Training | Biomethane Grid Injection

09 February, 2023 9:00AM - 4:00PM

Venue: Online

The subject of the course is “Biogas, Biomethane and Grid Injection;  Background, Overview and Opportunity.” It covers the technicalities, process and procedures for biomethane-to-grid projects as well as the benefits to be gained.



The course will provide an understanding of opportunities and the means by which biogas manufactured from waste can be upgraded to make biomethane and to meet the various standards for entry into the existing gas supply network – this is to displace the equivalent quantity of fossil gas and hence support Net Zero initiatives.  Also, the course will explain how the value of biomethane sold into the market (and support from the Green Gas Support Scheme) generates an income stream.

Who is it for?

This is intended to be of interest to the anaerobic digestion industry. It also appeals to anyone wanting to improve environmental performance and commercial yield, who is currently, or proposing to finance, operate or develop a new or existing biogas production site, biogas-fuelled CHP site, waste processing and biogas production facility, or with a process that generates significant bio-degradable waste.


About the course leader

Iain Ward is a Chartered Engineer and has worked in the UK and overseas gas industries for more than 40 years in various technical, regulatory and safety roles. He was project manager on the first UK Biomethane to Grid project and has been closely involved in the initial and subsequent development of plant, equipment and operations of gas to grid plant. In conjunction with CNG Services he has been responsible for, or closely involved in, about 40 BtG projects to date and various feasibility and Hazop studies, including high pressure and virtual pipeline outlets, across all the UK gas networks.

The Anaerobic Digestion and Bioresources Association (ADBA) was established in 2009 to represent the UK anaerobic digestion (AD) and bioresources industry and to support the development of a safe, high-performing industry.
