Bill Nussey describes in his new book a much larger role that he foresees for local solar and storage, and a correspondingly altered role for electric utilities.

New research from the U.K. shows the increasing competitiveness of long-distance hydrogen interconnectors over the next three decades. Compared to high-voltage electricity cables, hydrogen interconnectors may soon achieve a much lower levelized cost of storage and their ability to further reduce the final LCOE will depend on how much electrolyzer costs will reduce over the years.

German scientists have developed a perovskite PV cell with remarkable stability by adding a bilayer of polymers that protects the perovskite from corrosion. This design helps to shield the extremely sensitive perovskite interface and provides the cell with extraordinarily high conductivity.

An international research team has investigated how solar could be combined with thermoelectric coolers (TECs), which are small solid-state heat pumps used either for heating or for cooling. A system was built with six solar panels, an air duct system, four batteries, a charge controller, TECs, an inverter, heat sinks, a test chamber, and condenser fans.

A massive solar noise barrier in the US state of Massachusetts is expected to generate 802,000kWh of electricity per year, or the equivalent of annually supplying 120 homes with power.

Scientists in Australia have analyzed the state-of-the-art of all gettering technologies used in the solar industry. This technique, which is aimed at reducing defects in wafer manufacturing, may become more important in the future, as cell efficiencies increase and become increasingly sensitive to traces of metallic impurities.

Egyptian researchers have analyzed all cooling techniques for solar module cooling. Their review includes passive and active cooling methods, cooling with phase change materials (PCMs), and cooling with PCM and other additives, such as nanoparticles or porous metal.

Nickel-zinc batteries will be coupled with wind power to support 30MW of critical IT load at a data center in Wyoming, in the US. The batteries’ lifespan can be up to 15 years, while its roundtrip efficiency stands at 85%.

According to BloombergNEF, electrolyzer shipments may reach up to 2.5GW in 2022, up significantly from 458MW last year. China and the United States will become the world’s first and second markets, respectively.

According to PVInfolink, the top 10 solar manufacturers accounted for over 160GW of shipments or a global market share of 90% in 2021.
