Recommendations of the “International Council of Academies of Engineering and Technological Sciences” (CAETS-2015) summit on -“ Pathways to sustainability for Energy, Mobility and Healthcare Engineering”, held from 13th to 15th Oct, are ready to be submitted to respective governments.
The 3-day technical deliberations of eminent international experts in Energy, Mobility and Healthcare Engineering from Belgium, Canada, China, France, Germany, Hungary, India, Japan, Netherlands, South Africa, Spain, Sweden, Switzerland, UK, USA, Uruguay etc were summarised by CAETS CONVOCATION-2015”, to frame these recommendations.
In India they will be submitted by the Indian National Academy of Engineering (INAE) to the Government.
Achieving long term sustainability, under business as usual mode, is a major technological challenge in energy, mobility and health care sectors.
Minister of Science and Technology Dr Harsh Vardhan, inaugurating the convocation urged the global scientific community to suggest robust strategy for ensuring sustainability in these vital sectors. The Minister also formally launched the electronic version of the CAETS report on “Transitioning to Lower Carbon Economy: Technological and Engineering Considerations for Building and Transportation Sectors”.
The eminent nuclear scientist Dr.Baldev Raj is the first Indian to head the premier global Body CAETS, and the CONVOCATION-2015 is credited with the unique distinction of convergence of such reputed international domain specialists for the first time in India.
Energy resources’ sustainability and their cost efficiencies will dictate shift to lower carbon non-fossil energy systems.
Global energy consumption will grow from 524 to 820 quadrillion BTU between 2010 and 2040 leading to GHG emission increase by more than 40% from the present level under business as usual scenario. Since the dynamics of energy growth is driven by the population and wealth enhancements, it is important to keep track of these growth dynamics in different countries.
The transition to lower carbon regime require a careful assessment of current energy and emission loads at national level for setting energy/emission reduction targets and timelines.
Developing application-based energy scenarios is essential for devising future energy efficient systems. A typical example is the highly interconnected electricity, transport and heating sectors. The coal based energy continues to attract engineers to develop cleaner process options and minimize GHG emissions keeping in mind the transitional priorities.
The actions include up gradation of beneficiation, ultra supercritical combustion and integrated gas combined cycle concept for gasification, co-firing of coal and biomass etc,. For next generation solar cell energy materials beyond silicon, conjugate organics, inorganic quantum dots and mixed semiconductor oxides/peroxides need to be adapted.
Similar challenges are foreseen in high energy density battery and membrane materials for fuel cells. Light based technologies can play a major part in developing future energy efficient systems. There is a need to integrate photonic and bio photonic technologies.
The expert panel, which deliberated on these issues, stressed the need to develop high strength light-weight materials including nano composites and nano structured steels, electrochemical and catalytic options for hydrogen generation, which are adaptable for building and transportation sectors.
