Concentrating solar power (CSP) technologies use different mirror configurations to concentrate the sun’s light energy onto a receiver and convert it into heat. The heat can then be used to create steam to drive a turbine to produce electrical power or used as industrial process heat. CSP, which is commonly termed as solar thermal electricity, has attained 110 MW global capacity addition in year 2016/17, bringing global capacity to more than 4.8 GW by year’s end (2017). Globally, the pace of CSP installations in 2016 was observed to be slow.
India has daily average 4–7 kWh/m2 solar insolation with daily average direct normal irradiance (DNI)1 of 4.3–4.54 kWh/m2 (Figure 1). With aggressive Government solar policies by the end of 2017, India is expected to achieve total installed capacity of 18 GW. It has been a great year so far, around 8.8 GW has been added in 2016/17. India is expected to become a major player in CSP by the year 2050 (Figure 2). The techno-commercial potential of CSP in India is believed to be more than 2,800 GW in India.
In the year 2010/11 capital cost for photovoltaic (PV) and CSP were 17 crore/MW and 13 crore/MW, respectively. Capital cost of PV for 2016/17 got reduced to 68% of its cost in 2010/11, but CSP capital cost reduced only 7% for the same period. High capital cost also increased the power generation cost leading to high CSP tariff in India (INR12/ kWh). Payback period for CSP projects is higher than the solar PV projects. There is need for competitive for smooth acceleration of CSP projects.

Molten Salt Tower echnology for India
Power generation is the backbone of India’s solar sector. Sheela K Ramasesha highlights the merits of considering the solar molten salt tower technology in the country’s power mix to achieve a quicker and more efficient way of power production.
LPG ADOPTION BY RURAL HOUSEHOLDS: Financial Instrument to Push Refills
One of the major health hazards in India stems from household air pollution. The use of the traditional cooking stove, called chulha, involves burning of biomass, thereby releasing smoke that is a leading cause of illness and death. In this article, Debajit Palit, Martand Shardul, and Deborshi Brahmachari discuss the advantages of replacing biomass stoves with LPG and recommend an innovative financial instrument for increasing the uptake of LPG refills by rural households
JAPAN ENERGY FIRM INPEX SETS 2050 NET-ZERO EMISSION GOAL
Inpex Corp, Japan’s biggest oil and gas producer, said it is targeting net-zero carbon emissions by 2050 through the expansion of renewable and hydrogen energy as well as the use of carbon capture technology.
INDIA TO WITNESS FASTEST RISE IN ENERGY DEMAND BY 2040: IEA
In a report titled, ‘The India Energy Outlook 2021’, the International Energy Agency (IEA) said, the rapid expansion of solar power combined with favourable policies is transforming India’s electricity sector, allowing the country to offer clean, affordable, and reliable power to a growing number of households and businesses.
EMISSIONS CONTROL IN THERMAL POWER STATIONS: A Long Road to Cross
In this article, Raghav Pachouri brings out the current situation and the challenges confronting us regarding emissions control in thermal power stations (TPSs) in India. While analysing the impact of the power sector on air pollution levels, he highlights the current status of compliance in India (especially Delhi-NCR and critically polluted areas) till June 2020 after revised emission norms for TPSs came into effect on December 7, 2015. He also dwells on the major roadblocks in the timely compliance of emission norms and also offers a few solutions.
Managing Air pollution From Crop Burning
The perils of crop-residue burning contribute to major environmental degradation. In this article, TCA Avni and Sunil Dhingra discuss how the practice of stubble burning is responsible for poor air quality and loss of agricultural biodiversity. They highlight the importance of managing paddy residue and offer sustainable solutions, incentives, and alternatives to crop burning.
GOVERNMENT EXTENDS TENURE OF CENTRAL ELECTRICITY REGULATORY COMMISSION CHIEF, MEMBERS TILL NEXT YEAR
The government has issued order for extension of the tenure of former Gujarat cadre bureaucrat Pradeep Kumar Pujari as chairperson of the Central Electricity Regulatory Commission (CERC) till mid-next year.
