Waste innovation shows the way forward

Waste innovation shows the way forward

News that a supermarket outlet has come off the National Grid and is powering itself entirely via anaerobic digestion of its food waste should not come as too much of a surprise – the UN estimates that one third of all food is wasted, and supermarkets are increasingly acknowledging their responsibilities in tackling this sizeable [...]

Fuel cells could make off-grid mainstream

Fuel cells could make off-grid mainstream

A new generation of fuel cells might just be the future of stable and reliable energy supplies at home – at least that’s what a number of researchers and big firms think. In June Germany’s Fraunhofer Institute produced a new ceramic fuel cell (which looks a bit like a CD rack) that efficiently converts natural [...]

Turbine technologies: Winds of change

Turbine technologies: Winds of change

From offshore to on your roof, wind power could see some big changes over the coming years. Starting at the larger end of things, a new floating wind turbine could potentially cut costs-per-Megawatt by around half come the 2020s, according to a study commissioned by the Energy Technologies Institute (ETI). The continued development of large-scale [...]
