GP JOULE presents itself at the new energy trade fair Volta-X in Stuttgart from 28 to 30 March

Reußenköge/Stuttgart, 28 March 2023

Intelligent energy solutions are the theme of the Volta-X Energy Systems Expo from 28 to 30 March in Stuttgart: Moving away from fossil fuels, towards regional, flexible units based on renewable energies. In hall 9, stand 07, GP JOULE will be showing how renewable energies can be linked to the industrial, heating and mobility sectors. Learn more about how we are leading businesses and communities into a green future and ensuring stable prices and a long-term supply with renewables.

"GP JOULE stands for a meaningful connection between energy production from the sun and wind and the consumers' demand for electricity, heat and mobility," says Heinrich Gärtner, co-founder and CTO of GP JOULE. "We can show what opportunities are available when you intelligently link up the sectors with each other from a practical point of view. That's why the energy turnaround company is heading its own trade fair appearance with the hashtags #ZUSAMMENdenken, #ZUSAMMEN planen and #ZUSAMMENmachen (thinking together, planning together, acting together).


The three-day trade fair, which is co-organised by the German Federal Association of Energy Storage Systems (BVES), will be stimulated by various networking formats and an exciting conference programme, in which top-class speakers from GP JOULE will participate and share their expertise.



For example, at the panel discussion "Future Energy Systems" on the opening day, Tuesday, 28 March, from 4.15 pm. In the Volta-X Arena, Heinrich Gärtner, among others, will discuss technologies and options for action for achieving a sustainable and affordable energy supply.


The following day, on Wednesday 29 March at 11.50 am, Heinrich Gärtner will speak about "Integrated energy systems: upgrading, converting and using sustainable electricity as a central element of the energy turnaround" in the Volta-X Arena.


Also on Wednesday, 29 March, at 1.00 pm, Christian Rosskopf, Head of GP JOULE CONSULT, will present "eFarm - the largest sustainable hydrogen mobility project in Germany" in the Best Practice Arena.


After all, the key to a successful energy turnaround lies in holistic utilisation concepts and the close technical link-up to the areas of mobility, industry and households. The basis for this is electricity generated from wind power. Electrolysis ensures that renewables can be integrated into the system more quickly, independently of how fast the grid is expanding. The green hydrogen produced in this way serves as storage and forms the fuel for industry and transport, and the heat generated during hydrogen production can flow into a heating network and be used for heating. The hydrogen mobility project eFarm delivers all these elements.


Those who cannot attend the fair in person have the opportunity to watch lectures via live stream ( Among others, Lena-Marie Brenner, team managerfor developing renewable cross-linkage and heat projects at GP JOULE, willtalk about "Renewable heat supply, the price-stable energy solution for municipalities" in the Volta-X Studio on Tuesday, 28 March, from 11 am.
