CO2 capture is a collection of technologies that can minimize CO2 emission generated from manmade sources such as burning fossil fuels before it is released to the atmosphere. Scientists are also considering direct air capture (DAC) where CO2 can be removed from the air using a series of chemical or physical process.

Fossil fuel-related carbon emission, especially in the power plants, takes the main part in overall CO2 emission, and thus two key carbon capture technologies (pre-combustion and post-combustion) are being developed. In addition, various sectors of economy such as agriculture and chemical industry release CO2 to the air significantly, and thus CO2 capture technologies tailored for these areas are also needed.

Hydrogen is an ideal clean energy source because its sole product after combustion is H2O and no greenhouse gases or environmentally harmful compounds are released. H2 is of particular interests in automotive applications because it is a zero-emission fuel, abundantly available, and, when liquefied, has triple the energy density of gasoline. A full system based on H2 involves its production, delivery, and storage, as well as the fuel cell technology. Among them, H2 storage play a key role in this development.

The inherent volatility of H2 at ambient conditions poses significant challenges for its physical storage in pressurized tanks, which typically offer only modest volumetric energy densities. To enhance the practicality of H2 as a fuel for daily use, there is a pressing need for the development of low-cost, lightweight materials that are capable of reversible hydrogen uptake and storage densities greater than that of liquid hydrogen.

Agrochemistry is a branch of chemistry that focuses on the study and application of chemical processes and products in agriculture. This field encompasses a wide range of topics, including the development and use of fertilizers, pesticides, herbicides, and plant growth controllers to enhance crop production and protect plants from pests and diseases. Agrochemists work to understand the interactions between these chemicals and the environment, aiming to improve the efficiency and sustainability of agricultural practices. By studying the chemical properties and reactions of substances used in farming, agrochemistry helps optimize the growth and health of crops while minimizing the negative impacts on the ecosystem.

Agrochemistry integrates principles from organic chemistry, biochemistry, and environmental science to develop innovative solutions for the agricultural industry. By advancing the understanding of how chemical inputs affect agricultural systems, agrochemistry plays a crucial role in meeting the growing global demand for food in a sustainable and environmentally responsible manner.
