India ranks 78th on WEF Energy Transition Index

India was ranked at 78th among 114 countries on World Economic Forum’s (WEF) Energy Transition Index  (ETI) released as part of report titled Fostering Effective Energy Transition. The index ranks countries on how well they are able to balance energy security and access with environmental sustainability and affordability.

Key Facts

Top 10 countries in 2018 ETI: Sweden (1st), Norway (2nd), Switzerland (3rd), Finland (4th), Denmark (5th), Netherlands (6th), the UK (7th), Austria (8th), France (9th) and Iceland (10th).

BRICS Countries in ETI: Brazil (38th), Russia (70th) and China (76th).

India related facts

According to report, India has taken bold measures to improve energy access, energy efficiency and to improve deployment of renewable sources of energy. However, energy transition in India will require large investments and enabling environment along with robust regulatory frameworks to support transition.

India is at crossroads in its energy transition journey. Its energy needs are primarily met by fossil fuels with implications for environmental sustainability and increasing energy import costs. Furthermore, considerable share of India’s population still lacks access to electricity and clean cooking fuel.

In 2018 ETI, India ranks in third performance quartile and third readiness quartile, making it emerging country that is approaching the leapfrog category. Interestingly, India has improved its performance score by 5.6 percentage points between 2013 and 2018 period, mainly with improved energy access, reduced subsidies and reduced import costs. India has largest government-mandated renewable energy programme, with target of 175 GW renewable energy capacity by 2022, and it announced plans to shift completely to electric vehicles by 2030.


IISc scientists develop first super critical carbon dioxide (S-CO2) Brayton Test Loop facility

Scientists from Indian Institute of Science (IISc), Bengaluru have indigenously developed country’s first super critical carbon dioxide (S-CO2) Brayton Test Loop facility. The facility was inaugurated at the IISc campus. It is first test loop technology coupled with solar heat source in world that will generate clean energy from power plants, including solar thermal.

Key Facts

The facility is part of Indo-US consortium- Solar Energy Research Institute for India and United States (SERIIUS). It was developed by research group at inter-disciplinary centre for energy research of IISc as part of consortium. Funding was provided by Department of Science and Technology (DS&T) under Indo-US Joint Clean Energy Research and Development Centre programme.

This facility uses supercritical CO2 (SCO2) instead of steam to generate more power. Supercritical refers to state of CO2 above its critical temperature of 31 C and critical pressure of 73 atmospheres, which makes it twice as dense as steam. S-CO2 operated in closed loop Brayton cycle increases efficiency of energy conversion by as much as 50% or more.


This next generation, efficient, compact, waterless super critical CO2 Brayton cycle test loop for power generation will be useful for meeting energy needs of the country. It has potential to replace steam based nuclear and thermal power plants, thus reducing the carbon foot print significantly. Besides, increasing power generation and making process more efficient, the new technology will make power plants cheaper with lower operating costs.

It will be indigenous initiative for setting up next generation of solar thermal power plants. This gives India opportunity to become world leader in this technology, and fulfil major objective of National Solar Mission which emphasizes indigenous manufacturing.
