Norwegian scientists have developed a gallium arsenide (GaAs) nanowire solar cell that can be used as a top cell in a dual tandem cell with a bottom silicon cell. The device is claimed to be the most efficient single-junction GaAs nanowire solar cell grown on a silicon substrate so far.
India headquartered multinational Reliance Industries, through its subsidiary Reliance New Energy Solar Limited, yesterday announced the acquisition of Norway headquartered module manufacturer REC Group. The move comes as Reliance pushes forward with its US$10 billion plan to move in on the renewable energy industry, having also this week announced acquisition of a 40% share in EPC provider Sterling & Wilson.
The manufacturer plans to start production of the performance-enhanced solar modules in August. The first customers should then receive the products in October.
Commodity trader Trafigura and Oslo-based ammonia leader Yara International ASA have signed a Memorandum of Understanding that will see supply of clean ammonia as well as joint R&D projects as the two companies look to promote clean ammonia as a shipping fuel and develop its value chain and infrastructure.
International researchers have analysed the potential of sodium-based energy storage and found recent technical advances have arrived faster than those for the lithium-ion batteries which have been studied for three decades. Issues remain, however, before sodium constitutes a complementary option to lithium.
A report by Norwegian energy consultant DNV GL has considered the opportunity for long-term energy storage to play a role in balancing annual supply and demand fluctuations in a renewables-led grid. Using 58 years of Dutch weather and energy consumption data, the study found long-term solutions such as green hydrogen could make a valuable contribution – but perhaps not as much as some analysts believe.
The Norwegian solar manufacturer is planning to debut its Alpha Series heterojunction (HJT) modules at next week’s All-Energy event in Melbourne. Touted as the world’s highest power 60-cell solar panels, the new series promises over 20% more energy production than other modules with the same footprint and added value for home owners.
New Zealand begins negotiations with four other small nations on trade agreement to remove tariffs on environmental goods, such as solar PV, and eliminate fossil fuel subsidies. The deal would be a world’s first, and another example of the confidence boost New Zealand enjoys during the Rugby World Cup.
The Norwegian solar panel manufacturer says Hanwha Q Cells did not provide full particulars of its allegations despite REC Group’s requests and went ahead to commence proceedings in the Federal Court of Australia.
