between the release of certain levels of carbon dioxide, along with other greenhouse gases like methane, and specific increases in global temperatures.

In Thursday's Indicators of Global Climate Change report, researchers calculated that society can spew only 143 billion more tons (130 billion metric tons) of carbon dioxide before the 1.5 limit becomes technically inevitable. The world is producing 46 billion tons (42 billion metric tons) a year, so that inevitability should hit around February 2028 because the report is measured from the start of this year, the scientists wrote. The world now stands at about 1.24 degrees Celsius (2.23 degrees Fahrenheit) of long-term warming since preindustrial times, the report said.

Earth's energy imbalance

The report, which was published in the journal Earth System Science Data, shows that the rate of human-caused warming per decade has increased to nearly half a degree (0.27 degrees Celsius) per decade, Hausfather said. And the imbalance between the heat Earth absorbs from the sun and the amount it radiates out to space, a key climate change signal, is accelerating, the report said.

“It's quite a depressing picture unfortunately, where if you look across the indicators, we find that records are really being broken everywhere,” said lead author Piers Forster, director of the Priestley Centre for Climate Futures at the University of Leeds in England. “I can't conceive of a situation where we can really avoid passing 1.5 degrees of very long-term temperature change.”

The increase in emissions from fossil-fuel burning is the main driver. But reduced particle pollution, which includes soot and smog, is another factor because those particles had a cooling effect that masked even more warming from appearing, scientists said. Changes in clouds also factor in. That all shows up in Earth’s energy imbalance, which is now 25% higher than it was just a decade or so ago, Forster said.

Earth’s energy imbalance “is the most important measure of the amount of heat being trapped in the system,” Hausfather said.

Earth keeps absorbing more and more heat than it releases. “It is very clearly accelerating. It’s worrisome,” he said.

Crossing the temperature limit

The planet temporarily passed the key 1.5 limit last year. The world hit 1.52 degrees Celsius (2.74 degrees Fahrenheit) of warming since preindustrial times for an entire year in 2024, but the Paris threshold is meant to be measured over a longer period, usually considered 20 years. Still, the globe could reach that long-term threshold in the next few years even if individual years haven't consistently hit that mark, because of how the Earth's carbon cycle works.

That 1.5 is “a clear limit, a political limit for which countries have decided that beyond which the impact of climate change would be unacceptable to their societies,” said study co-author Joeri Rogelj, a climate scientist at Imperial College London.

The mark is so important because once it is crossed, many small island nations could eventually disappear because of sea level rise, and scientific evidence shows that the impacts become particularly extreme beyond that level, especially hurting poor and vulnerable populations, he said. He added that efforts to curb emissions and the impacts of climate change must continue even if the 1.5 degree threshold is exceeded.

Crossing the threshold "means increasingly more frequent and severe climate extremes of the type we are now seeing all too often in the U.S. and around the world — unprecedented heat waves, extreme hot drought, extreme rainfall events, and bigger storms,” said University of Michigan environment school dean Jonathan Overpeck, who wasn't part of the study.

Andrew Dessler, a Texas A&M University climate scientist who wasn't part of the study, said the 1.5 goal was aspirational and not realistic, so people shouldn’t focus on that particular threshold.

“Missing it does not mean the end of the world,” Dessler said in an email, though he agreed that “each tenth of a degree of warming will bring increasingly worse impacts.”
