Clean Technology is one of the fastest growing industries on the planet. It covers technologies such as clean energy generation, environmentally friendly construction, green transportation, emissions reduction and energy saving devices. Headed by Andrew Thompson, the group has a wealth of expertise across these technologies and we are ready to meet the demands of this important sector.

Our experience

Members of the Group have specific experience in energy generation technologies such as photovoltaic cells, wind turbines, energy harvesting from boilers and gas outlets, fuel cells, biomass and piezoelectric power harvesting systems.

The Group also has experience in transportation technologies such as efficient air brake systems, hybrid vehicles, kinetic energy recovery systems (KERS) for automotive applications, engine emissions and fuel pump control systems. On the life sciences side, we have experience in clean refrigerants, wastewater treatment, bio fuels, waste composting safety devices and nanoparticulate formulation design.

Our expertise

We advise a range of Cleantech industry clients - from individual inventors and UK based start-ups to multinationals. We offer a full range of services to companies in this sector.

Wider perspectives

We endeavour to keep a close eye on important developments in this diverse and rapidly evolving sector of the economy and get involved where possible in key events and forums such as the All-Energy exhibition and conference on renewable energy; Sustainability Live, a similar event focusing on energy, water, land and sustainability; and the Rushlight Cleantech awards.

Recently, we sponsored the national Rushlight Cleantech survey, an independent report on the development of clean technologies in the UK, utilising direct feedback from Cleantech organisations to influence future Government thinking and support. Such initiatives help ensure we are well placed to advise our clients on key developments in the market place.
