Storing renewable energy with thermal blocks made of aluminum, graphite
Newcastle University engineers have patented a thermal storage material that can store large amounts of renewable energy as heat for long periods. MGA Thermal is now manufacturing the thermal energy storage blocks as storage for large-scale solar systems and to repurpose coal-fired power stations.
Module price hike impacting middle-sized PV projects in South Korea
The continuous rise in solar panel prices may affect PV projects of up to 1 MW tendered by the Korea Energy Agency and the domestic solar module industry may not be able to provide the necessary production capacity to respond to the recent supply bottleneck.
China power crisis hits Indian solar projects
After the ravages of Covid-19, electricity shortages in China have now raised costs for its solar manufacturers, with knock-on effects for developers in India too, again highlighting the dangers of relying on a single solar supply chain.
Storing hydrogen with aluminum hydrides
A U.S. research team has sought to improve the way aluminum hydride is used for hydrogen storage. The material was nanoconfined in a framework that is claimed to be able to overcome the challenge represented by the thermodynamic limitation of hydrides in storing the clean fuel.
Cambridge scientists develop Zinc-ion battery that stores solar energy
U.K. researchers have developed a battery with a photocathode made of vanadium dioxide, which is used to harvest light and store zinc ions and zinc oxide as a charge transport layer. The device showed an efficiency of around 1.2% and capacity retention of around 73% after 500 cycles.
When oversized is really the right size
U.S. researchers have concluded that wind and solar generation resources that were sized at 1.5 times along with three hours of energy storage would meet all but 200 hours of demand scattered throughout any given year.
How to clean PV systems covered by volcano ashes
Spanish company Multisistemas E2 has explained how PV systems affected by the volcano eruption in the Canary Islands are currently being cleaned.
Germany has installed 4 GW of PV so far this year
In June alone, new PV additions totaled 406 MW. Feed-in tariffs were reduced by another 1.4%.
H2X to make hydrogen fuel cells, equipment in Australia
H2X, a hydrogen vehicle manufacturer, has announced a deal with Gippsland Circular Economy Precinct in Australia to make a range of hydrogen-focused products. The move comes less than a week after Pure Hydrogen bought a significant stake in H2X Global.
India launches tender for 50 GWh of battery cell output with subsidy support
The Indian authorities have opened global bids to set up advanced-chemistry battery cell manufacturing units in India under the production-linked incentive scheme. Applications are open until Dec. 31, but bidders must commit to setting up a minimum of 5 GWh of capacity to qualify for the government subsidy.
