What is the News?

The formal launch of the Indian Oil Corporation’s Surya Natan solar cook-stove at the India Energy Week 2023 must be looked at closely from the point of view of India’s national energy story.

What is Surya Natan?

Surya Nutan is a Stationary, rechargeable, and always kitchen-connected indoor solar cooking.

Developed by: Indian Oil Corporation(IOC)

Working: Surya Nutan works in a Hybrid Mode (i.e. can work on both solar & auxiliary energy sources simultaneously) which makes it a reliable cooking solution.

– In solar mode, the stove collects energy from the sun, converts it into heat through a specially designed heating element, stores thermal energy in a scientifically proven thermal battery and reconverts the energy for use in indoor cooking. The energy captured not just covers the daytime cooking needs of a family of four but also the night meal.

Significance: Surya Nutan can be used in all weather and seasons including when the Sun is not available for long durations or for continuous days, such as monsoons and extreme winters.

– Insulation design of Surya Nutan minimizes radiative and conductive heat losses.

– Surya Nutan is a low or no-maintenance system and the product has a long life.

– The stove which entails a one-time procurement cost and has zero maintenance, is being touted as a substitute for fossil fuels. It does not have a traditional battery that needs replacement. Also, the solar panel has a 25-year life.
