By 2050, photovoltaic technologies that convert sunlight into electricity could enable many single- and multi-family buildings in Switzerland to produce enough energy to meet their own consumption needs, including the charging of electric vehicles. Ursin Gstöhl and Stefan Pfenninger of ETH Zürich report these findings in the open-access journal PLOS ONE on March 4, 2020.

From cell phones, to solar power, to electric cars, humanity is increasingly dependent on batteries. As demand for safe, efficient, and powerful energy storage continues to rise, so too does the call for promising alternatives to rechargeable lithium-ion batteries, which have been the dominant technology in this space.

A technique based on the principles of MRI has allowed researchers to observe not only how next-generation batteries for large-scale energy storage work, but also how they fail, which will assist in the development of strategies to extend battery lifetimes in support of the transition to a zero-carbon future.

Photovoltaic elements are usually found on rooftops—after all, that’s where solar irradiation is highest. However, as researchers at the Fraunhofer Center for Silicon Photovoltaics CSP have discovered, PV elements on facades can be a useful way to supplement the power supply. If appropriately designed, they can be attractively integrated and deliver 50 percent more energy than existing types of wall-mounted PV elements. Even concrete walls are suitable.

In 2003, when the Institute of Electrical and Electronics Engineers (IEEE) first drafted standards around distributed energy resources (DERs) connecting with the grid, solar power capacity was less than 1% of its current capacity. The standards document, IEEE 1547-2003, could not anticipate the technical challenges that solar and other DERs would present more than a decade later as a growing share of generation. These challenges were addressed in 2018 through a comprehensive revision of the standard.

Solid oxide fuel cells, or SOFCs, are devices that produce both electricity and heat by oxidizing a fuel such as natural gas or biogas. This energy-efficient, zero-emission technology has the potential to meet domestic and commercial power, heating and hot water needs.
