A reddit focused on the storage of energy for later use. This includes things like batteries, capacitors, super-capacitors, flywheels, air compression, oil compression, mechanical compression, fuel tanks, pumped hydro, thermal storage, electrical storage, chemical storage, thermal storage, etc., but also broadens out to utilizing 'more-traditional' energy mediums... where their focus is on their energy storage potential for later use, including even using 'the grid' for storage.

The Energy Storage Reddit

Energy storage is accomplished by devices or physical media that store energy to perform useful operation at a later time. A device that stores energy is sometimes called an accumulator.

All forms of energy are either potential energy (e.g. Chemical, gravitational, electrical energy, etc.) or kinetic energy (e.g. thermal energy). A wind-up clock stores potential energy (in this case mechanical, in the spring tension), a battery stores readily convertible chemical energy to operate a mobile phone, and a hydroelectric dam stores energy in a reservoir as gravitational potential energy. Ice storage tanks store ice (thermal energy) at night to meet peak demand for cooling. Fossil fuels such as coal and gasoline store ancient energy derived from sunlight by organisms that later died, became buried and over time were then converted into these fuels. Even food (which is made by the same process as fossil fuels) is a form of energy stored in chemical form.

Despite the overall growth of the new energy industry, SolarEdge experienced a revenue decline in 2023, attributed to the industry-wide destocking process.

Reports indicate that market demand in Europe and the U.S. was disrupted by high interest rates and policy uncertainties. In 2023, SolarEdge's revenue from its inverter, optimizer, and backup battery businesses reached $1.37 billion, $900 million, and $380 million respectively. This represented a 20.8% increase, a 20.5% decline, and an 11.8% decrease from the previous year. Furthermore, sales figures stood at 1.013 million sets, 17.4 million sets, and 744 MWh, marking declines of 0.8%, 26.6%, and 2.2% respectively compared to the previous year. The unit prices were recorded at USD 1,356 per set, USD 52 per set, and USD 0.51 per kWh respectively.

The substantial decline in optimizer sales can be attributed to the superiority of micro-inverter solutions over optimizer and string solutions in meeting the stringent MLPE requirements set forth by the NEC for rapid shutdown functionality.

In 2023, the company's photovoltaic business revenue in the European and U.S. markets amounted to $1.81 billion and $760 million, respectively. This represented a 15.8% increase in Europe but a significant 35.9% decline in the U.S. compared to the previous year. While the beginning of 2023 saw some relief in the industrial chain situation, the European market initially experienced rapid growth despite a slowdown. However, the latter half of the year was marred by high interest rates and policy uncertainties in countries such as the Netherlands, Belgium, and Italy, resulting in a substantial contraction in market demand. Although the company's revenue from the European market maintained modest growth, the growth rate declined by 55% compared to the previous month. Similar trends were observed in the U.S. market, exacerbated by the transition of California's NEM 2.0 policy to 3.0, which created a vacuum in the demand for distributed PV storage.

In 2023, the European and American market demand was significantly affected by uncertain policies, with expectations for gradual recovery in 2024. Throughout the year, power optimizer shipments fluctuated, reaching 6.4 million, 5.5 million, 3.3 million, and 2.2 million sets from Q1 to Q4 respectively. Inverter shipments followed a similar pattern, with 330000, 335000, 274000 and 74000 units shipped during the same period. Energy storage battery pack shipments also varied, with 221 MWh, 269 MWh, 121 MWh, and 133 MWh recorded from Q1 to Q4 respectively. However, in the latter half of 2023, impacted by lower demand and high inventory, SolarEdge's shipments experienced a sharp decline compared to the previous month.

Looking ahead to 2024, several developments are anticipated in the following regions:

By the latter half of 2023, Enphase faced increased pressure in both the US and European markets due to weakened demand for energy storage and high inventory levels.

In the US market, the transition to NEM 3.0 and elevated interest rates dampened investor confidence in residential solar storage investments. As per the company's investor communications, revenue from the US market dropped by 16% and 35% in the third and fourth quarters of 2023 respectively, compared to the previous quarters. Notably, the California market experienced a sharper decline, with Enphase's microinverter sales falling by 25% and 27% in Q3 and Q4 respectively, while non-California markets remained relatively stable.

In Europe, the anticipated demand recovery in the latter half of 2023 fell short of expectations, exacerbating distributor inventory backlogs. Enphase's top three European markets—Netherlands, France, and Germany—faced distinct challenges. The Netherlands saw hesitancy among users awaiting the removal of the net metering program, while seasonality impacted the French market, and the German market grappled with feed-in tariff reductions. Consequently, market demand and shipments related to residential PV in major European countries all experienced declines.

According to Enphase's investor communication disclosures, microinverter shipments in 2023 were as follows: 4.8 million units in Q1, 5.2 million units in Q2, 3.9 million units in Q3, and 1.6 million units in Q4. Additionally, battery shipments totaled 102.0 MWh, 82.3 MWh, 86.0 MWh, and 80.7 MWh from Q1 to Q4 in 2023 respectively. However, in the latter half of 2023, microinverter shipments experienced a sharp decline due to weak demand and inventory accumulation. Enphase estimates that channel inventory will normalize by the end of Q2 in 2024, with shipments expected to increase again in Q3. Conversely, battery sales, buoyed by NEM 3.0, continue to rise.

Currently, the European market shows signs of recovery, while the California market is anticipated to gradually improve. The Dutch parliament recently confirmed that net metering policy will remain unchanged in the short term, and electricity costs have increased in France and Germany. Consequently, it is expected that the company's business will reach its nadir in the first quarter of 2024. In the United States, non-California markets are poised for swift recovery after interest rate fluctuations. However, the California market's recovery may take several quarters due to the transition from NEM 2.0 to NEM 3.0. Nevertheless, given the high electricity costs, the integration of solar and energy storage offers a higher return on investment under NEM 3.0, leading to a gradual recovery in market demand.

Rising Popularity: Unveiling the Growing Appeal of the Energy Storage Industrial Chain

In 2023, amidst a fierce price war among suppliers and a fragmented competitive landscape, the domestic energy storage companies find themselves heavily reliant on mandatory policy installations. Concerns about future development loom large among market participants, prompting a swift pivot towards overseas expansion.

But why the sudden surge in interest in foreign markets? The answer lies in the fact that domestic companies are encountering developmental roadblocks, compelling leading manufacturers to prioritize expansion abroad. In this article, TrendForce will delve into the challenges and opportunities facing China's energy storage industry as it ventures into the lucrative U.S. market, shedding light on the strategies and hurdles involved in this global endeavor.

Lithium-battery Industrial Chain Highlights in China

China stands out in the global lithium-ion battery supply chain, boasting distinct advantages. From cathodes and anodes to electrolytes, diaphragms, and batteries, China boasts a comprehensive industry chain for lithium-ion batteries.

Conversely, the United States grapples with insufficient local battery supply, relying heavily on the global supply chain to meet its energy storage system needs over the long term. As local demand surges, the United States has emerged as a primary destination for battery manufacturers to export their products.

Since the IRA Act came into effect, storage battery companies worldwide have ramped up their efforts to build new battery capacity in the United States. However, Japanese and Korean companies predominantly focus on producing ternary batteries. Many of their lithium-ion battery plants in the U.S., either under construction or already operational, specialize in ternary power batteries.

As mentioned earlier, China boasts a complete industrial chain. However, due to its advanced supply chain and fierce market competition, the average price of China's ESS is lower than that in Europe and the U.S. Consequently, in the United States, expanding local battery capacity in the short term poses challenges. Nonetheless, aided by U.S. subsidy policies and transport cost considerations, China's energy storage system products remain highly competitive in the U.S. market.

Wood Mackenzie anticipates that the capacity of energy storage batteries in the United States falls short of meeting the demands of its energy storage market. Moreover, the IRA Act mandates certain requirements, such as localizing key minerals and battery modules, to qualify for electric vehicle subsidies. However, there are no specific provisions regarding the ESS supply chain in the IRA Act. As a result, in the short term, ESS systems reliant on lithium iron phosphate will heavily depend on the global supply chain, particularly on China's supply of lithium iron phosphate batteries.

Chinese battery manufacturers continue to lead the way in global energy storage battery shipments. According to data released by SNE Research, an international battery market research institution, on March 11, 2024, Chinese companies maintained their dominance in global energy storage battery shipments throughout 2023. The data reveals that global energy storage battery shipments in 2023 totaled 185GWh, with the top five spots occupied by Chinese companies: CATL, BYD, EVE Battery, REPT, and Hithium.

In 2023, the global energy storage market continued to be dominated by China, North America, and Europe. Demand for energy storage batteries in North America and Europe reached 55GWh and 23GWh respectively, accounting for 30% and 12% of the market share. Meanwhile, the Chinese market saw demand soar to 84GWh, securing a commanding 45% market share.

Currently, Electrochemical Storage Systems (ESS) remain unaffected by the Foreign Entity of Concern (FEOC) regulations in the IRA Act. This implies that the U.S. has yet to impose restrictions on imports of energy storage batteries from China. Consequently, Chinese manufacturers still hold sway in both the U.S. and European markets. With the U.S. electrochemical energy storage market witnessing robust growth and China's lithium-ion battery industry boasting superior scale and technological prowess globally, manufacturers stand to gain significantly by tapping into high-value segments of the industry chain and leveraging advanced technologies.

Regarding ESS, according to data from CNESA, the top five companies in global ESS shipments for 2023 are Sungrow, CRRC Zhuzhou, Hyperstrong, Narada Power, and Envision Energy. Chinese energy storage system integrators are rapidly expanding into overseas markets, aiming to cater to diverse scenarios and enhance their presence across multiple global markets.

As capacity continues to grow, Chinese energy storage enterprises are increasingly targeting overseas markets. Energy transformation and green development represent inevitable trends in global economic progress, with the new energy industry in various countries and regions experiencing rapid expansion. Consequently, the potential for growth in overseas markets is virtually limitless.

Furthermore, Chinese battery companies lead the way in technology, production capacity, scale, and various other aspects. Their integrated industry chain and cost advantage serve as crucial assets, with relevant enterprises actively promoting research and development in battery technologies and strategic planning. Consequently, their competitiveness in the international market is steadily increasing.

Looking ahead, China, the United States, and Europe will remain the world's most significant regional markets for energy storage. Leveraging advantages such as the introduction of new technologies, cost efficiency, diverse product application scenarios, and expanding overseas markets, Chinese energy storage enterprises can enhance their global competitiveness.

The future in grid scale batteries

We are trying to cleanup our environment yet we are using multi mineral batteries (think lithium) to store energy at some PV solar and wind farms. Someday all of the lithium batteries will be wearing out and we will need to recycle as much as possible and yet what can not be recycled will go into landfills. Iron flow batteries will be the alternative. ESS Inc. has an iron flow battery in production that they describe as being 100% recyclable.

Europe Sparks Change with Electricity Market Reform, Paving the Way for Robust Utility Energy Storage Growth Across Nations

As the use of renewable energy installations rises, there's an increasing need for flexible resources on the grid. The International Energy Agency (IEA) has assessed factors like national grid load curves and renewable energy generation, finding that European countries like Denmark, Germany, Ireland, Spain, the UK, and Italy now have over 15% of their energy generated from renewables. However, the impact of renewable energy on power system operation varies due to differences in each country's grid and flexibility resources.

Traditionally, thermal power, gas generation, and pumped storage plants have dominated power system flexibility resources. Yet, with the global push for decarbonization, battery storage, hydrogen energy, demand-side response, and grid transmission channels are emerging as crucial components of future flexibility resources. According to IEA predictions, battery storage is expected to contribute 30% of flexible power resources by 2050, while the share of fossil fuels will be reduced to less than 5%.

Currently, natural gas peaking power plants play a vital role in regulating flexibility in the European power market. Additionally, certain parts of Europe rely more on hydropower and nuclear power for flexibility support. However, in the last two years, factors such as increasing fuel and carbon prices, maintenance issues with nuclear power units, and insufficient hydropower water have strained flexibility resources in Europe, resulting in a sharp surge in electricity prices.

The electricity reform is poised to expedite the implementation of utility storage.

Faced with the most severe energy crisis in decades, the European Union (EU) has introduced a series of policies to fast-track the transition to clean energy since 2021, including Fit-for-55 and REPowerEU. However, the substantial surge in European electricity prices in 2022 compelled the EU to reassess the existing power market design, which relied on marginal cost pricing.

Moreover, the EU had to unveil a more adaptive power market reform program for renewable energy development at the beginning of 2023. This initiative is anticipated to hasten the deployment of European renewable energy, along with flexible resources such as energy storage and demand-side response.

On March 14, 2023, the European Commission unveiled a preliminary proposal for an electricity market overhaul, followed by the European Parliament formally endorsing the EMD on July 19.

The primary focus of this reform is geared towards enhancing the liquidity and dependability of the long-term electricity market. It aims to incentivize renewable energy producers to engage in long-term power purchase contracts (PPAs) and government-approved contracts for difference (CfDs), thereby mitigating short-term price fluctuations through adjustments to relevant EU electricity regulations. Additionally, the reform seeks to facilitate the integration of more non-fossil fuel-based flexibility resources into the grid, such as Energy Storage Systems (ESS) and demand-side response. Ultimately, the reform underscores the crucial role of new energy storage and endeavors to establish a reliable ESS infrastructure at the highest level.

Furthermore, on December 14, 2022, the European Parliament greenlit REPowerEU, a plan designed to expedite the approval and licensing processes for various renewable energy ventures, including battery energy storage. This move is anticipated to kickstart the deployment of utility energy storage projects across Europe.

The United Kingdom, serving as a key catalyst in the European energy storage market, has consistently surpassed an annual installation of over 1 GWh in recent years for energy storage power plants. The primary source of revenue for Energy Storage Systems (ESS) stems from ancillary services. With the European electricity reform initiatives aiming to fortify grid resilience and bolster the growth of energy storage power plants, it is foreseen that installations in the European ESS market will maintain a range of 3-5 GWh per year in the coming years.

The UK Leads in Installations, Italy Poised for a Surge

As per statistics from the European Association of Energy Storage (EASE), Europe witnessed a substantial increase in energy storage capacity in 2022, with a total addition of 4.5GW. The utility storage and residential storage sectors contributed 2GW and 2.5GW, respectively.

In the Fast-Track-to-Market (FTM) segment, the United Kingdom claimed the lion's share, representing 42% of Europe's utility storage market. Following closely were Ireland, Germany, and France, with respective shares of 16%, 12%, and 11% in total installations. Notably, the statistics suggest that Italy is on the cusp of a significant surge in installations.

Based on data from Bloomberg New Energy Finance (BNEF), the primary source of revenue for European utility storage projects is the provision of frequency response services. In 2022, over 80% of the revenue in the European energy storage market originated from the lucrative frequency response market in key countries, including the United Kingdom, Ireland, Germany, France, Belgium, and the Netherlands.

As the frequency response market approaches saturation in the future, European energy storage projects are expected to pivot towards tariff arbitrage and capacity markets. Currently, Spain and Italy's energy storage projects generate relatively high revenue through tariff arbitrage, but their investment costs remain unmet. To mitigate the risk associated with new projects, countries like the United Kingdom, Italy, Poland, Belgium, and others have instituted a capacity market mechanism for Energy Storage Systems (ESS). This ensures that ESS projects secure minimum gains through capacity contracts, reducing overall project risk.

According to the 2022 Italian capacity market auction plan, there's an anticipation of adding 1.1GW/6.6GWh of new battery storage systems in 2024. In June 2023, the Italian regulator approved updated auction rules for grid-scale energy storage, empowering Terna (the transmission system operator) to conduct large-scale auctions for battery storage systems. The initial auctions are slated for the end of 2023 or early 2024, coinciding with the approval of a 200MW/800MWh battery storage system project owned by Aura Power. Consequently, explosive growth in installations is expected in Italy over the next few years.

Greece, Germany, and Spain have also implemented policies supporting utility-scale energy storage tenders and other initiatives, anticipating a significant boost in local utility-scale storage installations in the coming years.

As per the European Energy Storage Association forecast, the United Kingdom's favorable market mechanisms will further drive installation growth. Italy and Greece are poised for explosive growth in utility-scale installations between 2023-2025, thanks to supportive policies. Meanwhile, short-term installation growth in Ireland may be hampered by grid bottlenecks and other factors, but there remains potential for future growth.
