Both HEMPT-NG (2017-2021) and HEMPT-NG2 (2021-2023) develop successive generations of the High Efficiency Multistage Plasma Thruster as coordinator.
THALES DEUTSCHLAND GMBH
German Thales division developing next-generation HEMPT electric plasma thrusters with green propellants for European satellite propulsion independence.
Their core work
Thales Deutschland is the German arm of the Thales group, and in the H2020 space programme it acts as the European developer of the HEMPT (High Efficiency Multistage Plasma Thruster) family — electric propulsion engines used to keep satellites in orbit and move them between orbits. Their engineering work covers plasma physics, magnetic confinement, cathode design and propellant chemistry, including the switch away from xenon toward alternative and "green" propellants. They build hardware that is qualified for flight, not just lab demonstrators, which puts them among the handful of European suppliers able to provide non-dependent satellite propulsion.
What they specialise in
Green propellants and alternative propellants appear as top keywords in both HEMPT projects, reflecting a push away from xenon dependence.
Magnetic plasma confinement, plasma diagnostic and plasma modelling are recurrent keywords across both projects.
High current cathode appears as a keyword in HEMPT-NG, where cathode design is a critical thruster subsystem.
Dual mode operation appears in both projects; erosion free thruster (HEMPT-NG) and high lifetime (HEMPT-NG2) signal a shift toward endurance.
European non dependence is a lead keyword in both HEMPT-NG and HEMPT-NG2, aligning with EU strategic autonomy in space.
How they've shifted over time
They are moving a specific hardware line from prototype maturity toward flight-ready, long-life European satellite propulsion, which makes them a credible industrial partner for space missions needing non-US, non-xenon electric thrusters in the second half of the decade.
How they like to work
Thales Deutschland has led both of its H2020 projects as coordinator and has not joined any consortium as a junior partner, which tells you they bring their own technology agenda and set the pace of the work. Across the two projects they worked with 11 unique partners in 5 countries — a small, tight consortium model typical of space hardware development, where the same engineering, propellant and test partners tend to carry over from one generation to the next. Expect a partner that runs the show but integrates specialised suppliers around a clearly defined product.
A compact network of 11 partners across 5 European countries, focused on space-propulsion subsystem expertise rather than broad geographic spread. The footprint is clearly continental European, consistent with the "non-dependence" objective that frames both projects.
What sets them apart
Very few European organisations coordinate successive generations of a qualified electric-propulsion thruster under EU funding — Thales Deutschland is one of them, which gives them an unusual combination of plasma physics depth and industrial flight-hardware credibility. Unlike university labs working on isolated plasma experiments, they carry a specific product line (HEMPT) forward from one H2020 call to the next. If you need a European partner who can take an electric propulsion concept from plasma modelling all the way to a lifetime-qualified engine, this is a short-list organisation.
Highlights from their portfolio
- HEMPT-NGTheir largest H2020 project at EUR 1.93M, establishing the core next-generation thruster design with erosion-free architecture and alternative propellants.
- HEMPT-NG2Direct follow-on (2021-2023) that shifts the emphasis to high lifetime and endurance, showing a deliberate multi-phase EU roadmap rather than one-off funding.
