Hydrogen CNG

Current Affairs: Hydrogen CNG What is Blockchain? Vodafone Idea Merger 2018

Hydrogen-CNG (H-cng)

 

Pollution is a mega problem around the world. Air pollution is one of them.

The major contributors in Air pollution is transport system of a country which is adding Carbon dioxide (CO2), Carbon Monoxide (CO), nitrogen oxides etc.

Cities like Delhi is already using Compressed natural gas (CNG) based transportation system in a big way.

And Compressed natural gas (CNG) is already a hit in Public transport as well as among the private vehicle owners as an alternate fuel to run the vehicles.

CNG is much cleaner than Diesel & Petrol as it emits lesser carbon dioxide, carbon monoxide or other particulate matters which causes air pollution.

But now Scientists has found even better fuel or cleaner alternative which will be cleaner than even CNG & that is hydrogen based CNG or Hydrogen-CNG (HCNG or H2CNG).

 

Why hydrogen-cng in News

Hydrogen CNG

Hydrogen-CNG (H-CNG or H2CNG) as a fuel for transport systems in Delhi in the next three years is recommended to Supreme Court by the Environment Pollution Prevention & Control Authority (EPCA).

EPCA recommended Supreme Court that State run buses should switch to this Cleaner fuel (Hydrogen CNG or H-CNG) in two-three years so that we can move a step closer in controlling the ever rising air pollution problem in Delhi.

EPCA said to Supreme Court that we can introduce color coded sticker on vehicles running on Hydrogen CNG (H-CNG) which will further help identifying old vehicles which causes way more pollution & it’s better than odd even scheme for vehicle rotation scheme in Delhi.

CNG is available but Hydrogen has to be produced for making Hydrogen CNG  (H-CNG) be available as a fuel.

Production cost of hydrogen is high and it requires blending with natural gas to take the form of Hydrogen CNG (H-CNG) and be usable as fuel.

By using H-CNG as fuel we can further reduce the Carbon Monoxide emission by 70%. Also, engine must be calibrated to achieve emissions reductions when running on Hydrogen CNG (H-CNG).

Trials are going in Countries like South Korea, USA, Brazil.

About CNG

An alternative fuel for petrol, diesel to run vehicles. In Compressed natural gas (CNG), Methane gas(CH4) is stored at a high pressure so that its being used as a fuel.

CNG disperses quickly in air when released because natural gas is lighter than air so its safe even in the case of a spill.

Natural gas mainly found above oil deposits. It emits lesser carbon monoxide gas than petrol & diesel.


What is blockchain

current affairs blockchain

Blockchain is a digital ledger distributed equally to all. It verifies data transactions over time thus acting as official record keeper.

It’s a technology invented for cryptocurrencies like Bitcoin.

As defined in Forbes website, Blockchain is a protocol for a digital ledger that enables proof of ownership and the transfer of ownership from one entity to another without using a trusted third party intermediary (like a bank).

How it is safe and hackerproof

Blockchain keeps a record of every transactions(blocks) done on many specialized servers around the world. This creates a record of transactions i.e., chain which is distributed equally to all like a distributed database.

So these records can be verified with each other to check the authenticity
if both has the same record or not.

And due to this it is almost hacker proof because to manipulate it, a hacker has to enter into every record and do the manipulation because here no single centralized copy exists where one can go and do the manipulation that is why virtually impossible to break in.

Blockchain is a peer-to-peer network that is owned by no one but all can access it. It’s users can manage their own digital records.

Blockchain  which was introduced for financial transactions, as its famous with  Bitcoin (cryptocurrency) also called as digital gold. But its uses are far more.
Uses are like legal documentation, digital assets, various government sponsored subsidy management,  inventory management, medical records,  or anything which requires a safe and trusted version to transact.

Current Affairs BlockchainIt can revolutionize the way we transact and can increase much more transparency than any previous technology has.
