Birmingham City Council appoints four firms to transport and infrastructure framework.

Birmingham City Council appoints four firms to transport and infrastructure framework. Birmingham City Council has appointed AtkinsRéalis, Jacobs, Mott MacDonald and Pell Frischmann Consultants to its Transportation and Infrastructure Professional Services Framework, a major consultancy agreement expected to support highways and infrastructure projects across the city and wider Midlands region over the next eight years. The framework, valued at up to £400m excluding VAT, will provide multidisciplinary design and advisory services covering areas including highways engineering, transport planning, drainage, air quality, structural engineering, traffic systems and wider infrastructure consultancy. Approximately £240m of the projected spending is expected to relate directly to Birmingham City Council projects, with the remaining work potentially commissioned by other public bodies across the East and West Midlands through access agreements. The council said the framework has been established under the Procurement Act 2023 as an "open model", allowing suppliers to be refreshed or added during the life of the agreement rather than fixing membership for the entire contract period. The framework is scheduled to run from 2026 until 2034 under NEC4 contract terms. According to procurement documents, the framework is intended to cover a broad range of technical and professional services associated with transport and civil infrastructure delivery. These include engineering design, project management, road safety audits, sustainability and environmental advice, urban design, drainage services, street lighting, archaeology and air quality management. Eight organisations are understood to have bid for places on the framework before the final four firms were selected. Birmingham City Council also specified that at least 20% of services delivered through the framework must be subcontracted to small and medium-sized enterprises. The appointments come as Birmingham continues to progress a series of transport, regeneration and public realm schemes linked to wider infrastructure investment and urban development plans across the city. Previous frameworks have supported projects ranging from highways upgrades and Metro extensions to bridge maintenance and transport strategy work.

Innovative Amsterdam terminal set to transform hydrogen and CO2 supply chains.

Innovative Amsterdam terminal set to transform hydrogen and CO2 supply chains. Key points. * EcoLog is developing a new terminal in Amsterdam for liquefied hydrogen and CO2. * The terminal will have a capacity of 200,000 tonnes of hydrogen and 1.8 million tonnes of CO2 per year. * Innovative integration of hydrogen and CO2 cycles aims to boost overall efficiency. * Collaborations with major partners enhance the project's strategic implementation. EcoLog is embarking on an ambitious project to establish a terminal in Amsterdam's port dedicated to the import of liquefied hydrogen and the export of liquefied CO2, aiming to create a robust supply chain for hydrogen in north-western Europe. This initiative is part of a broader strategy to facilitate decarbonization in industries that are challenging to electrify, such as steel manufacturing, heavy mobility, maritime transport, and data centers. The Amsterdam terminal's first phase is projected to have a capacity of 200,000 tonnes of liquefied hydrogen (LH2) and 1.8 million tonnes of liquefied carbon dioxide (LCO2) annually, with the potential for expansion to 600,000 tonnes of hydrogen and 4.25 million tonnes of CO2. The operational goals target high-demand regions like Germany and the Netherlands, emphasizing the importance of this infrastructure in the wider context of the energy transition. To realize this project, EcoLog has awarded the contract for Front-End Engineering Design (FEED) to KBR, a US-based engineering firm, and appointed Mott MacDonald, a British consultancy, for technical supervision. The FEED contract is expected to be completed within the year, laying the groundwork for the terminal's construction. A distinctive feature of the project is the integration of the hydrogen and CO2 cycles. The cooling produced during the regasification of liquefied hydrogen will be harnessed to aid in the liquefaction of CO2, thus significantly enhancing the plant's overall efficiency. This innovative approach highlights EcoLog's commitment to sustainability and operational efficiency. In addition to this terminal, EcoLog has recently signed several agreements with industrial and technological partners to bolster its capabilities. Notably, a partnership with Gas and Heat focuses on developing LH2 storage and management systems for their vessels. Moreover, collaborations with Japanese companies such as Ebara Corporation and Kobe Steel directly link to the new terminal's development. Overall, this project signifies a strategic effort to build a commercial supply chain for liquefied hydrogen, an essential component in the ongoing global transition towards cleaner energy sources. By playing a crucial role in facilitating hydrogen's deployment, EcoLog not only aims to meet the energy demands of the future but also to contribute significantly to the reduction of carbon emissions in critical industrial sectors.
