German Biogas Sector Faces Triple Squeeze: New Security Laws, EU Methane Rules, and a Major Overhaul of Feedstock
Published on 07/22/2026 at 12:52 | Redaktion boerse-global.de
Brandenburg has become the first German state to let operators of critical energy infrastructure deploy their own drone-defence systems and video surveillance, a move that breaks with the long-standing principle that such powers rest solely with state authorities. The state’s interior ministry announced the draft law in July, citing a rise in sabotage attacks on power, gas and water facilities. Until now, companies running biogas plants and other critical installations had to rely on police or federal agencies for aerial threat protection.
The security shift is just one of several pressures reshaping Germany’s biogas industry in 2026. Operators are simultaneously grappling with a planned overhaul of the Renewable Energy Sources Act (EEG 2027), new EU methane-emission rules, and mandatory cyber-risk assessments that will take effect in 2027 under the EU Machinery Regulation 2023/1230.
Industry associations have reacted with alarm to the EEG 2027 draft, warning that proposed tender volumes are too low to sustain investment in existing plants. Without clear incentives for flexible operation, they argue, Germany could lose significant amounts of firm capacity — the baseload power that biogas currently provides when wind and solar are unavailable. The draft has drawn particular criticism for failing to offer a pathway for plant modernisation.

At the European level, the European Commission is reportedly planning to delay enforcement of sanctions under the methane regulations that took effect in May 2024 until 2027. Environmental groups have labelled the three-year grace period a watering-down of the rules. Industry representatives counter that practical implementation clauses are essential to avoid disrupting operations.
On the technical side, the sector is adapting to new safety standards. Explosion protection (ATEX) and corrosion resistance must now be assessed separately for gas-handling components, manufacturers stress. One example cited in industry guidance is the e4MSMOR side-channel compressor, rated at 1.5 kW, which moves 138 m³/h at 250 mbar overpressure. For inter-stage gas transport between fermenters, storage tanks and upgrading units, more powerful models delivering up to 263 m³/h are required — provided they meet ATEX classifications such as II 3GD T3. Experts emphasise that equipment selection always demands a project-specific review of process data.
Workplace safety has also come under scrutiny following rescue drills conducted in July at waste-treatment and sewage plants. Simulations of retrieving unconscious workers from underground basins confirmed the acute risk of oxygen deficiency. Emergency responders are now calling for mandatory multi-gas detectors and specialised ventilation gear during maintenance on digestate storage tanks.
The pressure to modernise is visible in concrete projects. The Höingen plant must undergo a comprehensive expansion by the end of 2028 to comply with EEG requirements. Plans include new fermenters, gas storage units and more powerful engines, driven by a shift in feedstock away from maize toward triticale and slurry. Similarly, the Rosien facility is investing in biomethane upgrading equipment to feed directly into the natural-gas grid — a strategy that operators see as the only way to secure profitability beyond 2030.

Cyber-security obligations are tightening in parallel. The EU Cyber Resilience Act (CRA) and the Machinery Regulation will together mandate cyber-risk assessments for all new installations from 2027. Technical publications from the VDE, Germany’s association for electrical, electronic and information technologies, are already preparing companies for the requirements, which are closely linked to the CRA’s product-safety framework.
