Impact on Sustainability:
How Are We Going to Manage Water?
-
Efficient Water Filtration: Due to its unique molecular structure and small pore size, graphene can act as an extremely efficient filter. It can remove impurities and contaminants from water, including heavy metals, bacteria, and other pathogens, more effectively than traditional filtration methods. The implementation of graphene-based water filtration systems could potentially benefit millions of people worldwide, especially in regions where access to clean water is limited. According to the World Health Organization, approximately 2.2 billion people lack access to safely managed drinking water services. Graphene filtration, given its high efficiency, could be a viable solution for these populations. Imagine you are on a farm in a municipality in the mountains of Colombia or in a large city; both scenarios benefit from graphene filtration.
-
Desalination: Graphene has the potential to revolutionize the desalination process, converting seawater into drinking water. Its ability to allow water molecules to pass through while blocking salts and other contaminants can make desalination more energy-efficient and accessible. Graphene desalination technology could be particularly beneficial for coastal cities and island nations where freshwater is scarce. These regions, which often rely on costly water imports or energy-intensive desalination processes, could use graphene technology to obtain freshwater more sustainably and economically. Imagine Santa Marta or Cartagena.
-
Detection and Removal of Contaminants: In addition to filtration, graphene can be used to detect various contaminants in water. This is crucial for the rapid identification and elimination of toxic or hazardous substances before the water reaches consumers. The ability of graphene to detect and remove contaminants from water can have a direct impact on public health, especially in urban areas where water pollution is a significant issue. By ensuring a cleaner and safer water supply, graphene can help reduce the incidence of water-related diseases and improve overall quality of life.

The efficient use of filtered or desalinated water can help arid or water-scarce regions to farm more sustainably, increasing food security and supporting local economies. Climate change is altering precipitation patterns and increasing the frequency of extreme events such as droughts and floods. Efficient water management helps farmers adapt to these changes, ensuring a more consistent and reliable water supply for crops. Imagine this in coffee cultivation.
How Are We Going to Manage Energy?

Due to its high conductivity and transparency, it allows for the creation of solar panels that are both more effective in capturing sunlight and more durable. This can lead to a reduction in the cost of solar energy and make it more accessible. Graphene is expected to increase the efficiency of solar panels beyond the current 20-25% of silicon panels. This could mean a reduction in the cost of solar energy and greater accessibility, potentially benefiting millions of people worldwide, especially in regions with high solar irradiation. Imagine you are in Barranquilla or Cali and you install a solar panel on your roof to save on your electricity bill and perhaps even make money with the energy you produce.

Batteries incorporating graphene can charge faster, last longer, and have a higher storage capacity compared to traditional lithium-ion batteries. Graphene batteries can charge up to five times faster than conventional lithium-ion batteries. This is crucial for the widespread adoption of electric vehicles and renewable energy storage, positively impacting the reduction of fossil fuel dependence.
-
Efficient Superconductors: Graphene has also shown superconducting properties, which could be used to develop more efficient energy transmission systems, reducing energy loss in power grids. Although still experimental, graphene could increase the efficiency of energy transmission, reducing losses that can currently be up to 10% in power grids.
-
Improved Electric Vehicles: In the transportation sector, graphene can contribute to the manufacture of more efficient electric vehicles. Its use in electric vehicle batteries could increase their range and decrease charging times, making them more practical for daily use. Potential increase in electric vehicle range by up to 50-100% compared to conventional batteries. This could accelerate the transition to electric vehicles, significantly reducing greenhouse gas emissions.
