  • Sustainable improvement of drinking water quality by nanofiltration powered by renewable energy

    Desalination membrane technology is increasingly used for water production. However, the main disadvantage of desalination is related to energy consumption and CO2 emissions, so desalination powered by renewable energy (RE) is getting interest. In this study nanofiltration (NF) membranes have been used for drinking water quality improvement in a pilot plant (50 m3/day) powered by RE ...

  • The Smart Grid ‘Acid Test’ – Accommodating Variable Renewable Energy (VRE)

    In the previous posts, we have discussed the need for the regulators and policy makers to develop a new framework on which to build Smart Grid. The next stage is to investigate how much VRE can be accommodated through Smart Grid. Maximising the amount of VRE that can be accommodated is the ‘Acid Test’ for Smart Grid. We are moving from a central system that provides consistent power ...

  • Concentrating Solar Power Global Outlook 09 - Why renewable energy is hot

    What is CSP? CSP (Concentrating Solar Power) systems produce heat or electricity using hundreds of mirrors to concentrate the sun’s rays to a temperature typically between 400 and 1000ºC. There are a variety of mirror shapes, sun-tracking methods and ways to provide useful energy, but they all work under the same principle. Individual CSP plants are now typically between 50 and 280MW in size, ...
