Methane-laden waters of Ruanda’s Lake Kivu, if left untapped, can accumulate to a gas bubble and trigger an explosion that poses a deadly risk for more than 2 million people living along the lake’s shores. The U.S. energy services firm ContourGlobal assessed this risk before starting to extract methane from the lake for power generation.
Siemens has commissioned the second block of the 500 MW high-voltage direct-current (HVDC) back-to-back link in Bheramara, Bangladesh, linking the country’s power grid with the one of its bigger neigbour India. With block 1 & 2 operating in parallel the Bheramara HVDC link can transport up to 1000 MW of electricity, helping to stabilize electricity supply in the region.
Siemens has launched a Frequency Stabilizer SVC Plus FS that combines static-var-compensation with supercapacitors. Capable to compensate voltage and frequency fluctuations, the device can feeds reactive power into the grid in less than 50 milliseconds. At the same time, the up to 200 megawatts of electric power stored in the supercapacitors can be transferred to the grid at full load.
Siemens and the South Korean manufacturer Iljin Electric have teamed up to develop an SF6-free gas-insulated switchgear (GIS)for the 170 kilovolt (kV) level, building on a similar Siemens application for up to 145 kV. The new GIS will use treated air, known as "Clean Air", instead of sulfur hexafluoride (SF6) as the insulating medium.
Dry and hybrid cooling is gaining ground in the U.S. power generation market, although over 61% of thermoelectric plants still use recirulating systems with cooling water. According to EIA figures, the 83 U.S. power plants that operate dry and hybrid cooling systems support about 20 gigawatts (GW) of steam-generating capacity.
The role of the grid is experiencing a pivotal change, amid rising requirements for grid balancing and renewable integration. Smart grids are forecasted to represent two-thirds of global net electricity by 2050. By then, an estimated $548 billion will be invested in battery capacity, says Seb Henbest at Bloomberg New Energy Finance (BNEF).
ABB, working through local distributor Consorcio AMESA, has won a $6.4 million contract to install 62 units of Elastimold switchgear along Paseo de la Reforma — Mexico City’s iconic boulevard. The rollout is part of a $150 million Comisión Federal de Electricidad project to upgrade stability of power supply to data-intensive banks, government offices and corporate headquarters that line the street.
Bentley Systems and Siemens have decided to strengthen their strategic alliance by increasing the innovation investment program from the initial €50 million funding to €100 million. Making use of Siemens’ technical expertise and project management tools the two partner aim to create a full Digital Twin for the engineering and construction world.
Agile, more efficient testing and product development for the marine, oil & gas and new energy sector will be facilitated at Wärtsilä’s new technology hub on Vaskiluoto island, near the Finish city of Vaasa. Wärtsilä will invest €83 million in modern testing and production technology for the hub, while total investment will amount to over €200 million.
Smart electrically-driven heating is a “valuable field in which to invest”, Delta-ee research finds, pointing at the substantial installed base of electrically-driven heating – 30 million units across Europe. In the UK, new business models are emerging providing heat-as-a-service, with the customer avoiding the need for buying fuel and appliances by simply buying the heat, and comfort that comes with it.
Cold energy, set free when LNG gets regasified through heat exchangers, can be utilized and monetised in different sectors, including the production of special gases through cryogenic air separation, desalination and also in the power sector. Hereby, the cold energy gets reused for inlet cooling of gas turbines.
Siemens has successfully 3D-printed and engine-tested a dry low emission (DLE) pre-mixer for its SGT-A05 aeroderivative gas turbine. From concept to engine test, the development took only seven months, which is impressive considering this component requires very tight tolerances and works in high load and temperature.
Dispatchable power generation capacity is shifting from flexible gas gensets to wind and solar technologies paired with energy storage. Excellent solar resources in the U.S. state of Arizona make First Solar confident that its 65MW solar farm and a 50MW/135MWh battery storage facility will outcompete gas peaking plants in terms of supplying electricity into the evening peak.
Eager to gain proprietary turbine technology, State Power Investment Corporation (SPIC) of China has signed a Memorandum of Understanding (MoU) with Ansaldo Energia this week to achieve mutually beneficial results in the heavy duty gas turbine area. The accord comes just weeks after Siemens and SPIC struck a technology cooperation in early June to enhance their heavy duty gas turbine programme.
