Biomethane Production: Sweden Leads with Schmack Carbotech Plant – Plus One in France

Image used as feature image illustrating how Sweden's Lead in biomethane production continues With Major New Schmack Carbotech Plant article.

This is our updated article about: Schmack Carbotech – “Sweden’s leading role in bioenergy through biomethane production, with the world’s largest installed biogas upgrading capacity, is set to further pull-ahead”.  The first article, which is still reproduced below, was published in August 2014.

A lot has changed since then, and biomethane production has risen greatly. Schmack has built a biomethane plant in France as well now.

So, we thought that we would add more general information on biomethane production to start, which we have done below.

We hope this will better explain why Sweden was right to go for biomethane back in 2014.

Biomethane Production Basics

Biomethane can be produced either by anaerobic digestion or by gasification of organic matter. Organic matter fed into the biomethane plant is transformed by anaerobic process into biomethane i.e. a compound of methane (CH4) and carbon dioxide.

As of 2016, Biomethane production from biogas was a single largest source, globally. Biogas is upgraded by various gas treatment processes to produce biomethane.

During this upgrading process, contaminants are either absorbed or scrubbed from the gas to obtain more methane per unit volume of the residual gas.

Gasification converts organic matter into syngas, which is then processed to produce methane. Methane as a whole is about 20 times more potent GHG (Greenhouse Gas) than CO2 if released in atmosphere.

When used in power generation, it generates heat and emits carbon dioxide and some other gases.

Despite all this shortcomings, biomethane produced from organic matter eliminates the release of a great deal of methane and other harmful gases into the atmosphere. The production of biomethane eliminates exposure of decaying organic matter to the air. This avoids methane and other harmful gases from fleeing into the atmosphere. via Transparency Market Research

Biomethane is a naturally occurring gas produced by anaerobic digestion of organic matter like plant & animal wastes, manure, sewage sludge, and other organic matter. Thus it has emerged out as a renewable source of energy produced worldwide.

Biomethane or Renewable natural gas (RNG) is a pipeline quality gas which is interchangeable with conventional gas. It can be used as a 100% substitute for, or blended with conventional gas streams for use in automobiles.

The developed nations of the world are diversifying their energy demand with more renewable sources. The Climate Change Conference held in Paris is one of the major reason for the nations to include more of renewable sources and cleaner fuel options in their energy mix.

Though the global biomethane market has not reached its highest peak, it does promise to show a steady rise in its growth. via Market Size By 2025

The key factor driving the growth of global biomethane market is the negative impact of conventional fuels on the environment such as harmful carbon emissions and global warming.

Such negative impacts and the continuous depletion of fossil reserves has led to the increase in usage of biomethane as an energy source. As per a research was done by California Energy Commission, biomethane can reduce GHG emissions by up to 87% compared to conventional petroleum-based fuels.

The adoption of biomethane as an alternative fuel, along with the above-mentioned factors is driving the global biomethane market. Whereas, the requirement to meet the gas quality standards in international trade, low power output for industries, and high investment costs act as the major hurdles in the growth of the market.

However, surging environmental concerns along with increasing government initiatives are expected to create huge opportunities for the growth of market in the coming years. via Biomethane Market Size, Share, Growth & Forecast By 2025

Schmack Biogas to build second biomethane production plant in France

Follow-on project opens up new market opportunities

Schwandorf, March 6th, 2017. Schmack Biogas, a Viessmann Group company, has been awarded a further contract for the construction of a biomethane production plant in Sourdun in northern France.

In mid-December, the French government adopted a new feed-in tariff for electricity from biogas. France is the biggest country in the EU and uses a much larger area for agriculture than Germany. The potential for biogas plants is enormous. With this new regulation, and in particular the subsidy, which is being extended by up to five years, it is highly likely that market growth will be stronger in future.

The planned biogas plant is expected to be able to produce 250 Nm³/h of raw biogas in the first phase of the development. However, the design already includes a possible second development phase to increase production to 500 Nm3/h of raw biogas. The raw biogas will be refined to a methane content of at least 97 percent by means of pressure swing adsorption (PSA process). As a result, the biogas will be of natural gas quality and will be able to be fed into Sourdun’s local supply network.

Schmack Carbotech, the Viessmann Group’s biogas upgrading specialist, will supply the gas upgrading plant. Schmack Biogas will supply the biogas plant and is responsible for the entire project in its role as the general contractor. via Second biomethane plant in France

Biomethane Production Basics

As of 2016, biomethane production from biogas was a single largest source, globally.

Biogas is upgraded by various gas treatment processes to produce biomethane.

Biomethane can be produced either by anaerobic digestion or by gasification of organic matter.

Biomethane from Anaerobic Digestion/ Biogas

Organic matter fed into the biogas plant is transformed by the anaerobic process into biogas (i.e. a compound of methane (CH4) and carbon dioxide).

During this upgrading process, contaminants are either absorbed or scrubbed from the gas to obtain more methane per unit volume of the residual gas.

Biomethane from Syngas

Gasification converts organic matter into syngas, which is then processed to produce methane.

Greenhouse Gas Potency

Methane as a whole is about 20 times more potent GHG (Greenhouse Gas) than CO2 if released into the atmosphere.

When used in power generation, it generates heat and emits carbon dioxide and some other gases.

Despite all this shortcomings, biomethane produced from organic matter eliminates the release of a great deal of methane and other harmful gases into the atmosphere.

Sweden’s Lead in Biomethane Production Continues With Major New Schmack Carbotech Plant

Schmack Carbotech Stockholm: Sweden’s leading role in bioenergy through biomethane production, with the world’s largest installed biogas upgrading capacity, is set to further pull-ahead. It is going beyond the level of all of other nations with the announcement that Schmack Carbotech has been signed-up as the design and build contractor for a 2000 Nm³/h biogas processing facility. The facility will be located to the south of Stockholm.

Schmack Carbotech is using their innovative Pressure Swing Adsorption (PSA) technology in their biomethane production. It will be used in a development that will enable the Swedish capital to produce pure methane (biomethane) from more biogas.

This will increase the proportion of biomethane it uses by 50%. This will provide biofuel for vehicles currently powered by natural gas.  The biomethane production will be of a high purity gas leaving the PSA with a methane content in excess of 97 per cent.

“This important new biomethane production contract at Sofielund brings to bear all of our 30 years ‘experience in the development, engineering and manufacturing of turnkey gas upgrading plants.

“As industry pioneers and market leaders in biogas purification, we are very keen to play our part in delivering a low energy yet high yield technology. A technology that in this case fits in perfectly with the Swedish government’s long-term thinking. Their aim is to become the world’s first completely oil-free economy”.

Setting new standards in biogas process efficiency, Sofielund’s new plant will be equipped with:

  • a CNG station,
  • a Carbotech PSA plant,
  • off-gas cleaning with
  • high heat recovery system combined with
  • a peak load boiler.

The biomethane production plant will also benefit from ultra-reliable VOC and Hydrogen Sulphide removal. This will make Carbotech’s robust technology ideal to produce biomethane from biogas, sewage gas and landfill gas for:

  • grid injection and
  • CNG vehicle fuel.

    These are actually ideas to follow up on regarding biogas. You have made a good point here. But, is Schmack part of Viessmann now? Therefore, is it actually Swedish, or German. If this is German technology the lead is German not Swedish, I say. Any way keep up writing.
