As the PV industry scales to annual terawatt-level production to rapidly curtail the world’s emissions, it will become more challenging to continue the cost reduction trajectory. Increasing module production from current levels of 200 GW to 300 GW to several terawatts each year will consume significantly more material resources than the industry currently uses. This will require consideration of the additional materials to be sourced, writes Alison Lennon, chief scientist at Sundrive Solar and professor at the UNSW’s School of Photovoltaic and Renewable Energy Engineering.
Batteries are set to drive the energy and mobility transitions. Worryingly, when they degrade early or excessively – particularly because of misuse – it can be costly. Claudius Jehle, the CEO of volytica, explains how a better understanding of batteries can prevent expensive mistakes.
Net metering reforms in the US are a missed opportunity to harness residential battery storage, argue researchers from the Lawrence Berkeley National Laboratory. Compensation rules for residential rooftop solar are evolving toward a model that encourages customers to use battery storage to maximize solar self-consumption. However, is this a good thing? Galen Barbose, Sydney P. Forrester, and Chandler Miller investigate.
H2X Global has released the first of its hydrogen-powered generators in the Australian market.
The rise of electric vehicles brings rapid technological advancement and cost reductions to lithium ion battery manufacturing, which can serve to make batteries more useful and more profitable for the energy storage industry. However, the use of stationary batteries as energy assets is still at a nascent stage. Most markets and business models are immature, and InfoLink analyst Yuan Fang-wei sees policy as the major driving force to lead and stimulate China’s energy storage market.
As sales of Li-ion batteries accelerate, both governments and the largest battery manufacturers are beginning to grapple with the question of whether local manufacturing facilities are desirable or even necessary. Although this appears to buck the trend of technological development over the last few decades, there are a number of technical as well as geopolitical reasons that make this a major issue for all Li-ion battery manufacturing stakeholders. Everoze partner Jamie Shaw-Stewart explores some of these issues.
At the end of 2021, the total capacity of the solar power plants throughout the world was estimated to be 940 GW. According to the forecasts of solar association SolarPower Europe, the total capacity could reach 2 TW by 2025. With the rapidly growing popularity of solar power plants, experts predict that the next breakthrough in this sector will be smart batteries. In the future, solar power plants will not be able to operate without them.
Australian-born vanadium redox flow technology and new homegrown electrolyte sources are set to bulk up renewable energy storage options in the Pacific region and plug the gap left by lithium supply-chain issues. Natalie Filatoff reports from Sydney.
UK researchers have revealed that gaseous hydrogen could cause problems in natural gas pipelines, while electrolyzer manufacturer Nel has announced plans to build a second production line in Norway.
