      UK Gov Stumps Up £20m to Crack Electricity Storage Challenge

      A £20 million ($26m USD) competition has been launched to give a boost to innovative ways of storing electricity, the UK Government has said. It aims to scale up technologies to compete with current storage methods – lithium batteries and pumped hydro. Announcing the competition for innovators, the Business Department said energy storage was the next essential green technology, which would allow the UK to make the most of its growing renewable power sector.

      Flexible Energy Storage Solutions

      Thousands of megawatt-hours of electrical energy squirreled away into utility-scale energy storage plants to cover the spread between generated renewable energy and the lowest reliable operating limit during the 10 a.m. to 3 p.m. “duck curve” period of the day — does this sound like a glimpse into the far future of major utilities across the United States and the world? But the future has already arrived at the Carolina operating companies of Duke Energy. The Duke Energy Progress Company, serving customers primarily in the eastern half of North and South Carolina, managed a whopping 106 GWh of excess energy in 2017, largely generated from utility-scale solar in North Carolina, using pumped hydro energy storage.

      Cemex R&D Subsidiary Sees the Ups and Downs of Energy Storage

      Crane-suspended concrete segments, patterned like an enormous stave silo, power a commercial scale-ready system based on what Swiss developer Energy Vault describes as “the principles that underpin traditional gravity-based pumped hydro plants.” Software operates an automated six-arm crane and orchestrates positioning of the concrete segments that provide the basis for efficient electricity storage and discharge. The use of low cost and environmentally-friendly concrete materials enables the system to achieve low cost per kilowatt-hour and high round trip efficiency while delivering a 30-40 year life without any degradation in storage capacity. Energy Vault figures that a properly configured system will be capable of reaching 100 percent of target power levels in 2.9 seconds.

      Battery Storage Already Competitive With Pumped Hydro, Says Arena

      As Australia’s renewable energy industry awaits the imminent outcome of the South Australian government’s inaugural large-scale energy storage auction, the CFO of the Australian Renewable Energy Agency has described two of the key competing technologies – large-scale battery systems and pumped hydro – as neck and neck on pricing. Speaking at the 2017 Large-Scale Solar Conference co-hosted by RenewEconomy and Informa in Sydney on Monday, ARENA CFO Ian Kay said projects pairing 100MW of renewable energy generation with 100MWh of energy storage were “about equal” in cost.

      Scottish Power to Double Size of Cruachan Hydro Power Station to Store Renewable Energy

      SCOTTISH POWER plans to more than double the size of a hydro-electric power station built inside a mountain to help store renewable energy. The firm said a feasibility study shows Cruachan hydro power station in Argyll can be expanded - increasing its current generating capacity from 440mw by 400-600mw. But costs of up to £400 million will halt the development unless ScottishPower can secure a guaranteed floor price for its use from the Government, in return for a cap on profits.

      Spanish Island's Run of Four Hours on 100% Renewables 'Very Significant', Says IRENA Expert

      While a project to run a Spanish island off renewable energy which gathered media attention this week might only have successfully met the region's energy demand continuously for four hours, the project is nonetheless "very significant", an expert with the International Renewable Energy Agency (IRENA) has said. Spain’s El Hierro, the most southerly of the Canary Islands, used a combination of only wind, hydro and energy storage to meet the energy needs of all of its 10,000 locals for four hours earlier this month.

      Calgary-based Rocky Mountain Power has been working on the Alberta Saskatchewan Intertie Storage Project (ASISt) for a couple of years. Company president Jan van Egteren said because of regulatory procedures, it'll likely be another two or three years before the company actually breaks ground on the project. While using salt caverns for storage purposes is not new – they are often used to store liquid petroleum products such as butane, as well as the by products of oil production. What is new is employing the caverns to store wind energy.

      Pumped Hydro – the Forgotten Storage Solution

      Storage is in the energy news now, in more places than can be listed. To pick a few, here is recent news from Europe, Tesla, and Queensland.  Everyone is looking to the day when battery technology can economically partner with the popular yet variable renewables: solar PV and wind. But what if today there was a proven way to store vast amounts of energy at capital costs lower than what battery technologists hope they might achieve in 20 years time? A technology with high round-trip efficiency and one heck of a lifespan: 85 years and counting!
