Cwmniau Cleantech clodfawr

Two of the top ten hottest clean technology companies in Europe are based in Wales. According to Cleantech 100, produced by The Guardian and Library House, Deep Stream Technologies in Bangor and Atraverda of Abertillery are worthy of a place in the higher echelons.

Deep Stream Technologies are reshaping electronic circuits to monitor, measure and manage energy at the point of use. Sensors within the circuits help to control the use of power.

Atraverda work with conductive ceramic that stores power better than conventional lead-acid methods. This allows for smaller, lighter, more powerful and longer-lasting batteries. The bipolar batteries developed by Atraverda can be 40% smaller, 30% lighter, and use approximately 50% less lead than normal batteries.

Other Welsh companies to make the list are Inetec, Bridgend, generating energy from food waste, Pelikon, Caerphilly, developing next generation liquid crystal displays, and G24i, Cardiff, creating new solar cells that operate in low-light conditions.
