Renewable Energy

The US federal government has given the green light to the country's largest offshore wind farm to date, and one that will greatly expand its capacity to generate this form of renewable energy by adding 800-MW to the mix.

Perovskite solar cells can suffer from stability issues and quickly deteriorate during use, but scientists at Brown University have come up with a way of addressing this by targeting a weak point with something they call molecular glue.

California is set to be home to two new compressed-air energy storage facilities – each claiming the crown for world’s largest non-hydro energy storage system. Developed by Hydrostor, the facilities will have an output of 500 MW and capacity of 4 GWh.

Scotland's Orbital Marine Power has completed the build on what it claims will be the world's most powerful operational tidal turbine. It's now on its way to the Orkney Islands, where it'll have a chance to prove its worth connected to the grid.

One thing holding back perovskite solar cells is an intrinsic instability and a vulnerability to the elements. Scientists believe they may have found a solution to this hiding in hair swept up from the floor of a local barbershop.

A team from Cornell University has put forward a compelling example of what cheap, environmentally friendly energy storage can look like, fashioning a 3D electrode out of low-cost aluminum for a battery with a very long cycle life.

There are energy sources all over the place, if you know where to look. Researchers at CUHK have now designed new modular nanogenerators that can harvest energy from various different types of motion, such as ocean waves or a person's body movements.

An ambitious new project could provide Helsinki with a sustainable source of heat and double as an attractive place for Fins to escape winter. Hot Heart envisions a series of manmade islands that store thermal energy and offer places for recreation.

A new project in the Australian Outback will trial an innovative technique for converting solar energy into hydrogen by capturing moisture from the air and splitting it via hydrolysis, making it possible for hot, arid areas to become energy exporters.

Now is the time, says a new report commissioned by the US Dept of Energy, for "urgent" government and private sector investment in a pilot fusion power plant on US soil by 2040. The report also lays out the key technical challenges that need solving.

BP and Chevron have led a US$40 million investment round for a Canadian startup that claims to have developed a unique way to extract energy from geothermal heat on demand, using an unpowered looping fluid design that's already prototyped in Alberta.

Denmark's Vestas is looking to become an industry leader in offshore wind, and has introduced the V236-15.0 MW turbine to take the fight to GE. The new design's blades offer the largest swept area in the world.
