Our Work

The School of Energy and Environment at DIAT is dedicated to advanced research and development in areas related to energy and sustainability. One of the key focuses of the school is the development of safe hydrogen, a critical component in the shift towards a more sustainable energy economy. Additionally, the school is involved in the R&D of new ionic liquids, which have a wide range of potential applications in areas such as energy storage and chemical processing. Thermal energy storage materials are also an area of work, with research aimed at developing new materials that can efficiently store and release thermal energy, also the school is engaged in developing new photocatalytic materials, which have the potential to play a key role in a wide range of applications, from water purification to production of renewable fuels.

Development of Safe Hydrogen

The world's energy demand is continuously increasing, and conventional energy sources are limited, non-renewable and create large amounts of pollutants. Due to the reduction of fossil fuels and pollution concerns, renewable and clean energy sources are required. Hydrogen gas is considered a promising energy carrier due to its pollution-free combustion and easy production. However, there are safety concerns regarding the handling and storage of hydrogen, such as its tendency to leak during storage due to its low molecular size, embrittlement of metals, high flammability and explosive range, and low ignition energy. Hydrogen burns with a nearly invisible flame, making it difficult to prevent and poses significant safety hazards. As a result, the investigation aims to suppress or inhibit hydrogen flames by adding suppressors to improve the safety of hydrogen technology. The inhibited hydrogen could be useful in reducing current hydrogen safety challenges and expanding the use of hydrogen in various applications, such as fuel transportation, industrial use, and onboard fire prevention and safety.

Energy Storage Materials

Energy storage materials play a crucial role in addressing the energy and environmental challenges of the present time. These materials enable the integration of renewable energy sources into the grid, allowing excess energy to be stored and used when needed. This helps to reduce our reliance on fossil fuels, lower greenhouse gas emissions, and mitigate the impacts of climate change. However, the manufacturing, use, and disposal of energy storage materials also have environmental impacts, and their lifecycle analysis must be considered. Therefore, the development of energy storage materials based on thermal energy that is not only efficient but also sustainable and environmentally friendly is a critical area of research and development.

Photocatalysis for green hydrogen generation

Photocatalysis is a promising technology for the green generation of hydrogen, which has significant potential as a clean energy carrier. Photocatalysis involves the use of a catalyst and light to drive chemical reactions that produce hydrogen from water. This process is renewable and sustainable, and it produces no greenhouse gas emissions or other harmful pollutants. In addition to its energy benefits, photocatalysis can also help to address environmental challenges such as water scarcity and pollution, as it can use wastewater as a source of hydrogen production. While there are still some challenges to be overcome in terms of scaling up and optimizing photocatalysis for commercial use, it holds great promise as a green and sustainable solution for hydrogen generation.

Preparation and Applications of green solvents

Ionic liquids are typical green solvent that has gained attention in recent years due to their unique properties and potential applications in the energy and environmental fields. They are non-volatile, non-flammable, and have negligible vapor pressure, making them more environmentally friendly than traditional organic solvents. Ionic liquids have been studied for their potential in energy storage and conversion, as well as in the removal of pollutants from air and water. They can also be used in the development of new materials, such as supercapacitors and solar cells. Overall, this research has the potential to contribute to the development of sustainable energy and environmental solutions.

Separation of Carbon dioxide

Separation of CO2 is an important process in mitigating the effects of greenhouse gas emissions on the environment. However, the process of separating CO2 can be energy-intensive and therefore contribute to carbon emissions if not done in a sustainable manner. There are various technologies available for CO2 separation, including absorption, adsorption, and membrane separation, each with its own energy requirements and environmental impacts. The choice of technology and the energy source used to power the separation process can greatly affect the overall environmental impact of CO2 separation. Therefore, careful consideration of energy and environmental factors is necessary when implementing CO2 separation technologies and the research is focused on the same.

Membranes for Wastewater Treartment

Membrane technology has emerged as a promising approach for wastewater treatment due to its ability to remove a wide range of contaminants while consuming less energy than traditional treatment methods. Membrane-based wastewater treatment systems can operate at low pressures, reducing energy consumption and associated carbon emissions. However, the production of membranes and their disposal at the end of their life cycle can have environmental impacts, particularly if they are not properly managed. The choice of membrane material can also impact the energy and environmental footprint of the treatment process. Therefore, a holistic evaluation of the energy and environmental impacts of membrane-based wastewater treatment systems is necessary for sustainable implementation.

Reclamation of Precious Metals

Efficient reclamation of precious metals, particularly lithium or tungsten or titanium, from end-of-life products and waste streams is important for both environmental and economic reasons. Lithium is a key component of rechargeable batteries used in electric vehicles and renewable energy storage systems. The reclamation of lithium from waste streams can reduce the reliance on virgin materials and reduce the carbon footprint associated with their extraction and production. However, the energy required for the reclamation process and the potential environmental impacts associated with the treatment of waste streams need to be carefully considered to ensure the overall sustainability of the process. Therefore, the development of efficient and environmentally friendly reclamation technologies is crucial for the future of lithium and other precious metals.

Gas Recovery from Methane Hydrates

To tackle the ever-increasing need of energy in the world, it is important to continuously identify new energy sources. Methane hydrates are ice like crystalline compounds primarily located in seabed and permafrost regions. Due to high amount of natural gas trapped within crystals of these hydrates, they pose as a promising energy resource. The major challenge lies in the recovery of methane gas from the hydrates. Release of methane gas from hydrate require disturbing the methane hydrate equilibrium state either by depressurization or by thermal stimulation. Microwave heating has proved to increase the gas recovery from the hydrates, however, research and development in this area is quite prominent before qualifying for a pilot trial. Continuous recovery of methane from hydrates leads to stability problems with the seabed, which can be catastrophic in nature leading to major earthquakes or Tsunami. Therefore, it is also important to have a good assessment of sustainability of any hydrate reservoir. New innovations are needed and are important to be successfully able to dissociate the hydrate and manage the methane gas for energy usage

Hydrogen Fueling and Storage

Hydrogen is becoming the center of attraction for the modern-day automotive systems, particularly due to its easy availability and versatility. At the center of all the development in line with hydrogen economy lies the fueling and storage of hydrogen. Much of the research is needed in direction of how to replace the traditional gas/liquid fuel filling stations by hydrogen fueling stations. The challenges exist for making the fueling experience for consumers as easy as it is with traditional fuels. Furthermore, the thermodynamics of filling process, and physical and chemical nature of hydrogen put certain restriction on hydrogen filling. Society of Automotive Engineers (SAE) has led down certain norms for safe hydrogen filling through these stations. However, for practical and economical purposes and for optimized filling experience, much research is needed in effectively adapting and analyzing these norms for local conditions. The storage of hydrogen also proposes certain challenges in terms of hydrogen embrittlement, storage space, thermodynamic and physical conditions, and usability of hydrogen as fuel.

Bio-Diesel in Combustion Engines

Fossil fuels are going to be exhausted in near future. A suitable fuel alternative for transportation and mobility industry is a need of the time. Non-edible oils are present in abundance and can be used as a fuel in combustion engines after processing. Pongamia Pinnata is bio-diesel produced through the transesterification process. This bio-diesel is a good quality fuel which has superior calorific value, lower density and viscosity and combustion properties. They produce less environmental pollution and contribute to energy security and safety of country.
