A closer look at liquid air energy storage
A British-Australian research team has assessed the potential of liquid air energy storage (LAES) for large scale application. The scientists estimate that these systems may currently be built at a cost between €300 and €600 per kilowatt-hour and that a positive business case could be favored by certain conditions, including a determined price structure in the energy market and the presence of a grid unable to support high levels of renewable energy penetration.
AC Energy, NEFIN partner to build rooftop solar projects across Asia
Philippines-based AC Energy, which operates 150 MW AC ground-mount solar plants in India, is joining hands with Hong Kong-based solar developer NEFIN to develop, construct, and operate rooftop solar projects across Asia.
Four-terminal heterojunction perovskite tandem solar cell with 30.09% efficiency
Developed by a Vietnamese-Korean research group, the complex PV device was built with a bottom bifacial crystalline silicon perovskite-filtered heterojunction sub-cell that is able to absorb all solar spectra in the short-wavelength range.
Renew Power to build 500 MW of open-access renewable energy project for RackBank data center
The Haryana-based developer will construct, own, and operate up to 500 MW of hybrid renewable energy generation capacity to meet the requirements of RackBank’s hyper-scale data center.
EverSource-backed GreenCell to deploy 3,250 electric buses in three years
The company will initially launch 750 electric buses across key intercity and inter-state transit routes in Southern and Western India. To support the e-bus rollout, it is also building a captive charging infrastructure network across highways with 600 DC chargers of 180/240 kW capacity rating.
Local solar will lead the energy transformation over the next five years
The adoption of local, community-based energy solutions like rooftop solar and batteries can help make the energy grid more flexible and reliable. Home solar and batteries will enable the growth of ‘prosumers’ who produce and share energy, as well as consume it.
Foreign investors tapping into India’s solar market undeterred by untimely payments
Full ownership allowed in renewable energy projects and 25-year power purchase agreement are the major factors drawing foreign investors to India’s high-growth solar market. Major developers in India have solar portfolio distributed across States, which further minimizes the risk for investors.
Meyer Burger plans to launch solar PV roof tiles in 2022
The Swiss group has acquired an integrated solar roof system solution from an unidentified German engineering service provider for this purpose. The aim is grow this sector from a niche market.
Canada’s OMERS Infrastructure to buy 19.4% stake in Azure Power
The transaction expands Canadian pension plan’s investment in clean energy, consistent with its long-term strategy to increase footprint in this growing sector.
India offers fastest energy payback on silicon solar rooftop systems
The energy payback time of a silicon PV rooftop system mounted in India is only 0.44 of one year (160.6 days), compared to 0.53-0.67 year in Africa, 1-1.3 years in Europe, and 1.42 years in Canada, reveals a world map by German research body the Fraunhofer Institute of Solar Energy Systems (ISE). For the calculation, the report authors considered the installation used a typical, Chinese-made, 60-cell, PERC, 19.9%-efficient solar module.
