In Brody (the Agricultural Experimental Farm of the Poznań University of Life Sciences) a research biomethane plant with a capacity of 0.499 MWe has been built, producing about 650,000 m³ of biomethane a year as bioCNG. Technological start-up began at the end of 2024.
In February 2025 the Australian parliament passed the Hydrogen Production Tax Incentive: AUD 2 per kilogram of renewable hydrogen for up to 10 years for projects from 2027–28 to 2039–40.
On 6 February 2025 the Sejm passed an amendment to the Act on Biocomponents and Liquid Biofuels: a National Indicative Target of 9.2% in 2025, 10% in 2026–2029 and 14.9% in 2030. Biomethane, including from the grid, counts towards the target.
Why digestate is separated into a solid and a liquid fraction, which technologies are most commonly used and how to calculate the mass and nutrient balance using an example.
H2 2024: RDN PLN 456.5/MWh, 3× operation PLN 667.6/MWh. From 28 December a new 200 kW threshold and every negative hour outside support.
A review of three Japanese studies on the methane potential of rice straw, manure and food waste: BMP from 1999, co-digestion of feed rice (2012) and solid-state thermophilic co-digestion (2022).
A guarantee of origin for gas from RES is issued by the President of URE, but the application is submitted to the grid operator or an accredited body. Deadlines, validity, redemption and differences from certificates.
CNG buses running on bioCNG can reduce fuel-cycle emissions and improve air quality, but electric buses are gaining the advantage. We compare emissions, fuel costs and the role of the Clean Vehicles Directive.
In January 2025 the Treasury and the IRS published final regulations for the 45V credit: qualifying hydrogen may not exceed 4 kg CO₂e/kg H₂, and the full USD 3/kg applies below 0.45 kg.
On 18 December 2024 Korea announced a phased reduction of REC weights for biomass: state-owned utilities lose certificates for co-firing from 2025, private ones from 2026. Domestic forest biomass keeps its weights.
From 1 January 2025 ships above 5,000 GT calling at EU ports must progressively reduce the GHG intensity of the energy they use. BioLNG is one of the fuels that help meet this requirement.
On 1 January 2025 the EU obligation to collect textile waste separately came into force. It is another stream, after bio-waste, covered by separate collection, which affects the layout of the waste management system.
Digestate is an organic fertiliser of variable composition. What it contains, how this depends on the substrates, and why the form of nitrogen (ammonium vs. organic) determines its value.
The first Clean Hydrogen Portfolio Standard auction in Korea: Korea Southern Power (KOSPO) was selected for 750 GWh a year from ammonia co-firing, against 6500 GWh offered; a 15-year contract from 2028.
On 18 December 2024 the European Commission approved a large aid scheme for producers of upgraded biogas and e-methane in Denmark: a 20-year premium, five tender rounds in 2024–2030, 7.9 PJ a year.
What Korea's 2019 Hydrogen Economy Roadmap envisaged: 6.2 million vehicles, 1,200 stations and 15 GW of fuel cells in the power sector — and how real life tested these targets.
On 16 December 2024 GSE opened the first call under the FER 2 decree of 19 June 2024: 10 MW for biogas and biomass, with a tariff for small biogas of 233 EUR/MWh for 20 years.
Regulation (EU) 2024/1157 will replace Regulation 1013/2006: digital procedures, new export rules for non-OECD countries and a ban on exporting plastic waste. Key dates: 2025, 2026 and 2027.
CO₂ from burning biomethane is biogenic and in EU methodologies counts as zero, but climate neutrality depends on the feedstock, methane and N₂O emissions and land-use change.
The 14th statistical report of the European Biogas Association: production of biogases in Europe in 2023 reached 22 billion m³ (about 7% of EU gas consumption), including 4.9 billion m³ of biomethane, with a capacity of 6.4 billion m³/year at the beginning of 2024.
The draft update of the National Energy and Climate Plan (KPEiK), sent for consultation in October 2024, assumes in the WAM scenario about 15.5 TWh of biomethane in 2030 and about 40.5 TWh in 2040, plus about 9.95 TWh of biogas in 2030.
According to the EPA LMOP database, in September 2024, 488 landfills fed 542 operating landfill gas energy projects; the EPA estimates that a further 444 landfills could viably start such a project.
Croatia supports electricity from biogas and biomass with a one-sided market premium awarded in HROTE auctions for 12 years. In 2022 biogas won an average of HRK 1476.66/MWh.
The Nortegas group has obtained, under InvestEU and the European Investment Bank, framework financing of up to EUR 80 million for the construction of biomethane plants in Spain, fed mainly with slurry.
