Green hydrogen: an alternative that reduces emissions and cares for our planet
Decarbonizing the planet is one of the goals that countries around the world have set for 2050. To achieve this, decarbonizing the production of an element like hydrogen, giving rise to green hydrogen, is one of the keys as this is currently responsible for more than 2 % of total global CO2 emissions.

This technology is based on the generation of hydrogen — a universal, light and highly reactive fuel — through a chemical process known as electrolysis. This method uses an electrical current to separate the hydrogen from the oxygen in water. If this electricity is obtained from renewable sources we will, therefore, produce energy without emitting carbon dioxide into the atmosphere.

Hydrogen is the most abundant chemical element in nature. As noted by the IEA, the global demand for hydrogen for use as a fuel has tripled since 1975 and reached 70 million tonnes a year in 2018. In addition, green hydrogen is a clean energy source that only emits water vapour and leaves no residue in the air, unlike coal and oil.

This energy source has pros and cons that we must be aware of. Let's go over some of its most important good points:

100 % sustainable: green hydrogen does not emit polluting gases either during combustion or during production.
Storable: hydrogen is easy to store, which allows it to be used subsequently for other purposes and at times other than immediately after its production.
Versatile: green hydrogen can be transformed into electricity or synthetic gas and used for commercial, industrial or mobility purposes.
However, green hydrogen also has negative aspects that should be borne in mind:

High cost: energy from renewable sources, which are key to generating green hydrogen through electrolysis, is more expensive to generate, which in turn makes hydrogen more expensive to obtain.
High energy consumption: the production of hydrogen in general and green hydrogen in particular requires more energy than other fuels.
Safety issues: hydrogen is a highly volatile and flammable element and extensive safety measures are therefore required to prevent leakage and explosions.
Hydrogen as a fuel is a reality in countries like the United States, Russia, China, France and Germany. Others like Japan are going even further and aspire to become a hydrogen economy. Below we explain what the impact will be in the future:
Electricity and drinking water generator
These two elements are obtained by reacting hydrogen and oxygen together in a fuel cell. This process has proved very useful on space missions, for example, by providing crews with water and electricity in a sustainable manner.

Energy storage
Compressed hydrogen tanks are capable of storing energy for long periods of time and are also easier to handle than lithium-ion batteries because they are lighter.

Transport and mobility
Hydrogen's great versatility allows it to be used in those consumption niches that are very difficult to decarbonise, such as heavy transport, aviation and maritime transport. There are already several projects under way in this area, such as Hycarus and Cryoplane, which are promoted by the European Union (EU) and aim to introduce it in passenger aircraft.

In its commitment to driving the energy transition, Iberdrola is leading the development of green hydrogen with more than 60 projects in eight countries (Spain, United Kingdom, Brazil, United States, among others) to respond to the needs of decarbonisation. As it did with renewables 20 years ago, the company has become a 'first mover' in this new technological challenge that involves the production and supply of green hydrogen.
Iberdrola is already developing several projects that will enable the decarbonisation of industry and heavy transport in Spain and the United Kingdom, as well as developing its value chain. The company has a mature project portfolio of 2,400 MW by 2025 and expects to produce 350,000 tonnes of green hydrogen per year by 2030. In addition, Iberdrola has submitted 54 projects to the Next Generation EU programme, which would trigger investments of €2.5 billion.

               hydrogen is not a panacea and comes with it's own problems. It should be used reservedly.
