Saudi Scientists From KAUST Find New Way To Store CO2
The new method for storing and transporting carbon dioxide in solid form could have a huge impact in fighting climate change.
Scientists from Saudi Arabia’s King Abdullah University of Science and Technology (KAUST) have discovered a novel way to store and transport CO2 in the form of a powder.
The breakthrough discovery was made by a team of scientists led by Professor Cafer T. Yavuz of KAUST. The researchers created a mesh-like clathrate structure, which can physically trap molecules of one component within the crystal structure of another.
This clathrate structure proved to be a more energy-efficient way to trap and store greenhouse gasses, as it requires no refrigeration, making it much more energy efficient than current systems.

“Our team made it possible to carry CO2 in a solid form without the need for refrigeration or pressure. You will be able to literally shovel CO2-loaded solids from now on,” explained Professor Yavuz. “The impact is wide and strong, as the global fuel industry and the kingdom entities are actively looking for ways to capture, store and transport CO2 without significant energy penalties”.

Lebanon Ministers Meet Visa Over National Digital Payment Platform
Finance and technology ministers say a comparative study and roadmap will follow before any decision on adopting a model.
Lebanon’s finance and technology ministers met representatives from Visa last week to discuss a proposed unified national digital payment platform for government services, according to a readout from the Ministry of Finance.
The meeting brought together Finance Minister Yassin Jaber, Minister of State for Technology and Artificial Intelligence Kamal Shehadeh, a Visa delegation, and experts from both ministries. Discussion focused on whether Lebanon could establish a single platform through which citizens and institutions would pay taxes, fees, fines and other official transactions electronically, using mobile phones and other digital channels.
The Visa delegation presented examples from countries that have adopted unified government payment platforms, including the United Arab Emirates, Singapore, Estonia and Jordan. According to the readout, the examples were presented as having increased collection rates and expanded financial inclusion.
Talks covered settlement mechanisms, direct transfer to the treasury account, financial reconciliation, risk management, cybersecurity, fees, and an operational model that would involve the private sector. The parties agreed to continue technical and institutional consultations, prepare a comparative study, and develop an implementation roadmap before any decision on adopting a model for Lebanon.
Jaber said the Ministry of Finance had already enabled citizens to pay using credit cards and e-wallets through transfer companies, but described the proposed platform as a further step. He framed the development of electronic payment and collection systems as a priority within the ministry’s modernization plan.

Shehadeh outlined the citizen-facing concept as a single mobile application through which users could settle obligations to ministries, government institutions and other bodies.
“The idea, in short, is that any citizen downloads an application on their mobile phone, through which they can pay all service obligations for all ministries, government institutions, or those owned by the Lebanese state, and others as well, as the platform is not limited only to state institutions,” he said.
Shehadeh added that the platform would not displace banks and money transfer companies that currently provide collection services to the state, calling it complementary to their work.
