Despite The Rapid Global Reduction In Energy Storage Costs, Brazil Continues To Pay More For Batteries Due To Tax Burden And Logistics. EPE Study Forecasts New Drops Until 2035 And Points To Impact On The Advancement Of Solar Systems With Storage.

The Discussion About Energy Storage Has Intensified, Mainly Because Brazil Still Faces Higher Costs Compared To The International Scene. Although The Global Market Shows Strong Expansion And Accelerating Price Drops For Batteries, The Brazilian Reality Is Marked By Tax And Logistics Barriers That Affect The Sector’s Competitiveness.

International Battery Prices Plummet, According To EPE Study

According To The Energy Research Company (EPE), The Global Lithium-Ion Battery Market Has Undergone Profound Transformations In Recent Years. Between 2017 And 2024, The Decline Was Significant. During This Period, The Pack Dropped From US$ 266/kWh To US$ 115/kWh, While The Complete System Fell From US$ 614/kWh To US$ 165/kWh.

This Data Explains Why The Adoption Of Storage Systems Is Growing So Rapidly, Especially In Countries That Already Use Batteries For Grid Stabilization And Integration With Solar Energy.

Trend Indicates More Reductions Until 2035, With Direct Impact On Competitiveness

EPE’s Projections Indicate That The Advancement Should Not Slow Down Anytime Soon. On The Contrary: BESS Systems May Register An Additional Reduction Ranging From 45% To 57% Until 2035. Furthermore, The Sector Is Expected To Achieve Significant Gains In Energy Density And Lifespan.

As A Result, The Savings Provided By Batteries Are Likely To Approach — And Even Surpass — Alternatives Such As Diesel Generators Used During Peak Hours. Starting In 2029, When New Rules For Valuing Energy Injected Into The Grid Come Into Effect, This Change Could Drive The Adoption Of Storage In Residential Photovoltaic Systems.

Despite Global Fall, Brazil Continues To Pay More For Batteries

Despite International Progress, The Brazilian Market Still Feels The Weight Of High Costs. EPE Emphasizes That The Tax Burden And Logistics Challenges Are Determinants For The Final Price.

For Commercial And Industrial Applications, A 3 MWh System Can Reach R$ 2,000/kWh, A Value That Includes 70.8% In Taxes, 13% In EPC/BOS, And 5% In Logistics. This Scenario Reduces The Attractiveness Of Investment, Even In The Face Of Global Cost Reductions For Equipment.

The Residential Segment Faces An Even Greater Challenge. In Hybrid Photovoltaic Systems, The Estimated Price Of Batteries Reaches R$ 3,500/kWh.

Although Between 2020 And 2024 There Was A Reduction In The Total Cost Of Installations With Storage, This Modality Remains Significantly More Expensive Than Solar Systems Without Batteries. This Explains Why Adoption Is Still Progressing Slowly In Residences, Despite The Potential Gains In Autonomy And Energy Security.

A giant printer called the “Ferrari” of concrete has landed in Latin America and can already build a 120-square-meter house in just 48 hours, making the traditional construction site look like something from the last century.

Brazil will harvest a record crop of up to 357 million tons of grains, but it does not have the capacity to store a large part of it. The storage deficit has reached the highest level in history and is equivalent to almost the entire production of Argentina.

Four times faster than the Concorde, capable of taking passengers from New York to London in less than an hour at Mach 5.5, and with an engine that switches from turbojet to ramjet mid-flight at Mach 3.5, the Hermeus Quarterhorse went from paper to its first flight in just 19 months.

Under nearly 2 kilometers of ice in Antarctica, scientists have discovered an ancient landscape sculpted by rivers up to 60 million years ago, the size of Wales, preserved as a time capsule that could help predict the advance of ice towards the ocean.

She started by collecting oyster shells from restaurants and today she has already accumulated more than 10 tons to restore reefs, recover coastal habitats, and demonstrate how a common waste can become a tool for ocean conservation.

SpaceX will dock a $843 million vehicle to the International Space Station to push a nearly 420-ton laboratory against the atmosphere and make the debris fall in a controlled manner into the ocean.

Tax reform raises an alert in industrial engineering and puts EPC contracts, heavy infrastructure, and large projects at the center of the debate.

Scientists discover that the Moon underwent an explosion so devastating that it would take detonating 130 of Earth’s nuclear arsenals to reproduce the force that created its gigantic lunar canyons in just a few minutes.

China ‘decrees’ the end of diesel: new maritime engine of 1,953 tons and 64,500 kW runs on more than 95% methanol, uses 5G technology, and could forever change the giant 16,000-container ships

Young person creates system that transforms plastic into gasoline and even says: ‘people call it trash; I call it a resource’; 22-year-old self-taught individual goes viral for using pyrolysis to convert waste into fuel on a planet that produces 440 million tons of plastic per year.

Cold air mass advances through the Atlantic, drops temperatures in the Southeast, and may even surprise the Northeast with heavy rain in Bahia and minimums below 10ºC in the interior.
