Energy and fibre-optic network group Andel is investing 75 million DKK in Stiesdal Storage Technologies. Their ambition is to take stone-based energy storage to a new level. The green transformation is in full swing, and greater amounts of energy are being produced sustainably, in such forms as wind power and solar power.
It is developed by the Danish company Stiesdal Storage Technologies (SST), and the GridScale demonstration plant will be the largest electric storage facility in Denmark with a capacity of 10 MWh. Read more about the Danish company which is
With the first 2 MW, 10 MWh GridScale demo plant on the way for installation in early 2022, the team of Stiesdal Storage Technologies and Atlas Copco Gas and Process is ready to serve the market with an affordable solution for medium-term storage of electrical energy.
Stiesdal A/S''s GridScale hot-rock energy storage system, which uses crushed stones to store heat for between ten hours and ten days, is due to be trialled at a solar array in Denmark. Siemens Gamesa is developing a similar technology, which stemmed from Stiesdal''s initial design idea when he was chief technology officer at Siemens Wind Power.
• Li-ion battery storage systems are too expensive for large -scale renewable energy integration. The good news: • Storage technologies exist that can fill the gap • Thermal storage for days to weeks • Hydrogen storage using amonia as carrier for seasonal storage. We just need to industrialize and implement!
GridScale is a pumped heat energy storage system, using crushed rock as an abundant, low-cost storage medium. The system''s main components: A turboexpander unit with pre-pressure compressor, controls etc. A filter unit with air filters and manifolds. Two rows of standardized storage reservoirs.
We take great pride in our work and in the fact that our solutions make a real difference on a global scale. Currently we have activities in Power-to-X hydrogen production, carbon capture and storage combined with green fuel production, floating offshore wind, and energy storage. We are equally ambitious when it comes to our company as a workplace.

Lolland to become a hub for hot rock energy storage The energy and fibre-optic group Andel and Stiesdal has decided to place a new en-ergy storage facility at Rødby, an ideal location when it comes to removing the barriers to the green transition. Odense, 2 September 2021 Rødby can look forward to becoming the home of a new energy storage
Henrik Stiesdal (born April 14, 1957) is a Danish inventor and businessman in the modern wind power industry. In 1978, he designed one of the first wind turbines representing the so-called "Danish Concept" which dominated the global wind industry through the 1980s. [1] Until 2014, Stiesdal was the chief technology officer of Siemens Wind Power.During his professional

One of these is energy storage. Stiesdal Storage Technologies'' GridScale battery provides thermal storage of electrical energy, which promises to make wind and solar power more viable by offering a solution to the fluctuations in the energy supply they produce. Stiesdal is also seeking to tackle the problem of jet fuel emissions through SkyClean
According to an article in Wind Power Monthly, the storage module will be "capable of producing energy for up to 24 hours." The lack of thermodynamically costly energy conversions in the Siemens system accounts for its superior round-trip energy efficiency. However, Stiesdal said, the ammonia "storage system as such is very low cost."

The first electrolyzer for European Energy''s hydrogen production facility in Maade, Esbjerg, is going to be supplied by Stiesdal – a Danish climate technology company. European Energy and Stiesdal subsidiary Stiesdal Hydrogen have entered into an agreement on testing a new 3 MW electrolyzer developed by Stiesdal Hydrogen.

European Energy’s commitment to clean energy aligns perfectly with our mission at Stiesdal, and we look forward to producing sustainable hydrogen at Maade with the first generation of our HydroGen Electrolyzer, says Peder Nickelsen, CEO at Stiesdal Hydrogen.
The electrolyzer will be installed at European Energy’s hydrogen facility in Maade, Esbjerg. Stiesdal Hydrogen’s electrolyzer is based on conventional alkaline electrolysis with a novel, integrated design.
Stiesdal Hydrogen’s electrolyzer is based on conventional alkaline electrolysis with a novel, integrated design. The support systems (water treatment, power supply and cooling) are fully modularized, and the complete system is well suited for low-cost industrial manufacturing.
The electrolyzer supplied by Stiesdal Hydrogen will be able to produce roughly 270 tons of hydrogen a year when fully operational. – With its innovative take on proven alkaline electrolysis, we find that Stiesdal Hydrogen is one of the most promising electrolyzer manufacturers today.
The European energy storage market is booming with Germany leading residential adoption (+58% YoY) thanks to €500/kWh subsidies. Italy's new tax credits drive 5.2GWh commercial deployments, while UK grid-scale projects exceed 8GWh with 2-hour duration systems. Key selection criteria: German-certified safety (VDE-AR-E 2510), 10+ year warranties, and VPP readiness. Top-performing products include Sonnen's hybrid inverters (98% efficiency) and BYD's Blade Battery (12,000 cycles @80% DoD). For snowy regions like Scandinavia, consider Huawei's -30°C compatible systems. France mandates carbon footprint declarations - Sungrow's ISO-14067 certified solutions gain preference.
For European homeowners, 5-10kWh systems with 3-phase compatibility are ideal. Top picks: 1) Tesla Powerwall 3 (13.5kWh, 97% round-trip efficiency) for smart home integration; 2) LG Chem RESU Prime for compact urban installations; 3) SMA Sunny Boy Storage for retrofit projects. Critical features: EU-made battery cells (exempt from CBAM tariffs), dynamic tariff optimization (like Octopus Energy integration), and fire-safe LiFePO4 chemistry. Southern Europe demands 85%+ depth of discharge capability, while Nordic markets require -25°C operation. Always verify CEI 0-21 compliance for Italian grid connection and EnWG certification for German feed-in.
