Juho Lipponen - CCS incentive policies: lessons and strategies - Presentation...Global CCS Institute
This document discusses incentive policies for carbon capture and storage (CCS). It notes that CCS projects currently have high costs and require incentives to be economically viable. An incentive policy architecture is needed with a long-term framework using different policy tools over time as objectives and the technology evolve. Individual policies should address objectives like emissions reductions, learning, and access to capital markets. "Policy gateways" can help define when policies transition between stages and criteria for the transitions. This approach provides stability while allowing adaptation as understanding of CCS improves.
Ireland faces challenges meeting its 2020 EU targets for reducing greenhouse gas emissions and increasing renewable energy. Continuing on the current baseline projections would require significant investment in wind power and incur high costs. Instead, focusing first on reducing energy consumption and emissions from transport through supply chain management could help meet emission targets at lower cost. Investing in biomass from short rotation forestry to replace peat in existing power stations would further reduce costs while creating rural jobs, compared to installing more wind turbines. With the right strategy emphasizing energy efficiency and biomass over wind, Ireland can comply with EU targets at much lower overall expense.

Camco CRIF presentation public sector 12 oct 2011crifcambs
The document presents a framework for increasing renewable energy deployment in Cambridgeshire. It finds that the county has significant potential for solar, biomass, heat pumps, and wind energy under different scenarios. Deployment could range from a low scenario of 8% to a high scenario of 30% by 2031, closing the carbon gap. This would represent billions of pounds in investment. Key pathways for deployment include public sector, community, and commercial. The public sector could maximize the potential of its assets and policies to attract investment. Communities need funding and guidance. The commercial sector requires a supportive policy framework and opportunities to be clearly identified.
This document discusses the uncertainty in annual energy production (AEP) estimates for wind farms in cold climates due to variability in wind speeds and icing conditions from year to year. It models the annual production of a sample wind power site under normal conditions and finds an 8.6% standard deviation in production. Factoring in icing, continuing production with iced blades could reduce AEP 9% on average with an 11.6% standard deviation, while stopping turbines during icing could reduce AEP 17% on average with a 14.7% standard deviation. The type of operational strategy during icing affects both the estimated production losses and variability in annual production.
The document describes an icing map of Sweden created using a mesoscale weather model. The map shows the average number of icing hours per year from 2000-2011 at a resolution of 50m x 50m grid cells. The map is available online and can help with siting new wind farms by analyzing potential icing conditions and estimated production losses at different locations. It also categorizes areas into 5 icing classes defined by the IEA to aid in site classification for wind energy projects.
This document discusses the use of remote sensing devices (RSDs) in cold climates. It finds that RSDs can reliably measure wind shear, turbulence, and extreme winds. At one Swedish site, a Windcube lidar agreed very well with mast measurements and validated the mast's shear profile across the rotor. The document also finds that low turbulence levels do not necessarily lead to an overestimation of energy as seen in some US sites, and that each site should be evaluated individually to determine if an energy loss adjustment is needed. It concludes that deploying an appropriate RSD along with a reference mast can minimize uncertainty and maximize project value.
This document summarizes research on estimating wind power production losses due to icing. Meteorological models are used to calculate icing loads, which are then related to power losses based on comparisons with observed icing loads and production data. Results from the previous winter show generally good agreement between observed and modeled losses at two sites in Northern Sweden when all condensation types are considered. Forecasting power losses from icing hours ahead using mesoscale model output is also discussed.
Future wind power forecast errors, and associated costs in the Swedish power ...Winterwind
The document analyzes future wind power forecast errors and associated costs in the Swedish power system. It models scenarios with 10 and 30 TWh of wind power installed and examines how forecast errors and resulting imbalance costs are distributed among different actors. Forecast errors are estimated to increase imbalance costs due to higher volumes traded, fewer hours when forecast errors offset each other, and potential congestion between price areas with greater wind power penetration.
This document summarizes research on forecasting production losses at a wind farm in central Sweden due to icing conditions. The researchers used observational turbine data, weather research and forecasting (WRF) model output, and an icing model to develop and validate statistical models for predicting hourly wind farm power output. They found that a combination of WRF parameters and icing model outputs best predicted production losses across the three wind parks. Cross-validation showed these statistical approaches improved upon a simple threshold method. Future work will apply the method to additional sites and evaluate forecasts using predicted winds.
This document summarizes the potential impacts of Ireland's transition to the Integrated Single Electricity Market (I-SEM) on ESB power stations. Key impacts include uncertainty around the new Capacity Revenue Mechanism and how it will value existing versus new generation capacity. There is also risk from changes to how renewable energy will be dispatched and incentives. However, a more liquid forward market and increased renewables also provide opportunities for ESB to develop new technologies and contracts. Overall the I-SEM transition presents both risks and opportunities for ESB as the largest generator.
An investigation was conducted into turbine performance and wind flow modelling under stable atmospheric conditions that are common in the Nordic region. Stable conditions present challenges for wind flow modelling and turbine performance. Complex computational fluid dynamics (CFD) modelling was found to reduce errors in wind flow modelling during stable conditions compared to linear models. Theory and preliminary Nordic data suggest turbine performance is reduced during low turbulence stable conditions, especially at higher wind speeds, though performance recovers in the "knee" of the power curve. More power curve measurement data is needed across the Nordic region to better understand impacts. Site-specific calibration for stable versus unstable conditions may help improve performance estimates.
This document discusses creating an icing climatology using downscaling techniques from a weather modeling project. It examines modeling icing events and ice loads, and comparing modeled results to measurements which sometimes show large differences. Two approaches to the climatology are considered: statistically downscaling long-term low-resolution model runs, or modeling shorter representative periods at high resolution. Both have advantages and drawbacks regarding accuracy and representation of climatological conditions. More research is needed to determine the best approach.

The document describes NCAR's wind forecasting system for Xcel Energy. Key points:
- NCAR operates a probabilistic wind power prediction system for Xcel Energy using ensemble forecasts from its WRF model and an Analog Ensemble technique.
- The system provides day-ahead and short-term wind power forecasts for effective grid integration and energy trading.
- Accurate wind power predictions provide economic benefits of $1.9 million per 1% improvement and reduced 238,136 tons of CO2 emissions in 2011 due to avoided generation.
The Havsnäs Pilot Project had three main goals: 1) to help remove barriers to large scale onshore wind development in northern Sweden by studying nature impacts, project finance, and foundation design; 2) to research technical areas like high hub heights and cold climate effects; and 3) to improve knowledge of wind resource assessment, power performance, and icing impacts. Key findings included that mast spacing affected flow modelling uncertainty, multi-point shear methods best characterized profiles, and remote sensing validated shear above measurement heights. Icing reduced annual yield by an estimated 4.1%.
The document discusses testing and development of de-icing systems for ultrasonic wind sensors used in cold climates. It describes different types of ice formation, including primary ice from rain or snow and secondary ice. Testing methods for wind sensors under icing conditions are outlined, including wind tunnel tests where scale models are subjected to controlled icing. The de-icing system of the Ultrasonic Wind Sensor WMT700 is studied under various laboratory conditions to improve performance in cold weather.
This document summarizes the development and applications of a physical/statistical ice throw trajectory model used to assess risks from ice falling from wind turbine blades. The model takes into account wind characteristics, turbine characteristics, and hub height to produce risk density maps. It has been used to assess ice strike risks to infrastructure like roads, power lines, and snowmobile tracks at several sites. Initial validation efforts by comparing modeled throw distances and impact locations to on-site observations show promising results. The model allows more confident quantification and mitigation of public safety and infrastructure risks from ice throw.
The document presents a new differential boundary layer model for the wind turbine icing code TURBICETM. The model solves the differential boundary layer equations using Keller's box method and includes features like grid scaling, a zero-equation turbulence model, and transition criteria. Initial test results on flat plates and airfoils show improved heat transfer predictions compared to the current integral method. Future work includes further model refinement, implementing separation bubble simulation, testing roughness and transition models, and integrating the boundary layer model into TURBICETM.
This document provides an overview of Triventus Consulting, a European wind power consulting firm. It discusses trends in the financing of wind power projects, particularly the increasing difficulty of obtaining financing in Europe. Specific challenges for developing wind projects in Nordic countries like Norway and Sweden are also examined, such as cold climates reducing production and increasing costs. The document emphasizes that only top-quality projects with strong cash flows, credible management, and a long-term commitment will be able to secure necessary financing.
The OWI-Lab provides a large climate chamber for extreme temperature testing and validation of wind turbine components. The climate chamber can test components up to 150 tons in a temperature range of -60°C to +60°C to improve reliability and reduce maintenance costs. Temperature testing helps validate designs and verify performance under cold and hot conditions.
Indirect detection of ice on wind turbine blades can be achieved by monitoring changes in turbine behavior compared to historical baseline data. Five statistical process control methods were tested that calculate the distance between current and baseline measurements to detect icing. Detection accuracy was highest around 50-80% of rated wind speed and could reach 90% in simulations, but real data testing produced some false alarms. The methods provide a simple ice warning signal without additional sensors by analyzing multiple turbine variables simultaneously.
This document summarizes ice-induced vibration measurements on MW-scale wind turbines. It presents two case studies from wind farms in Canada and Finland that experienced icing events: (1) A glaze icing event in Canada that resulted in around 5mm of ice accumulation and a 1.5 hour production loss; (2) A rime icing event in Canada that accumulated 15-20cm of ice on the blades. Instrumentation and data from both sites are described, showing increased vibrations and loads on the turbines when icing occurred. The goal is to better understand how icing affects turbine performance and lifetime through increased fatigue loads.
The document discusses anti-icing and de-icing coating technologies being researched at Fraunhofer IFAM. It summarizes their ice testing facilities and capabilities. It then outlines various active, passive and electrically heated coating concepts being developed, including hydrophobic, biomimetic and nanostructured approaches. Finally, it provides examples of coatings tested on aircraft components and concludes with an acknowledgement of funding sources.
The document discusses the development of customized data loggers for wind turbines in remote Arctic locations. It notes the unique environmental challenges, including rapid temperature fluctuations, high humidity, melting snow and ice damage. It outlines the development of open source loggers over three revisions to optimize for power consumption, reliability, ease of use and harsh environments. Future plans include further field testing and creating a fourth revision with wireless sensors, remote updates and extended battery life.
This document presents a numerical model to simultaneously predict airflow and ice accretion using large eddy simulation (LES) and Lagrangian particle tracking (LPT). The model aims to efficiently and flexibly model ice shape based on the impacting droplets freezing instantly. Validation cases are run to test the model sensitivity by varying grid resolution and other parameters. Sample results show ice shapes formed on an airfoil for different test cases. Future work is proposed to model additional icing regimes and combine the model with other existing tools.
This document summarizes statistics on cold climate wind power production in Finland. It finds that average monthly production was lower than estimates from the Finnish Wind Atlas, especially in winter months, likely due to blade icing and other cold weather effects. The estimated production losses from icing were also smaller than differences between real and estimated production, indicating other technical factors contributed. Further analysis is needed of both production statistics and the accuracy of atlases in estimating cold climate wind power production.
This document summarizes a study comparing mesoscale models for modeling icing climate. It finds that while the major models (AROME, COAMPS, WRF) capture overall meteorological conditions similarly, they show differences in key variables like temperature near 0°C and hours of active icing. Sensitivity tests show the modeled icing load depends on the model, initialization data, microphysics scheme, and planetary boundary layer parameterization used. No single model or setup emerges as definitively best, but model timing of icing events compares well to observations.
The document summarizes the TURBICE model, a two-dimensional ice accretion simulation program developed by VTT to simulate ice buildup on wind turbine blades. It describes how TURBICE uses panel methods and Lagrangian droplet tracking to simulate ice formation. Further development is underway, including a new object-oriented Python interface to improve usability and enable coupling with other simulation programs for multi-physics analyses. The new interface will allow orchestrating standalone programs through data exchange or wrapping source codes as Python modules.
Finnish researchers were already investigating the possibility of de-icing wind turbines in the early 1990’s. But it wasn’t until the beginning of the new millennium that the first de-icing systems became commercially available. The expansion of wind energy in cold climates and icing conditions since the first Winterwind conference in 2008 has been extraordinary. Back then, the estimated total installed annual wind power capacity in cold locations was approximately 1 300 MW. Estimates for 2012 are closer to 5 000 MW annually. This progress could not have been possible without the tireless work of researchers and engineers worldwide. Winterwind is a forum for these researchers and industry participants to find new business partners and discuss the latest technological innovations. Each year, the Winterwind conference attracts the absolute expertise in the field.
More Than A Yearly Event
Our conviction is that sharing experiences drives development. From this perspective, we want to be more than a yearly event.

It then outlines 7 research projects conducted by the Canadian Wind Energy Strategy Network focusing on developing ice-free anemometers, evaluating wind turbine materials, modeling ice accretion, investigating icing impacts in wind tunnels, forecasting icing events, monitoring icing conditions, and mapping icing events across Canada at high resolution. The research involves universities, government agencies, and wind industry partners.
Comparison of visibility observations at a meteorological tower to cloud base...Winterwind
The document examines whether visibility and temperature can be used as a surrogate for detecting icing occurrences by comparing direct icing observations to visibility and temperature measurements. Visibility and temperature were measured at a tower in Puijo since 2005, while direct icing observations were only available for partial seasons from 2009-2012. The author analyzes a small number of cases to compare when visibility is poor (<200m) and temperatures are below freezing (<0°C) to when icing is directly observed, finding visibility and temperature can strongly indicate in-cloud icing. However, more cases need to be analyzed and other icing phenomena need to be considered.

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
What is an RPA CoE? Session 2 – CoE RolesDianaGray10
In this session, we will review the players involved in the CoE and how each role impacts opportunities.
Topics covered:
• What roles are essential?
• What place in the automation journey does each role play?
Speaker:
Chris Bolin, Senior Intelligent Automation Architect Anika Systems
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.

High performance Serverless Java on AWS- GoTo Amsterdam 2024Vadym Kazulkin
Java is for many years one of the most popular programming languages, but it used to have hard times in the Serverless community. Java is known for its high cold start times and high memory footprint, comparing to other programming languages like Node.js and Python. In this talk I'll look at the general best practices and techniques we can use to decrease memory consumption, cold start times for Java Serverless development on AWS including GraalVM (Native Image) and AWS own offering SnapStart based on Firecracker microVM snapshot and restore and CRaC (Coordinated Restore at Checkpoint) runtime hooks. I'll also provide a lot of benchmarking on Lambda functions trying out various deployment package sizes, Lambda memory settings, Java compilation options and HTTP (a)synchronous clients and measure their impact on cold and warm start times.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
