Central to both FLEXnCONFU (small ammonia reactor) and ARENHA (advanced reactors for energy storage through ammonia)
PROTON VENTURES BV
Dutch SME engineering small-scale ammonia production plants and ammonia-based energy storage and combustion systems for the green energy transition.
Their core work
Proton Ventures is a Dutch engineering SME specialized in small-scale ammonia production technology and ammonia-based energy solutions. They bring industrial expertise in Haber-Bosch reactor design, ammonia synthesis, and ammonia combustion systems to EU research consortia. Their work spans the full ammonia energy chain — from green ammonia production via electrolysis to ammonia use as a fuel in power plants and combustion engines. They also contribute to smart port decarbonization through ammonia-based energy storage and fuel applications.
What they specialise in
FLEXnCONFU addresses hydrogen and ammonia combustion in power plants; ARENHA explores ammonia combustion engines
FLEXnCONFU focuses on power-to-ammonia and power-to-hydrogen; ARENHA works on SOEC electrolysis for ammonia electrosynthesis
MAGPIE project applies ammonia and hydrogen solutions to smart green port infrastructure near their Schiedam base
ARENHA involves solid oxide electrolysis and fuel cell technology for ammonia production and reconversion
How they've shifted over time
Proton Ventures entered H2020 in 2020 with a focus on integrating ammonia into existing power infrastructure — flexible combined-cycle plants, power-to-X-to-power roundtrip systems, and emission reduction through ammonia combustion. By 2021, their focus shifted toward the underlying production technology: advanced electrochemical methods (SOEC, membranes, electrodes), electrosynthesis pathways, and ammonia combustion engines as standalone applications. This progression shows a move from system-level integration toward deeper materials and reactor engineering for the ammonia economy.
Proton Ventures is deepening its position in the green ammonia value chain, moving from application-level integration toward core production technology and electrochemical conversion — positioning them as a go-to SME partner for ammonia economy projects.
How they like to work
Proton Ventures operates exclusively as a participant, contributing specialized ammonia technology expertise to larger consortia rather than leading projects. With 75 unique partners across 12 countries in just 3 projects, they work within large, multi-national consortia (averaging 25+ partners per project). This pattern suggests they are sought after as a niche technology provider — the kind of partner consortia recruit specifically for ammonia engineering capability.
Despite only three projects, Proton Ventures has built a broad European network of 75 partners across 12 countries — a reflection of the large-scale energy and transport consortia they participate in. Their base near Rotterdam port connects them naturally to maritime and port-related energy initiatives.
What sets them apart
Proton Ventures occupies a rare niche as an SME with hands-on industrial capability in small-scale ammonia plant design and construction — not just research, but actual reactor engineering. While many academic partners study ammonia theoretically, Proton Ventures brings the practical know-how to build and operate ammonia systems. For any consortium needing a partner who can move ammonia technology from concept toward real-world deployment, they fill a gap that universities and large corporates typically cannot.
Highlights from their portfolio
- ARENHATheir largest project (EUR 752,950) covering the full ammonia energy storage chain from SOEC electrosynthesis to combustion engines — their deepest technical involvement
- FLEXnCONFUAddresses the critical challenge of making gas power plants flexible using ammonia and hydrogen as alternative fuels, directly relevant to Europe's energy transition
- MAGPIEApplies their ammonia expertise to port decarbonization — a natural fit given their Schiedam (Rotterdam area) location and an indicator of cross-sector versatility
