Hydrogen storage in vertical caverns
Australia’s Energy Estate has signed a new agreement with Abergeldie, which designs vertical man-made caverns for hydrogen storage. The partnership will focus on a range of projects, including a 1.6 GW hydrogen network.
Quantitative methodologies to assess technical risks in PV
Researchers led by Germany’s TÜV Rheinland have created a database of technical risks and mitigation measures for PV installations. Their broad overview of quantification methods has shown that further standardization is required.
Most new solar panels retain 80% production after 30 years
A five-year Sandia Labs study on solar module degradation shows that 13 out of 23 tested module types have effective lifetimes exceeding 30 years.
New study looks at Sundrive’s 25.54% silver-free heterojunction solar cell
A new scientific paper takes a closer look at the record-breaking efficiency that Australia’s Sundrive announced for a silver-free heterojunction cell in September 2021, as certified by Germany’s Institute for Solar Energy Research.
Singapore to adopt solar forecasting model
Scientists have completed a one-year trial of a model that calculates solar irradiation forecasts up to 24 hours in advance. Singapore’s Energy Market Authority now plans to adopt solar irradiance forecasting, as the model has an average error rate below 10% for one-hour forecasts.
Tech advances halving surface needed for ground-mount solar
French developer VSN Energies Nouvelles was able to almost double the capacity of one of its PV projects due to technological advances such as high-powered panels and new plant design concepts.
Rooftop-mounted microgrid combines wind, solar, storage
Hover’s first 36 kW installation survived the recent Hurricane Ian storm system that ravaged southwestern Florida.
Inverted perovskite solar cell with 21.85% efficiency via surface modulator
A UK research group has used surface modulators to reduce non-radiative recombination in perovskite solar cells. They used 2-TEAI organic halide salt to build a cell with high power conversion efficiency and stability.
PV-powered thermoelectric cooling for air conditioning in buildings
Scientists have proposed a way to combine thermoelectric modules (TEMs) with rooftop PV to support heating, ventilation and air conditioning in buildings. They designed a wall-integrated TEM to heat and cool adjacent rooms.
New polymer-based battery electrodes with high stability
UK researchers have developed organic electrode materials to integrate redox-active organic molecules into long-chain polymers. The new electrodes exhibit better cycling performance in lithium-ion batteries, with no apparent capacity decay over more than a thousand charge-discharge cycles.
