Hydrogen Fuel

Ministry of Road Transport and Highways has notified in 2016 for use of Hydrogen as an automotive fuel in the country.

The Hydrogen fuel for Internal Combustion Engine can be formed by blending 18% of Hydrogen with CNG (HCNG).

  • Hydrogen is a clean zero-carbon fuel burned with oxygen that produces only water.
  • Hydrogen is an energy carrier that can be used to store, move, and deliver energy produced from other sources.
  • These qualities make it an attractive fuel option for transportation and electricity generation applications.
  • Sources - Hydrogen can be produced from many domestic resources, such as natural gas, nuclear power, biomass, and renewable power like solar and wind.
  • Methods - Hydrogen fuel can be produced through several methods.
    1. Thermal processes (Natural gas reforming, Coal gasification, Biomass gasification, and Reforming of renewable liquid fuels),
    2. Electrolytic processes (Electrolytic hydrogen production),
    3. Solar-driven processes (Photo-biological processes, solar thermo-chemical processes, and photo-electrochemical processes) and
    4. Biological processes (Microbial biomass conversion and photo-biological processes).
  • The most common methods today are natural gas reforming (a thermal process), and electrolysis.
  • Uses - Hydrogen fuel cells produce electricity by combining hydrogen and oxygen atoms.
  • So, hydrogen can be used in fuel cells or internal combustion engines.
  • It can be used in cars, in houses, for portable power, and in many more applications.

Radio Frequency Identification

Indian Army has commenced the implementation of Radio Frequency Identification (RFID) tagging of its ammunition inventory.

  • Radio Frequency Identification is a wireless communication technology.
  • It uses the electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to passively identify a tagged object.
  • RFID system comprised of two components: tags and readers.
  • RFID Tags use radio waves to communicate their identity and other information to nearby readers.
  • RFID tags can store a range of information from one serial number to several pages of data. They can be passive or active.
    1. Passive tags are powered by the reader and do not have a battery.
    2. Active tags are powered by batteries.
  • Reader is a network-connected device that has one or more antennas that emit radio waves and receive signals back from the RFID tag.
  • It uses radio waves to transmit signals that activate the tag. Once activated, the tag sends a wave back to the antenna, where it is translated into data.
  • Readers can be mobile so that they can be carried by hand, or they can be mounted on a post or overhead.

KIRAN Scheme

Around 110 women scientists in ‘Women Scientist Scheme’ received financial assistance under Knowledge Involvement in Research Advancement for Nurturing (KIRAN) Scheme during 2020-21.

  • In 2014, Department of Science and Technology has restructured all the women specific programmes under one umbrella scheme ‘KIRAN’.
  • KIRAN is addressing various issues related with women scientists (e.g. unemployment, relocation etc.) and aimed to provide opportunities in
    1. Research (WOS-A),
    2. Technology development/demonstration (WOS-B), and
    3. Self-employment (WOS-C) etc.
  • KIRAN is actively involved in taking proactive measures, under the name CURIE (Consolidation of University Research for Innovation and Excellence in Women Universities).
  • Under CURIE, the state-of-the-art infrastructure will be developed in women universities in order to attract, train and retain promising girls students in S&T domain.
