An international research team has designed a residential solar-plus-storage system based on gravity. The system was built with a solar power generator, a bulk booster charge controller, an inverter, a solenoid device, a deep cycle battery, a pulley block, a geared motor, a microcontroller, and wire ropes. Its creators said the system is ideal for regions with high solar radiation. They found that, due to its high electrical requirements, the system needs to rely on high-power solar modules with an output of over 500 W.

Researchers in the United Kingdom have built a 14%-efficient organic PV device that can be used in high-speed optical wireless communication systems. The cell consists of a 4×2.5mm photoactive layer fabricated with a bulk heterojunction of a polymer donor and fullerene and non-fullerene acceptors.

Scientists in the UK used the latest imaging techniques to visualize and understand the process of dendrite formation and electrolyte cracking in an all solid-state battery. With new insight into the mechanisms by which these cracks form and ultimately lead to battery failure, the results could help direct the focus of future research into solid-state battery technology.

Having picked up GBP 5.8 million ($8 million) in a series of investments, U.K.-based Power Roll is pushing ahead with pilot production of an innovative new thin film with which it can manufacture both solar modules and capacitors. In the future, the design could also bring the potential for solar generation and energy storage within a single lightweight device.

A British-Egyptian research group has tested the use of hydrogels beads for PV module cooling. The micro-sized particles were saturated with aluminium oxide (Al2O3) water-based nanofluids and placed below the simulated PV panels. The experiment showed, according to the scientists, that the hydrogels beads were able to significantly reduce the temperature by between 17.9 and 16.3 degrees Celsius.

Green Investment Group, owned by Macquarie, has launched Cero Generation, which will operate on a European scale and carry out both ground-mounted and commercial scale power generation projects. It will also provide integrated energy storage solutions.

UK-based Social Energy launched in Australia with the help of shareholder Shane Warne back in 2019. Now the smart energy firm is being backed with a significant investment from US-based alternative investment fund manager CarVal Investors in order for the company to rapidly grow Down Under.

The £12.7 million project will explore how to transport pure and blended hydrogen for use in heating and industrial purposes. Construction will start next year.

Australia is increasingly at risk of becoming “internationally isolated” with Prime Minister Scott Morrison declaring his government will not be dictated to by other countries on energy and climate policies.

A report by Finnish company Wärtsilä has estimated the potential impact if every dollar committed to a non-renewables energy sector recovery was instead funnelled to clean power.
