Siemens Gamesa Launches the World’s Largest Offshore Turbine at 14 MW

The winds of change have never been stronger, especially when it comes to meeting the world’s needs for clean, renewable energy as Siemens Gamesa has launched its new SG 14-222 DD offshore Direct Drive wind turbine with an unprecedented 14-megawatt (MW) capacity – reaching up to 15 MW using the company’s Power Boost function. With a 222-meter diameter rotor, 108-meter long blades, and an astounding 39,000 m2 swept area, the newest Siemens Gamesa wind turbine stands tall in a world currently undergoing an enormous upheaval. “We’ve gone bigger for the better,” states Markus Tacke, CEO of Siemens Gamesa Renewable Energy. “Safely and sustainably providing clean energy for our customers and society-at-large is at the core of all we do. The new SG 14-222 DD is a global product that allows all of us to take giant steps towards protecting and preserving our planet. We ourselves became carbon neutral in late 2019 and are on track towards meeting our long-term ambition of net-zero CO2 emissions by 2050. Our installed fleet of over 100 GW both offshore and onshore abates more than 260 million tons of CO2 emissions annually.” The 14 MW capacity allows one SG 14-222 DD machine able to provide enough energy to power approximately 18,000 average European households every year. Approximately 30 SG 14-222 DD offshore wind turbines could furthermore cover the annual electricity consumption of Bilbao, Spain. “Offshore is in our DNA,” states Andreas Nauen, CEO of the Siemens Gamesa Offshore Business Unit. “Since we helped create the offshore wind industry in 1991, we’ve been determined to safely increase operational performance, minimise technology risks, and create a consistently lower Levelised Cost of Energy. The SG 14-222 DD demonstrates our drive to lead the way in a world powered by clean energy. In fact, just one unit will avoid approx. 1.4 million tons of CO2 emissions compared to coal-fired power generation over the course of its projected 25-year lifetime,” he adds. The 222-meter diameter rotor uses the new Siemens Gamesa B108 blades. As long as almost three Space Shuttles placed end-to-end, each 108-meter long IntegralBlade is cast in one piece using patented Siemens Gamesa blade technologies. Additionally, the turbine’s massive 39,000 m2 swept area is equivalent to approximately 5.5 standard football pitches. It allows the SG 14-222 DD to provide an increase of more than 25 percent in Annual Energy Production compared to the SG 11.0-200 DD offshore wind turbine.

Running fuel cells on bacteria

Researchers in Norway have succeeded in getting bacteria to power a fuel cell. The "fuel" used is wastewater, and the products of the process are purified water droplets and electricity. This is an environmentally-friendly process for the purification of water derived from industrial processes and suchlike. It also generates small amounts of electricity – in practice enough to drive a small fan, a sensor or a light-emitting diode. In the future, the researchers hope to scale up this energy generation to enable the same energy to be used to power the water purification process, which commonly consists of many stages, often involving mechanical and energy-demanding decontamination steps at its outset. Nature's own generator The biological fuel cell is powered by entirely natural processes – with the help of living microorganisms. "In simple terms, this type of fuel cell works because the bacteria consume the waste materials found in the water", explains SINTEF researcher Luis Cesar Colmenares, who is running the project together with his colleague Roman Netzer. "As they eat, the bacteria produce electrons and protons. The voltage that arises between these particles generates energy that we can exploit. Since the waste in the wastewater (organic material) is consumed and thus removed, the water itself becomes purified", he says.

ABB India has developed a solar-powered water pump

ABB India has developed a solar-powered water pump for irrigating crops with rural India facing problems in the supply of electricity and availability of diesel for operating gensets. “ABB solar pump drive starts automatically when there is enough sunshine and the motor connected to it begins to run the pump to draw water. At sunset, the drive turns off the motor and the water flow ceases,” Vinod Raina, senior Vice President (Transformers division) at ABB India, told reporters here. He said that the built-in maximum power point tracking functionality enables the pump to run at maximum power using the available solar energy. He said that switching from use of conventional energy or diesel gensets to solar power can free up as much as 18 per cent of the electricity that can be used for other purposes. “As much as 18 per cent of the total electrical energy generated goes into agriculture. There are nine million diesel pump-sets in India. Even if 50 per cent of these are converted to solar powered pumps, it will save 25 billion litres of diesel per year,” Raina said while claiming that the implementation of the solar pump can improve agricultural productivity to at least two crops a year in most parts of the country. The unreliable electricity supply in rural areas, the ABB official said, resulted not only in wastage of energy but also of water. “Due to the uncertain power supply, pumps are kept switched on waiting for electricity and, often unattended, lead to water being drawn out and wasted,” he said. Raina said that with the government having set a target of deploying 1,00,000 solar pumpsets over the next five years, states like Maharashtra, Rajasthan and Gujarat are key adopters followed closely by Karnataka and Andhra Pradesh.

The Plug into Safety RCD campaign continues to garner coverage in a range of media outlets. Following on from the launch last May, the ESC has continued

We know that to really get a message across to an audience, you can’t just say it once and hope that people remember. You have to repeat it, over a period of time, in different ways, to try and embed the information,”explains Angela Murphy, ESC media manager. “To be really effective, a campaign needs time and if its objective is to help bring about behavioral change, it can take years.” To take advantage of the summer seasonal focus, the Council initially targeted home and gardening publications - both in print and on-line - with a range of electrical safety tips emphasising RCD protection. Among the coverage gained are items in magazines such as Period Living, Traditional Homes and Garden News. Of course, it is also vital that the ESC keeps the industry informed and involved in its activity; and the Council has achieved a spate of coverage in the trade press, particularly with the launch of the Electrician’s tool-kit (see below). Articles and news items have appeared in, to name a few, Professional Electrician, Electrical Digest and Electrical Contracting News. The toolkit is specifically designed to help contractors communicate the benefits of RCD protection to customers. In addition to safety information, it also contains detachable, blank business cards - urging consumers to install RCD protection - which contractors can leave with clients after a house-call. This is just one of the ways in which the Council is supporting industry in encouraging householders to install RCDs and take on board basic safety messages. To supplement this, the Council has also been pursuing coverage in key stakeholder publications, including Fire and Rescue Services magazines and local council websites. “There is no doubt that we have been able to achieve strong media coverage but the life-blood of any campaign is case studies – people's real-life stories," adds Angela. "We have been developing a number of these to use with the Plug into Safety campaign but we are always looking for more. So, if you, a friend or family member, or even a client, have a story to tell about how an RCD saved a life or prevented an injury – or could have, if one had been used – we would love to hear from you.”
