Home Energy Storage Market Trends

Industry insights · Feb 20, 2023

In recent years, the home energy storage market has seen significant growth, driven by the increasing popularity of renewable energy sources such as solar power, as well as advancements in battery technology. Home energy storage systems provide a way for homeowners to store excess energy generated by their renewable energy systems and use it later when needed, reducing their reliance on the grid, and lowering their energy bills. In this article, we will examine the latest trends and developments in the home energy storage market, including new products, technologies, and emerging players.

One of the most significant trends in the home energy storage market is the increasing popularity of lithium-ion batteries. Lithium-ion batteries are widely used in smartphones, laptops, and other consumer electronics, and they are also becoming increasingly popular for home energy storage. Lithium-ion batteries offer several advantages over other types of batteries, including high energy density, long lifespan, and low maintenance requirements.

Several companies are now offering home energy storage systems based on lithium-ion batteries, including Tesla, LG Chem, and Enphase Energy. Tesla's Powerwall is one of the most well-known home energy storage products on the market, offering up to 13.5 kWh of storage capacity and a sleek, wall-mounted design. LG Chem's RESU home battery also uses lithium-ion technology and is available in several different sizes, ranging from 3.3 kWh to 9.8 kWh.

Another trend in the home energy storage market is the integration of energy storage systems with home automation and energy management systems. Home automation systems can be used to monitor energy usage and adjust settings to optimize energy efficiency, while energy management systems can be used to control energy storage and distribution. By integrating these systems with home energy storage systems, homeowners can gain greater control over their energy usage and save money on their energy bills.

Several companies are now offering integrated home energy storage and management systems, including FranklinWH, which offers its Franklin Home Power (FHP) system. The FHP system includes aGate, an intelligent home energy management center that integrates solar, battery, grid, and generator power sources and manages them to optimize consistent energy supply, providing rapid backup in case of grid outages; and aPower, a 13.6 kWh AC-coupled battery with a built-in inverter that automatically transfers between DC and AC current. It uses extremely safe LFP cells and can stack up to fifteen aPower batteries per aGate.

In addition to lithium-ion batteries, other types of batteries are also being used for home energy storage. For example, flow batteries, which use liquid electrolytes to store energy, offer several advantages over other types of batteries, including long lifespan, high efficiency, and the ability to scale up easily. Several companies, including Redflow and ViZn Energy, are now offering home energy storage systems based on flow batteries.

Emerging players in the home energy storage market include startups and smaller companies that are developing innovative technologies and business models. For example, Sonnen is a German company that offers a community-based energy storage system called SonnenCommunity, which allows homeowners to share excess energy with other members of their community. Another example is Orison, a US-based startup that offers a plug-and-play home energy storage system that can be installed without any special wiring or installation.

Finally, the cost of home energy storage systems is also becoming more affordable, making them accessible to more homeowners. The cost of lithium-ion batteries has decreased significantly in recent years, and many governments are offering incentives and rebates to encourage homeowners to install renewable energy systems and energy storage systems. For example, in the US, the federal government offers a tax credit of up to 30% for the installation of home energy storage systems.

In conclusion, the home energy storage market is evolving rapidly, driven by advances in battery technology, the integration of energy storage systems with home automation and management systems, and the emergence of new players and business models. As the cost of energy storage systems continues to decrease, and governments are encouraging the development of home energy storage installation, the market will grow at a fast speed.
