How to reduce Carbon Emission to Net Zero ?

 


 

Not by 2050 but by 2025 ?


Context :

India urges G20 nations to bring down per capita emissions by ’30 /  HT / 25 July 2021

 

Extract :

Ø  The target of reducing emissions to net zero by mid-century, proposed by some countries, will not be adequate in view of the fast-depleting global carbon space, India said in its official statement at the G20 energy and climate joint ministerial meeting

 

Ø  “We have noted the pledges made by some countries to achieve Net Zero GHG emissions or carbon neutrality by or around mid-century. However, this may not be adequate in view of fast depleting available carbon space. Therefore, and keeping in view the legitimate need of developing countries to grow, we urge G20 countries to commit to bringing down per capita emissions to the global average by 2030,” said the statement shared by the Union Environment ministry on Saturday.

 

Ø  According to data provided by the Climate Watch by World Resources Institute, India emits,

         #   7.1% of global emissions and

         #   Has per capita emissions of about 2.47 Tco2e ( tonnes of carbon

              dioxide equivalent ),          

         #   As compared to the global average of 6.45 tco2 / per capita

 

Ø  In comparison to top emitters, India’s per capita emissions are

        #   7.0  times lower than that of the United States,

       #    3.4  times lower compared to China’s and

       #    3.0  times lower compared to the EU.

 

Ø  Union environment minister, Bhupender Yadav, ( bhupender.yadav@sansad.nic.in ) said the world should not be shifting goalposts and setting new benchmarks for global climate ambition during the G20 ministerial meeting on Friday.

 

Ø  He also made it clear that India will accelerate action on climate change only when there is enough support from developed countries. “...The momentum of climate action can only be accelerated when there is enough support through means of implementation including finance and technology,” he said.

 

 

Ø  “ For India, scaling up renewable energy and nature-based solutions can bring new jobs and better health, but much depends on clean technology partnerships for industrial production,” said Ulka Kelkar, ( ulka.kelkar@wri.org  ), director of the climate programme at the World Resources Institute, India.

New Solar Cell Innovation Provides 1,000 Times More Power   /   Interesting Engineering     /  22 July 2021


Extract :

Ø  The energy generation of ferroelectric crystals in solar cells can be increased by a factor of a thousand, according to a statement from  Martin Luther University Halle-Wittenberg (MLU).


Ø  Researchers from MLU found that with alternately placed crystalline layers of barium titanate, strontium titanate, and calcium titanate, they could greatly increase the efficiency of solar panels. Their findings are published in the journal Science Advances.


Ø  "The important thing here is that a ferroelectric material is alternated with a paraelectric material. Although the latter does not have separated charges, it can become ferroelectric under certain conditions, for example at low temperatures or when its chemical structure is slightly modified," Dr Akash Bhatnagar, from MLU’s Centre for Innovation Competence SiLi-nano, explained in the MLU press release.


Ø  The researchers found that their layered material enabled a current flow 1,000 times stronger than measured in pure barium titanate of the equivalent thickness.


Ø  The team also showed that the measurements remained almost constant over a six-month period, meaning the material may be robust enough for commercial application. Next, they will continue to research the exact cause of the photoelectric effect in their layered material, with a view to eventual deployment at a mass scale

World's cheapest energy storage will be an  iron-air battery  /  RechargeNews  /  23 July 2021


Extract :

Ø  Form Energy, the billionaire-backed start-up that claimed to have developed an innovative low-cost 150-hour battery, has finally revealed its battery chemistry after more than a year of high-profile secrecy.


Ø  The Boston-based company says its first commercial product is a “rechargeable iron-air battery capable of delivering electricity for 100 hours at system costs competitive with conventional power plants and at less than 1/10th the cost of lithium-ion”.


Ø  A cheap, safe battery able to store energy for long periods of time is the holy grail of the renewable energy sector, as it would be capable of removing the issue of wind and solar’s variability at a low cost.


Ø  With French financial advisers Lazard putting the levelised cost of storage (LCOS) of large-scale lithium-ion batteries at $132-245/MWh in its industry-standard annual report, Form’s battery—at a tenth of that cost — would be the cheapest type of energy storage available by some distance.


Ø  This battery can be used continuously over a multi-day period and will enable a reliable, secure, and fully renewable electric grid year-round,” said Form Energy.


Ø  Or as Greg Lydkovsky, global head of R&D at steel giant ArcelorMittal — Form Energy’s latest investor — put it, the technology “ holds exciting potential to overcome the intermittent supply of renewable energy”.


Ø  Form Energy president and chief operating officer Ted Wiley said:


     “ We’ve completed the science, what’s left to do is scale up from lab-scale

        prototypes to grid-scale  power plants.”

      

Ø  “[At full production], the modules will produce electricity for one-tenth the cost of any technology available today for grid storage.”


Ø  The battery is said to work through “reversible oxidation of iron”. In discharge mode, thousands of tiny iron pellets are exposed to the air, which makes them rust (ie, the iron turning to iron oxide). When the system is charged with an electric current, the oxygen in the rust is removed, and it reverts back to iron.


Ø  Wiley said that a 300 MW “pilot” project for Minnesota-based Great River Energy will be commissioned in 2023.


Ø  Canadian start-up Zinc8, was the first to break cover with a commercial product in 2019, announcing that it would be deploying a zinc-air battery system with the technological capability of providing 100-plus hours of storage.


Ø  And Oregon-based ESS, which claims to have a market value of $1.1bn, already sells a flow battery that uses iron as its primary ingredient.


Ø  Current Form Energy investors also include Italian oil giant Eni and Macquarie Capital, while ArcelorMittal revealed a $25m investment in the company on Thursday.


Ø  Form has also announced a Series D financing round that aims to raise $200m

==================================================

Dear Shri Bhupeder Yadavji ,


Thank you for ,

#   Doing some plain-speaking to G 20

#   Asking their help for FUNDS – and equally importantly – for TECHNOLOGY

     TRANSFER

 

I urge you to request ,

Ø  Chancellor Angela Merkel ( Germany ) to persuade Dr Akash Bhatnagar ( MUL ) for transferring “ Layered Material “ technology which produces 1000 times more power than current Solar Panels

 

Ø  President Joe Biden ( USA ), to persuade Ted Wiley ( COO – Form Energy / Boston ) for transferring technology for “ Rechargeable IRON-AIR battery “, which can store grid-level power for days together and cost only 10 % of currently popular Lithium-ion batteries

==================================================

 

HERE ARE SOME IMPLICATIONS OF QUICK COMMERCIALIZATION OF THESE TECHNOLOGIES :

 

 [ A ]     Power For Homes / Offices / Shops / Factories :

Ø  With current Silicon PV  Solar panels, we need 10 sq meter of panels to generate 1 KW of electricity

Ø  Premises with high level of electric consumption, need 10 KW ( requiring 100 Sq Meter = 1076 Sq Ft )

Ø  But, if we were to use MUL ( layered material solar panels ), we would need only 1 . 076 SQ FEET of solar panel to generate 10 KW ( approx. 5 sq feet to generate 50 KW )

 

Ø  This means :


#   Smallest thatched hut can have, practically UNLIMITED electricity

#   Each and every building can generate more power than it needs and be

     able to SELL its excess power to nearby buildings ( which may not have

     required funds for their own Solar Installations )

     

           Soon to be introduced Electricity Amendment Bill seeks to enable

           power consumers to choose from  multiple service providers as in case

           of telecom services

           

 

#   All buildings can STORE their ( generated ) power in “ Re-chargeable

      Iron Battery Storage System  “ ( also installed in the building terrace )

      and use Solar Power for “ Battery Charging Outlets “ on the ground floor

      for charging Lithium-ion batteries of their Electric Vehicles


#    Cheap / Abundant solar power, stored in terrace-based Iron-Air battery

      ( for months ), can turn every home into a " Cottage Industry " and

       convert jobless youth into  millions of Self-Employed  

    

   (  ReadA Tale of Two States  / Congratulations, Shri Vijaybhai Rupaniji, )

 

 

 [ B ]    Solar Cookers

   Having Roof-based “ Re-chargeable Iron Battery Storage System “, (

   which can store 50 KW power for days together ), kitchens in each and

   every flat ( apartment ), can use SOLAR CHULHAS ( Solar Cookers ) for

   cooking their food ( even on cloudy days ). Not only will this save import

    of LPG - CNG (worth Rs 40,000 crore / year ), but save women from

    respiratory diseases

         

             ( Read :  Air Pollution Sources : And “ How to save 2.5 Lakh lives )


             Availability of domestically-produced , cheap / abundant solar electric

             power would lead to an exploding use of Domestic Appliances ( fridges -

             air conditioners - microwave ovens - TVs - Desktop Computers etc ) .


             In turn, this booming industry would generate millions of new jobs (

             Remember ECONOMICS 101 -  " Human Wants are Insatiable " )
             

 

 

  [ C ]     Solar Roof-top Cars

 Going one step further, imagine not needing road-side battery charging

 stations for charging Lithium-ion batteries !


 Here is a possible scenario :

     Currently ( to my limited knowledge ) , following 3 companies are working

     on Electric Cars whose Li-Ion batteries get ( some ) charge from Solar

      Panels mounted on their roof-tops 

      SONO Motors 

      LightYear

          Aptera  ( Read :  Solar Powered EV : 1,000 Miles with Single Charging ?  )

 

      Some other EV manufacturers ( including Tesla ) are also experimenting

      with roof-top solar panels

      Even our own ISRO gave a working demo of such vehicle, a few years

        ago

       None have ( so far ) succeeded in a commercial launch

        Main problem is that, to generate 1 Kwh, the solar panel would need to

        be ( approx. ) 5 feet x 3 feet ( 15 sq ft ) in size and weigh 40 lbs  . A

        Electric car may need between 50 Kw – 150 Kw to keep its Li- ion

        batteries fully charged . This means, a 5 feet x 3 feet car rooftop can

        give only 1 Kw


        

        But a 15 sq ftMulti Layered panel ( from MUL ) can generate 150 Kw

        of power ! Car would never need a road-side battery charging station !

       

       Now if all EV can sport such solar panels on their rooftops, there will be no

      “ Range Anxiety “ and a  total change-over to EVs , all over the world,

       would happen by 2030, resulting in great reduction in Carbon Emission !


        With EVs not needing petrol or diesel as fuel, this would mean gradual

        dismantling of  OIL EXPLORATION -EXPLOITATION - REFINING industry.

        As far as lakhs of existing Gas Stations are concerned, only a few ( 10 %

       ), may survive by switching over to Li-ion battery charging stations . Rest

        will need to close down 

      

       

 [ D ]    Power Transmission Lines

      Now, if each and every building ( including in rural areas ) was to generate

      – and STORE – its own Solar Power, there would be no need for any

       TRANSMISSION LINES ! 

      

     This may disrupt the business of DISCOMs

          ( Read :  Wireless Power Transmission ? / 27 Aug 2020 )

 

 

[ E ]    Phasing Out of Fossil Fuel Power Plants

    If UNLIMITED / ABUNDANT solar power was to become available ( 24x365 ,

    because of storage in Iron-Air GRID-SIZE batteries ), then by 2025, then

    there would be no need for any power plants based on COAL –GAS – FUEL

    etc. World would be able to gradually shut these down so that, by 2030, no

    such Carbon Emitting / polluting plants are working . 

    That would dramatically reduce global warming

           

          ( Read :  

          A Long Term Solution for Low PLF ?  /   The Surge of Solar  ) 

 

     Decommissioning coal power plants older than 25 years could save Rs

       37,000 cr, reveals study 


      



[ F ]    Eliminating Water Shortage

    Again, year-round availability of CHEAP / UNLIMITED solar power would

    enable, coastal countries  around the world to set up thousands of Solar-

    powered DESALINATION PLANTS and overcome WATER SHORTAGE. Such

    water can even be pumped to arid / desert INLAND areas, hundreds of Km

    away  coast ( using cheap electricity for pumping ). “ Interlinking of Rivers 

    project needs lots of power 

     

         ( Read :  Solar-Powered Desalination Device Aims to Deliver Water to

                       400,000 Kenyans )

 

 

[ G ]    Stopping Desertification / Starting Afforestation / Agriculture

           By being able to use cheap solar power to pump water over hundreds of

           kilometers, we would be able  to plant trees in desert areas. In turn, these

           “ desert-turned-forests “ would absorb carbon from the air.

            Deserts / arid zones can be used for agriculture

           

 

[ H ]    Low Cost Economy competing in Export Market

           Electric power constitutes between 10 % to 20 % of the total

           manufacturing cost of most engineering and consumer products . With

           availability of ABUNDANT and almost FREE  power , manufacturing costs

           will drop drastically, making India a truly LOW COST ECONOMY

          

[ I ]    Other Renewable Power Projects

           Abundant / cheap solar power may slow down other renewable power

           projects, such as :

                #    Nuclear

                #    Wind

                #    Hydro

-       And slow down research on TIDAL – FUSION – GREEN HYDROGEN

        technologies


Any Down-side of abundant / cheap solar power ?

Ø         This may lead to a “ Waste everything by a Throw-Away “  economy (

           everything is so cheap )

Ø         It may lead to over-exploitation of Natural Resources
