Power-to-X: Using renewable power to produce green fuel

Power-to-X technologies make it possible to store renewable energy in a variety of forms. As the energy system transitions to renewables, they are becoming an essential complement to battery systems. Not only does Power-to-X supply carbon-neutral fuel for buildings, industry, power plants and vehicles, it also enables long-term storage of energy, for example by producing green hydrogen (Power-to-Gas).

But Power-to-X systems are only environmentally friendly if they rely on renewable power. For example, electrolysis can use excess solar or wind energy to break down water into oxygen and hydrogen. The hydrogen can then be burned directly as fuel, stored or processed further to produce methane. The advantage: The gases can be distributed and stored using existing infrastructure and also help reduce CO2 emissions.

Power-to-X

For an example of Power-to-X in action, look no further than the SmartQuart project in the municipality of Kaisersesch in Rhineland-Palatinate. With funding from the German Federal Ministry for Economic Affairs and Energy, project partners there are building a sustainable hydrogen infrastructure, which includes a hydrogen-based microgrid. Nearby photovoltaic and wind power installations supply the energy needed for hydrogen production and new LOHC technology enables the transport or long-term storage of partial quantities of the hydrogen produced. A system of pipes transports the hydrogen to end users.

As a key component of the complete transition from fossil fuels to renewable energies, Power-to-X technologies are in the spotlight at ees Europe for the second time in a row. Numerous themed joint booths, exhibition forums and the accompanying Power-to-X Conference offer visitors the opportunity to learn more.
