## Summary

The Environment Agency has awarded a contract titled "RDE610 Methane Slip - Exhaust Gas Treatment Options" to Ricardo-AEA Ltd for research and development consultancy services. This procurement falls under the services category and spans from 8th August 2024 to 31st December 2024, with a total value of £50,000.93. The process was initiated as a selective tender through a call-off from a framework agreement, primarily aimed at addressing methane slip in lean-burn gas engines. This project is relevant to various locations, including the United Kingdom, British Overseas Territories, Channel Islands, Isle of Man, Europe, and the Rest of the World. The process started with a tender period ending on 1st August 2024.

This tender presents a valuable growth opportunity for businesses engaged in environmental consultancy, research, and technology development targeting gas emissions control. Small and medium enterprises (SMEs) and voluntary, community, and social enterprises (VCSEs) are particularly well-suited to compete for such projects given their innovative approaches and specialised expertise. By participating in such tenders, businesses can expand their portfolios, demonstrate their capabilities in emerging technologies, and contribute to environmental sustainability efforts championed by a reputable entity like the Environment Agency.

## Notice

Methane slip is the term used to describe the portion of methane (fuel) that passes through a gas engine without being combusted and is emitted to atmosphere via the engine exhaust. It may also describe methane that is not captured during biogas upgrading and is emitted with the off-gas via the process vent stack. This project is primarily concerned with methane slip from (stationary, reciprocating) lean-burn gas engines used to generate electricity or for cogeneration (CHP). Lean-burn gas engines are commonly deployed at landfill sites, wastewater treatment facilities and anaerobic digestion plants to generate electricity from the methane rich biogas produced by those sites. The gas engines are typically in the 500kWe to 2MWe range. Lean-burn engines are generally favoured over other types due to their higher fuel efficiency and lower NOx emissions. However, the combustion conditions that favour lower NOx formation typically result in higher methane slip rates as an inherent part of the engine operation. Historically, the options to treat exhaust gases to remove unburned methane have been limited. The low exhaust temperatures associated with lean-burn engines hindered the operation of the 2 or 3-way catalyst systems often used for emissions reduction. However, the Environment Agency is aware that considerable research has been taking place on methane slip reduction and that viable exhaust treatment techniques may now or may soon be commercially available. The Environment Agency proposes to let a project to review current and emerging techniques for the abatement of methane in lean-burn engine exhausts.
