The Anaerobic Digestion & Biogas Association (ADBA) has described biomethane as a vitally important part of our energy future and is keen to urge its long-term deployment.

The encouragement came in response to a recent announcement by the UK Department for Energy & Climate Change (DECC) of consultation on tariffs for the Renewable Heat Incentive (RHI).

The DECC is proposing tiered options for the tariffs, with ADBA eager to work closely with the DECC and its own members over the course of the consultation to provide ‘the evidence they need’ to provide tariffs that promote biomethane development.

ADBA Chief Executive Charlotte Morton said, “The consultation on RHI tariffs offers the opportunity to put support for biomethane to grid on a long-term basis. Biomethane is a vitally important part of our energy future, offering the chance to decarbonise difficult areas like the gas grid and heavy goods transport without widespread changes to infrastructure.”

“Although we are pleased that DECC are proposing a tiering option for the tariffs, we are concerned that the tariff levels proposed in the consultation document will be too low to continue to incentivise deployment.”

Embryonic space

Renewable energies like biomethane – and the wider biogas spectrum – are increasingly coming to the fore as the world strives for a more diversified and sustainable energy mix, with anaerobic digestion (AD) the key to unlocking the potential of many of these natural resources.

A trend towards higher natural gas prices, coupled with the demand for renewable energy, is creating strong demand for the equipment to upgrade raw biogas to purified biomethane and a number of industrial gas related companies are already involved in this ‘embryonic’ space.

Chesterfield Biogas (CBG) and Xebec Adsorption Inc., are two companies known to be engaged in this business, both of whom can provide biogas upgrading units for the purification of biogas to biomethane streams.

The anaerobic digestion and biogas industry will discuss the issues facing ongoing development of the biomethane sector, as well as AD’s potential to deliver ultra low carbon gas and electricity, on 2nd & 3rd July at the UK AD & Biogas 2014 trade show in Birmingham (UK).
