Neuss aluminium plant — Germany

Neuss aluminium plant is an aluminium smelter in Germany. Its listed capacity is 150,000 t of alumina/aluminum. Aluminium smelters use large electric currents to refine alumina into molten aluminium above 900°C, and the hot metal must flow through crucibles and casting equipment. It is operated by Hydro Aluminium Deutschland GmbH. By capacity it ranks #1 among 5 aluminium smelters in Germany. It emits about 298,613 t CO₂e a year from Climate TRACE. That is 0.26% of the CO₂e from the 118 facilities in Germany that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 5% below the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-3673049.

In context: how this facility compares

At 150,000 t of alumina/aluminum, Neuss aluminium plant is well above the median aluminium smelter in Germany (67,000 t of alumina/aluminum). Subsector: aluminum. As aluminium smelter, it requires high process heat (typically 600–900°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Aluminium smelters use large electric currents to refine alumina into molten aluminium above 900°C, and the hot metal must flow through crucibles and casting equipment.

Local climate

Neuss aluminium plant sits in a temperate oceanic climate zone (Köppen Cfb), at 51.1°N in the northern hemisphere.

Köppen zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).

Site climate & environmental severity

This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1393 W/m² to ambient — roughly 1.07× the loss at a 20 °C reference. Reference-surface calculation at a 150 °C surface from WorldClim climate normals (ASTM C680 / ISO 12241) — an indicative per-climate comparison, not a measurement of this site’s specific equipment. Open method dataset: DOI 10.5281/zenodo.20787408 (CC BY 4.0).

Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
