Swedish combustion technology SME specializing in thermoacoustic instability and hydrogen burner stability for industrial decarbonisation.
SONTECH AB is a small Swedish combustion technology company specializing in thermoacoustics — the interaction between heat release, pressure oscillations, and sound in industrial burners and gas turbines. They operate as an industry host partner in Marie Skłodowska-Curie training networks, meaning they provide PhD researchers with access to real combustion rigs, industrial boiler systems, and hands-on experimental environments that university labs cannot replicate. Their work sits at the intersection of acoustic engineering and industrial combustion, with a clear recent pivot toward hydrogen fuel combustion and the stability challenges that come with decarbonising gas-fired equipment. For businesses and researchers, they represent a rare combination: a small company with deep technical specialization and direct access to industrial test infrastructure.
POLKA (2019-2023) explicitly lists thermoacoustic instability and flame flashback as core topics, indicating hands-on expertise with combustion oscillation control in gas turbines and boilers.
POLKA keywords include hydrogen combustion and decarbonisation, suggesting SONTECH AB is repositioning toward H2-ready burner technology as the industrial energy transition accelerates.
SmartAnswer (2017-2020) focused on mitigating flow-induced acoustic radiation for aircraft and surface transport, placing SONTECH in the broader field of aeroacoustics and vibration management.
POLKA's explicit mention of boilers alongside gas turbines signals that SONTECH AB works with real industrial combustion hardware, not only laboratory-scale setups.
In their first H2020 engagement (SmartAnswer, 2017–2020), SONTECH AB contributed to transport-sector noise and vibration problems — flow acoustics in aircraft cabins and vehicle bodies, a domain where combustion and aeroacoustics overlap. By their second project (POLKA, 2019–2023), the focus had shifted decisively toward combustion stability under the pressure of the energy transition: hydrogen fuel, thermoacoustic instability, flame flashback, and decarbonisation of gas turbines and boilers. The thread connecting both periods is acoustics in high-energy flow environments, but the application domain has rotated from transport to industrial energy infrastructure.
SONTECH AB is moving toward hydrogen-ready combustion systems and thermoacoustic control for decarbonised industrial burners — a direction that aligns directly with the EU's push to replace natural gas with hydrogen in heat-intensive industries.
SONTECH AB participates exclusively as a third-party host in MSCA Innovative Training Networks rather than as a named beneficiary — this means they open their facilities and expertise to doctoral researchers without receiving direct EC funding, a deliberate choice that signals they value the talent pipeline and research access more than grant income. They work within large multi-partner consortia (35 unique partners across 13 countries from just two projects), but their role is consistently that of an industrial anchor providing real-world experimental grounding. Partnering with them likely means gaining access to operational combustion test infrastructure in Sweden and a practitioner perspective that balances academic research with industrial constraints.
Despite only two H2020 projects, SONTECH AB has touched 35 unique consortium partners across 13 countries — a footprint explained by the large, multi-institutional nature of MSCA training networks, which typically involve 10–15 academic and industrial nodes per consortium. Their network is pan-European with a natural academic-industrial mix typical of combustion and acoustics research communities.
SONTECH AB occupies a specific niche that is hard to find: an industrial SME with enough technical depth in combustion acoustics to be invited as a training host by competitive European research consortia, but small enough to be agile and directly accessible. For a consortium builder, they provide the "industry reality check" role — PhD students trained partly at SONTECH AB gain exposure to real burner hardware and operational constraints, not just simulation tools. For businesses exploring hydrogen boiler conversion or gas turbine combustion stability, SONTECH represents a technically credible small partner with European research network connections.
