DNV puts different module formats to the test

Energy consultancy DNV was tasked by module manufacturing giant Longi Solar with comparing the balance of systems costs between modules utilizing 182mm and 210mm wafers, based on a 3.7 MW project in three different layouts. The results reveal a slim cost advantage for the smaller of the two, based on both fixed tilt and tracker systems.

Tesla Powerwalls in California join the movement to create virtual power plants

Made up of distributed residential energy storage, these “plants” stabilize the grid and often end the need for new fossil generation. Tesla customers in California are the latest to join the movement.

Seawater aqueous battery based on alloy of zinc and manganese

Scientists in the United States developed a new anode for aqueous batteries. A working battery utilizing this anode, with seawater as an electrolyte, demonstrated impressive energy density, and remained stable after 1,000 hours of high current cycling. The group is already discussing the potential of their approach in large-scale manufacturing.

Major economies should divert fossil fuel Covid-recovery cash to clean energy before it’s too late

A report by Finnish company Wärtsilä has estimated the potential impact if every dollar committed to a non-renewables energy sector recovery was instead funneled to clean power.

The Texas battery boom

With two new projects clocking in at 100 MW each, the Texas storage market is demonstrating that California isn’t the only U.S. state that can do big batteries.

Chevron turns to renewables to power Australian operations

The power company has announced it will build 500 MW of renewable energy projects to power some of its global facilities under a four-year agreement with Canada’s Algonquin Power & Utilities.

Texan utility tenders 900 MW of solar, 50 MW of storage

CPS Energy has taken the first step towards bringing those volumes – plus 500 MW of firming capacity – to the Lone Star State in pursuit of the power company’s 50%-renewables-by-2040 goal.

A closer look at graphene electrodes

Scientists in the United States have found several shortcomings in the approaches commonly used by scientists to model the structure of electrodes. The group outlines a new approach which it says could lead to the discovery of new materials and combinations that can lead to batteries performing better for longer.

Covid-19 weekly round-up: US job losses raise concern but France and China continued to add new solar

Cell supply shortages could kick-start manufacturing activity in India, EV car sales are braced for a fall while still gaining market share and a new date has been set for the world’s biggest solar trade show.
