Before Puerto Rico had a chance to recover from Hurricane Maria, in 2017, it was rocked by earthquakes and then, in September 2022, the island was struck again – this time by Hurricane Fiona. These disasters severely impacted Puerto Rico’s infamously fragile power grid, but have emboldened local communities to take power into their own hands through solar and battery storage, and increasingly in the form of microgrids. Compelled by catastrophic circumstances, Puerto Rico must now push toward energy resilience and in the process may see itself become a model not just for other islands, but mainland grids as well.

The Australian Renewable Energy Agency’s recent funding spree has continued after it awarded a further $1.04 million (USD 700,000) to the University of Wollongong for a project that will look to develop national standards for harmonic compliance assessments. The current and rather ad hoc methodologies are proving incapable of addressing the challenges brought with increased renewable energy integration.

World-leading solar researcher UNSW Scientia Professor Martin Green says that PV research activities in Australia right across the value chain will be accelerated by the recent $41.5 million (USD 28.5 million) funding awards from the Australian Renewable Energy Agency. The funding will foster the development of ultra-low-cost solar by extending and expanding nine UNSW solar research programs.

Gravitricity, an Edinburgh-based storage specialist, aims to develop the first full-scale demonstration of its underground hydrogen storage solution by working with structural engineering contractor VSL Systems UK.

Chinese scientists have developed a new way to split seawater into hydrogen without using a separate desalination process. They incorporated a self-breathable waterproof membrane and a self-dampening electrolyte (SDE) into the electrolyser, so water migrates from the seawater across the membrane to the SDE, without extra energy consumption.

Erthos claims that with its new installation method, solar facilities could occupy just one-third of the surface covered by conventional PV plants, potentially reducing installations costs by up to 20%.

The strength of applications for the Australian Renewable Energy Agency’s ultra-low-cost solar research funding round was so strong the agency had to add $1.5 million (USD 1.03 million) to its original allocation. The strength of competition pushed the process into 2023, but now the 13 research projects aiming to achieve ultra-low-cost solar have been awarded.

Researchers from the University of New South Wales have been tapped to work with European space enterprise Airbus Defence and Space on a strategic research program to fast track the development of high-efficiency solar cells to be used in space.

A recently published report from the International Energy Agency’s Photovoltaic Power Systems Programme on building integrated photovoltaics (BIPV) digitalisation found many industry professionals are unsure of a suitable method for estimating shading in BIPV projects.

Longi said it has achieved a 26.56% efficiency rating for a gallium-doped, p-type heterojunction solar cell and a 26.09% efficiency rating for an indium-free HJT cell, both based on M6 wafers. Germany’s Institute for Solar Energy Research in Hamelin has confirmed the results.
