![]() At Gravitricity, we are developing an approach to hydrogen storage that is specifically designed to deliver on what these industrial hubs will need. But storing hydrogen is hard, and existing approaches are unlikely to be a good fit in these settings. Large industrial hydrogen hubs are coming our way, and will be key to decarbonisation. This includes improving energy efficiency, reducing greenhouse gases, and generating own energy.Īn alternative approach to hydrogen storage There are many opportunities in the wastewater industry to respond to climate change challenges. Optimising power consumption in wastewater treatment plants Among these trailblazers is Iritron, a renowned technology solutions provider that has established an enviable presence in the field of sustainable solutions. “Necessity is the mother of invention”, and in an era where environmental sustainability has become today’s byword, innovative companies are taking bold steps to reshape the future of energy consumption. Battery storage adds stability to variable energy sources such as wind and solar. ![]() Utility-scale battery storage is becoming the storage method of choice for developed countries such as the US, and rightly so. Solar trailers are emerging as a new alternative energy game changer for small scale farmers who struggle with access to reliable electricity.Įmerson to automate large-scale photovoltaic power projectĮmerson will provide advanced automation solutions to help ensure the safety and reliability of New Zealand’s first large-scale solar photovoltaic (PV) power project. Google is an advocate of ‘urban mining’, the process of extracting critical minerals such as lithium, cobalt and copper from aging mobile phones, laptops and other devices, and reintroducing them into materials supply chains but that won’t be enough to uncover all the minerals and metals to make new Google hardware that is sustainably sourced or to meet the needs of the clean energy systems behind the company’s net-zero goals. Newelec’s LA Series is designed to replace the conventional thermal bimetal protection device, and is far more accurate and longer lasting than anything used before.ĪBB to provide electrification and automation systems for ArcelorMittal Nippon SteelĪBB has been appointed to provide electrification and automation systems for ArcelorMittal Nippon Steel India’s (AM/NS) advanced steel cold rolling mill (CRM) in Hazira, Gujarat. Zinc-based batteries are a new energy storage and conversion technology with significant potential for renewable energy applications. For protection measures to be successful, air-termination conductors on thatched roofs must be installed as elevated traverses, for example: on isolating supports, with certain distances also to be kept for the eaves.įor more information contact Kirk Risch, Dehn Africa, +27 (0), Credit(s)įurther reading: Zinc batteries for renewable energy storage Systems should be designed to provide sufficiently low impedance so that the lightning energy can follow the required route. The latest preferred external protection system for installation on thatched buildings is the high-voltage-resistant insulated lightning protection system that is compact, neat and approved by leading insurance companies and SANS.įor protection measures to be successful, air-termination conductors on thatched roofs must be installed as elevated traverses, for example: on isolating supports, with certain distances also to be kept for the eaves. The company has recently introduced new methods of protecting thatched roofed structures in South Africa, and it is no longer necessary to have a 30 metre long mast installed. Should lightning strike, then current flows through the wire mesh and thermal effects (generated heat) may occur, and set the roof alight.ĭehn Africa can assist in the avoidance of lightning related disasters, and ultimately extend the lifespan of these structures, through the provision of lightning protection system components for use specifically on thatched roofs. ![]() ![]() When a thatch roof is constructed, wire mesh is used to reinforce and secure the bundles of thatch. ![]() However, prior to providing these protective measures, it is important to analyse the risk effects described in standards guide, such as SABS 0313: 1999, SABS IEC 61662-1: 1995 and IEC 62305-2. If recommended protective measures are not considered, the effects of lightning can cause serious damage. Thatch is particularly prone to ignition because it becomes ‘fluffy’ at the surface and, if moist, methane and other flammable gases can be formed. Constructed of material such as straw, reed, grass or coconut leaves, a thatched roof is more susceptible to catching alight as a result of a lightning strike than any other roof type, according to the South African National Standard (SANS). Thatched roofs are extremely popular in South Africa. ![]()
