Holcim OLYMPUS | Greece

Every Bright Spot is an opportunity to inspire the next wave of progress. 

Holcim’s €400M OLYMPUS project in Greece is building a direct source-to-sink CCS value chain in the Mediterranean to capture 1 Mtpa of CO2 from an isolated cement plant.

Bright Spot | Holcim OLYMPUS

Holcim’s OLYMPUS project is testing a new model for cement decarbonisation in a challenging setting. By building a direct source-to-sink CO₂ value chain in the Mediterranean Sea, it is redefining how to tackle regulatory, financial and infrastructure hurdles outside of established industrial clusters.

OLYMPUS is one of Southern Europe’s most advanced CCS projects, designed to capture one million tonnes of CO₂ annually from Holcim’s Milaki cement plant and store it offshore in the Prinos depleted oil field. The project uses a combination of oxyfuel and cryogenic technologies and benefits from a deep-sea port terminal, enabling direct source-to-sink CO₂ shipping.

Unlike cluster-based CCS models, OLYMPUS pioneers a standalone configuration, which simplifies
logistics but increases infrastructure costs. The plant is also unique in its export orientation,
producing specialised cement for oil and gas drilling and serving a growing low-carbon demand in
Greece.

We have 50+ CCUS projects in development worldwide, of which 11 flagship projects. 7 European projects have been awarded grants from the EU Innovation Fund; these are planned to be operational by 2030.

Holcim OLYMPUS

OLYMPUS is one of Holcim’s most advanced CCS projects under development in Europe and a core part of its 2050 net-zero vision. It will capture 1 Mtpa of CO2 from Holcim’s Milaki cement plant in Greece, and store it in the offshore Prinos concession, a depleted oil field.

Mission Possible Partnership | MPP

Mission Possible Partnership (MPP) is an independent non-profit organisation advancing global clean industry transformation. Since 2019, we have been working with some of the most energy-intensive industries: aluminium, aviation, cement, chemicals, shipping and steel, to cut their nearly 25% of global GHG emissions. ​

We mobilise business, finance, government and civil society leaders to speed up the shift to clean materials, chemicals and fuels. Having charted sectoral pathways to net-zero, we continue to forge new territory, lifting the barriers to enable a critical mass of clean industrial projects to break ground by 2030.

Industrial Transition Accelerator | ITA

The ITA is a global multi-stakeholder platform -managed by Mission Possible Partnership – to fast-track decarbonisation across heavy-emitting industry and transport sectors.  It aims to significantly grow the pipeline of commercial-scale, clean industrial projects to reduce emissions by 2030.

Build Clean Now | BCN

Build Clean Now is a global campaign bringing together governments, companies and finance to accelerate the pace at which clean industrial projects are financed and built, year-on-year. It is led by the Industrial Transition Accelerator (ITA) and Mission Possible Partnership (MPP).
