Energy Business Review | Thursday, April 03, 2025

The tanks enhance energy system flexibility and reliability and contribute to the transition to a resilient energy future.

FREMONT, CA: Thermal storage tanks are essential to global energy systems, addressing the imbalance between energy supply and demand. They store surplus thermal energy at low demand or times of high renewable energy generation, which would otherwise go to waste and not be used efficiently to tackle the issue of intermittency. They can be primarily used in conjunction with concentrated solar power plants.

Solar radiation is intermittent, varying throughout the day, and affected by weather conditions. Thermal storage tanks enable CSP plants to store excess heat generated during high solar irradiance periods and utilize it later to generate electricity during periods of low or no sunlight, providing a more reliable and dispatchable renewable energy source. Thermal storage tanks can enhance the efficiency of conventional power plants by enabling them to operate more flexibly. Another promising application of thermal storage tanks is the electrification of heating and cooling systems. 

Thermal storage tanks can be integrated into district heating and cooling systems, where they store excess heat or cold generated by combined heat and power (CHP) plants, industrial processes, or waste heat recovery systems. During periods of low demand, such as at night or in mild weather, excess thermal energy can be stored in these tanks and later used to meet peak demand or provide heating or cooling when the primary energy source is unavailable or insufficient. These plants can operate at their optimal efficiency levels for longer durations, reducing fuel consumption and emissions. 

Thermal storage tanks offer a versatile and efficient solution to the energy sector's challenges, including integrating renewable energy sources, electrifying heating and cooling systems, and optimizing conventional power plants. In conventional power plants, such as those fueled by natural gas or coal, ramping up and down to match fluctuating demand can be inefficient and costly. As countries strive to decarbonize their energy sectors, there is increasing interest in electrifying heating and cooling processes currently reliant on fossil fuels. The intermittency of renewable electricity sources poses a challenge for reliably meeting heating and cooling demand. 

Thermal storage tanks can store excess electricity and use it to provide heating or cooling when needed, increasing the efficiency and reliability of electrified heating and cooling systems. In addition to improving energy system efficiency and reliability, thermal storage tanks can provide grid services such as peak shaving, load leveling, and frequency regulation. By strategically discharging stored thermal energy during periods of peak demand or grid instability, these tanks can alleviate stress on the grid and help integrate higher levels of renewable energy.

Breakthroughs in natural gas storage technologies are transforming the landscape of energy storage and distribution. New developments in underground, compressed, liquefied, and adsorption storage methods enhance both efficiency and sustainability in the natural gas sector. Underground natural gas storage remains the most widely used method for storing natural gas, involving gas injection into porous rock formations, salt caverns, or depleted oil and gas reservoirs. Although this method has been used for a long time, innovations have significantly improved its efficiency and safety. Integrating advanced monitoring systems allows for real-time data collection, helping detect potential leaks and optimize storage processes. Enhanced geological modeling and simulation techniques have also increased storage efficiency by improving the understanding of rock formations and gas flow, maximizing storage capacity, and extending the life of underground storage systems. Compressed natural gas involves storing natural gas at high pressures within specially designed containers. Recent breakthroughs in this field focus on the materials used to construct these storage tanks. Using lightweight, high-strength composite materials such as carbon fiber and fiberglass-reinforced composites has significantly improved storage capacity while reducing the weight of tanks. These innovations make CNG storage systems more efficient and cost-effective. Advances in pipeline technology and compression systems are enhancing the distribution of compressed natural gas, allowing for more efficient and widespread delivery to residential, commercial, and industrial users. Liquefied natural gas (LNG) storage involves cooling natural gas to very low temperatures to convert it into a liquid form, reducing its volume significantly. Innovations in LNG storage include improved cryogenic tank designs and materials that enhance the thermal efficiency of storage systems.

Fremont, CA:  The Engineering Procurement and Construction (EPC) processes play a vital role in executing large-scale infrastructure and industrial projects, such as power plants, refineries, transportation systems, and water treatment facilities. Advanced software solutions like Building Information Modeling (BIM), enable stakeholders to create detailed 3D models that enhance planning, design refinement, and conflict resolution. Recently, several significant trends have surfaced in the EPC sector. Cloud-based project management platforms streamline communication among project teams, suppliers, and contractors, leading to improved coordination and faster decision-making. With climate change becoming a pressing concern, EPC projects now incorporate eco-friendly practices and renewable energy solutions. From integrating solar panels and wind turbines into infrastructure designs to implementing green building techniques and utilizing recycled materials, sustainability is increasingly becoming a core consideration in EPC projects.  Supply chain resilience has arisen as a critical trend in EPC. Many companies are now prioritizing local sourcing, establishing strategic partnerships with reliable vendors, and leveraging digital tools. The adoption of modular construction techniques allows for more significant prefabrication of components, reducing dependency on distant suppliers and mitigating supply chain disruptions. There is a growing trend towards integrated project delivery (IPD) and alternative contracting models. Predictive analytics help optimize resource allocation, improve project forecasting, and enhance project outcomes.  IPD encourages early collaboration among project stakeholders, including owners, architects, engineers, and contractors, fostering a more cohesive and transparent project delivery process. Alternative contracting models such as design-build and public-private partnerships (PPPs) offer greater flexibility, efficiency, and cost certainty than traditional procurement methods. The approaches incentivize innovation, shared risk, and value-driven outcomes, driving higher performance and client satisfaction. The EPC sector is witnessing increased adoption of modularization and offsite construction techniques. Modularization involves fabricating components or modules offsite in controlled factory environments before transporting them to the project site for assembly.  The approach offers numerous benefits, including accelerated project schedules, reduced labor costs, improved quality control, and enhanced safety. Offsite construction minimizes disruptions to local communities and reduces environmental impacts associated with traditional construction methods, making it an attractive option for complex and time-sensitive projects. The digital transformation of EPC projects has led to a greater emphasis on data analytics and predictive maintenance. By harnessing the power of big data, artificial intelligence, and machine learning, EPC firms can optimize asset performance, predict equipment failures, and schedule maintenance activities more effectively.  ...Read more
