The world’s highest hydraulic head in the underground energy storage plant – Pyhäjärvi, Finland

Re-using the deepest base metal mine in Europe enhances Finnish renewable energy storage and climate strategies.  According to a feasibility study report made by Pöyry Energy GmbH this unique project can now be realized. Energy Storage in Mine project financed by the Northern Ostrobothnia Centre for Economic Development, Transport and the Environment (ELY Centers) shows that the underground energy storage plant can be put into practice after the mine closure in late 2019. The concept which is based on pumped hydroelectric energy, closed water circulation and existing mine infrastructure in the 1400 meters depth of the Pyhäsalmi Mine, have “no impact” on the environment. In pumping mode, electric energy is converted to potential energy and stored in the form of water at an upper elevation. Pumping the water uphill for temporary storage “recharges the battery”. Pyhäjärvi energy storage explained in a video here. The estimated construction time of the plant will be 3 years and its operational lifetime more than 50 years. Based on the economic analysis and market modelling of Pöyry Energy GmbH, 75 MW electrical power and 530 MWh capacity would be the most profitable. Installed capacity from 50 MW to 400 MW has been studied. Pyhäjärvi’s future is Storage – a large, mature, and profitable utility-scale technology Pyhäjärvi’s “water battery” is based on mature technology used in more than 96 % of world’s energy storages. In addition to its long operational lifetime, generous size of the energy storage (7 h), high volume of the water reservoir (162 000 m3) and great effectiveness (77 %), it has minimal operating costs with limited maintenance and replacement investments. Distribution of potential income streams from total multimarket trading potential could be 9,5M€/year for 75 MW installation according to the study by VTT Technical Research Centre of Finland. Finland is planning to become the first country in the world phasing out use of coal for energy by 2025 Finland will begin exploring the possibility of phasing out the use of coal in energy production five years ahead of schedule, by 2025, reveals Kimmo Tiilikainen (Centre), the Minister of the Environment, Energy and Housing. Finland’s coal use, he adds, currently falls in its entirety within the scope of the emissions trading scheme of the EU. Because most low-carbon electricity resources cannot flexibly adjust their output to match fluctuating power demands, there is an increasing need for electricity storages in Finland. Pumped storage enables more wind and solar Pyhäjärvi’s plant has the advantage of being able to positively impact all three elements of the energy trilemma: reliability, affordability and emissions reduction. Other technologies such as batteries can meet some but not all aspects. Pumped storage hydropower enables greater integration of other renewables especially wind and solar into the grid by utilizing excess generation, and being ready to produce power during low wind and solar generation periods. It also has the ability to quickly ramp electricity generation up in response to periods of peak demand.

Why effective uniforms are important in the construction industry

While working on a construction site, ensuring the safety of your staff is vital to guarantee that tasks can be done efficiently and safely with as little risk as possible. A thorough health and safety policy can help identify risks, but alongside that, an effective uniform, such as from simonjersey.com, can be a great way to keep your staff safe. From reducing risk of injury, to drastically improving visibility, there’s a lot an effective uniform can provide. Reducing injury risk while on-site An effective construction uniform is one of the best ways you can reduce the risk of injury to your staff while on site. A well-organised, well-managed construction site will often be safer, but there are uniform considerations that you’ll always have to make when there are staff on site. For example, hard hats and sturdy, steel-toed boots are essential for any construction worker. Debris is a frequent concern, which means that protecting the head is vital. Steel-toed boots also fulfil the same purpose if a staff member was to drop a heavy piece of equipment on their foot, for example. They also help staff keep their footing on a construction site, which may have a lot of debris and uneven ground depending on what your business is working on. Visibility and warmth are other key concerns while working on a construction site. During a shift, there can be many people moving around a busy area. Additionally, if you’re working on or near a road, then traffic may be another concern to keep in mind. A thick, padded jacket, worn underneath a bright reflective jacket can be a great combination as part of an effective construction uniform. The warmth will help staff perform tasks efficiently, while the added visibility will drastically reduce the risk of on-site accidents as other staff and the public will take more care when around you. Taking care of employees long-term Staff need to feel as though they’re taken care of it they are to feel safe when working on a construction site. By providing tough and versatile uniform pieces, you’re demonstrating to your employees that you’re doing everything you can to reduce or eliminate risk as much as you feasibly can, and keeping an eye out for their health and safety needs. Think also of the long-term effects that construction work may have on staff if proper precautions aren’t taken. For example, being around loud machinery and using loud tools too often without protection can lead to the development of permanent hearing damage. Using powerful tools like electric saws or jackhammers can lead to nerve and joint damage if the proper precautions aren’t taken. In cases such as this, you can provide ear plugs and ear-protecting headgear, which helps to reduce the noise of certain machinery. You can also provide thick protective gloves which will help maintain good blood circulation in cold temperatures, reducing the risk of vibration damage. Overall health and safety provisions Of course, an effective uniform should always be just one part of your business’s health and safety policies and procedures. While effective uniforms are vital for keeping staff safe and protected, reducing risks as much as you possibly can in other ways alongside the provision of protective uniforms and equipment can help guarantee the safety of your staff while on site. Always look for ways that risks can be reduced before you provide protective equipment of uniform pieces. It may be that you still need to provide protective equipment after you’ve taken those measures anyway, but taking both these steps will help to reduce the risk to staff much more than by just providing protective equipment. For example, when using powerful handheld machinery, consider implementing a policy that states staff must alternate who uses the machinery in short bursts, which can help protect hands from long-term damage. Consider implementing a policy that states you will replace or repair every piece of equipment a certain amount of years after initial purchase, which helps to ensure it’s in great shape and as efficient as possible for the tasks you need to do. Combining an effective uniform with thorough health and safety risk assessments and provisions will help ensure that your construction site is as safe as it can possible be for both staff and the general public.

VIP wins contract double for major tunnelling projects

VIP-Polymers Ltd has won contracts to provide tunnel segment gaskets for two major tunnelling projects in the United Kingdom and India. The global specialist rubber seals and gasket manufacturer has been commissioned to supply its latest cast-in gasket for the 12.7km Thames Tideway Central wastewater tunnel in London. VIP, based in Huntingdon, Cambridgeshire, UK, has also won a contract to supply tunnel segment gaskets for a project to extend the Mumbai Metro. Matthew Levitt, VIP Technical Business Development Manager, said: “Our success with both projects demonstrates our ability to deliver a wide range of innovative products and technologies for supporting major water and transport infrastructure projects anywhere in the world. “These are exciting tunnelling projects that are vital to the sustainable development and growth of two great cities, and we’re delighted to be involved with them.” Thames Tideway Central is the longest of three sections of a 25km tunnel, due for completion in 2024, designed to prevent the discharge of untreated storm water and sewerage from 34 combined sewer overflows into the tidal River Thames. VIP is supplying its cast-in gasket referenced VIP028CI with patented corners to tunnel segment pre-caster Pacacar for the section, which will be 12.7km long, with an inner diameter of 7.8m. Supply commenced in December 2017. A consortium made up of Ferrovial Agroman and Laing O’Rourke (FLO JV) is the main contractor for the central section, which runs from Fulham to Blackfriars and will have 6,100 tunnel segment ring sets. VIP’s compliant compressible corner technology for cast-in gaskets delivers consistent load performance along the entire perimeter of the gasket. This eliminates the risk of high loads at one or more of the gasket’s corners during installation, which could contribute to segment cracking. The technology has already been proven on other tunnelling projects, including the 5km Shieldhall wastewater tunnel in Glasgow, commissioned by Scottish Water. VIP has been commissioned by J Kumar Infraprojects to supply tunnel segment gaskets for the Mumbai Metro Line 3 (Packages 5 and 6) tunnel, which is being built for the Mumbai Metro Rail Corporation, a joint venture between the Indian Government and the Government of Maharashtra. The project involves the construction of a 4.5km twin tunnel, with an outside diameter of 6.6m, requiring a total of 17,800 tunnel segment ring sets. Production of the glued-in gaskets selected for the tunnel has already begun at VIP’s factory in Huntingdon. This latest contract continues VIP’s long-standing position as a major supplier of TSGs in India, having previously supplied four phases of the Delhi Metro project and the Ghatkopar High Level Tunnel in Mumbai. Matthew Levitt said: “The gasket has been specifically developed as a modification of our VIP024 gasket to provide additional sealing assurance sought by project engineers as the tunnel passes under the Mithi River.” www.vip-polymers.com +44 (0)1480 411333
