Hydrogen is right choice as fuel for automobiles: Scientist

Hyderabad, Oct 9: As India plans to give a robust push to promote use of electric vehicles, a top scientist says hydrogen-based system would be the right choice in the long run given its potential to become fuelof the next generation.

The Indian Space Research Organisation (ISRO) had come out with a demonstration vehicle using hydrogen itself as fuel, G Madhavan Nair, the former chairman of the space agency, said.

He was referring to a hydrogen-powered bus developed four years ago by Tata Motors and ISRO after several years of research.

"In the long run, I will say that hydrogen-based thing will be the right choice because hydrogen has to become the fuel of the next generation," Nair told PTI in an interview.

India is looking at having an all-electric car fleet by 2030 with an express objective of lowering the fuel import bill and the running cost of vehicles. The government is aggressively trying to push the sales and production of EVs in the country through schemes such as FAME India.

State-run Energy Efficiency Services Ltd (EESL) last month said it will procure 10,000 electric cars.

According to Piyush Goyal, who held power portfolio till recently, India aims to become 100 per cent e-vehicle nation by 2030.

Union transport minister Nitin Gadkari has earlier asked automobile manufacturers in the country to go for eco-friendly alternative fuels, else he would 'bulldoze' them.

"We should move towards alternative fuel... I am going to do this, whether you like it or not. And I am not going to ask you. I will bulldoze it. For pollution, for imports, my ideas are crystal clear. The government has a crystal-clear policy to reduce imports and curb pollution," Gadkari said. Nair said the hydrogen fuel cell that directly powers vehicles is "pretty expensive these days" and, so, one has to evolve a low-cost fuel cells technology, to make them viable.

"And how to generate hydrogen in an economical way and then how to make fuel cells...these are some of the technology challenges. We should mount a research and development programme in this regard," he said.

He is of the view that disposing of lithium-ion batteries (LiBs) after use in EVs is going to be "tough".

"Lithium, you cannot throw it around. That becomes the most polluting thing. There has to be an adequate mechanism for collection and reprocessing," Nair said.

LiB has a life of five to seven years, which can be stretched up to 10 years, according to him.

"Disposals (therafter)...when you have millions of (electric) cars like this (LiB-operated)...they should not get caught in the normal way and pollute the environment," Nair said.

The availability of lithium is scarce and that's why the cost of LiBs is high, he said.

"Secondly, handling (lithium) is difficult, you require moisture-free environment.

That's why I say for the long-run, one should look for (Hydrogen) fuel cell which is something like a battery-sized box but does this conversion of hydrogen into electricity. If you invest on that, I think we will have a much better opportunity," Nair said. According to industry officials, hydrogen fuel-cell powered vehicles are "non-polluting", and water vapour is the only emission.

In such vehicles, hydrogen is stored in compressed form, which combines with oxygen in the air to generate electricity, which is used to charge the fuel cells to power their motor, they noted.

New Delhi, Jul 13: The Telecom Regulatory Authority of India (TRAI) has blocked Bharti Airtel's Platinum and Vodafone Idea's RedX premium plans that offer faster data speeds and priority services to customers as both the plans were violating net neutrality norms.

The telecom watchdog has asked Bharti Airtel to explain within seven days how such a similar plan being launched does not violate the rules of net neutrality.

Vodafone Idea's RedX plan has been in the market since November 2019. They made some modifications in May 2020 and the Bharti Airtel was soon going to launch a similar plan.

According to TRAI, the higher speed for premium customers discriminate against others and violates net neutrality.

Responding to TRAI's move, Airtel spokesperson said: "We are passionate about delivering the best network and service experience to all our customers. This is why we have a relentless obsession to eliminate faults and have been consistently recognised by international agencies as the best network in terms of speed, latency and video experience."

"At the same time, we want to keep raising the bar for our post-paid customers in terms of service and responsiveness. This is an ongoing effort at our end," the spokesperson said.

Washington D.C: One of the greatest spectacles of modern art is still thriving in the Australian outback as confirmed by satellite imagery of NASA. The Marree Man is a massive geoglyph depicting an aboriginal hunter, that spans over 2.6 miles in the Southern Australian region.

Discovered by a pilot in 1998, its origin still remains a mystery even to this date.

The Marree Man was given a new lease of life in 2016 when a group of people from the neighboring town of Marree plowed its lines to avert its fading due to erosion.

After NASA shared the image of the art-work that was taken in June, the efforts of the good samaritans turned out to be a total success, reported CNN Travel.

The restoration team believes that the refurbished Marree Man would last longer than its original version.

According to NASA, "They [the team] created wind grooves, designed to trap water and encourage the growth of vegetation. They hope that eventually, the man will turn green."

In a previous article, CNN reported that an entrepreneur by the name of Dick Smith took upon himself to unravel the geoglyph's mystery in 2016. His team combed through all the available evidence but couldn't find anything conclusive.

In 2018 he even offered a 5,000 Australian dollar reward for anyone who knows the identity of its creator.

Nobody turned up with an answer but it was speculated that unknown artist lives in Alice Springs or even might be an American.

New Delhi, Jun 18: Vodafone Idea on Thursday told the Supreme Court that it has incurred Rs 1 lakh crore losses as it insisted it is not in a position to furnish bank guarantees.

A bench comprising Justices Arun Mishra, S. Abdul Nazeer, and M.R. Shah, taking up the adjusted gross revenue (AGR) matter through video conferencing, directed the telecom companies to submit their financial documents and books for the last 10 years.

Asking Vodafone if it was a foreign company, the bench said that how can the company say it would not furnish any bank guarantee.

"What if you fly away overnight in future without paying anything?" it asked.

Senior advocate Mukul Rohatgi, representing Vodafone Idea, denied his client is a completely foreign firm and cited before the bench its tie-ups and investments.

Vodafone owes over Rs 58,000 crore as AGR dues and so far, has paid close to Rs 7,000 crore.

Rohatgi contended before the court that the telecom company is in a tough situation, and cannot furnish any fresh bank guarantee, as profits have eluded the company in past many quarters. He submitted before the bench that Rs 15,000 crore bank guarantees are lying with the government, and his client's losses are over Rs 1 lakh crore.

"I cannot offer any more surety," he informed the bench.

Justice Mishra noted that this is public money and these dues should be recovered. "Do not tell us that you will pay if you were to make profits... the money must come," he noted.

Justice Shah observed that the telecom industry is the only industry which earned during the Covid-19 pandemic. "After all, this money will be used for public welfare", he said.

Rohatgi argued that his client would have to fold up if orders were issued to clear dues tomorrow. "11,000 employees will have to go without notice, as we cannot pay them," he added.

Senior advocate Abhishek Manu Singhvi, appearing for Bharti Airtel, contended before the court that out of Rs 21,000 crore AGR dues, the company has already deposited a sum of Rs 18,000 crore.

He argued that his client has given a bank guarantee, in excess of demand, to DoT, and supported the proposal for phased repayment of remaining AGR dues. He insisted that the company needs to sit down with the government and calculate the dues. Airtel owes Rs 25,976 crore after paying Rs 18,000 crore, as per the government.

Senior advocate Arvind Datar, representing Tata Telecom, informed the bench that his client has paid Rs 6,504 crore in AGR dues so far, and furnishing a bank guarantee may adversely impact investments in the sector.

The total AGR dues are close to Rs 1.5 lakh crore.

The top court will now take up the matter in the third week of July.
