Would Electricity Need To Have Hmrc Tax & Duties As High As For Fossil Fuels When Cars Are Electric And Planes Are Run By Liquefied Hydrogen (Which Need Electricity To Produce)
71 Answers
Everyone wants clean environment to live in. New technologies, education & governmental incentives & legislation can help to curb pollution of carbon dioxide, plastics, smog, toxins, etc. Banning the sale of cars run solely on fossils fuels by 2040 is an example of governmental incentives & legislation to curb pollution.
About half of all fossil fuels had been burnt since the industrial revolution & has given raise nearly a degree centigrade rise in global temperatures. Thus if the rest of fossil fuels are burnt a total of about 2 degree centigrade rise will be likely. Hotter air can cause extreme climate. Global warming of around 2 degrees centigrade will cause increased coastal flooding, as well as more drought & famine - turning agricultural land into desert (in an era of exponential population rises).
Apparently, UK experimental SABRE (Synergistic Air-Breathing Rocket Engine) ram jet engine is capable of single-stage-to-orbit capability at over Mach 5.2 (3,800 mph). SABRE engines burns hydrogen with atmospheric oxygen and when the space plane reaches an altitude of around 16 miles and five times the speed of sound (i.e. Mach 5), it switches to its onboard liquid oxygen tank to reach orbit. Being in orbit, such a craft can travel in opposite direction to the rotation of the earth thus saving energy & time of travel.

The only viable source of Hydrogen is the splitting of water, H2 0, into Hydrogen and Oxygen by electrolysis

Earth atmosphere only contain trace quantities of hydrogen gas. To produce hydrogen gas industrially, hydrolysis of water is the best. Chemical reactions (like using acids and salts) do not produce industrial quantities of hydrogen and will be more expensive, as well as wasting scarce chemicals.

Developing nuclear fusion to generate electricity commercially is the holy grail of limitless energy supply of the future & is the energy source of billions of stars in the universe. Unlike nuclear fission, fusion does not produce long-lived radioactive end products.
Nuclear fusion fuse deuterium (hydrogen with 2 neutrons) & tritium (hydrogen with 3 neutrons) to form helium atoms in a plasma at temperature 10 times (100 million degrees C) that in the sun's core - by utilising‘magnetic confinement' (as plasma) of gaseous deuterium & tritium with strong magnets. Only plant components become radioactive & will be safe to recycle or dispose of conventionally within 100 years.
Deuterium is plentiful in seawater & tritium obtained by reacting neutrons with lithium. Advantages of nuclear fusion include no long-lived radioactive wastes.

ToraToraTora: "why waste electricty stripping hydrogen out of water? better to use the electricity directly"
Ram & jet engines need stream of host gases to propel the rocket/plane forward - burning hydrogen can achieve this, it will be very hard (if not impossible) to produce stream of hot gases with electricity!

// For that reason I practically lose the will to live halfway through reading them so rarely respond.// someone
but with her dying breath - she has ! ha!
I get the same lack of a will to live with some of the answers....
take the best answer fr'instance
"The only viable source of Hydrogen is the splitting of water, H2 0, into Hydrogen and Oxygen by electrolysis.
Hydrolysis ? photolysis ?
"If we can supply the electricity for the electrolysis from solar ,wind, tidal power we really will have unlimited 'free' power."
erm hold on - why don't we use the electricity from solar etc...
and miss out the the hydrolysis step which of course DOESN'T add power thro something called the 2 law of thermodynamics - but there will be a waste ( entropy and all that - second law again since the process isnt reversible)
"There are other problems such as developing batteries that can store the power , but they are solvable."
but so far havent been solved for a hundred years
If you take Volta as the get-go of a battery or 'voltaic' cell
then make that two hundred
other than that as they say I cant find much to moan about with the 'best answers'

yup
didnt spot this answer - deffo correcticus - scientific basis is 2nd law of thermodynoamics
if you get more out of electrolysis then you have constructed an infinite energy machine and even Sadi Carnot ( Réflexions sur la puissance motrice du feu, ) a dit "Non mais Non!" in oo 1832 I think

PP, ToraToraTora, eddie,
For those in doubt, as every GCSE student will tell you a process called 'Electrolysis of water' produce Hydrogen. Check http://
Of course, electricity can be lost as heat (as a result of resistance, producing gaseous oxygen, as well as gaseous hydrogen, etc) during electrolysis, as extra energy cannot be created thermodynamically (except by nuclear fusion/fission under E=MC2).
