A study reveals that hydrogen generated by renewables will have a lower cost per kWh in 2040. According to a study carried out by the Brainpool Institute from Germany, ordered by Greenpeace, the hydrogen generated by renewable energies will resist the gas before the middle of the century, since the prices of the kWh of the first would increase to exceed 150% of the current cost, going from 0.02 € to 0.035 €.

In the case of hydrogen produced from renewable energies, it would be the reverse, from 0.15 € to 0.03 € and finally to 0.02 €. For experts, the costs of “green hydrogen” are high, between production and financing support for the production of energy from renewable sources in Germany, it can cost € 0.38 per kWh; However, with some changes, the price is expected to gradually drop to meet the forecast before 2040.

Legislate to promote the use of renewable energies.

The Greenpeace organization pointed out that the “Wind gas, hydrogen would be less expensive than the fossil alternative, when it becomes essential to guarantee supply in a renewable system”. However, to conform to the premise, the organization remembers that “The federal government must create the conditions necessary for the development of the technology of this” wind gas “in the current legislature”.

Encouraging the use of “green hydrogen” is one of the objectives set for the reduction of CO2 and carbon dioxide emissions, as well as for the development of renewable energy sources in other sectors, for which they ask for the necessary incentives for investment.

According to the Organization, the demand for renewable hydrogen is high in all economic sectors; Electricity, wind gas, can be stored in large quantities in the gas network, in addition to ensuring security of supply.

Only with wind gas as the storage technology, the dark periods, that is, the phases with little wind and sun, could be shortened up to two weeks at a relatively reasonable cost.

Reduction of CO2 in the environment as a premise.

It should be noted that the reduction of CO2 emissions is a priority, for example in the aeronautical or maritime sector, in the chemical industry or in the production of steel.

The areas that can have an energy transition so far are very small, which is why they offer the option of “ green hydrogen ” as a viable option to replace fossil fuels, in addition to being able to be used as a base for renewable fuels or chemicals such as fertilizers or plastics.
