The regulation of the minister of climate of 8 November 2023 raises reference prices in RES auctions: including PLN 872/MWh for agricultural biogas below 500 kW and PLN 1025/MWh in high-efficiency cogeneration.
I/S decides whether a BMP test ends in a result or an acidified bottle. The formula, guideline recommendations, a calculation example and the consequences of too low or too high an I/S.
On 13 October 2023 the Portuguese government announced a tender for 60 MW of grid connection capacity for new biomass power plants; a single plant may apply for a maximum of 10 MW.
An LNG station consists of a cryogenic tank, pump, dispenser and safety systems; an L-CNG station additionally vaporises gas into compressed form. We describe the components, refuelling, safety and operation.
In 2018, 243 fires at dumps and landfills were recorded, in 2019 177 and in 2020 111. We explain where waste fires come from, what is released and how to reduce the risk.
The environmental impact report is the most important annex to an application for an environmental decision. We explain what Article 66 requires, who writes it and how to describe odours, noise and transport.
The regulation of 12 October 2023 sets out the detailed list of substrates that may be used in an agricultural biogas plant: manure, straw, agricultural and food industry waste, by-products. It enters into force on 18 October.
On 5 October 2023 the French regulator CRE gave its opinion on a draft amendment to the BG16 tariff: indexation is to run from the date of application, not from the start of the contract.
On 16 October 2023 the Council of the EU agreed its position on the revision of the Urban Wastewater Treatment Directive. By 2045 treatment plants are to produce as much energy as they use, with interim targets.
On 13 October 2023 the US Department of Energy named seven regional clean hydrogen hubs, which were conditionally awarded up to USD 7 billion from the infrastructure law.
On 9 October 2023 the Council of the EU formally adopted the new Renewable Energy Directive (RED III) with a binding target of 42.5% in 2030. The directive will be signed and published, and countries will implement it within about 18 months.
Growing waste volumes, infrastructure gaps, illegal landfills and new streams (batteries, photovoltaics) are the main challenges. An overview of the tools: EPR, the deposit return system and the Batteries Regulation.
The inoculum determines the reliability of a BMP test. We discuss sources, degassing, control parameters (VS, pH, alkalinity, VFA, NH₄⁺) and the effect on kinetics and result.
Waste can cease to be waste after recycling or other recovery, but only if it meets the four conditions of Article 14 and the specific conditions. We explain where to get them from and what this means for digestate and compost.
From 1 October 2023 importers of goods covered by CBAM, including fertilisers, cement and steel, must collect data on embedded emissions. The first quarterly reports are due by the end of January 2024.
For biomethane to be recognised as sustainable, it must be certified in a recognised scheme, e.g. ISCC or REDcert, with mass balance and GHG verification. We describe the path, the documents and voluntary markets.
In AR4 and AR5 of the British contracts for difference, the caps for anaerobic digestion were 128 and 136 GBP/MWh (2012 prices), but no AD or biomass CHP project received a contract.
PP and HDPE caps can be shredded and processed into filament in an extruder, but the material is hard to print with. We discuss the educational value, technical limitations and the EU context.
In September 2023 the IEA published the Global Hydrogen Review 2023. Global hydrogen demand in 2022 was about 95 Mt, and low-emission production is still very small.
On 13 September 2023 Regulation (EU) 2023/1804 on alternative fuels infrastructure (AFIR) was adopted. It replaces Directive 2014/94/EU and sets targets for chargers, hydrogen stations and LNG in seaports.
The Korea Institute of Energy Research (KIER) developed a process for removing H₂S, CO₂ and moisture from biogas from food waste and slurry; the pilot processed an average of 3 t of biogas per day.
On 12 September 2023 the European Parliament approved the text of RED III agreed with the Council in March. The binding renewables target for 2030 is 42.5%, and the directive changes the rules for biomass, transport and gas certification.
From 1 October 2023 the Green Gas Support Scheme pays 6.09 p/kWh in Tier 1, 3.90 in Tier 2 and 3.45 in Tier 3. The third band rose from 1.72 p/kWh.
In Bulgaria, electricity from biomass and biogas is supported by feed-in tariffs set by the EWRC and by premiums from the Security Fund. Support for biomass lasts 20 years.
