European Union and Germany pave the way for CO2 removal from the atmosphere through Hydrothermal Carbonization
For years, the carbon offset market was dominated by questionable providers who made big promises, generated high profits, but delivered little real climate impact. To restore trust and ensure genuine CO₂ removal, the EU has now introduced binding rules for carbon offsetting and carbon dioxide removal.
Alongside the switch to renewable energy and low‑carbon industrial processes, permanent CO₂ removal from the atmosphere is indispensable for meeting global climate targets (IPCC AR6, 2023). In this context, biochar from pyrolysis and especially hydrothermal carbonization (HTC) of organic residues into hydrochar have already proven to be safe, efficient, and energy‑saving methods of CO₂ sequestration.
A New Era for Carbon Removal: The Game-Changing Potential of Hydrothermal Carbonization
With Regulation (EU) 2024/3012, the EU and Germany are establishing a forward‑looking, competitive framework that rewards the most effective and sustainable carbon capture and storage solutions. HTC, as a mature and scalable technology, is ideally positioned to play a central role in this new carbon removal landscape.
A Pioneering Legal Framework
For the first time, carbon dioxide removal (CDR) will be embedded in a comprehensive legal structure that is technologically neutral yet demands strict quality standards, including:
- Precise quantification – robust, measurable, and verifiable CO₂ capture.
- Additionality – ensuring genuine climate benefits beyond existing obligations.
- Long-term storage – durable, secure CO₂ retention over generations.
- Sustainability – adherence to high environmental and resource‑efficiency criteria.
Hydrothermal Carbonization: A Breakthrough in CO₂ Sequestration
HTC converts wet organic residues into a stable carbon product, turning potential greenhouse gas sources into a permanent carbon sink. Key advantages include:
Permanent and transparent CO₂ storage; The resulting biocoal (hydrochar) stabilizes carbon in a form comparable to lignite, enabling safe, long‑term storage in existing fossil coal seams under continuous monitoring and verification.
Substantial reduction of greenhouse gas emissions; Transforming manure, sewage sludge, digestates, and biowaste into biocoal prevents emissions of CO₂, methane, and nitrous oxide.
Outstanding energy efficiency; HTC requires only a fraction of the energy input per ton of CO₂ removed compared to direct air capture (DAC), making it both climate‑ and cost‑efficient.
Support for the circular economy: Valuable nutrients such as nitrogen and phosphorus can be recovered during HTC and reused as regenerative fertilizers, strengthening sustainable agriculture.
Decentralized and scalable implementation: HTC plants can be deployed regionally, reducing transport emissions and creating local economic value.
Seizing the Opportunity: From Regulation to Real Impact
The scientific reality of climate change is unaffected by political denial: rising greenhouse gas concentrations are driving higher global temperatures and more extreme weather events. With a solid regulatory foundation now established at the European level, there is a unique opportunity to develop HTC into a powerful and profitable pillar of climate protection.
Companies, investors, municipalities, and policymakers should act now—by expanding HTC capacity, integrating it into waste and energy systems, and building business models around durable, verifiable CO₂ removal. The framework is in place; it is time to turn hydrothermal carbonization into both a climate solution and a sustainable economic opportunity.
