Yes

A few months back, Dr Harish Hiraniji ( Director, CMERI / director@cmeri.res.in ), handed over the CSIR-CMERI developed Solar DC Cooking System to the Asansol Braille Academy, West Bengal today

The CSIR-CMERI developed Solar DC Cooking System is a Solar Energy based Cooking System which consists of solar PV panel / charge controller / battery bank and / cooking oven.

When developed and sold commercially, this system is expected to sell for Rs 70,000

I figure the following are the main cost elements :

# 1.3 KW Solar PV panel ………………………….. Rs 40,000

# (48 V,100 Ah ) Battery Bank ( 4x12V )…. Rs 27,000

# DC operated Cooking Oven………………………. Rs 3,000

My Suggestion :

Let the Govt tells those 250 million families which are currently using a Gas Stove + LPG Cylinder :

“ Even now, you don’t own the LPG cylinder ( which STORES the energy ). You

only pay for the amount of LPG gas . Unfortunately, country spends Rs 70,000

Crores EVERY YEAR to import LPG and give you at a subsidized rate ( at Rs 450

for Rs 950 market price - almost 50 % of the free market price )

We are about to announce a BATTERY SWAPPING POLICY for electric vehicles ( mostly 2W / 3W ).

We propose that this policy ALSO covers batteries needed for CMERI developed SOLAR DC Cooking System

So you need to buy only the “ DC operated Cooking Oven “ ( costing approx. Rs 3,000 )

No need to buy / own that 48V – 100 Ah, battery bank . Nor do you need to buy / install rooftop Solar Panels

You just go to your nearest Energy Operator ( EO ) and “ lease “ that battery

When it is about to get discharged, take it back to that EO and swap it for a fully charged battery !

Convert from “ Ownership “ to “ Service “

Of course, we will continue to subsidize your “ Battery Swaps “ ( max 12 / year )

at Rs 400 per swap ( which amount will be linked to the ex-factory battery price

and will go up or down in some proportional linkage )

We are also thinking to subsidize your purchase of “ DC operated Cooking Oven “

Battery Swapping Policy in the Works

Extract :

Boost for ‘ battery- or energy-as-a-service ’ business models (BaaS )

In a major boost for electric vehicle adoption, the government will bring out a battery swapping policy as well as interoperability standards for promotion of zero-fossil fuel mobility.

Battery Swaps Put on Fast Charge to Attract EV Buyers / ET / 19 March 2022

Extract :

Ø Bengaluru-based startup Bounce this week announced a partnership with Greaves Retail, making the latter the first to join the Bounce Infinity battery-swap network.

Ø Bounce says it has completed more than 1 million swaps, having launched its electric scooter, the Infinity E1, in December 2021, offered with the BaaS feature.

Ø For those opting for the latter, without the battery, the scooter is priced at Rs 37,000. It costs Rs 60,000 with the battery. ( This means that the Battery / 48 V – 39AH / costs Rs 23,000 )

Battery Swapping – the nitty-gritty you need to know / ET Auto / 18 Aug 2021

Extract :

Ø Now with the recent regulations, customers in India can buy a vehicle without a battery and take it on lease from an Energy Operator ( EO )

Ø Charged batteries are leased from the outlets of Energy Operator ( EO ) – when the battery drains , the user can visit any EO outlet , swap the discharged battery with a charged battery and pay for the electricity consumed

Ø The entire process of battery swapping for E2W takes three to five minutes, imitating the fuel pump experience

Ø Battery swapping technically converts the capital cost of the most expensive component of an EV , ie. the battery, to an operational cost

Ø Battery swapping customers can subscribe to monthly or annual battery swapping plan or adopt a pay-per-use model per their needs

Ø Batteries for vehicle categories such as 2W's and 3W's are best suited for swapping. These are light in weight ( < 10 Kg ) and can be easily swapped by the vehicle users

Ø THIS IS SOMEWHAT SIMILAR TO HOW WE USE LPG CYLINDERS IN INDIA. HOUSEHOLD OWNERS NEVER OWN THE CYLINDERS

My Suggestion to be evaluated with following figures :

Ø At present, Govt subsidizes the use of LPG cylinders for families earning less than Rs 10 Lakh / year

Ø Govt directly transfers this subsidy amount into the bank account of the eligible users, once a month ( for 1 cylinder / month = 12 cylinders / year )

Ø Free market price of an LPG cylinder = Approx. Rs 950

Ø Subsidy Amount per cylinder = Approx. Rs 450

Ø Hence, total Annual Subsidy = Rs 5400 ( 12 x 450 )

Ø Price of an ave. 2 burner gas stove = Rs 1500 ( Range of Rs 1000 – Rs 2000 )

Ø Weight of a LPG cylinder = 14.2 Kg

Why India, the poorest of super-emitters, will need a different path to net-zero / ET / 19 March 2022

Extract :

> Air pollution generated indoors kills 1.7 million Indians each year and

causes $ 37 billion of economic losses, according to a Global Burden of

Disease study. A major contributor to noxious air in the home is the

burning of firewood for heat and cooking.

Switching more than 88 million poor households to liquefied petroleum

gas since 2016 has significantly reduced the health risks associated with

pollution. It’s also saved women from hours of collecting wood.

Ø Although the change slightly increased India’s emissions, “the development

gains are so big that it’s just a no-brainer,” says the Centre for Policy Research’s

Dubash.

Eventually, similar programs could be used to shift to electricity or a carbon-free

gas for cooking.

Cost to install a 1 KW Solar System on a residential rooftop can range from Rs 45,000 – Rs 85,000

( Mercom India / 03 Nov 2020 )

Extract :

Ø The cost of a 1 KW rooftop solar panel ranges from Rs 45,000 ( $ 612 ) to Rs 85,000 ( $ 1156 ) excluding the cost of batteries. We are assuming the rooftop solar systems are connected to the grid and the power is not stored in batteries

Bounce Infinity partners with BattRE to provide battery swapping network / BL / 26 Mar 2022

Extract :

Ø Consumers looking for swapping batteries for their scooters can search for the nearest swapping location on the designated app and every swap takes no longer than 1 – 2 minutes, addressing the range anxiety

Ø “ I believe, battery swapping infrastructure and BaaS ( Battery-as-a-Service ) will be useful not just for personal use but also act as an important support system for COMMERCIAL USE cases “ , said Nischal Chaudhary, Founder , BattRE

Inside China's electric drive for swappable car batteries / EuroNews / 25 Mar 2022

Extract :

Ø Four companies – automakers Nio and Geely, battery swap developer Aulton and state-owned oil producer Sinopec – say they plan to establish a total of 24,000 swap stations across the country by 2025, up from about 1,400 today.

Ø In fact, China is pushing hard for swappable batteries for electric vehicles (EVs) as a supplement to regular vehicle charging, with the government throwing its weight behind several companies advancing the technology.

India to study global models for solar roofs with storage / 23 March 2022

Extract :

Ø India plans to study models deployed by global firms akin to Tesla Inc. for establishing built-in solar roof and battery storage programs

Ø This comes towards the backdrop of the nation’s unfolding power transition whereby the Clean Cooking Mission is wanting to leverage rooftop solar and in-house battery infrastructure to present uninterrupted electrical energy to about 250 million households

Ø Any shift in the direction of solar power as home cooking gasoline will assist in power import substitution and trim India’s hefty power import invoice whereas selling the home solar business

Mumbai becomes first South Asian city to detail net-zero roadmap / 15 March 2022

Extract :

Ø Drawing on inputs from officials, citizens, researchers and companies, Mumbai’s plan lists changes across six domains. This includes investments in housing, electrifying public transport and more walkable roads; flood-resistant drainage and water conservation apart from adding open spaces, investing in clean water and sanitation, and rooftop solar capacities.

Ø The city will also spend on projects like retrofitting low-income homes with electricity-efficient equipment.
