World’s First Thermal Battery Plant Unveiled In Andhra Pradesh.

The world's first-ever thermal battery plant will be unveiled in Andhra Pradesh by the state’s Chief Minister N Chandrababu Naidu on August 6, 2018.

Manufactured by the Bharat Energy Storage Technology Private Limited (BEST), the first-of-its-kind batteries will aim to boost renewable sources of energy production and reduce the dependence on non-renewable fossil fuel-based energy generation.
 
BACKGROUND

Though, Solar power is considered the most reliable source of energy, yet it has its drawbacks.

Energy Generation is not possible after sunset and in high rainfall areas.

This brings in the need for a robust energy of a storage infrastructure i.e. we can store energy.

Hence, the unveiling of the  'THERMAL BATTERY PLANT' is a landmark development in the field of technology and environment protection.

WE ALREADY HAVE LITHIUM ION BATTERIES - THEN WHY NEED OF THIS THERMAL BATTERY PLANT 

  • Lithium based batteries are limited by the life-cycle , making it a very expensive proposition with replacement needed every 6-7 years.
  • Lithium based batteries leave high carbon footprint.
  • Lithium's  sensitivity to extreme temperature  requires the energy storage system to be placed in conditioned temperatures , requiring about 8-10 percent energy storage for the cause.

ADVANTAGES OF THERMAL BATTERY
  • The technology help in mitigating 'Carbon Emission'.
  • It can also be used in remote locations, such as hilly terrains and islands.
  • It will also be used to store energy for telecommunication, commercial establishment, electric vehicles and highway charging stations.
KEY HIGHLIGHTS

• In the first phase, batteries suited for telecommunications, mini or microgrids and electric buses would be manufactured.

• The batteries are expected to run for up to 800kms on a single charge.

• Under the project, electric buses, produced in collaboration with Bilva Motors, a global consortium, could deliver an 800-kilometre range with a single charge, with the help of BEST's thermal cells.

• The cell can be customised to be charged in four or eight hours, depending on the source.

• It can also provide output ranging between 5Kwh and 1 Mwh.

• The thermal plant is expected to start commercial operations by May 2019.

NOTES 

This technology (Thermal Battery), patented in India by Dr Patrick Glynn in 2016, scores over Li-ion batteries due to lesser heat sensitivity, as well as a smaller carbon footprint.

The BEST also aims to set up a Greenfield Project in India, at an estimated cost of Rs. 660 crores, through which nearly 3000 jobs are expected to be created within three years time.

While conforming to the Indian government’s 2030 e-vehicles goal, BEST also plans to make batteries that are completely free of hard metal or inflammable substances, so that re-usable materials could make up 95 per cent of all thermal batteries.

Apart from these urban businesses, the plant is set to provide electricity to rural and remote areas of Andhra Pradesh

DIFFERENCE BETWEEN LITHIUM BASED AND THERMAL BATTERY PROCESS

Li-ion batteries work on the basis of electrical energy.
Energy is derived from this battery, when lithium atoms turn into lithium ions (Li+), and get stored when this reaction reverses.

Thermal batteries, on the other hand, use thermal energy to operate, i.e., the energy created by temperature differences.

Therefore, the energy transfer in thermal batteries helps store heat when heat travels from one part of the battery setup to the other.

For that to happen, a thermal battery consists of two parts: a cool zone known as sink, and a hot source called source. Both these sides consist of compounds known as phase-changing materials (PCMs), which can change their state of matter on the basis of a physical/chemical reaction.


South Korean carmaker Kia Motors Corp has signed a deal to invest about $1.1 billion to build its first factory in India’s Andhra Pradesh.

INDIA WILL BUY OIL FROM IRAN, DESPITE US SANCTION - IS THIS BRAVE STEP ?

Image
BACKGROUND - HOW ALL THIS ORIGINATED ? Like, In India - we have Lok Sabha & Rajya Sabha pass the bill and make that a law. Likewise, in USA - There is Congress. They pass the bill and make that a law. USA Government did the voting and passed the CAATSA Bill. CAATSA is an American law. The bill was passed during the 115th congress , in the Senate. On August 2, 2017, President Donald Trump signed it into law while issuing two statements simultaneously that he believed the legislation was "seriously flawed". CAATSA - Countering America's Adversaries Through Sanctions Act. US Government passed this CAATSA against three countries - Iran, North Korea and Russia. And also warned that if any other country deal with these three countries, then Sanctions will be imposed on that country too under CAATSA WHY CAN THE US IMPOSE ECONOMIC SANCTIONS ON OTHER COUNTRIES? There are many reasons - US is the part of NATO. US as a militarily is a very very p...

NEPAL- CHINA TRANSIT AGREEMENT - WILL THIS END INDIAN MONOPOLY ON TRANSIT ?

Image
WHAT JUST HAPPENED? In 2016 , Nepal and China signed the ' Transit Transport Agreement ' with this - China will give access to all it's roads, rail links and Ports to Nepal to do the Trade. Now In September 2018 - This agreement came into force (There was some timeline which not completed and agreement now in force) Thus, Now Nepal can now do the trade with other countries via China's Port, Rail Link and Roads. Nepal is a land-locked country. So, If Nepal wants to do Trade with other countries - Nepal can do only with Flights. [ There is no other option ] From last so many years, India is providing the facility to Nepal to use It's roads, ports to do the Trade with other countries. In 2015 - There came a ' Madhesis Issue ' which has severely affected Nepal and its economy.  Nepal has accused India of imposing an undeclared blockade. India has denied the allegations, stating the supply shortages have been imposed by Madheshi pro...

RBI ANNUAL REPORT - DEMONETISED CASH IS BACK - FAILURE OR SUCCESS - ?

Image
BACKGROUND Hope, everyone remember the Date 8-Nov-2016 - when Prime Minister Narendra Modi  announced high-value currency notes of Rs 500 and Rs 1,000 would cease to be public tender.  In the biggest-ever demonetization exercise India had seen. WHY THIS MOVE ? To stem (remove) the circulation of black money and fake currency. To choke terror funding and corruption.   WHAT HAPPENED NOW ? Finally, three months short of the second anniversary of demonetization , the Reserve Bank of India (RBI) has completed the counting of banned Rs 500 and Rs 1,000 notes that returned to the banking system post the note-ban.  And the results are not too good considering the pain the economy went through post demonetization. RBI released its Annual Report (of 268 Pages) for 2017-18 year. https://rbidocs.rbi.org.in/rdocs/AnnualReport/PDFs/0ANREPORT201718077745EC9A874DB38C991F580ED14242.PDF There are many things in this report related to Cryptocurrency...
