Corvus Energy is pleased to announce that the company has been selected by Holland Ship Electric to supply lithium ion battery-based energy storage systems (ESS) for five new all-electric ferries being built by Holland Shipyard Group for Amsterdam's municipal public transport provider, GVB. The ferries will operate on three of the North Sea Canal routes, replacing the current fleet built...

While the power conversion efficiency of perovskite solar cells (PVSCs) - a future of solar cells - has already greatly improved in the past decade, the problems of instability and potential environmental impact are yet to be overcome. Recently, scientists from City University of Hong Kong (CityU) have developed a novel method which can simultaneously tackle the leakage of lead from PVSCs and...

By studying 488 public airports in the United States, University of Colorado Denver School of Public Affairs researcher Serena Kim, PhD, found that 20% of them have adopted solar photovoltaic (PV), commonly known as solar panels, over the last decade. Solar photovoltaic (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect...

New heat-harnessing "solar" cells that reflect 99% of the energy they can't convert to electricity could help bring down the price of storing renewable energy as heat, as well as harvesting waste heat from exhaust pipes and chimneys. The energy storage application, known informally as a "sun in a box," stores extra wind and solar power generation in a heat...

Understanding how solar cell operation changes as it moves from the lab into the real world is essential for optimizing their design prior to mass production. KAUST researchers show how perovskite/silicon tandem solar cells function in a sunny and hot environment. Silicon dominates commercial solar-cell production. It is abundant and efficient as a converter of light to electricity...

Solar cells have come a long way, but inexpensive, thin film solar cells are still far behind more expensive, crystalline solar cells in efficiency. Now, a team of researchers suggests that using two thin films of different materials may be the way to go to create affordable, thin film cells with about 34% efficiency. "Ten years ago I knew very little about solar cells, but it became clear...

Batteries fade as they age, slowly losing power and storage capacity. As in people, aging plays out differently from one battery to another, and it's next to impossible to measure or model all of the interacting mechanisms that contribute to decline. As a result, most of the systems used to manage charge levels wisely and to estimate driving range in electric cars are nearly blind to changes in...

The commission passed its long-awaited rule on distributed energy resource aggregations in a 2-1 vote two weeks after the departure of Commissioner Bernard McNamee.

Phoenix Contact предлагает облачную аналитическую систему на основе Интернета вещей

Phoenix Contact предлагает Proficloud - открытую систему на основе Интернета вещей (IoT), которую можно эффективно использовать в любой отрасли промышленности. Речь может идти об облачном сборе и анализе данных или о комплексной концепции автоматизации. Шлюз IoT обеспечивает связь с Proficloud, не затрагивая логическую схему автоматизации. Благодаря согласованному взаимодействию аппаратной части шлюза и облачной платформы осуществляется сбор показаний датчиков и технологических данных, их шифрование и передача в облачные приложения для последующей обработки. Шлюзы IoT могут передавать в Proficloud и данные состояния уже существующих установок, поддерживая работу приложений для обработки больших данных, распознавания образцов, мониторинга условий и т. д. Это позволяет достичь нового уровня эффективности производства. Облачный шлюз Cloud IoT Gateway легко настраивается с помощью веб-интерфейса самого шлюза. Дополнительное ПО для настройки не требуется.
