The Italian system: from a EUR 280/MWh tariff for plants up to 1 MW, through the gap after 2016, to FER 2 (EUR 233/MWh for biogas up to 300 kW) and minimum guaranteed prices for older biogas plants.
On 25 June 2026 the European Commission announced the Biomethane Mechanism – a free platform matching buyers and suppliers, a dashboard of national rules and an investment conditions tool. Registration opened on 18 June; the first round was then announced for September (see the update).
CHP availability, methane yield from VS, OLR, HRT, FOS/TAC, own consumption and heat utilisation: a set of indicators with formulas, response thresholds and an example of a monthly report.
One of the first Czech biogas plants ends its support period on 21 August 2026. The municipality expects revenue to fall by at least 2 million Kč a year and criticises the modernisation conditions.
The EU requires 55, 60 and 65% preparation for re-use and recycling of municipal waste by 2025, 2030 and 2035, and landfilling below 10% by 2035. We set the targets against Eurostat data for Poland.
From 12 June to 12 July 2026 the New Zealand environment ministry is consulting on options to reduce emissions from organic waste; of 41 class 1 landfills only 18 have gas capture.
727 MW volume, 637 MW of bids, 491 MW of awards after a cut to 80%. Average 18.46 ct/kWh. Biomethane: 6 bids, all winning, average 23.08 ct/kWh.
Indirect land use change (ILUC) is the risk that energy crops displace food production. We explain how RED treats food and feed crops, waste and residues, and intermediate crops.
A POB report compares the macroeconomic effects of gas imports and domestic biomethane production: 1 billion m³ of gas costs about PLN 1.52 billion from imports versus about PLN 5.53 billion for biomethane, which feeds domestic firms, farmers and budgets.
From 1 April 2026 the PMG for biogas, biomass and bioliquids are subject to limits on hours and spending; ARERA, with Resolution 174/2026 of 19 May 2026, updated the formulas for fixed costs.
What the cost of running a biogas plant consists of: substrates, CHP servicing, own energy, labour, insurance, digestate. How to calculate the cost per kWh and per m³ CH₄ and where to look for savings.
The EBA report "Digestate in Europe: State of Play in 2026" estimates the value of digestate at more than EUR 1 billion per year. Technically it could replace more than 16% of nitrogen, up to 30% of phosphorus and up to 10% of potassium from mineral fertilisers.
Acidogenesis and acetogenesis convert the products of hydrolysis into acids, hydrogen and acetate. We explain why these stages depend on cooperation with methanogens and what their disruption means for the operator.
A biogas plant is liable administratively, civilly and criminally: for waste, emissions, the register of agricultural biogas producers, water and construction. We review the main penalty regimes and how to defend yourself.
Osaka Gas reported that since February 2026 it has been testing in Nagaoka (Niigata) an e-methane plant built with Inpex and has begun injecting synthetic gas into the grid. The plan: 1% in fiscal year 2030.
The German EUR 5 billion aid scheme in the form of carbon contracts for difference (15 years) supports fuel switching in industry; the technologies named include biomethane, electrification, hydrogen, CCS and heat recovery.
Japan has about 1000 municipal waste incinerators, of which about 40% generate electricity. An analysis of environment ministry data for fiscal years 2022–2024.
Biogenic CO₂ from biogas upgrading is easy to capture and can be permanently stored (BECCS). We discuss the chain, costs, the role of CCS and the EU framework for certifying CO₂ removals.
An analysis of the Quebec regulation forcing a share of RNG in distributed gas: 1% from 2020, interim targets and 10% in 2030 (according to IEDM 2032 in brackets), and discrepancies over the timetable and delivery.
An overview of several documented projects: 6 MW of landfill gas at Nejapa (El Salvador), a 1 MW installation at a wastewater treatment plant in Managua, a small CHP unit in Costa Rica and the first biomethane installation in Cuba — and conclusions on scale.
According to the CIBiogás Biogas Panorama 2025, about 1,803 biogas installations operate in Brazil, and production is approaching 5 billion Nm³ a year; a 5% rise in number and 6% in volume.
On 21 April 2026 the EBA published a report: biomethane potential in Europe in 2030 is 34–35 billion m³ (less than previously), 116–132 billion m³ in 2040 and up to 205 billion m³ in 2050. The reason: projects are being launched too slowly.
The inside of a digester, a digestate tank or a manhole is a confined space in which people die. The procedure step by step: permit, ventilation, measurements, standby person, rescue.
On 14 April 2026 the European Commission approved a Czech aid scheme worth EUR 3.7 billion: two-way contracts for difference for 15 years, a target of 350 million Nm³ of biomethane by the end of 2030, competitive tenders.
