Chinese scientists and engineers have announced an innovative new plan for addressing climate change via net-negative GHG emissions. This new process, named Electrified Dry Reforming of Methane (e-DRM), enables a highly efficient conversion of problematic carbon dioxide (CO2) and methane (CH4) into valuable syngas. It additionally sequesters more greenhouse gases than it emits. 3D reconstruction with neural networks In these Bionic Smart Robots, the research team led by Prof. Professors Zhang Jian and Zhang Yexin took the project forward, working closely with Professor Zhang Zhaoliang from University of Jinan.
CO2 and CH4 together account for at least 95% of the total warming that humans have caused. We need to get smart on reducing these emissions fast—today more than ever. The e-DRM process responds to this urgent need and promises to create useful and beneficial resources.
The E-DRM Process
In the e-DRM process, a catalyst deposited on activated carbon is utilized to drive the conversion of greenhouse gases. More specifically, this catalyst is Ni-La2O3-loaded activated carbon. This collaborative and cutting-edge approach simultaneously removes CO2 while capturing the climate impact of CH4. It subsequently gasifies them into syngas, an essential feedstock for manufacturing high-value chemicals including methanol and ammonia.
One of the most impressive aspects of e-DRM is its ability to bring about thermodynamic equilibrium conversion. This equilibrium is held for more than 120 hours, demonstrating the stability of this process. Among these, the e-DRM strategy dramatically increases the energy efficiency to a record high of 2.976 mmol/kJ. It has a stellar energy use efficiency of 80%. These metrics show how successful it has been at reducing energy waste while increasing production.

Environmental Impact
This importance of achieving net-negative emissions cannot be overstated in the overall fight against climate change. In fact, the e-DRM process sequesters more greenhouse gases than it emits. Together, these make a powerful case for a new solution to help bring down atmospheric CO2 levels. Countries are racing to fulfill climate commitments. Technologies such as e-DRM thus can serve a pivotal role in the fight against global warming.
As detailed in a study released today by the research team in the journal Science Advances, they emphasize their most exciting potential applications, which extend beyond simply reducing emissions. Through this e-DRM process, the resulting syngas can then fuel a range of beneficial industrial applications. This sustainable innovation is creating the foundation for a cleaner, circular economy that keeps natural resources in use longer.
Future Prospects
Nevertheless, global focus is quickly moving in the direction of climate change adaptation strategies. In this context, the introduction of e-DRM represents a great step forward in electrified catalysis. Researchers stress that reams of new studies will be needed to perfect the process even further and test its commercial applicability.
This cooperation between NIMTE and the University of Jinan has proved to be tremendously fruitful. It shows the importance of interdisciplinary approaches to advancing complex environmental challenges. These institutions are using their unique and collective expertise. They are creating new pathways that will enable more creative solutions to transform our industries and turbocharge a clean, equitable economy.
