Elcogen, Convion and Lempäälän Energia to develop fuel cell energy system
/ Estonian fuel cell manufacturer Elcogen and Finnish fuel cell system developer Convion partnered to power two combined heat and power (CHP) systems at the Lemene smart
Led by Finland-based energy company Lempäälän Energia, the grid is one of the key projects designated by the government to help the country reach its national energy targets for de-carbonisation.
Lempäälä Energia CEO Toni Laakso said: “The Lemene system will operate mainly as part of the public electrical grid but can also operate as a supporting reserve system for the public electrical grid, or independently off-grid, on demand.
“The Lemene smart grid will feature a variety of smart technologies that will respond to changing electric demand, enabled by automation solutions adapted to the microgrid. An important part of the project is to secure energy availability as renewable energy production varies.
“In conjunction with the solar array and battery storage, the Lemene system also required a highly efficient CHP system from Convion that would convert biogas to generate electricity and heat to supply nearby businesses.”
The new smart grid will feature a 4MW solar photovoltaic array, an 8MW biogas engine and a battery to offer secure and reliable power to around 50 businesses in the industrial district of Marjamäki, south-western Finland.
Under the agreement, Convion will build the two fuel cell co-generation systems and integrate them into the district’s smart grid. The CHP systems will be equipped with Elcogen’s next generation of solid oxide fuel cell stacks and will have the capacity to generate 116kW electrical output.
According to the Finnish Ministry of Economic Affairs and Employment, the Lemene system has the potential to help Finland achieve its national targets and those set by the EU for 2030. /
Wessex Archaeology unearths artefacts on Hornsea project one cable route
/ UK-based archaeology and heritage practice Wessex Archaeology unearthed archaeological remains in Lincolnshire and the surrounding areas during an excavation process for the onshore construction phase of the Hornsea project one offshore wind farm.
Wessex Archaeology carried out archaeological excavations works for the onshore cable route on behalf of the wind farm’s primary developer, Danish power company Ørsted.
Ørsted environment and consents manager Bronagh Byrne said: “Most people wouldn’t associate renewable energy sources with historical artefacts, but it just goes to show the variety of activities needed to build an offshore wind farm.
“We are burying our cables as we understand the sensitivity to the surrounding landscape and the importance this is to local stakeholders and residents.”
The Hornsea project one offshore wind farm will have the capacity to generate enough energy to power over one million homes upon completion. It is expected to begin commercial operations in 2020.
The wind farm will be located 120km off the Yorkshire Coast, while the onshore cable route is slated to run for approximately 40km. The route will be laid between Horseshoe Point, east of Tetney, and a new substation situated in North Killingholme, North Lincolnshire.
Wessex Archaeology personnel and other staff have been working with Ørsted since August 2015. Wessex Archaeology project manager Richard O’Neill said: “Large, linear schemes like this can be challenging; we’ve had seventy people working on the scheme over two years, with some pretty inclement weather at times.
“Work has included excavation of two Iron Age settlement sites in North Killingholme, prehistoric farming activity and a Romano-British settlement in Stallingborough, Romano-British settlement sites in Tetney and Holton-le-Clay, and medieval moated sites in Harborough and South Killingholme.” /
Arenko and GE to build grid-scale energy storage system in UK
