Using fiber optics to advance safe and renewable energy

Fiber optic cables, it turns out, can be incredibly useful scientific sensors. Researchers have studied them for use in carbon sequestration, groundwater mapping, earthquake detection, and monitoring of Arctic permafrost thaw. Now they have been awarded new grants to develop fiber optics for two novel uses: monitoring offshore wind operations and underground natural gas storage. … read more

Water splitting advance holds promise for affordable renewable energy

A team has developed a less expensive water electrolysis system that works under alkaline conditions but still produces hydrogen at comparable rates to the currently used system that works under acidic conditions and requires precious metals. This advance brings down the cost of water splitting technology, offering a more viable way to store energy from solar and wind power in the form of hydrogen fuel. … read more

Consider marine life when implementing offshore renewable power

With countries adopting green energy practices, renewable energy now accounts for a third of the world's power. As this trend continues, more countries are looking to offshore energy sources to produce this renewable energy. Researchers identify situations where green technology such as wind turbines, wave energy converters, and other marine renewable energy devices (MREDs) have had negative consequences on marine life. … read more

Supporting structures of wind turbines contribute to wind farm blockage effect

Much about the aerodynamic effects of larger wind farms remains poorly understood. New work looks to provide more insight in how the structures necessary for wind farms affect air flow. Using a two-scale coupled momentum balance method, researchers theoretically and computationally reconstructed conditions that large wind farms might face in the future, including the dampening effect that comes with spacing turbines close to one another. … read more

Insects' drag-based flight mechanism could improve tiny flying robots

Thrips don't rely on lift in order to fly. Instead, the tiny insects rely on a drag-based flight mechanism, staying afloat in airflow velocities with a large ratio of force to wing size. Researchers have performed the first test of drag force on a thrip's wing under constant airflow in a bench-top wind tunnel and, drawing from microfabrication and nanomechanics, they created an experiment in which a thrip's wing was glued to a self-sensing microcantilever. … read more

Biodiversity and wind energy

The location and operation of wind energy plants are often in direct conflict with the legal protection of endangered species. The almost unanimous opinion of experts from local and central government authorities, environmental NGOs and expert offices is that the current mechanisms for the protection of bats in wind power projects are insufficient. … read more

Decarbonizing the power sector

Electricity supply is one of the biggest CO2 emitters globally. To keep global warming well below 2°C, several paths lead to zero emissions in the energy sector, and each has its potential environmental impacts -- such as air and water pollution, land-use or water demand. Using a first-time combination of multiple modelling systems, an international team of researchers has now quantified the actual benefits and downsides of three main roads to decarbonization. … read more

Boosting wind farmers, global winds reverse decades of slowing and pick up speed

In a boon to wind farms, average daily wind speeds are picking up across much of the globe after about 30 years of gradual slowing. Research shows that wind speeds in northern mid-latitude regions have increased by roughly 7% since 2010. … read more
