Today we have a responsibility to take initiatives, to anticipate

From the outset, Dos Grados has been working to respond to the challenges posed by the energy transition.

Thus, in addition to our diversified portfolio of sustainable real assets in renewable electricity generation projects, we are also committed to other growth areas aligned with our sustainability strategy, which contribute to a fair and effective ecological transition.

Energy storage

We can’t manage the sun and the wind, but we can maximise the integration of renewable energies by promoting storage.

Retaining energy

Retaining energy and using it in a controlled way will be essential in the near future. We can’t manage the sun and the wind, but we can maximise the integration of renewable energies by promoting storage.

Storage systems can only be developed counting with determined regulatory support and the appropriate consideration in networks planning.

Storage also represents an opportunity for technological leadership, strengthening the industry, creating jobs and reducing external energy dependence.

What is energy storage?

Technology for storing excess renewable energy and being able to supply it when needed at times of low production or high demand.

It is a key pillar for the energy transition and the decarbonisation of the electricity system. Renewable energies – non-manageable as we cannot manage when it’s sunny or windy – require storage systems to avoid curtailing clean energy at times of low electricity demand. Therefore, an improvement in the way energy is stored is of crucial importance to support these technologies.

Main systems

The main energy storage systems are pumped hydro, thermal storage, lithium batteries and green hydrogen.

Green hydrogen

Hydrogen could become the main fuel of the future because it is affordable and versatile.

Hydrogen decarbonisation

Hydrogen decarbonisation is a clean and non-polluting process with multiple applications in industry. As it is storable and versatile in terms of use, it could become the main fuel of the future..

At Dos Grados we are sure that proper regulation will speed up the implementation of this technology, which will reduce our global energy dependence and help achieve European and national goals. For this reason, we collaborate with the Castilla-La Mancha Hydrogen Cluster in the strategic development of this energy driver, to promote and support initiatives that are committed to decarbonising the economy.

Or what is green hydrogen?

It’s a renewable gas produced from renewable energy through a process called water electrolysis. It emits no CO2, is clean and very versatile.

Electrolysis is the process of breaking down the water molecule into separate hydrogen and oxygen atoms, in this case from renewable electricity.

Green hydrogen applications

In the coming years, green hydrogen will represent an important part of our energy mix, helping to make the economy more sustainable and curb climate change.

  • Clean industrial fuel. Use as a raw material to replace grey hydrogen produced using natural gas, which involves CO2 emissions.
  • Sustainable mobility. Production of emission-free synthetic fuels for conventional engines and electric vehicles: heavy, rail, sea and air transport.
  • Storage of surplus renewable energy.

At Dos Grados we are currently analysing opportunities in other energy transition areas related to electro-intensive consumption, such as water management, data centres or recycling.
