Underground hydrogen storage in Canada
A new study has assessed the geological feasibility of large-scale seasonal underground hydrogen storage in Canada and has found that the Western Canada Sedimentary Basin and southern Ontario are the most suitable areas for the technology.
Tokyo Gas issues green bond to fund acquisition of 694 MW of PV
The Japanese gas provider wants to acquire a 63.2 MW solar plant in Japan and a 631 MW PV facility in the United States. It has issued a JPY 10 billion ($95.9 million) green bond to finance these transactions and support its other operations.
Understanding perovskite degradation
Scientists in the US took a closer look at the mechanisms causing perovskites to degrade under light and raised temperatures. By testing perovskite cells with various additives and other recipe tweaks, the group was able to identify pathways to improving long-term stability.
Thermodynamics-inspired model for microgrid feasibility
Researchers in the U.S. have deployed a phase model, inspired by thermodynamics, to total system costs and technology choices of power grids. Doing so allowed the group to make assumptions for when all renewables powered microgrids become the most economically viable option.
SunPower raises guidance after solid Q3 driven by energy storage
It took a pandemic, but the U.S. residential solar and storage industry has finally figured out how to lower customer acquisition costs.
Perovskite-based solar window tech from NREL
NREL’s new solar window darkens in the heat of the sun, producing electricity via embedded perovskite film. The tech is based on formamidinium-based metal halide perovskite, an inherently thermochromic material exhibiting significant optical changes.
REC Silicon could restart poly production at Moses Lake
The Norwegian polysilicon maker has been been frozen out of the Chinese solar market by political tensions between Beijing and the U.S. and mothballed its Washington State production line last year. However, two recent business agreements could change all that.
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.
US startup wins $7.6 million in funding for ribbon silicon furnaces
Leading Edge Equipment Technologies falls in the kerfless solar wafer or direct solar wafer category. Its “drop-in” manufacturing tech cuts wafer costs by 50%, drives up commercial PV power by 7%, and reduces manufacturing emissions by 50%. It’s the emissions piece that may be winning over investors.
Enphase reports 3Q revenue rebound, aided by new storage product
An improved quarter for Enphase was carried partially by the U.S. launch of the Encharge storage system, as well as impressive revenue improvements in the European market.
