![]() ![]() There was no helium at all, as helium does not form compounds, so was not retained in any form, and what helium exists now is a by-product radioactive decay of larger elements, with almost 5 billion years of radioactive decay meaning we now have some helium on Earth too, but nothing like the average for the Universe. The only hydrogen which was retained on earth, was hydrogen chemically attached to other, heavier elements, in chemical compounds, and that hydrogen is around 0.1% of the Earth. During formation, the Earth was is not sufficiently massive to retain free hydrogen (or even helium, the next lightest) because these gases are so lightweight, so instead of being 98% hydrogen and helium like the universe overall, the earth started out with zero free hydrogen and helium, as both floated off into space. Hydrogen is element number 1, and the lightest element in the universe. ![]() So Hydrogen is not as abundant here on Earth as some sources suggest. But most of the universe is also colder than 200 degrees below zero, so clearly “most of the universe” is not how things are here on Earth.Įarth is only around 0.14% Hydrogen, with Oxygen (47%), Silicon (28%), Aluminium (8%) and Iron (5%) are the most common elements here on Earth. ![]() Yes, hydrogen is the most abundant element in the universe, at around 70% of all regular matter (regular as in ignoring dark matter) and hydrogen and helium together account for 98%. To quote Monty Python: “ there is bugger all down here on Earth“. The Universe is around 70% hydrogen, but the Earth is 0.14% hydrogen, and what hydrogen there is, in bound into compounds requiring energy for extraction. Abundance Myth.ĭespite hydrogen being the most abundant, and lightest, element in the Universe, there is no huge supply here on Earth. This exploration provides looks at the reality, and the myths about hydrogen, and provides background for other pages such as: Electric or Hydrogen Cars and Hydrogen Scams. ![]() blue/grey hydrogen, the fossil fuel industries’ hope for greenwashing emissions.‘green’ hydrogen, not a source of energy, but a less efficient storage stepping stone on the path to battery power.There is much talk of a ‘hydrogen economy’, but what is the substance behind it all? There are many myths but hydrogen can be : Rapid radical change for the industry, but it will take longer to impact consumers. Keys factor in EV trends during 2023 could turn out to be who is ‘cool’, shifting perceptions of a climate threat and the need for rapid response, and the impact of conflicts such as Ukraine. Not only are the ‘legacy’ automotive companies GM, Ford, VW and Toyota competition for the hearts and dollars from consumers, but also BYD, who is already taking the EV lead from Tesla. Some are predicting it will lose half of the remaining value in 2023, and although others predict the stock price will rebound, both outcomes are possible, and which becomes reality could depend very much on whether Tesla can remain ‘cool’, or through Musk and twitter becomes linked to far right.Īlthough entire EV future is not dependant solely on Tesla, a decline could have wide implications, for the market, competitors and the global transition to EVs. The world of EVs is changing, as is the leadership. ![]()
