Europe’s power price rollercoaster
Almost every weekend since Easter, European generators have been paid to power down plants but some Northern European nations are experiencing record electricity prices. An energy system set up for fossil fuels is in urgent need of reform, according to Gerard Reid, co-founder and partner of Alexa Capital.
Recycling solar panels via supercritical water tech
A Brazilian research group has developed a new method that uses the unique properties of supercritical water to recycle end-of-life solar panels. The scientists claim the novel approach is able to achieve a 99.6% organic degradation, without using toxic or hazardous chemicals.
Computer vision for solar forecasts
A scientific review of solar forecasting with computer vision and deep-learning tech identifies areas for improvement and calls for more collaboration between project developers and grid operators.
Training deep machine learning to identify PV, solar thermal systems in aerial images
A Swedish research group has found that using deep machine learning to identify solar energy systems in aerial images may not be so accurate in non-densely populated countries such as Sweden. They have also found, however, that this technique may be trained via an iterative process and achieve satisfying results.
Benchmarks for solar energy data, methods
The lower the uncertainty in solar resource data, the lower the investment costs. IEA PVPS Task 16 has organized and published two benchmarks to make uncertainty of models and data comparable – a first important step. The benchmarks included modeled solar resource data and methods to fill gaps in measurements.
Infrastructure reform is key to accelerating Africa’s energy transition
In its latestt monthly column for pv magazine, the International Renewable Energy Agency explains that, in order to realize Africa’s vast potential, we must ensure there is adequate investment and infrastructure development to support renewable energy. In the coming years, this means urgently overcoming the structural barriers across three priorities: infrastructure, policy, and institutional capabilities.
The Hydrogen Stream: Researchers test marine green hydrogen feasibility
Mexican researchers have revealed test results for offshore wind-based hydrogen production, while Turkey has started negotiating hydrogen facility partnerships with the United Arab Emirates.
Sage demonstrates long-duration storage with underground reservoirs
US-based Sage Geosystems has presented field results showing that its Earthstore underground storage system can provide 18 hours or more of storage capacity, in addition to short-duration power. The solution is said to be cost-competitive with lithium-ion batteries and natural gas peaker plants.
Agrivoltaic facilities with single-axis trackers have lower LCOE than those with fixed structures
New research from Belgium shows agrivoltaic facilities with trackers perform significantly better than projects with fixed structures. The scientists found projects with tracking achieved an LCOE of €0.077 ($0.082)/kWh, while facilities with fixed structures were found to have an LCOE of €0.10/kWh.
Real-time interface to reduce Netherlands’ grid congestion
All new PV plants over 1 MW in the Netherlands will have to use a real-time interface to make their facilities better communicate with the grid operator starting from next year. Utrecht-based Withthegrid, has developed an interface that is compatible with a number of brand-name inverters.
