Day-ahead market PLN 283.2/MWh versus FIT PLN 617.5/MWh: in H1 2021 the fixed price remains more than twice as high. Indexation and the cogeneration bonus.
Beca, Firstgas and Fonterra report: biogas could cover about 20% of New Zealand's gas use by 2050
A Beca report prepared with Firstgas and Fonterra indicates that renewable gas could replace nearly 20% of national gas use by 2050 and avoid about 4% of energy emissions.
Orlen Południe and PGNiG file an application with UOKiK for a biomethane company; Jeżewo in the plans
Orlen Południe and the Polish Oil and Gas Company (PGNiG) notified the Office of Competition and Consumer Protection (UOKiK) of their intention to create a 51/49 special purpose company. Among the planned projects is the expansion of the 1.8 MWe biogas plant in Jeżewo to 3.2 MWe and about 8 million m³ of biomethane.
From 3 July 2021, bans on single-use plastic products (the SUP Directive)
From 3 July 2021, EU Member States are to apply bans on placing on the market, among others, single-use plastic cutlery, plates and straws and expanded polystyrene containers. Directive 2019/904 also covers biodegradable plastics.
GHG balance of biomethane under RED II step by step: formula, components and reduction thresholds
How the GHG emissions of biomethane are calculated in the RED II directive: the formula E = eec + el + ep + etd + eu − esca − eccs − eccr, the components, the fossil fuel comparator of 94 g CO₂e/MJ and the required reduction thresholds.
