Correlation Between Central Receiver Size and Solar Field Using Flat Heliostats

In Central Receiver Systems (CRSs), thousands of heliostats track the sunrays and reflect beam radiation on to a receiver surface. The size of the reflected image and the extent of reflection from the heliostats are one of the important criteria that need to be taken into account while designing a receiver, since spillage losses may vary from 2 to 16% of the total losses. The present study aims to determine the size of an external cylindrical receiver, such that the rays reflected from all the heliostats in the field are intercepted. 

24 x 7 Power for all : Strategies for Karnataka

This study was commissioned by Karnataka Electricity Regulatory Commission (KERC) to identify key implementable strategies for the state of Karnataka for achieving the objectives of 24x7 Power for All The study describes the power supply scenario in the State including estimates for future energy demand The status of 24x7 power supply is analysed along the dimensions of access (electrification), adequacy (per capita consumption), affordability (cost of supply), availability (duration of supply), and reliability Future plans for generation capacity are analysed to determine the range of fore

Transition Metal Oxides as Cathodes for Li-ion battery: Structure, stability and substitution effects

First–principles DFT simulations are computationally demanding but are reasonably accurate in predicting properties of battery cathode materials. Properties relevant to selection of cathode
material include electrochemical potential, structural stability, energy/power density and cycle life etc. Computational screening of materials speeds up the process of material discovery by
saving on costs of experiments and time. In addition, it helps in developing correlation between properties and structural and chemical aspects. Here we analyze some of these aspects for the

A Sustainable Development Framework for India's Climate Policy: An Interim Report

As a large developing country, India’s challenge is to meet its development aspirations in a carbon-constrained world This study, undertaken by the Centre for Study of Science Technology and Policy (CSTEP) uses Sustainable Development (SD) as the overarching framework and aims at equitable access to energy, clean air and water, food, health and livelihoods and economic growth The study connects elements of SD in an integrated bottom-up approach to understand the implications for economy, energy trajectories, emissions and costs

Rare Earths Recovery from Secondary Resources: Opportunities, Challenges and Environmental impacts

Rare earths are not as rare as the name suggests, they are relatively abundant in the earth`s crust,
but their concentration is less in ore deposits, in particular heavy rare earths. Commercially,
REEs are extracted from the bastnasite, monazite and xenotime ores. The extraction of REEs
from mineral ore (primary source) is a complicated multi step process with a huge amount of
toxic wa ste released during the processes. The recovery of REEs from secondary sources such
