At our production center in Pfungen, near Winterthur and Zurich, a skilled team of engineers and specialists manufactures high-tech equipment. Helium liquefaction and refrigeration plants produce cryogenic temperatures by liquefying the coldest gas on earth.
These plants use a variety of complex processes and machinery to cool helium gas to its liquid form, which is then used in a range of scientific and industrial applications, including accelerators like LHC, XFEL or MRI machines and semiconductor manufacturing.
They include the helium refrigerator capable of delivering helium in the required form (liquid, supercritical...) not only at 4.5 K but also at the required intermediate temperatures (80 K shielding...), as well as the fluid storage and distribution system, and the purification systems if required
As a key enabler for low cost solar power, the idea of using inflatable heliostats for large central receiver solar thermal powerplants was proposed in the foundational U.S. patent 5,404,868.

The vanadium redox battery (VRB), also known as the vanadium flow battery (VFB) or vanadium redox flow battery (VRFB), is a type of rechargeable flow battery. It employs vanadium ions as charge carriers.
Vanadium redox flow batteries (VRFBs) represent a revolutionary step forward in energy storage technology. Offering unmatched durability, scalability, and safety, these batteries are a key solution for renewable energy integration and long-duration energy storage. VRFBs are a type of rechargeable battery that stores energy in liquid electrolytes.
Other useful properties of vanadium flow batteries are their fast response to changing loads and their overload capacities. They can achieve a response time of under half a millisecond for a 100% load change, and allow overloads of as much as 400% for 10 seconds. Response time is limited mostly by the electrical equipment.
A vanadium / cerium flow battery has also been proposed . VRBs achieve a specific energy of about 20 Wh/kg (72 kJ/kg) of electrolyte. Precipitation inhibitors can increase the density to about 35 Wh/kg (126 kJ/kg), with higher densities possible by controlling the electrolyte temperature.
Flow batteries have a storied history that dates back to the 1970s when researchers began experimenting with liquid-based energy storage solutions. The development of the Vanadium Redox Flow Battery (VRFB) by Australian scientists marked a significant milestone, laying the foundation for much of the current technology in use today.
Flow battery design can be further classified into full flow, semi-flow, and membraneless. The fundamental difference between conventional and flow batteries is that energy is stored in the electrode material in conventional batteries, while in flow batteries it is stored in the electrolyte.
Scalability: Flow batteries are more easily scalable than lithium-ion batteries. The energy storage capacity of a flow battery can be increased simply by adding larger tanks to store more electrolyte, while scaling lithium-ion batteries requires more complex and expensive infrastructure.
Energy production and distribution in the electrochemical energy storage technologies, Flow batteries, commonly known as Redox Flow Batteries (RFBs) are major contenders.
Some key use cases include: Grid Energy Storage: Flow batteries can store excess energy generated by renewable sources during peak production times and release it when demand is high. Microgrids: In remote areas, flow batteries can provide reliable backup power and support local renewable energy systems.
The primary innovation in flow batteries is their ability to store large amounts of energy for long periods, making them an ideal candidate for large-scale energy storage applications, especially in the context of renewable energy.
Energy storage is the main differing aspect separating flow batteries and conventional batteries. Flow batteries store energy in a liquid form (electrolyte) compared to being stored in an electrode in conventional batteries. Due to the energy being stored as electrolyte liquid it is easy to increase capacity through adding more fluid to the tank.
Flow batteries represent a versatile and sustainable solution for large-scale energy storage challenges. Their ability to store renewable energy efficiently, combined with their durability and safety, positions them as a key player in the transition to a greener energy future.
Scalability: One of the standout features of flow batteries is their inherent scalability. The energy storage capacity of a flow battery can be easily increased by adding larger tanks to store more electrolyte.
Electrolytes: The two most important elements of a flow battery are the positive and negative electrolytes, typically stored in separate external tanks. These electrolytes are usually in liquid form and contain ions that facilitate the battery's energy conversion process.
Concentrated Photovoltaics (CPV) are at the forefront of this transition due to their high efficiency and clean energy generation capabilities. However, CPV cell stability and reliability are compromised by high operating temperatures, necessitating effective cooling solutions.
However, the implementation of this solution requires a suitable energy storage method. Liquid Air Energy Storage (LAES) has emerged as a promising energy storage method due to its advantages of large-scale, long-duration energy storage, cleanliness, low carbon emissions, safety, and long lifespan.
While solar cooling can be provided without any storage capacity, our design is intended to make use of the high levels of sunlight during the peak irradiation time during the day in order to provide cooling during the subsequent period of peak cooling demand. Therefore, our design does utilize a method for storing energy for cooling as needed.
Therefore, our design does utilize a method for storing energy for cooling as needed. The combined air conditioning and thermal storage system is intended as a technology to increase the effectiveness of solar photovoltaic energy use.
Ebrahimi et al. introduced an LAES system incorporating solar thermal energy, LNG regasification, gas turbine power generation, and the Kalina cycle, with an electrical storage efficiency of 57.62 % and an energy storage efficiency of 79.87 %.
Korean scientists have designed a liquid air energy storage (LAES) technology that reportedly overcomes the major limitation of LAES systems - their relatively low round-trip efficiency.
In decoupled liquid air energy storage, the energy storage system is designed to operate independently and control the storage and release of energy without the need to connect to or rely on the power system directly.

He predicts that in the next 5 to 10 years, the installed capacity of vanadium flow batteries could exceed that of lithium-ion batteries. This announcement aligns with the recent formation of the Central Enterprise New Energy Storage Innovation Consortium.
Vanadium Flow Batteries (VFBs) are a stationary energy storage technology, that can play a pivotal role in the integration of renewable sources into the electrical grid, thanks to unique advantages like power and energy independent sizing, no risk of explosion or fire and extremely long operating life.
According to an industry white paper, China's vanadium battery industry will reach a cumulative installed capacity of 2.3 GW by 2025 and 4.5 GW by 2030. The total market size of the industry is projected to be 24 GW with a total market size of 40.5 billion yuan ($5.62 billion).
Currently, besides the demonstration projects of the two major power grids, the National Energy Group and several provinces including Jilin, Hebei, Sichuan, Jiangsu, and Shenzhen have issued vanadium flow battery tender projects. Vanitec is the only global vanadium organisation.
Alternatively, vanadium can be sold to the iron and steel industry which sums up 80% of the whole vanadium demand, in a market trend where the production of vanadium is constantly increasing, from 35,000 t in 1994 to almost 90,000 t in 2020 .
The 400-megawatt (MW) vanadium flow energy storage power station is expected to have a total investment of 680 million yuan ($94.46 million). A contract for its construction was signed on September 28 in Jishou, Hunan Province, and it is projected to be completed and connected to the grid at full capacity by the end of June 2023.
What Type of Water Should You Use for Lead Acid Car Battery Maintenance?Distilled Water: Using distilled water is essential for lead acid car batteries. Distilled water undergoes a purification process that removes minerals and impurities.
When filling a lead acid battery, tap water should not be used. Tap water contains minerals and micro particulates that are harmful to batteries, more so in water softened by water softeners that contain chlorides. Filling your batteries using distilled water is a much smarter investment.
If you have a flooded lead acid battery then a battery watering system or battery watering gun will allow you to quickly and safely water your battery. WHEN TO WATER A LEAD ACID BATTERY? Flooded lead acid batteries contain a liquid called electrolyte which is a mixture of sulfuric acid and water.
One of the most important factors to consider when it comes to lead acid battery maintenance is the water level. Keeping the battery hydrated means that you will have to water your battery regularly. Putting too much water in the cells reduces capacity and conversely not watering them often enough does internal damage both of which are undesirable.
Adding water to a lead-acid battery is a straightforward process, but it must be done carefully to avoid damage or injury. Follow these steps to add water to your battery safely: Before starting, make sure to wear safety goggles and gloves to protect yourself from the corrosive battery acid.
How often do you need to add water to a lead acid battery will depend on how often it's used. A marine or golf cart battery that is only used on the weekends may only require watering once a month. A forklift that is used every day, may need to have its battery watered once a week.
During normal operation, batteries only consume water – not acid. And if you add acid, you'll disrupt the electrolyte's balance. Another reason not to add acid is that it's simply dangerous. So when you observe the electrolyte to be lower than needed, only fill the battery with water.
To address this issue, a liquid cooling system with additional cooling channels can be used to keep the lithium-ion battery packs within the proper temperature range.
A new type of rechargeable alkali metal-chlorine battery developed at Stanford holds six times more electricity than the commercially available rechargeable lithium ion batteries commonly used today.
Chlorine-based electrochemical energy storage is a promising candidate for sustainable battery technology. The anionic redox reaction of Cl0/−1 is of interest due to its superior redox potential (1.36 V vs. standard hydrogen electrode ), capacity (756 mAh g −1), high power, and low cost.
As an ancient battery system born ≈140 years ago, chlorine (Cl)–based batteries have been actively revisited in recent years, because of their impressive electrochemical performance with the low–cost and sustainable features, making them highly attractive candidates for energy storage applications.
The chlorine flow battery can meet the stringent price and reliability target for stationary energy storage with the inherently low-cost active materials (~$5/kWh) and the highly reversible Cl 2 /Cl − redox reaction. Integrating renewable energy, such as solar and wind power, is essential to reducing carbon emissions for sustainable development.
The solid state chlorine-ion batteries have improved the safety of the battery. Not only that, solid-state CIBs generally have a higher energy density because they do not require liquid electrolytes, allowing for greater energy storage efficiency. This allows solid-state CIBs to store more energy in the same volume.
Furthermore, chloride ion batteries (CIBs) based on chloride ions (Cl −) shuttling have raised much attention because of the abundant sources, high energy density, and large potential in large-scale energy storage applications, . As a theoretical prediction, AlCl 3 vs. Mg battery can deliver a specific energy density of 475 mA h g −1.
