Tracking is crucial to concentrating photovoltaics (CPV), but can it enable the technology to earn a larger portion of the solar power sector? Key players in the trackers field tell us where the sector is focused, and how it is coping with the challenge of low-cost PV.
Operations and Maintenance (O&M) – it's a crucial aspect of any renewables project and represents a sizeable proportion of the overall cost of a typical installation. What's more, the topic of maintaining renewables assets, especially in the offshore environment, is something that is only going to grow in importance. With more and more new schemes coming on stream, and a continued global push – driven in part by governments such as that in Germany – for electricity generation schemes to be located in our seas, the techniques used to complete maintenance effectively and minimise downtime will doubtless be developed and refined in the coming years.
Even though many climate models hint that the coming El Niño may rival or even surpass the El Niño of 1997-98, the forecasted rainfall may still be unpredictable. However, what remains true is that the past decade of catastrophic wildfires and drought have left a parched landscape ill prepared for torrential rainfall, which can quickly create significant problems for solar and wind projects across the globe. This means site assessments and maintenance practices are a crucial aspect of El Niño preparation.
Nearly a year ago, the New York Public Service Commission (Commission) initiated a groundbreaking effort, called ‘Reforming the Energy Vision’ (REV), to overhaul the longstanding electric utility business model. In the months since starting the REV proceeding, the Commission has sought advice from Department of Public Service staff, industry stakeholders, and environmental non-profits, among others, quietly refining its vision while largely refraining from big pronouncements about the progress of the proceeding.
If you live in a rural area of southern India, two lights can literally save your life.
Manufacturing rotor blades for very large turbines is a highly complex procedure. Transporting and handling then brings another set of challenges. Eize de Vries reports on REpower's joint venture that will exclusively manufacture rotor blades for the company's on and offshore machines.
While developing the new 194.2-mw Venda Nova II pumped-storage project in Portugal, Energias de Portugal, S.A. used several innovative civil engineering techniques to design and build the power tunnels, support the powerhouse cavern roof, and excavate the upper surge shaft.
A series of recent reports from the UK calls for commitment and effective policies to support energy storage deployment across the country. In one report — Energy Storage in the UK: An Overview — the Renewable Energy Association (REA) observe that UK energy storage capacity stands at a total of 3.23 GW via some 35 grid-scale storage projects and over 1,500 residential storage systems.
Sure, solar-electric systems can contribute extra power to smooth out peak demand on the electric grid, and lower electricity costs for a business, but it's less often that solar is used as the primary power source for crucial energy aspects of an industrial operation.
Rapid charge, long life batteries made from low-cost and abundant aluminum are set to emerge from research led by Taiwan’s Industrial Technology Research Institute. Unveiled at the recent All Energy event in Glasgow, aluminum ion batteries could displace the lead-acid batteries commonly found in automotive applications in just two years.
