Record energy prices, particularly in Europe, are driving demand for renewables and energy storage. That is changing the equation for utility solar and wind investment and shortening project payback times to under a year in some regions. Storage deployment, driven by recent policy developments around the world, is also expected to get a big boost through to 2030.

Chinese scientists have built a selenium solar cell with an alloyed selenium-tellurium absorber, which reportedly reduces interfacial defects. Under standard illumination conditions, the device has an efficiency of 1.85%.

The first post-pandemic update on the state of the world’s off-grid solar industry has painted a picture of domination by European companies, but highlighted the potential for new startups in West Africa and an increasing use of PV as a backup to unreliable grid supplies.

Portuguese startup Solarud has unveiled the next generation of its water-draining device for PV panels with low, sloping inclines. The new design avoids clogs caused by sand and dust, in nano and customized versions that fit installations and modules of different sizes.

The Clean H2 Infra Fund has closed with new investors to mobilize up to €20 billion ($19.4 billion) of investment capacity over the next six years for heavy mobility and energy-intensive industries. Toshiba has revealed new production tech for electrolysis electrodes that slashes iridium use, while Hyundai Heavy Industries has kicked off a demo project for fuel cell vessels.

Scientists result have confirmed a 22.2% efficiency rating for a flexible CIGS solar cell with Germany’s Fraunhofer Institute for Solar Energy Systems.

The off-grid solar sector has shown resilience in the face of pandemic-related challenges, with 70 million people gaining access to electricity from early 2020 to the end of 2021. However, the ability to pay for solar energy kits has taken a hit.

Scientists at Germany’s Fraunhofer Institute ISE and a consortium of heat pump manufacturers have achieved a new efficiency record in their development of a low-refrigerant propane refrigeration circuit. The device has a heating capacity of 12.8 kW with only 124 grams of propane, amounting to a refrigerant charge of approximately 10g/kW, compared to 60g/kW for commercially available devices.

US researchers have developed a novel fast-charging battery anode material, and GM has revealed a new focus on battery R&D. The European Parliament, meanwhile, has issued a number of proposals for alternative fuels infrastructure.

When choosing a solar power plant, individuals and businesses pay the most attention to its power – after all, this will determine how much electricity will be produced. Other equipment, systems and sensors that allow monitoring and analysis of the operation of the power plant are often underestimated. But they shouldn’t be: the solar power plant will be used for several decades, so various failures and poor-quality monitoring can have a significant impact on the efficiency of electricity production.
