By 2050, solar and wind will represent 69% of grid-connected power generation, according to the DNV Energy Transition Outlook report. As a result, connectivity, storage and demand-response will be critical assets in the decarbonized power system.
This renewables-powered electrification of the world is driving the explosive growth for energy storage, which includes mobile energy storage for transportation alternatives and stationary energy storage for grid-scale, commercial, industrial, and residential applications.
As the demand for stationary energy storage will continue to grow, the market needs reliable, sustainable and affordable technologies to ensure the flow of electricity is uninterrupted.
The stationary energy storage market is predicted to grow at a compounded annual growth rate (CAGR) of 41% through 2030.
Supplying this market are battery energy storage technologies, which ensure that adequate levels of electrical power are always available, even during spikes in demand or when supply is intermittent. In fact, battery energy storage sales are at an all-time high and continuing to grow.
IEA’s World Energy Investment 2022 report states that investment in battery energy storage is currently experiencing the biggest momentum in the power sector, with capital spending expected to nearly triple in just two years. The majority of the growth is occurring in grid-scale utility deployment, which currently represents more than 70% of total spending.
The world is rapidly moving to renewable sources of energy, especially solar and wind power. But when the sun doesn’t shine and the wind doesn’t blow, the need for a steady and reliable form of energy remains.
To provide power during those times when renewable energy supplies are low, the market is seeking highly-reliable battery energy storage systems (BESS) to meet their energy needs. Stationary energy storage solutions help balance supply and demand requirements by capturing the electricity generated from renewables, and then safely discharging it when needed. This stabilizes the grid and reduces the risk of unexpected outages.
Thanks to breakthrough materials science research at Stanford University, the stationary energy storage market is undergoing a dramatic transformation—one that involves taking a proven technology that has been used in space for more than three decades—and repurposing it to create a storage technology that can be used on Earth.
Nickel-hydrogen electrochemistry, given its durability and reliability, was the battery technology of choice by NASA. It has been used in extreme conditions during numerous space mission applications, including the Hubble Space Telescope and the International Space Station.
Nickel–hydrogen battery technology offers many compelling advantages over other technologies.
It is maintenance-free, with minimal OPEX. There is no need for augmentation due to minimal degradation.
It has a proven, 30-year lifespan, based on up to 3 cycles per day and 30,000 total cycles.
It ensures power is available, anytime and anywhere, to ensure uninterrupted supply.
The nickel-hydrogen batteries are 99% recyclable.
It accommodates multiple use cases per day; and since it can cycle multiple times, several use cases can be combined daily.
It has no risk of fire or thermal runaway, with no need for HVAC or fire suppression systems.

Schlumberger Stationary Energy Storage Solutions offers front-of-the-meter (FTM) and behind-the-meter (BTM) customers the best long-duration battery energy storage system (BESS), accelerating their journey to achieve net zero.
Our international footprint, together with best in class technology and talent, ideally positions us to scale up EnerVenue’s nickel hydrogen technology in international markets, reinforcing our focus on sustainability and energy transition.
The EnerVenue batteries can cycle multiple times a day, operate in ambient temperatures from -10°C to 45°C—for a 30-year+ lifespan, with around 30,000 cycles, without degradation; and at charge and discharge rates ranging from C/2 to C/10+. Storage duration sweet spot is between 2 and 12 hours.
The EnerStation battery system is comprised of three strings of 153 modules, connected in parallel. Each module includes a set of 4 battery cells, which slide into a rack. This design allows each EnerStation to operate in the 675-1,500 volts DC range, with a total capacity of 440 kWh. After efficiency losses such as fans and the battery management system, the total usable capacity is 356 kWh.
Each battery system is made up of many individual cells packaged into a container, housing a battery management system. This simple compact design allows easy shipment to the deployment location and simple installation on arrival, saving time and expense in setting up.
