An ultrasonic acoustic fish deterrent designed for EDF’s Hinkley Point C cooling water intakes has proved “highly effective” in Swansea University trials, significantly reducing fish approach rates to the intake zone. The system uses targeted sound frequencies to steer multiple species away from the intake channel, aiming to meet Environment Agency requirements on impingement and entrainment without major changes to the intake structure. Trial results may remove the need for a large compensatory saltmarsh scheme on the Severn Estuary, easing local planning and coastal engineering constraints.

Britain is being urged to treat deep and shallow geothermal as a mainstream heat source, with a new national roadmap arguing that the country’s substantial but underused subsurface resource could displace a significant share of gas‑fired heating. The plan points to proven concepts such as mine‑water geothermal in former coalfields and district heating from deep sedimentary aquifers, which can be integrated with existing heat networks and large heat pumps. For civil and geotechnical engineers, this signals growing demand for high‑temperature boreholes, well integrity design and long‑term monitoring of thermal–hydraulic behaviour in urban ground.

Biodiversity net gain requirements on Nationally Significant Infrastructure Projects are being framed as a source of “desperately needed” long-term climate resilience, with large linear schemes such as new highways, rail corridors and strategic energy infrastructure able to create continuous habitat networks at scale. Experts point to legally secured 30‑year management plans, species-rich grassland and woodland planting, and restored wetlands as measures that can buffer flood risk, reduce heat stress and stabilise soils around major assets. For designers and contractors, this shifts BNG from a planning obligation to a core part of geotechnical and drainage resilience strategy.
