Technology and R&D

Producing nutrient-rich microbes with solar PV has the potential to produce more food with fewer resources, according to a German research group that modeled the large-scale production of microbial biomass by combining ground-mounted photovoltaics, air, water, and nutrients.

Two solar water pumps installed by the Philippines’ National Irrigation Administration (NIA) will cover a total area of more than 500 hectares.

Researchers at The Australian National University working on the photovoltaic potential of ultra-thin 2D materials have made an interesting discovery, the ability of these diaphanous materials to generate solar energy can be controlled by a mere “twist”.

Italian scientists have assessed the technical potential of vapor compression heat pumps assisted by photovoltaic-thermal systems. They analyzed two main configurations of this combination describing the advantages and disadvantages of both solutions. The cheapest and easiest to deploy system is a single-source direct-expansion (DX) configuration for hot water for space heating or domestic hot water.

A British-Australian research team has assessed the potential of liquid air energy storage (LAES) for large scale application. The scientists estimate that these systems may currently be built at a cost between €300 and €600 per kilowatt-hour and that a positive business case could be favored by certain conditions, including a determined price structure in the energy market and the presence of a grid unable to support high levels of renewable energy penetration.

The maintenance cost of an electric vehicle is estimated to be significantly lower than internal combustion engines, and studies show home solar furthers the cost savings and boosts carbon emission reductions.

Necessity, as it’s said, is the mother of invention. For architect Samira Jama Aden, who plays a central role at Helmholtz-Zentrum Berlin’s BAIP consultancy for building-integrated photovoltaics (BIPV), the need for solar to be part of our built environment is becoming unavoidable. And for Aden, her mission is personal.

Tesla acquired the Californian supercapacitor maker in 2019, leading some to speculate its EVs would use ‘supercaps’ for top acceleration. Two years on, it appears Elon Musk has moved on and sold Maxwell to UCAP Power, but Tesla has retained the company’s dry electrode tech.

Plus there is news this week of a green hydrogen tie-up in India, plans for another German production facility, and of new hydrogen transport networks for Switzerland and the U.S.

The manufacturer has launched sodium-ion products online. Production has begun and will be easily scalable, according to the CATL chairman. Researchers have been keen to make the technology work as it offers a cheaper, more environmentally friendly alternative to lithium-ion products.
