Research from Cornwall Insight’s Renewables Pipeline Tracker reveals there is ample evidence of developer appetite for future renewables investments in the UK. The research highlights the total capacity of tracked sites in the pipeline stands at 38.7GW across 845 locations. The majority of projects are classed as ‘awaiting construction’, accounting for 22.9GW of the pipeline. Lucy Dolton, Analyst at Cornwall Insight, said: “Unsurprisingly, more established technologies such as battery storage, solar PV, onshore and offshore wind currently dominate those projects progressing to ‘awaiting construction’, but also to ‘under construction’ and ‘operational’ development statuses. “Of the 38.7GW pipeline, the data shows 3.2GW have confirmed Transmission Entry Capacity (TEC) to connect to the system. A further 66% is forecasted to connect at the transmission level, if developed, with the remaining 33% at distribution level. “Standalone battery is a key pipeline technology, accounting for the largest share by technology type in 8 out of 14 DNO regions, followed by solar PV. Offshore wind is expected to dominate transmission connections, but, notably, more large-scale onshore wind and even solar PV assets are likely to seek transmission connections. This is likely due to the economies of scale new sites are looking to achieve, especially those going subsidy-free. “Integral to the development

Hamburg, 18 May 2020. The Nordex Group will be the supplier for Vattenfall’s largest onshore wind farm in the UK. The 240 MW South Kyle wind farm in Scotland will consist of 50 N133/4.8 strong-wind turbines, and the Group will maintain the machines on the basis of a Premium Service Contract with a term of 10 years. The Nordex Group booked the contract for this project in the first quarter of 2020, and the company’s regular customer Vattenfall has now given the green light for the construction of the wind farm. The South Kyle Wind Farm will be built on land largely utilised for commercial forestry. Located 5km to the east of Dalmellington and between East Ayrshire and Dumfries and Galloway. The Nordex Group will install the 50 turbines on tubular steel towers, with a blade tip height of 149.5 metres. “Vattenfall is a very important partner for our activities in Europe. We are pleased to equip South Kyle with the strong-wind N133/4.8 turbine from the Delta4000 series. Our highly efficient technology is particularly important to maximise electricity production," says Patxi Landa, CSO of the Nordex Group.

The first project to be supported by the broader manufacturing plant will be the 300 MW Hai Long 2 project. The expansion is subject to certain conditions including Hai Long 2’s Industrial Relevance Proposal (IRP) being approved by the Taiwanese authorities, and final investment decision by the project partners. Siemens Gamesa was named as preferred supplier for the offshore wind turbines in November 2019. The facility is currently under construction and will start production in 2021 to deliver nacelles to Orsted’s Greater Changhua 1&2a offshore wind power project. Once the nacelle assembly

String inverter leader builds new factory to meet global demand for solar Zhejiang, China – May 13, 2020. Ginlong Technologies (Stock Code: 300763.SZ), a global leader in photovoltaic string inverter manufacturing, announced plans to raise over $100M USD (» 700M Chinese Yuan), through a non-public offering to finance the expansion of its manufacturing capacity. Facing a rise in the global string inverter market, Ginlong will use these funds to double its production capacity of Solis products to 20GW per year. This expansion will enable Solis to boost its supply to grid-connected and solar-plus-storage projects for customers world-wide. “The demand for our ultra-reliable Solis inverters has driven this push to double our capacity,” says Yiming Wang, Ginlong President. “We are seeing a boost in demand for string inverters over other technologies due to its cost-competitiveness and reliability. This doubling of our production represents an exciting milestone for Solis.” The expanded factory will add 1,000,000 square feet to its existing facility in the Binhai Industrial park, bringing the company’s total capacity to 20GW.

Understanding the differences between electrocution and Arc Flash injuries is the first step in understanding why you need different protection from the two types of incident. Here Mark Lant, technical expert at ProGARM, explains what happens when you’re electrocuted and how that differs from an Arc Flash. What happens when you’re electrocuted? Electrocution can cause a wide range of injuries, as it blocks electrical signals between the brain and the rest of the body. From just creating a tingling in the part of the body where the electric current enters, to causing death, the spectrum of injuries is broad. The Health and Safety Executive (HSE) says that a voltage as low as 50 volts which passes between two points in the body can cause any of the following symptoms: Electric shock – this can cause a person to stop breathing, muscle spasms (which can themselves cause bones to break), loss of muscle control meaning the operative can’t let go of what’s electrocuting them, and the heart to stop beating properly. Muscle, nerve and/or tissue damage Thermal burns at the source of the current Electrical burns caused by the current passing through the body, heating tissue as it goes. Electrical burns can be deep and often

A research team led by Prof. Yi-Chun LU from the Faculty of Engineering at The Chinese University of Hong Kong (CUHK) has taken a critical step forward in improving high-energy batteries by introducing a novel electrolyte to the aqueous lithium-ion (Li-ion) battery. This electrolyte is commonly used in skin cream. It is inexpensive, inflammable, less toxic and is eco-friendly, yet can create stable voltage for common usage. The breakthrough was recently published in the world-leading scientific journal, Nature Materials, a sister journal of Nature. The transformation of the Li-ion battery: from flammable organic to aqueous  In electronic devices and gadgets such as cell phones and laptops which have improved our daily lives on many levels, you can always find a Li-ion battery. As a result of the rechargeable characteristics and stable energy output, they have become the heart of these electronics. Despite years of research, Li-ion batteries still heavily rely on toxic and flammable organic electrolytes to produce power, and the serious safety hazards remain unsolved. The Samsung smartphone explosions and batteries on fire in a novel Boeing plane are just a few examples. These incidents have indicated that the safety of Li-ion batteries is not yet assured. In contrast, aqueous Li-ion batteries
