The new frontier of offshore wind power is floating wind turbines. That’s because they can be installed in deep water where wind speeds are consistently higher. The new designs have the floating turbines, that bob and sway with the waves and wind, stabilised with ballast or anchored with chains to the seafloor. Emma Edwards at Oxford University looks at the six major categories of design: Spar, Barge, Tension-leg platform, Semi-submersible, … [Read more...]
Using Generative AI to speed up and improve the Wind Turbine blade design process
Justin Daugherty at NREL describes research there on using generative AI to accelerate and improve the wind turbine blade design process. To keep up with the pace of change in the market (not just customer demands, but policy regulations and technological innovations), the current method uses simplified low-fidelity modelling because it’s quicker to turn around. But it is also less accurate. Researchers are exploring deep-learning models using … [Read more...]
Formula 1’s energy efficiency innovations for road transport are being wasted
Formula 1 racing is infamously emissions intensive. But the pressure to win is a pressure to innovate and raise energy efficiency, supported by an extravagant budget. Maximilian Auffhammer at the Energy Institute at Haas looks at what has been achieved over decades, and what has – and has sadly not – been translated onto our roads. The earliest cars had 4.5L engines that produced 400 horsepower, refuelled during the race. Today’s cars have 1.6L … [Read more...]
Electricity Market Design – creating the stimulus for competitive Offshore Wind within the internal energy market
Ahead of the upcoming discussion in Brussels (September 18, 15:00, Polish Embassy REGISTER HERE) on how to stimulate renewable investment, see below for a reminder of what was discussed at our conference before the summer. This time around, following an open address by Wanda Buk, VP Regulatory Affairs at PGE, PGE Baltica's CEO, Arkadiusz SeksciĹ„ski will be joined by Thor-Sten Vertmann, Electricity Market Design (EMD) expert within Ms Kadri … [Read more...]
Building Materials “Embodied Carbon”: reaching net-zero with low-carbon cement, timber, modular design and more
In this explainer Madeline Weir, Audrey Rempher and Rebecca Esau at RMI first describe how embodied carbon is calculated. They then summarise the strategies being employed to reduce it, including using low-carbon, carbon-neutral, or even carbon-storing materials. New cement formulations are being developed with over 60% less CO2 emissions than the regular kind. Low-carbon mass timber is an alternative building material under development. On the … [Read more...]
Hydropower’s full potential: emulator optimises designs and operations in real time
Hydropower plants are big and expensive. And no two plants are the same, located in different geographies. That makes it very hard to customise and test their design. Contrast that with other clean energy technologies like wind and solar, which are much easier to model, perfect, modularise and then deploy. As Caitlin McDermott-Murphy at NREL explains, it’s why researchers there are creating a hydropower plant emulator that tests designs and how … [Read more...]
“Exascale” computing algorithms can deliver new Wind Turbine designs and on-site power-maximising strategies
Advances in exascale computing algorithms and models for multiscale atmospheric flows are leading to new wind turbine designs and on-site power-maximising strategies previously not possible, explains Brooke Van Zandt at NREL. The models can contain and process two billion grid points, simulating the air flow around turbines in a large wind farm with unprecedented accuracy. Van Zandt describes how the new tools are being used to deal with highly … [Read more...]

Convolutional neural networks: facial recognition AI applied to analysis and design of Advanced Nuclear Reactors
Scientists are looking for new ways to predict how materials survive high temperatures, pressures and corrosion levels, and design new materials that can do so. Temperatures can reach 800 Celsius in parts of solar energy plants and advanced nuclear reactors. Dave Bukey at the Argonne National Laboratory looks at research that uses convolutional neural networks – a type of AI – to uncover patterns in huge data sets. The method is over 2,000 faster … [Read more...]
Study identifies causes of soaring Nuclear plant cost overruns
Why does nuclear power cost so much when the technology has had decades to get it right? MIT’s David Chandler explains how researchers there have identified the main causes of the cost overruns in the U.S. It turns out that building new plants by copying existing designs actually costs more. That’s because site-specific constraints mean problems are being fixed during construction, adding to costs and delays. New types of concrete are being … [Read more...]
AI software to improve Nuclear reactor designs, performance, safety, lifetimes
Nuclear plants have high up-front costs, complex processes occurring all the way down to the molecular level throughout their decades-long lifetimes, and strict safety criteria. Modelling all the parameters and predicting the outcomes has traditionally begun with theory and observation followed by simulations, the results of which are fed back into the next round of theories, and repeated until those results look valid. The quality of the … [Read more...]
