Hydrogen is a highly inflammable substance and explosive in nature; it cannot be easily transported from one place to another and it can be generated by the hydrolysis of water but it is a very expensive process.Hydrogen used in the fuel cells is a very flammable gas and can cause fires and explosions if it is not handled properly. Hydrogen is a colorless, odorless, and tasteless gas. Natural gas and propane are also odorless, but a sulfur-containing (Mercaptan) odorant is added to these gases so that a leak can be detected.There's virtually no pure hydrogen on Earth because it's so reactive. Most hydrogen is made from methane [natural gas] in a process that produces carbon dioxide and other greenhouse gases. Hydrogen can also be made from water using electrolysis, but that requires electrical energy.
Why is hydrogen not a good fuel : Hydrodgen is highly explosive : Using it as domestic fuel is very dangerous, because even a small spark can cause ucontrolled combustion leading to huge explosions. It does not burn at a slow rate. Transport of hydrogen is very difficult.
Why hydrogen is not the future
One major issue is the inefficiency of producing and storing hydrogen fuel. The process of creating hydrogen gas through electrolysis or reforming natural gas requires a significant amount of energy, often derived from non-renewable sources.
How safe is hydrogen fuel : While no fuel is 100 percent safe, green hydrogen has been shown to be safer than conventional fuels in a multitude of aspects. Hydrogen is not toxic, unlike conventional fuels. On the other hand, many conventional fuels are toxic or contain toxic substances, including powerful carcinogens.
Hydrogen is non-toxic, but in indoor environments like battery storage rooms, it may build up and cause asphyxiation by displacing oxygen. This danger can be offset to some extent by adding odorants to hydrogen fuel, giving it an artificial smell and alerting users in case of a leak.
The hydrogen is useful in the human body as it helps the human body to keep hydrated, and also, the correct proportion of hydrogen and oxygen forms water.
Why is Elon Musk against hydrogen
"It's just that, unlike Musk, it's not my own investment." Musk has panned hydrogen as a practical fuel source for vehicles many times. Its low density means it would require a highly pressurized "gigantic fuel tank," making it a "big pain in the ass," he said on a Tesla earnings call in January 2021.A number of hydrogen's properties make it safer to handle and use than the fuels commonly used today. For example, hydrogen is non-toxic. In addition, because hydrogen is much lighter than air, it dissipates rapidly when it is released, allowing for relatively rapid dispersal of the fuel in case of a leak.The reason why hydrogen is inefficient is because the energy must be transferred from wire to gas and then back to wire in order to power a car – known as the Energy Vector Transition. As an example lets take 100 watts of electricity produced by a renewable source such as a wind turbine locally.
Hydrogen Council/McKinsey (October 2022): Green hydrogen will be able to be produced in 2050 at under $1.15/kg $1.15/kg in the US, China, the Middle East, South America, Namibia and South Africa, but $1.80-2.50 in Europe, Japan and South Korea.
Is hydrogen expensive as a fuel : Is it cost-prohibitive for potential everyday drivers or industrial users” The short answer is, “No, at least not long term.” While hydrogen may be slightly more costly than other fuel sources today, experts predict that those prices will drop dramatically in the coming years.
Does hydrogen always leak : Meanwhile, emissions rates for storing and transporting hydrogen as a liquid vary wildly, with projected leakage during handling ranging from 2-20%. Liquefaction is estimated to leak between 0.15-10%, while transporting liquid H2 via trucks could leak 2-13.2%.
Is hydrogen bad for your lungs
Conclusions. Hydrogen gas inhalation improves lung function and protects established airway inflammation in the allergic asthmatic mice model which may be associated with the inhibition of oxidative stress process. This study provides a potential alternative therapeutic opportunity for the clinical management of asthma …
Re: Is it safe to inhale hydrogen gas Hydrogen can be an asphyxiant by displacing the oxygen in the air. However, for the volume of hydrogen needed to do that in a normal sized room, the bigger issue would be explosion risks. For a MRE, the amount of hydrogen produced is very small and will quickly dissipate.In addition to the anti-oxidative and anti-inflammatory effects of H2, it also plays an anti-apoptotic role against nerve damage. H2 suppresses the expression of Bax, caspase-3, and caspase-12, promotes the expression of Bcl-2 and Bcl-xL, and increases the Bcl-2/Bax ratio in the brain [9, 37, 42, 48, 101, 103, 107].
What does hydrogen do to your lungs : In I/R-induced ALI, hydrogen inhibits inflammation and oxidative stress, inhibits apoptosis of lung tissue, and alleviates lung injury caused by lung transplantation and other causes. Hydrogen can also alleviate ALI caused by various other factors.
