Amid significant environmental concern about the impact of more widespread lithium mining, various methods of extracting the battery material from brine could offer a cleaner solution – and reignite a historic Cornish industry.
Uniper says it has launched its Hydrogen Pilot Cavern (HPC) Krummhörn plant in Germany with nearly 500,000 cubic meters of green hydrogen storage, while Air Liquide has inaugurated a 20 MW electrolysis plant in Oberhausen, Germany.
A survey of 1,797 residents was used to determine the willingness to pay for low-carbon residential heating in the Netherlands. On average, respondents were willing to pay a premium of 33% for electricity-based heating. Policy recommendations were also provided as part of the study.
Researchers in Morocco have carefully configured and tested a novel desert solar module optimized for harsh desert climates. The new design delivered a 5.8% improvement in performance ratio, a 1.95% increase in efficiency, and reduced temperature sensitivity by 0.85% compared to standard modules.
New research from Switzerland shows that capex costs for Alpine PV projects in Switzerland currently range between €2,231/kW and €4,182/KW for ground-mounted projects and up to €3,802/kW and €7,108/kW for wall-mounted and floating projects, respectively.
Japan’s Sekisui Chemical launched an agrivoltaics project in partnership with Terra, a unit of Japan-based Citizen Energy Chiba, to test the peformance of its perovskite solar cell technology and the effect of the PV system on plants.
A research team from Japan and Indonesia used satellite data to investigate fluctuations of solar irradiance over the Asia Pacific region and draw conclusions on which areas are best suited for future installations.
Conceived by Chinese scientists, the cell was built with new surface reconstruction strategy based on the use of 1,4-butanediamine (BDA) and ethylenediammonium diiodide (EDAI2) as surface modifiers. The device was able to retain 79.7% of its initial efficiency after 550 h.
Varta says it now expects high demand for its Varta.wall DC high-voltage battery. It initially presented the product at Intersolar 2022, but has struggled with its market introduction.
The proposed system uses compressed air to store energy, as well as for the prevention of clogging in the irrigation tubes. Two experimental systems were built and tested in China and clogging was reduced by up to 93%.
