Energy
Building resilience into the future energy network requires novel solutions that do not yet exist.
The energy challenge
The challenge is not in any one area in the energy industry. It’s in joining up disconnected systems and embracing new technology.
A combination of heavily aged infrastructure, a shift to renewable energy sources, increasing energy demand, market volatility, grid connectivity challenges, heavily regulated planning processes and new technologies are creating significant complexity within the energy sector. Understanding uncertainty in energy systems, exploring alternative new systems and predicting behaviour is critical.
These are the perfect set of challenges for advanced modelling and simulation. Through uncertainty quantification, whole system modelling and digital twin technology we’re able to better understand complex energy systems, supporting teams to make design and operational decisions, improving efficiency and innovation.

Conceptual Design Modelling
Understand the energy system’s operational window by quantifying variability in performance across a range of input parameters using physics-based models. Modelling novel systems in this way can help shape their detailed designs as they move towards realisation.
Whole System Modelling
Develop and deploy simulations of complex energy systems to better understand their behaviour. Coupled with high performance compute and design space exploration, engineers can holistically consider performance and gain insight into the impact of changes across the entire system.
Uncertainty Quantification
Predict expected system behaviour of network energy systems through physics-based simulation. Leverage high performance compute and uncertainty quantification to run large-scale simulations to understand typical variability in the system. Better understand the system and improve performance by identifying discrepancies and key sources of uncertainty.
Collaborative Digital Twins
Design and deploy scalable digital twin platforms to improve infrastructure resilience, support the energy transition and address climate adaptation across large scale systems. Immersive 3D visualisation together with real time monitoring and predictive analytics of physical assets support operational decision making, training and maintenance planning.
Graphite Core Modelling
Coupling high-temperature neutronics simulations with structural mechanics to enable the modelling of graphite cores in advanced gas-cooled reactors to improve lifetime, predict performance degradation and support decommission efforts.

Uncertainty Quantification for Nuclear Systems
Uncertainty has a huge impact on the expected performance of systems, particularly in the case of nuclear fusion reactors, where designs are still emergent. Uncertainty quantification identifies key drivers that have a significant impact on the output, highlighting key focus areas, helping to steer development.

Whole system asset modelling
Unaccounted-for-Gas arises predominantly from metering bias rather than physical gas loss and represents a significant operational and financial burden for National Gas Transmissions. A high-fidelity, forward-looking mathematical model was created to rapidly predict expected sensor readings which were used to compare measured values and identify discrepancies.

Common questions about energy systems simulation.
Energy systems are subject to large amounts of uncertainty. Due to a range of factors on both the load and generation, they often don’t perform as expected. Uncertainty quantification can help identify key drivers of system performance, supporting targeted investigations, proactive maintenance and improving performance.
Energy systems often rely on the interplay between several physical domains, for example heat, fluids and phase changes. Tightly coupled physics simulations consider all these domains simultaneously, solving for all parameters at the same time. This process enables more accurate simulations which better model the intricate nature of these systems. The improvement in accuracy reduces uncertainty, providing more realistic estimates of performance and therefore a deeper understanding of the system.
A digital twin utilises 3D visualisation along with real-time monitoring from assets and predictive analytics to support decision making. It enables you to assess performance, make quicker decisions and make decisions to move forward.
For new systems, being able to understand behaviour and the impact of decisions is critical and helps to improve the quality of decisions.
