CCS and CCUS in Switzerland: Study Highlights Need for Action

On behalf of scienceindustries, BAK Economics and the German Energy Agency (dena) have conducted the first in-depth analysis of carbon capture and storage (CCS) in Swiss hazardous waste incineration plants (HWIP), presenting concrete data and involving affected companies directly. The study fills an important knowledge gap, as no quantitative insights into the economic conditions for CCS in this sector had previously been available.

The findings show that CCS plays a crucial role in reducing emissions that are technically difficult to avoid – especially in HWIPs and certain chemical and pharmaceutical production processes. The study analyses investment and operating costs for 2030 and 2050, identifies the main cost drivers (notably transport and storage), and compares them to projected CO₂ prices under the emissions trading system.

The conclusion is clear: without targeted political support, CCS will not be economically viable. The study identifies Carbon Contracts for Difference (CCfDs) as a particularly promising support tool, as they can cover not only capital and operating expenses but also transport and storage costs. Examples from Germany, Denmark, and the Netherlands show how this model can be successfully implemented.

This study provides a solid, evidence-based foundation for political dialogue – and for developing effective solutions that allow Switzerland to advance climate action and industrial progress hand in hand.
