India tenders 1.2 GW of wind-solar hybrid projects
Developers have until Dec. 6 to bid to set up a cumulative 1.2 GW of wind-solar hybrid capacity on a build-own-operate basis, anywhere in India.
PV system design for low-cost hot water production
Developed by Spanish scientists, the proposed system design is said to be able to achieve water temperatures above 70 degrees Celsius and to cover around 85% of the annual sanitary hot water consumption of a household with six people.
EDP becomes largest shareholder of Sunseap
The operation is part of the Portuguese utility’s plan to deploy another 13 GW of renewable energy capacity by 2025.
Zinc-bromide battery for stationary energy storage from Australia
Australian startup Gelion is seeking to commercialize a non-flow zinc-bromide battery based on a stable gel replacing a flowing electrolyte. According to the manufacturer, the device is safe, robust and recyclable.
Australia deployed 3 GW of rooftop solar in 2020
Australia broke solar installation records across all rooftop PV sectors in 2020, solidifying its “remarkable” position in the global solar market with the highest per capita capacity, at more 810 W per person.
South Africa gets $8.5 billion to phase out coal, boost renewables
The funds should be allocated through multilateral and bilateral grants, concessional loans, guarantees and private investments. A task force will now seek to identify initial sources of financing for the electricity and coal mining sectors, as well as financing options for the development of electromobility and green hydrogen.
The Hydrogen Stream: The world’s first high-purity hydrogen from biogas
Austrian researchers have demonstrated a chemical looping system can be retrofitted into biogas plants. It is said the new tech can produce high-purity hydrogen for fuel cells on an industrial scale. The scientists concerned said their system could produce hydrogen, on a decentralized basis, for €5/kg.
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.
