Spanish geoscience consulting SME specializing in subsurface modelling for nuclear waste safety, CO2 storage, and environmental contaminant transport.
Amphos 21 is a Barcelona-based environmental and geoscience consulting firm specializing in subsurface modelling, geochemical simulation, and safety assessment for nuclear waste disposal and CO2 storage. They provide technical expertise in reactive transport modelling, groundwater contamination, and mineral resource management. Their work bridges fundamental geochemistry with applied engineering — from predicting how radioactive waste packages behave over millennia to optimizing mineral carbonation for carbon capture. They also deliver lifecycle assessment (LCA) and sustainability consulting for the mining and raw materials sectors.
Core contributor across Cebama (cement barriers), DISCO (spent fuel dissolution), ENTRUST (nuclear trust-building, as coordinator), PREDIS (pre-disposal management), and EURAD (European joint programme).
Modelling expertise demonstrated in CarbFix2 (CO2 mineralization), METAL-AID (subsurface remediation), FluidNET (crustal fluid migration), and Cebama (cement barrier evolution).
CarbFix2 focused on in situ carbon mineralization economics, while early keywords show deep involvement in onshore/offshore CO2 injection and air capture modelling.
Contributed to SCRREEN and SCRREEN2 (critical raw materials expert networks), ITERAMS (integrated mineral technologies), and e.THROUGH (sustainable mining and recycling).
PANORAMA (rare earth element environmental transfer and bioavailability) and METAL-AID (metal oxide subsurface remediation) show growing focus on pollutant behaviour in natural systems.
CoPerMix (control and prediction of mixing processes) represents a newer application of their transport modelling capabilities to industrial mixing.
In their early H2020 period (2015–2018), Amphos 21 focused heavily on CO2 geological storage — modelling impure CO2 injection, mineral carbonation, and offshore/onshore storage safety — alongside nuclear waste barrier materials (Cebama) and raw materials supply chains. From 2019 onward, their work shifted decisively toward radioactive waste management (PREDIS, EURAD) and environmental transport modelling (PANORAMA on rare earth pollutants, FluidNET on crustal fluids), while maintaining their raw materials involvement through SCRREEN2. The evolution shows a consulting firm deepening its nuclear safety portfolio while broadening from geological CO2 storage into wider environmental geochemistry applications.
Amphos 21 is consolidating as a go-to modelling partner for Europe's radioactive waste disposal programmes while expanding into environmental contaminant fate — expect them to pursue deep geological repository and critical minerals sustainability projects.
Amphos 21 overwhelmingly participates as a partner rather than leading consortia, having coordinated only 1 of 16 projects (ENTRUST). They operate comfortably in large, multi-country research networks — 238 unique partners across 32 countries indicates they are well-connected generalists rather than a closed-circle operator. Their frequent role as a third party (4 projects) suggests other consortia actively seek their specialist modelling skills even when they are not formal consortium members.
With 238 unique consortium partners across 32 countries, Amphos 21 has one of the broadest collaboration networks for an SME of its size. Their partnerships span Western and Northern Europe heavily, reflecting the geography of nuclear waste and raw materials research programmes.
Amphos 21 occupies a rare niche as a private SME with deep expertise in both nuclear safety assessment and geological resource modelling — domains typically dominated by large research institutes and national laboratories. Their ability to deliver advanced reactive transport simulations as a commercial service makes them an accessible, flexible partner without the overhead of institutional bureaucracy. For consortium builders, they bring credible modelling capability with a track record across nuclear, CO2 storage, and mining — a combination few single organisations can offer.
