New Guidance on Electrical Transmission Poles Offered in Updated ASCE Standard 48
Reston, Va. – Providing a uniform basis for the design, detailing, fabrication, testing, assembly, and erection of steel tubular structures for electrical transmission poles, this updated standard, Design of Steel Transmission Pole Structures (ASCE/SEI 48-19), applies to cold-formed single- and multipole tubular steel structures that support overhead transmission lines. The design parameters are applicable to guyed and self-supporting structures using a variety of foundations, including concrete...
Wärtsilä gas engines to burn 100% hydrogen
The technology group Wärtsilä is developing the combustion process in its gas engines to enable them to burn 100% hydrogen fuel.Wärtsilä has researched hydrogen as a fuel for 20 years, and has tested its engines with blends of up to 60% hydrogen and 40% natural gas. This development is part of the company’s strategy to future-proof its engine technology in line with the global trend towards decarbonisation of the energy and marine markets. In addition to hydrogen, other potential renewable fuels...

The 18-month study, by Arizona-based Electric Applications Inc (EAI), is one of a range of innovation projects backed this year by the global research group, the Consortium for Battery Innovation (CBI). It will take an in...
Growing Demand for Greasezilla System as FOG Separation Technology Expands into New Vertical and International Markets
LANSING, W.Va. – May 4, 2020 – Downey Ridge Environmental Company, developer of Greasezilla™, reports its installed base is expanding beyond its traditional wastewater treatment and grease trap waste hauling sectors and into the biodiesel production, anaerobic digestion, food processing and water reclamation industries. As the leading clean technology in commercial Fats, Oil and Grease (FOG) separation, the Greasezilla hydronic thermal separation system is increasingly becoming a “front-end” pro...
3D-printed concrete to help build offshore wind energy infrastructure
Illustration of a 3D-printed concrete suction pile anchor for connecting floating wind turbines to the seabed via mooring lines. (Credit: RCAM Technologies) WEST LAFAYETTE, Ind. — Wind off the coasts of the U.S. could be used to generate more than double the combined electricity capacity of all the nation’s electric power plants, reports have suggested. But building wind turbines offshore is expensive, requiring parts to be shipped at least 30 miles away from a coast. Purdue Univer...
Wärtsilä is delivering a 70MW energy storage system in California to optimise renewable energy system performance and maximise ROI
The technology group Wärtsilä is finalising a 70MW energy storage and energy management system project in the California Independent System Operator (CAISO) energy market. The energy storage system will be paired with Wärtsilä GEMS platform to maximise system efficiencies and will add renewable power to the grid at times when it otherwise wouldn’t be available. The order was booked by Wärtsilä in late 2019 and the project will be finalised in mid-2020. Wärtsilä GEMS advanced software platform...
4Subsea Installs IoT Sensors on Floating Turbine Zefyros to Prove Cost Reduction Potential with Digital Twin
4Subsea has installed advanced, retrofit sensors on floating turbine Zefyros (previously Hywind Demo) to prove cost reduction potential with a Digital Twin. A few hours after mobilisation on April 20th, the autonomous sensors started streaming motion and load data to 4insight.io from Unitech’s wind turbine off the west coast of Norway. The project aims to prove significant cost reduction potential in offshore wind by using a Digital Twin of the substructure to measure actual loads and fatigue on...
