For many, hydrogen is the fuel of the future. New research raises doubts

Published

According to a new assessment from the’s International Agency for the Prohibition of Chemical Weapons, hydrogen fuel may be worse for the climate than previously assumed.

Many people believe that hydrogen, the most abundant substance in the universe, will be the clean energy of the future. However, a new peer-reviewed study questions its effectiveness in reducing greenhouse gas emissions, which are the primary cause of catastrophic global warming. The most significant stumbling block: The majority of hydrogen used today is derived from natural gas, a process that consumes a lot of energy and produces a lot of CO2.

The natural gas sector has advocated absorbing carbon dioxide in order to make hydrogen that is free of emissions. However, according to a new study, even that fuel releases more pollution along its whole supply chain than simply burning natural gas. “To term it a zero-emissions gasoline is completely incorrect,” says the study’s main scientist. Researchers from Cornell and Stanford Universities collaborated on the article, which was published in the journal Energy Science & Engineering.

The researchers used the estimate that 3.5 percent of the gas extracted from the earth leaks into the atmosphere, based on accumulating evidence that natural gas drilling produces significantly more methane than previously thought. They also factored in the amount of natural gas needed to run the carbon capture equipment. The greenhouse gas footprint of blue hydrogen was more than 20% higher than that of natural gas or coal when used for heating.

According to a new assessment from the Department of Energy, hydrogen is more efficient than natural gas in the long run. Findings like these could change the equation for hydrogen, which is used to power cars, heat houses, and power plants. The natural gas sector has been extensively advertising hydrogen as a reliable, next-generation fuel in recent years.

Hydrogen may one day be used for energy storage or to power certain modes of transportation. However, there is a growing consensus that a larger hydrogen economy based on natural gas could be harmful to the environment. According to Drew Shindell, a professor of earth science at Duke University, the recent study added to the evidence. He was the lead author of a United Nations research released this year that indicated that reducing methane, the major component of natural gas, is significantly more important than previously assumed in combating global warming.

According to a McKinsey & Company estimate, hydrogen energy might produce $140 billion in yearly income by 2030 and sustain 700,000 jobs. By 2050, hydrogen may cover 14% of worldwide energy consumption, according to the study. “The possibility of continuing to use fossil fuels with something extra put on as a potential climate solution is neither properly accounting for emissions nor making realistic assumptions” about future costs, according to the report.

The most recent bipartisan infrastructure bill allocates $8 billion to the development of regional hydrogen hubs. Environmentalists have slammed the funding, calling it a “fossil fuel subsidy.” Some Democrats, such as Maryland Rep. Jamie Raskin, have criticized the notion, calling it an “empty promise.” A solar-powered hydrogen pilot plant has been proposed by NextEra Energy in Florida.

Green hydrogen, as the industry calls it, would eventually have to be produced using renewable energy. Electrolyzing water to extract hydrogen atoms from oxygen is a time-consuming and energy-intensive process. Because there isn’t enough renewable energy to produce large amounts of hydrogen today, very little of it is green. The National Fuel Cell Research Center’s director, Jack Brouwer, explains, “First we utilize blue, then we make it entirely green.”

The majority of hydrogen fuel will be produced from natural gas using a polluting and energy-intensive steam reforming process. Carbon capture and storage technology, which includes absorbing carbon dioxide before it is discharged into the atmosphere, is used to create blue hydrogen. However, the natural gas used to make hydrogen, power steam reforming, and drive the CO2 collection system is not included. “Those are significant,” says Cornell’s Dr. Howarth.

According to an Entergy spokesman, hydrogen is “part of establishing a long-term carbon-free future.” Hydrogen integration is being researched by National Grid, Stony Brook University, and New York State. According to a methane expert, more scientists are beginning to look into some of the industry’s assertions about hydrogen. According to the Department of Energy, there are no plans to create or use hydrogen in the near future.

According to National Grid, hydrogen will play a significant role in the coming decades, with renewable energy being the cornerstone. According to a representative for New York State, the state was “exploring all technologies,” including hydrogen, to help meet its climate goals. She claims that the state’s researchers will “examine and consider the blue hydrogen paper.”

Apple will give PC makers sleepless nights with MacBooks’ new computing direction

Apple-comes-up-with-new-direction-for-Macbook-Marksmen-Daily

Steve Jobs built Apple on a formula of enduring simplicity and usability. With products that are approachable, and easy-to-use for seven and seventy-year-olds alike, it created a user base that is as extensive as it is fiercely loyal.

This simple, ‘it just works’ approach is reflected in the company’s culture as well, and can be seen in the software underpinning its gadgets, such as iOS. As a result, iOS is one of the world’s most popular operating systems, and dead easy to use. All Apple devices run the same software, something no other business has yet accomplished. When we consider Apple’s main competitor, Android, we see that it is more complicated and fragmented than iOS, with updates sometimes taking months to roll out. This combination of technology with simplicity, creativity and design, has been Apple’s secret sauce for success for the longest time.

Not one to rest on its laurels, Apple has upgraded its product lines for the second month in a row. After the Apple iPhone and a portion of the iPad series were updated last month, it was now time for Apple’s Mac and AirPods to be updated. Apple not only unveiled the new Apple MacBook Pro 14, but also updated the MacBook Pro 16 after a long hiatus during its ‘Unleashed’ keynote. With the arrival of the Apple M1 Pro and Apple M1 Max processors, the entire Mac line-up is looking to level up in the coming months.

“M1 Pro and M1 Max take Apple silicon even further, and are unlike anything else in a pro notebook,” says Johny Srouji, Senior Vice President of Hardware Technologies at Apple. “With massive gains in CPU and GPU performance, up to six times the memory bandwidth, a new media engine with ProRes accelerators, and other advanced technologies, M1 Pro and M1 Max take Apple silicon even further, and are unlike anything else in a pro notebook.” According to Apple, the M1 Pro boasts a 16-core GPU that is up to 2x quicker than the M1 and up to 7x faster than the integrated graphics on the current Windows 8-core PC laptop chip.

For the first time, the MacBook line-up has two options that offer exactly the same series of features and specs. Both will get the M1 Pro and the M1 Max chips. The MacBook Pro 16-inch and an all new 14-inch join the existing MacBook line-up. The 16-inch variant is 16.8 mm thick while the 14-inch option is 15.5 mm thick, and the new design language adds rounded edges. Less reliance on dongles too, with the HDMI port, an SD card slot, headphone jack with Hi-Fi audio support and more Thunderbolt ports.

Apple has made some big statements about the new MacBooks’ battery life. They say that the 14 inch MacBook Pro can play video for up to 17 hours, and the 16 inch variant can play video for up to 21 hours.

When we look from this window, although there are many companies in our age, there is no other company that offers the depth and breadth of expertise Apple brings to the table. Another feature of Apple is that it intelligently extends its product range and range. With its latest product boasting a power-packed punch, Apple is well poised to take on all comers for some more time yet.

5G-Technology-Marksmen-Daily

According to a recent CII-Deloitte paper titled ‘Digital reset — Touching a billion Indians,’ technological breakthroughs with 5G could reshape the future of communication in India.  

India is making a big contribution to the next generation of telecom services, with enterprises partnering to widen options. Shortly, private networks are projected to witness a surge in demand from businesses in fields such as healthcare, education, finance, e-commerce, and entertainment.  

“Telecom has played a critical role in causing a shift in consumer behavior. According to Peeyush Vaish, Partner and Telecom Leader at Deloitte India, “data availability has pushed more and more digital services to the end-user.” 

However, India’s telecom sector still faces significant challenges on the route to the 5G rollout. “The government, telecom regulators, telecom service providers (TSPs), and original equipment manufacturers (OEMs) must collaborate,” Vaish said, citing poor fiberization, local hardware production, high spectrum costs, and the selection of appropriate 5G standards and bands as important challenges.

But even beyond the bones of infrastructure and networking that defines these technological advances, there is a story to be told beyond mere connectivity. India’s great mass huddles in its hinterland, and 5G, or even lesser forms of connectivity, have been levers of great social growth and upliftment, impacting our communities like never before. While the industry can be referred to in colder terms as a ‘service enabler’, the honest truth is that it is a democratiser par excellence, a lever for social equity that is truly once-in-a-generation. Digital India has laid the platform for a lot of these advances, and India Inc. too is playing a part in scripting this growth story. Through a continued collaboration of government and industry, India can hope to leapfrog its growth trajectory to an altogether new level on the back of this telecommunications push.

Can fuel cells be a better option than EVs?

Fuel-cells-an-alternative-to-EV-Marksmen-Daily

As the automobile world is moving its focus to electric vehicles, traditional names like Tata Motors to new-age technology companies like Ather Energy and Ola are throwing their hat into the ring with an array of mobility solutions. As pollution levels touch extraordinary levels and the impact of climate change starts to make itself all the more apparent, a new wave of mobility seems to be taking root. 

Why FCEVs?

Every automobile enthusiast celebrated the introduction of EVs. Battery Electric Vehicles (BEVs) were the first EVs to hit the market. Despite their merits, these cars are not a viable alternative to Internal Combustion Engines (ICE) based vehicles because they have a limited range-per-charge capacity and are reliant on external charging facilities.Fuel Cell Electric Vehicles, or FCEVs, can overcome this shortcoming and prove to be a better alternative to traditional ICE vehicles. 

FCEVs do not require external charging and instead use a fuel such as hydrogen to create the electricity needed for driving and to charge the built-in batteries for auxiliary functions. FCEVs, like ICE-based vehicles, will require gasoline, but it will be a green fuel that will not pollute the environment. What’s more, they do not produce noxious exhaust fumes; their only by-product is pure, distilled water, making it a clean, green mobility solution that can serve us all.

So when can I drive one? 

Although FCEVs are not yet present in India, they have been tested. National Thermal Power Corporation (NTPC), the country’s largest power provider, had encouraged the automobile industry to procure such vehicles for experimental projects in 2021.  

According to news sources, the project has caught the interest of major automakers Toyota and Hyundai Motor, as well as Indian companies Tata Motors, Ashok Leyland, and KPIT Technologies. Because their powerplants are so specialized, FCEVs are also much costlier to build than regular gas-powered cars, causing a bit of a catch-22 situation, as consumers are waiting to jump on this bandwagon once ownership costs get rationalised and the refueling infrastructure gets created. Automobile companies, on the other hand, are holding their cards close to their chest as they try to understand if there’s enough consumer interest to warrant the hefty investments FCEVs demand. This is a Mexican standoff that will go on for some time yet.
