Biomethane cultivates its positive externalities
The French biomethane sector is convinced about the positive externalities of biomethane. It therefore promotes the many direct and indirect benefits as well as the economic, agronomic and ecological advantages over the fossil fuels. And the list is long: fight against water pollution, reduction of greenhouse gas emissions, organic fertilizer inputs, soil cover, changes in agricultural practices, etc. Enea Consulting reviewed in a scientific work the externalities associated with biomethane production and concluded that the additional benefits of biomethane - in addition to the energy produced - would amount to 55 to 75 Euros per MWh by 2030. Next to Enea, INRA is studying the LCA of agricultural biomethane on behalf of GRDF. First results are already convincing.

Regulations and subsidies of biomethane in France
During a meeting of the biomethane working group of Club Biogaz ATEE, Marie Verney, lawyer at the association, gave an overview on the rather complicated legislation of biomethane injection and compensation in France during a workshop organized by AMORCE comparing the situation in 2018 with 2019. The presentation is in French only.
Biogas18 - Greening the gas
The Austrian Biogas18 congress, which took place this year in Linz, was all about biomethane. Biomethane plays a special role in the future Austrian energy system due to its cross-sectoral applications. This has also been recognized by the government and given high priority in “#mission2030 Biogas”. The consensus is that there is still considerable potential for expansion, but that there are also many possible applications. Energy storage in the form of biogenic waste from industry and residues from agriculture on the raw materials side and biomethane in the gas network on the logistics side were also highlighted as a special capability.

Gas upgrading with ionic solutions consumes less energy
There are at least four basic methods to upgrade biogas to biomethane. They all use energy either in form of heat and or electricity. Gas scrubbing is currently the most widely used process for processing raw biogas. A research team from the Engler-Bunte-Institut in Karlsruhe, Ionic Liquids Technologies GmbH from Heilbronn and Powerfarm Bioenergie GmbH from Tuningen has now successfully demonstrated the use of ionic liquids as washing media in a biogas plant. In the newly developed a new washing process, where the absorption of CO2 takes place at almost the same temperature (60-80°C) as the subsequent recovery (regeneration) of the washing liquid. The regeneration process no longer requires external heat. This saves energy and lowers costs compared to conventional gas treatment concepts.
Biomethane from P2G in demonstration scale
27 project partners from six European countries are further developing the P2G technology in the Horizon 2020 project STORE&GO. Three different technologies are tested in Germany (Falkenhagen, Brandenburg) with an alkaline electrolyser and an isothermal catalytic P2G technology (1 MWel), in Italy (Troia, Apulia) with a PEM electrolyser and a modular milli-structured catalytic P2G technology (200kWel) and Switzerland (Solothurn) with a PEM electrolyser and a microbial methanisation (700kWel peak power). The latter is a fully integrated plant with connection to a water, heat, gas and electricity grid. Hydrogen is produced from solar energy and directly fed into the gas grid or used in P2G with CO2 from industry or ambient air.
The RNG Coalition promotes state and provincial policies for RNG in California
California is one of the USA States with the most ambitious decarbonisation goals by reducing CO2 emissions completely by 2045. For this reason, there are numerous federal, state and provincial policies that incentivise the production of renewable natural gas (RNG), many of which have come about as a result of the work of associations such as the RNG Coalition which promotes the development, use and diffusion of RNG throughout North America.
Efficient fine tuning of Power2Gas with trickling filters
The Pirmasens research institute (PFI) having a long experience in biological methanation and Power2Gas technology (P2G), implemented a demonstration plant in the Pirmasens Energy Park. Using the trickle current reactors developed by PFI, the CO2 content of the biogas from PFI's own biogas plant together with hydrogen is converted into feedable natural gas with up to 99 percent methane content and fed into the natural gas network since the end of 2016. The initial focus here was on further increasing productivity in biological methanation through a newly developed growth medium for the production strains. Recently, the PFI researchers were able to show that the redox potential of the medium has a significant effect on the conversion rates of the bacteria. These findings were incorporated into the development of new media variants to increase cell density and productivity. (in German only)
Gas vehicles – a technology overview
Natural gas/biogas vehicles are generally considered as an alternative to "internal combustion engine drives" although their potential for reducing CO2 emissions and integrating renewable energy is still underestimated. Apart from the use of biomethane from biogas there is a large potential of synthetic biomethane, which can be generated from temporarily surplus renewable power. The critical review of EMPA in the context of Swiss legislation is of general interest. The study shows that 1) Already today liquid biogas is a suitable alternative to petrol and diesel vehicles for everyday use even with low ranges of 350 to 500 km per day. As compared to petrol or diesel they have a far lower environmental impact. 2) When operating with renewable gases, the vehicles have the lowest CO2 emissions of all renewable vehicle concepts even when compared to e-mobility. 3) Gas vehicles still have a higher purchase price of around 15% when compared to gasoline vehicles, but doubling of the current number of gas vehicles would allow economic operation when the whole value chain is considered. 4) Gas vehicles are as safe as petrol vehicles.

SEAT participates in a new European biomethane project
SEAT will participate until 2023 in the Life Landfill Biofuel project, recently approved by the European Commission, which aims to obtain renewable gas from municipal landfills. The objective is to achieve more efficient management by obtaining biomethane from an indigenous and abundant energy source. The project will be developed together with other collaborating entities (FCC, IVECO, the University of Granada, the CARTIF Foundation, SYSADVANCE and Gasnam) over the next four years and has a global budget of 4.6 million euros, of which the European Commission finances 55%. SEAT is already participating in the Life Methamorphosis project to obtain biomethane from previously selected waste and slurry from a farm in Lleida. The new Life Landfill Biofuel project is another step since the raw material comes directly from the landfill, without prior separation.
First LNG freight locomotive in the Baltics
Operail, an international logistics and transportation company, has entered into a cooperation agreement with the Latvian company DiGas to develop the first cargo-carrying liquefied natural gas (LNG) freight locomotive in the region. Adding the LNG system to freight locomotives is a landmark event in Baltic railway transportation and the railway sector in general. On average, an LNG locomotive uses 30% less fuel and emits 20% less carbon dioxide and 70% less sulphur dioxide. The reconstruction process of the American General Electric C36 locomotive involves dividing the 17,000-litre fuel tank in two – half for diesel fuel and half for LNG – and the addition of new systems. The information systems of an LNG locomotive store all information regarding fuel consumption and data analysis will allow further savings. The first LNG locomotive should be completed next spring and tested in summer 2020.
Record efficiency for a person car gas engine
In addition to electric and hydrogen powertrains, gas engines also play an important role in the Swiss Competence Centre for Energy Research in the Field of Mobility ("SCCER Mobility") headed by ETH Zurich. This is because vehicles powered by pre-processed biogas or synthetic methane ("e-gas"). As part of the Horizon 2020 “GasOn” project Volkswagen has developed a brand new 2 litre gas engine with a highly efficient combustion process. The behavior of the ignition was optimized in a pre-chamber and an overflow of the hot rays into the main combustion chamber. Compared to the state of the art, the consumption of the new gas engine with pre-chamber combustion process was reduced by 20% (converted into WLTP standard consumption for a mid-size passenger car). The peak efficiency in the best engine configuration was over 45%, with efficiencies of over 40% achieved over a wide operating range. Such values are currently only achieved by significantly larger engines, such as those used in commercial vehicles, stationary or marine applications. In comparison, petrol engines typically have efficiencies of 35 to 40%. The GasOn project has developed a series of other outstanding improvement which are all compiled on the project’s website.
Hurtigruten cooperates with Biokraft and in future runs on biogas from fish waste
The Norwegian shipping company Hurtigruten signs a multi-year contract with the Norwegian company Biokraft for the supply of climate-neutral liquid biogas (LBG). From 2020, the traditional post ships will set sail with the environmentally friendly fuel from dead fish and other organic waste. With a term of seven and a half years, the contract between Hurtigruten and Biokraft is the most comprehensive agreement to date on the supply of liquid biogas (LBG) to a shipping company. The partnership includes the almost daily delivery of biogas from organic waste to Hurtigruten. The Hurtigruten ships are thus the first in the world to operate with fossil-free LBG. With the partnership between Hurtigruten and Biokraft, the world's largest provider of expedition sea voyages and the world's largest producer of biogas combine forces and expertise. The first biogas delivery from Biokraft to Hurtigruten is expected in 2020.

Best greenhouse gas balance through biomethane cars
A study by the German and Swiss automobile clubs ADAC and TCS respectively, has examined the most common types of fuel currently available with regard to greenhouse gas emissions on the basis of a VW Golf. The study concludes that electric cars perform best when 100% green electricity is used. If, however, the current (German) electricity mix is used, natural gas passenger cars show the best greenhouse gas balance. The balance of natural gas passenger cars is significantly improved by the use of 15% biomethane. Also, the Plug-in hybrid as combination of a gasoline and an electric motor achieves no substantial improvement with application of the current mix Germany even when compared to the conventional gasoline engine. Its problem is the additional battery, which has a negative effect on the climate balance. Only with 100% regenerative energy electric car show the best greenhouse gas balance, closely followed by the fuel cell vehicle. The balance of the plug-in hybrid vehicle also improves when regenerative electricity is used. The natural gas car can also benefit massively from 100% regeneratively produced biomethane.

Pressemeddelelse fra energistyrelsen:
Energiforligskredsen har den 4. april 2019 besluttet at justere kriterierne for planlagte biogasprojekter, der nettilsluttes efter 1. januar 2020.
Med energiaftalen fra sommeren 2018 besluttede samtlige Folketingets partier at stoppe den nuværende støtteordning til nye biogasanlæg i 2020 og at indføre et loft over støtten til produktionen.
Energiforligskredsen besluttede den 8. februar 2019, at stopdatoen bliver den 1. januar 2020, og aftalte samtidig en række kriterier for de planlagte anlæg, som ikke kan nå være etablerede inden da.
Energiforligskredsen har den 4. april besluttet at justere visse af dispensationskriterierne for de planlagte projekter. Det er besluttet, at fristen for, hvornår der senest skal foreligge VVM-tilladelse og miljøgodkendelse udskydes fra den 8. februar 2019 til den 1. juli 2019.
Det er fortsat et kriterie, at der er foretaget dokumenterbare irreversible investeringer senest den 8. februar 2019.
Det er endvidere besluttet, at der kan gives dispensation til de opgraderingsanlæg, som inden den 1. april 2019 har indgået en tilslutningsaftale med gasdistributionsselskabet om nettilslutning før den 1. januar 2020, men hvor tilslutningen forsinkes af uforudsete hændelser.
De nu gældende kriterier, som skal opfyldes for at opnå støtte til anvendelse af biogas på de eksisterende biogasstøtteordninger, fremgår af Energistyrelsens notat af 5. april 2019 og erstatter udmeldingen af 8. februar 2019. Læs mere på energistyrelsens hjemmeside
