Biogas plants in Hokkaido create a large stream of liquid digestate. What are the numbers (140 biogas plants, 800,000 cows) and what does Japanese research say about its use on arable fields?
How the Act on Renewable Energy Sources defines biomethane, who counts as a producer and which register you must enter: URE or KOWR. Deadlines, obligations and reports.
The operator Nedgia (Naturgy) has connected to the grid a biomethane plant in Cabanillas in Navarre: injection capacity of 320 Nm³/h, up to 22 GWh a year, with feedstock mainly pig slurry. It is the 12th injection point on the Nedgia (Naturgy) network in Spain.
On 26 July 2025 in the Port of Barcelona the cruise ship Mein Schiff Relax took 1,875 m³ of bioLNG from the barge Haugesund Knutsen. The fuel came from the Enagás terminal and had an ISCC EU certificate.
Digestate must be stored between the dates of transport to the fields. We compare closed, open and lagoon storage, the effect of covering on emissions and how to estimate capacity.
Gas engines do not burn all the methane; unburnt CH₄ (slip) worsens the GHG balance of bioLNG. We compare road and marine engine types and convert slip into gCO₂e/MJ.
A Blunomy report for Energy Networks Australia (31 July 2025) estimates the biomethane potential at about 400 PJ per year; the first 50 PJ could cost AUD 10–27/GJ.
The Central Electricity Regulatory Commission (CERC) set generic tariffs for 1 July 2025 – 31 March 2026: biogas 10.88 Rs/kWh, biomass 9.43–10.63 Rs/kWh, bagasse cogeneration 7.33–9.18 Rs/kWh.
Orlen and Krajowa Grupa Spożywcza (KGS) signed in July 2025 a memorandum on technology for producing biomethane from agricultural and production waste. Orlen is aiming for up to 0.24 billion m³ of biomethane a year by 2035.
H1 2025: 251 hours with a negative price, RDN PLN 427.5/MWh. The new negative-hours rule in practice and the FIP + 2× result.
The One Big Beautiful Bill Act extended the 45Z credit to the end of 2029, tightened feedstock requirements and left an exception for manure-based fuels. For 45Y/48E the sources do not settle the fate of biogas.
Poland has several municipal waste thermal treatment installations (ITPOK). We outline their number, their role in the system and the new installation in Gdańsk launched in 2025, with a caveat about differences in the data.
In the first round of Hydrogen Headstart, ARENA awarded AUD 814 million to the Murchison project (1.5 GW) and up to AUD 432 million to Orica's Hunter Valley hydrogen hub.
Why digestate emits ammonia, what the losses depend on and how to limit them: trailing hoses, soil injectors, rapid incorporation into soil, covering tanks.
On 2 July 2025 the European Commission presented a formal proposal to amend the EU climate law with a target of a 90% net emission reduction by 2040. The bioenergy industry welcomed it as an important step.
We compare whole-cycle emissions for natural gas, LNG and biomethane from different substrates. We indicate what makes up the balance, how to calculate per MWh and why the results for biomethane differ so much.
On 25 June 2025 the European Commission adopted the Clean Industrial Deal State Aid Framework (CISAF). It is meant to make it easier to create support schemes for renewable energy and decarbonisation.
The Bundesnetzagentur awarded 244 contracts for 187 MW. The weighted average price was 16.53 ct/kWh, and the biomethane tender ended with no bids.
How to plan fertilisation with digestate: calculating the rate from the analysis, the role of ammonium nitrogen, the 170 kg N/ha limit from the Nitrates Directive, and the rules on timing and good practice.
After the landfill ban, sewage sludge goes to agriculture, composting, digestion and incineration. We analyse the routes, restrictions, phosphorus recovery and the impact of the new municipal wastewater directive.
A biomethane plant carries technical, feedstock, market, regulatory, grid and financial risks. We present a risk matrix with an assessment of probability and impact, and mitigation measures and contractual provisions.
India's Ministry of Petroleum and Natural Gas raised the procurement price of compressed biogas (CBG) from 1380 to 1478 Rs per MMBtu from 1 June 2025, linking it to 85 per cent of the average CNG price.
On 21 May 2025 the transposition deadline for most provisions of the RED III Directive passed. For biomass fuels the sustainability criteria now cover installations from 7.5 MW (biogas from 2 MW).
On 21 May 2025 the transposition deadline for the RED III Directive expired. Most Member States did not meet it.
