Carbon capture and storage (CCS) systems are a promising technology for reducing carbon dioxide (CO2) emissions from power plants and industrial facilities. CO2 is one of the main greenhouse gases responsible for global warming, and reducing emissions from these sources is crucial for achieving global climate goals.

There are two main types of carbon capture systems: post-combustion and pre-combustion. Post-combustion capture involves capturing CO2 after it has been released from the combustion process, while pre-combustion capture captures CO2 before it is released.

Post-combustion capture systems use various technologies, such as amine solvents, to capture CO2 from the flue gas produced by power plants and industrial facilities. The captured CO2 is then compressed and transported to a storage site, typically an underground geological formation. One of the main advantages of post-combustion capture is that it can be retrofitted to existing power plants, allowing for a relatively quick deployment of the technology.

Pre-combustion capture systems, on the other hand, capture CO2 before it is released by converting fossil fuels into a mixture of hydrogen and CO2. The CO2 is then separated and captured, while the hydrogen is used as a fuel. Pre-combustion capture systems are typically more efficient than post-combustion systems, but they require the construction of new power plants or the retrofitting of existing ones.

The cost of carbon capture is a major barrier to the widespread deployment of the technology. However, costs have been decreasing in recent years, and it is expected that they will continue to decrease as the technology is further developed and deployed. Additionally, government policies, such as carbon pricing and subsidies, can help to reduce costs and encourage the deployment of carbon capture systems.

A recent breakthrough post-combustion carbon capture system unveiled by the researchers from the Pacific Northwest National Laboratory promises to cut those costs significantly by converting the captured carbon into methanol. Methanol being one of the most produced chemicals in the world, utilized in the production of many everyday items such as plastics, paints, construction materials and biofuels.

The sales from the created methanol can generate meaningful revenues for power plants, further decreasing the costs of running carbon capture systems. PNNL scientists believe that this form of carbon recycling, can boost the development and adoption of CCS around the world. The new system is intended to work with the flue gas emitted by coal, gas and, biomass power plants.

Innovation in the carbon capture sector is essential in the fight against climate change. The International Energy Agency (IEA) estimates that CCS could reduce CO2 emissions by up to 10 Gt by 2050, which is equivalent to about one-fifth of the total emissions reduction needed to meet the Paris Agreement targets.

The new carbon capture system created by Pacific Northwest National Laboratory researchers is a promising technology that could play a vital role in the fight against climate change. Its high selectivity, stability, and lower cost of production make it an attractive option for large-scale carbon capture and storage. With further research and development, this technology could become a vital tool in the effort to reduce carbon emissions and slow down the effects of global warming.

Smart Cities

Reading Time: 2 minutesIn order to overcome the increasing problems of urbanization, a smart city is a structure consisting primarily of ICTs to create, implement and promote sustainable development activities.

In fact, the intelligent network of linked objects and computers that relay data using wireless technologies and the cloud is an integral aspect of this ICT scheme.

Using laptops and handheld computers as well as wired vehicles and homes, individuals interact with smart city environments in various ways. Pairing sensors and information with the physical infrastructure and facilities of a city will lower costs and promote resilience.


Why do we need smart cities?

Urbanization is a non-ending phenomenon. Today, 54% of people worldwide live in cities, a proportion that’s expected to reach 66% by 2050. Combined with the overall population growth, urbanization will add another 2.5 billion people to cities over the next three decades.

Environmental, social, and economic sustainability is a must to keep pace with this rapid expansion that is taxing our cities’ resources.


Copenhagen is a smart city!

A public-private partnership, ProjectZero, has been developed to encourage and support the transition of Sonderborg into a ZEROcarbon society by 2029, focusing on infrastructure, transport, urban energy supply and data/ICT. Carbon-free development and progressive urbanization have been accomplished from the early planning level to the implementation process, relying on the active participation of residents.A core goal of ProjectZero is the provision of education at all levels. People are studying how green approaches, from Kindergarten to PhD, will help them to co-create a new world. The city’s happiness is reflected explicitly in the constructive interaction between individuals. In rural areas, private homes are being upgraded with electricity, linked to green district heating, and the use of heat pumps is increasing dramatically.Trained local banks, craftsmen and real estate agents support the citizens’ green journey by offering competitive services and solutions. The journey often starts with shifting to inexpensive LED-bulbs and biking to work. Professional municipal banks, craftsmen and real estate brokers promote the green path of individuals by offering competitive instruments and tactics. The journey also begins by switching and cycling to work to cheap LED-bulbs.
