Dr Greg Brittles, Tokamak Energy TOKAMAK ENERGY Dr Greg Brittles’ eyes gleam with excitement when he explains the project he is working on. “It’s every engineer’s dream really, to have a project that’s technically challenging, which requires you to develop new technology and solutions to hard problems, but that are […]

Farm of Vertical Axis Wind Turbines.

New research from Oxford Brookes University has found that the vertical turbine design is far more […]

Illustration Credit: Cortland Johnson | PNNL Small stockpiles of biomass such as sewage, food waste, and wood chips are often overlooked in visions of future sustainable fuel and chemical production. The dismissal arises because transporting these materials to a large-scale, centralized bio-refinery would require more energy than they produce. Yet […]

ANIMATION Berkeley Lab co-led collaboration with DESY and TU Freiberg brings us a step closer to more efficient photovoltaics and solar fuel systems. In the past 50 years, scientists have made great advances in photovoltaic technologies that convert sunlight into electricity, and artificial photosynthesis devices that convert sunlight and water into carbon-free […]

Wind energy scientists at Cornell University have released a new global wind atlas – a digital compendium filled with documented extreme wind speeds for all parts of the world –  to help engineers select the turbines in any given region and accelerate the development of sustainable energy. This wind atlas […]

Researchers leverage renewable electricity for widespread, distributed hydrogen fuel production. Northwestern University researchers have developed a highly effective, environmentally friendly method for converting ammonia into hydrogen. Outlined in a recent publication in the journal Joule, the new technique is a major step forward for enabling a zero-pollution, hydrogen-fueled economy. The idea of using ammonia […]
