A snapshot of the results
- A fully electric compressor powered by battery storage replaced diesel equipment, eliminating on-site emissions and reducing noise.
- The system delivered consistent airflow, ensuring reliable bubble curtain operation that controlled sediment spread and protected the River Severn ecosystem.
- The modular rental setup enabled quick deployment, smooth operation and generated valuable R&D insights for future flood defence and inland waterway projects.
When Frog Environmental partnered with the Environment Agency on a flood risk management project in Bewdley, protecting the River Severn ecosystem was a top priority. The project involved 350 metres of new flood defences, combining demountable barriers and permanent raised walls to safeguard the local community while preserving scenic river views.
A critical element of the works was the use of bubble curtains, a system that relies on a continuous stream of rising bubbles from the riverbed to reduce sediment spread, turbidity and underwater disturbance during construction.
While effective, traditional diesel-powered compressors used to supply air for bubble curtains presented challenges. They were noisy, caused emissions and relied on fossil fuels, impacting with the project’s sustainability goals.
Frog Environmental needed a solution that was not only reliable and high-performing but also aligned with modern environmental standards. The answer came through innovative air compressor hire, combining electric compressors with battery energy storage to create a fully sustainable temporary system.
A collaborative approach for cleaner air compressor rental
Frog Environmental collaborated closely with GenAir and TCP Group to design a turnkey rental solution.
By utilising a GenAir electric compressor powered by a TCP Group battery storage system, the project achieved a zero-emission setup that minimised noise and environmental impact.
This approach offered several advantages:
- Consistency: The electric compressor provided stable airflow essential for effective bubble curtain operation
- Sustainability: The fully electric system eliminated diesel use and reduced emissions, meeting strict environmental targets
- Flexibility: The modular rental setup allowed rapid deployment and adjustments to suit site conditions
- Technical support: On-site assistance ensured smooth operation throughout the construction phase
For waterway projects, particularly in sensitive ecosystems, air compressor hire for water utilities companies is becoming an increasingly popular solution.
It provides the necessary power for mitigation measures like bubble curtains without compromising environmental standards.
Similarly, air compressor hire for renewables companies allows these projects to maintain operational efficiency while reducing their carbon footprint.

Results: high performance with minimal impact
The innovative rental solution delivered on all fronts:
- Reliable bubble curtain operation: Continuous and uniform airflow kept sediment and turbidity under control
- Environmental protection: No diesel fuel used and zero on-site emissions
- Operational efficiency: Deployment and maintenance were straightforward, thanks to the modular design and technical support
- R&D insights: The project provided valuable data to inform future inland waterway and flood defence projects
Leela O’Dea, Technical Director at Frog Environmental, highlighted the project’s success:
“This project was a great example of how collaboration and innovation can deliver real environmental benefits. The GenAir electric compressor, powered by TCP Group’s battery system, delivered exactly that.
The level of support, communication, and technical expertise throughout the trial gave us real confidence, and the results speak for themselves.”
Why air compressor hire makes sense for water utilities and renewables projects
Projects in the water utilities and renewable sectors increasingly require solutions that balance performance, sustainability and compliance with environmental regulations.
Air compressor rental offers several advantages in this context:
- Reduces carbon emissions compared to diesel-powered alternatives
- Minimises noise and disruption in sensitive environments
- Provides flexibility and scalability for temporary project needs
- Offers access to specialist technical support without long-term investment
For companies looking to implement environmental protection measures like bubble curtains, air compressor hire for water utilities companies or air compressor hire for renewables companies is not just practical, it’s a strategic choice that supports sustainability goals, reduces operational risk and ensures compliance with modern environmental standards.
Conclusion
The Bewdley River Severn project demonstrates how high-performance environmental protection can be achieved through innovation and collaboration.
By choosing a fully electric, modular rental solution for bubble curtains, Frog Environmental successfully reduced environmental impact while maintaining operational efficiency.
Whether for flood defence, waterway maintenance, or renewable energy projects, air compressor hire provides a reliable, flexible and sustainable option. It’s a clear example of how cleaner technology can deliver both operational and environmental benefits, reinforcing the importance of collaboration between water utilities, renewables companies and specialist rental providers.
