CALIDA CLEANTECH GMBH

Their core work

Calida Cleantech is a German SME working on advanced thermochemical conversion of biomass and waste into energy, with a growing focus on integrating carbon capture and CO2 utilization into those processes. Their core work involves gasification systems — turning solid feedstocks into syngas — coupled with gas cleaning technologies such as ceramic filters and tar catalysts to produce clean, usable energy carriers. In HiEff-BioPower they contributed to a highly efficient, fuel-flexible combined heat and power (CHP) system based on fixed-bed updraft gasification. In GICO they extended this into full-cycle decarbonization, pairing gasification with CO2 capture and conversion routes including power-to-gas, methanol synthesis, and solid oxide fuel cells (SOFCs).

What they specialise in

How they've shifted over time

Calida Cleantech entered H2020 through a bioenergy efficiency angle — HiEff-BioPower (2016) was about squeezing more power and heat out of biomass via flexible CHP, with no recorded keyword detail suggesting a fairly focused engineering contribution. By the time GICO started in 2020, their scope had broadened considerably: the keyword set spans the entire value chain from wet-biomass pre-treatment (hydrothermal carbonization) through gasification and gas cleaning to CO2 capture, conversion, and end-use in fuel cells. The direction is clear — from standalone bioenergy efficiency toward integrated carbon-negative energy systems where every output stream (heat, power, CO2) is captured and valorized.

Calida is moving toward full-cycle decarbonization systems where gasification is the front end of a broader carbon-negative value chain — a strong fit for future calls on industrial decarbonization, bioenergy with carbon capture (BECCS), and synthetic fuel production.

How they like to work

Calida has participated exclusively as a consortium partner — never as coordinator — across both projects, which is consistent with a specialist SME that brings specific technology or process know-how rather than project management infrastructure. With 18 distinct partners across 7 countries from just 2 projects, they engage in relatively large, multi-partner RIA consortia rather than small bilateral collaborations. This suggests they are comfortable operating inside complex research networks and contributing a defined technical workpackage.

Calida has built a network of 18 unique partners spanning 7 countries through two projects, indicating active engagement in broad European consortia rather than narrow bilateral ties. No repeated partnership patterns are detectable from just 2 projects, but their European reach is genuine.

What sets them apart

Calida sits at a rare intersection: an SME small enough to be agile but technically deep enough to contribute to frontier RIA research on thermochemical conversion and carbon capture. Their combination of gasification engineering, gas cleaning hardware knowledge, and emerging CO2 utilization capabilities makes them a credible bridge between biomass energy and industrial decarbonization — a niche most large industrials address only partially. For consortium builders, they offer practical cleantech development capacity without the overhead of a large research institute.

Highlights from their portfolio

• HiEff-BioPower
  Their largest project by EC funding (€529,450), focused on fuel-flexible biomass CHP — a commercially relevant technology with direct route to market for district heating and industrial heat customers.
• GICO
  Represents a significant technical leap — integrating gasification with CO2 capture and conversion into methanol and power-to-gas, placing Calida inside one of the most strategically important decarbonization technology clusters in Horizon 2020.
