Hydrogen fuel specialist pumps £2 million into first refuelling station in Scotland, July 28, 2021
Hydrogen element serial#
Hydrogen is not widely used as a fuel now, but it has the potential for greater use in the future.Led by serial entrepreneur and former European Space Agency engineer Tim Harper, and fuel cells and hydrogen technology expert Brendan Bilton, Element 2 has identified Aberdeen, Dundee and Glasgow as focal points for establishing its Scottish refuelling network. However, hydrogen is useful as an energy source/fuel because it has a high energy content per unit of weight, which is why it is used as a rocket fuel and in fuel cells to produce electricity on some spacecraft. It takes more energy to produce hydrogen (by separating it from other elements in molecules) than hydrogen provides when it is converted to useful energy. Hydrogen has the highest energy content of any common fuel by weight (about three times more than gasoline), but it has the lowest energy content by volume (about four times less than gasoline). Hydrogen can be produced-separated-from a variety of sources including water, fossil fuels, or biomass and used as a source of energy or fuel. Hydrogen, like electricity, is an energy carrier that must be produced from another substance. Hydrogen is an energy carrierĮnergy carriers allow the transport of energy in a usable form from one place to another. Hydrogen is a gas at normal temperature and pressure, but hydrogen condenses to a liquid at minus 423 degrees Fahrenheit (minus 253 degrees Celsius).
