Nanotechnology & Environmental Benefits

Make the Environment Sustainable through Nanotechnology

Present Challenges:

The subject of ‘Global Warming’ itself is generating a lot of heat now a days. Having struggled with the issue of ozone layer depletion in the last decades, the world is now facing the challenge of global warming and resultant climate change. It is said ‘environment is not what we inherit from our ancestors, we borrow it from our future generations.’ We have already started facing the consequences of reckless use of natural resources leading to ecological imbalance. Thus, to hand over to our future generations the same level of environmental quality which we are presently enjoying is becoming difficult day be day. This makes the issue of environmental sustainability more important than it ever was.

Our Strategic Applications in Nano Science

The brighter spot is that quite a lot of awareness is being created on environmental issues the world over. The world has realized that it is the high time that we resort to discriminate the use of natural resources and try for lower contamination. People and organizations are addressing pressing energy and environmental needs by deploying renewable energy sources, switching to energy efficient and less polluting ways of production, finding alternatives ensuring lesser need of raw materials for the same quantum of production, etc. Nanotechnology applications can reduce the environmental problems substantially with their targeted and indirect interventions. Nanotechnology has the potential to change the way the things are produced and processed and to further reduce their hazardous side and after effects. More

Nanotechnology in India: Case Study of Environmental Issues

India is still on the first middle side of the Kuznets curve. At this position, both the income inequalities and the environmental problems are acute. By the time India becomes a developed economy; both these problems, particularly the environmental, are expected to settle. Kuznets curve underlines that the more developed an economy is, the cleaner it becomes. Regarding the things needed badly in the Indian economy to achieve that level of development, energy finds a prime place. Nanotechnology has the potential to facilitate energy production in a much cleaner and renewable way. Quite a few emerging renewable energy developments are coming with the integration of the science and technology of energy generation and that of the nano science and nanotechnology. From solar cell and fuel cell fabrication to energy management, transmission, conservation and savings the applications of nanoscience offer a range of opportunities. Clean energy is becoming a mainstream business.

Nanotechnology & Environmental Management

Challenges	How Nanotechnology helps
Cleaner conventional energy	Production of electricity from coal or natural gas can be made more efficient by strategic use nanotechnology in turbine plants In nuclear energy, nanotechnology can help improve the radiation resistance of the materials
Dependable supply of renewable energy at affordable cost. The two big complaints against solar and wind power are high cost and intermittent supply as large scale storage not possible	Use of nanotechnology in chemical reactions could provide hydrogen for tomorrow's fuel-cell powered vehicles Cells with nano-crystalline coatings of metal oxides enable production of hydrogen gas directly from sunlight Nano structured turbines ensure efficient production of wind energy at lower cost Nano based solar cell and panels contribute a lot for efficient generation and transmission of solar power More details in section on solar The batteries currently available are not suitable for large scale storage. Strategic applications of nanoscience will help in creating large banks of batteries to make storage on large scale possible Nanotechnology would also enable creating new kind of nano tubes based capacitors which make batteries usable for indefinite period
Safe and large scale storage of hydrogen energy. Conventional technology stores hydrogen in high pressure tanks which is highly unsafe	Nanotechnology offers safe and practicable solutions like absorption onto high surface area solids and use of carbon nano tubes and nano structured graphite fibres for combining with metal hydride compounds
Fuel cell usage has been limited due to material performance and high cost since it needs platinum which is scarcely available	Nanoscale material can replace platinum completely or partially with increased efficiency for specific applications Carbon nanotubes could enable a substantial improvement in the performance of fuel cells, together with a heavy cost reduction of catalyst material
Developing efficient transmission devices	Nano engineering could lead to smart devices like smart windows, energy efficient LEDs and wireless controls and also highly efficient conductors and superconductors that could eventually replace current transmission facilities. Strategic use of nanostructures would make any device energy efficient
Developing energy efficient distribution networks	Nano-enabled capacitors will create entirely new networks for local electricity storage which could ensure much lower rates of energy wastage and improved performance
Addressing the issues of soil, water and air pollution through strategic applications of nanoscience	Pollution monitoring using nanosensors Lower energy needs due to lightweight strong materials Products with molecular-level precision through the use of productive nano systems, could result in virtually no chemical waste Nanoenabled products like nanowire based paper can cleanup oil and other organic pollutants Nano-sized particles of iron are useful for cleaning up contaminants in groundwater, soil and sediments
New possibilities through Nanotechnology	Personal power-jackets that could use heat from the human body to recharge cell-phones and other electronic devices Microbial fuel cells where an organism performs electron transfer mechanism are being developed through use of nanotechnology High powered batteries that can be used in electric vehicles are being developed by strategic applications of nanoscience

What SAiNSCE does?

India offers a very good potential for renewable energy. The region from where SAiNSCE operates, in particular, is geographically favorable for solar and wind installations because of a long coastline and high solar radiation. The region also has plans to develop itself as a hub of this non-conventional energy. Thus SAiNSCE strategically placed to venture into the sector of renewable energy.
Better life and cleaner environment being our motto, SAiNSCE is networking with the stakeholders for commercialization of nanotechnology applications for production, transmission and conservation of clean energy. It is also aggressively working for creating awareness among the stakeholders towards this issue through various forums. We believe that cleaner energy through applications of nanoscience will benefit the society both of today and the future and will of course create business opportunities for the ventures involved in this sector.

What Is SAiNSCE planning next:

SAiNSCE has already started tying up marketing of solar Nanotechnology devices in the Indian market. Very shortly, it plans to take up manufacture of nano enabled energy devices particularly in the solar field. Also, through our initiatives in water and other sectors, we are committed to offer a qualitative service in the environmental field.
