Liquified Natural Gas- LNG
Natural Gas - The contemporary fuel
Hydrogen is the ultimate green fuel. It is the most abundant element in the universe. It provides three times more energy than fossil fuels and releases pure water as the only byproduct. It is also one of the leading options for storing energy from renewables promising to be the lowest-cost option for storing electricity over days, weeks, or even months. The element is neither new nor novel. The first experiments took place way back in the 1800s and it was used as a fuel in Apollo I that landed on the moon in July 1969. Yet, the availability of cheap fossil fuel meant hydrogen energy never really picked up. The fact that hydrogen does not occur naturally as a gas on the Earth — it is always combined with other elements such as water (H2O) — added to the problem. This is because an external energy source is required to isolate hydrogen. At present coal or fossil fuels are used to isolate hydrogen almost everywhere. This is called grey hydrogen and it is as polluting as fossil fuel.
Countries are now waking up to the idea of replacing fossil fuels with renewable sources to isolate green hydrogen. This shift is happening because of two reasons. Firstly, there are clear signs that fossil fuels can no longer be used to meet the world’s energy needs. Given the limited supply of rare metals to make EV batteries, hydrogen will soon play an indispensable role in delivering zero-emission transport. The natural abundance of hydrogen means it has the potential to level competition in the automotive sector, whereas the supply of raw materials for EV batteries is controlled by a few large players. The International Renewable Energy Agency (IRENA) suggests the share of hydrogen in the 2050s energy mix should reach 12 percent from almost zero right now. It says 66 percent of the hydrogen to be used in 2050 needs to be green.
