Reasons to Invest

Battery Energy Storage System Market Size is projected to reach USD 6.9 Billion by 2025 - a 4.7 Billion jump since 2019. Because our systems can be scaled to meet any consumer or commercial power needs, much of the market is in our grasp.
The growing renewable energy sector, which increases the need for energy storage, is expected to promulgate the market.
The demand for uninterrupted power is expected to rise exponentially in the coming years due to continuous population growth, infrastructure development, rapid industrialization, and ever-increasing environmental volatility.


Meet Blue Sky Energy - Bringing You Clean, Safe Energy Storage

When thinking of energy conservation, solar power is often the first thing that comes to mind. But with the reality and unpredictability of climate change - we can’t always expect the sun to do the work on its own.

That’s where energy storage comes in, with BlueSky Energy as your leading, sustainable force. We create safe and reliable power storage systems to maximize the capture and re-use of renewable energy sources with a focus on minimizing environmental impact.

Clean Energy Storage for Clean Energy

The Problem

Climate Change is Happening

And while the current renewable energy sector is doing all it can, we are still all being affected. 

Within that sector, you need energy storage: AKA batteries. Batteries store your renewable energy so you can use it when you need it - without being affected by changing weather conditions. 

While the battery industry is solving some problems in renewable energy, it's also contributing to others by using scarce, expensive, and sometimes harmful materials like cobalt. We believe there aren't enough energy solutions that provide people with clean, safe, reliable alternatives to these products.

The Solution

Harmless Batteries for You and the Planet

We wanted to provide solutions to battery storage that were better both for the consumer and the environment.

We do this in two ways…

  1. The Saltwater Battery: totally green, endurance-based battery
  2.  VIGOS: a power-based solution with twice the lifespan of other batteries, free from harmful mining practices like those required with cobalt

The Market

A Green Market Only Getting Greener 

Battery Energy Storage System Market Size is projected to reach USD 6.9 Billion (source) by 2025 - that’s more than three times the size it was in 2019.  

With declining prices of lithium-ion batteries, and increased demand for uninterrupted power supplies, the North American energy storage market alone is expected to grow at a CAGR of approximately 46.35% (source) during the same forecast period. 

Also, the growing renewable energy sector, which accelerates the need for energy storage, is expected to propagate that market.

Our Traction

Our Milestones

Here’s a timeline of some of our recent successes, and upcoming ones:

  • In 2017 we sold our first Greenrock Saltwater Plug & Play system, and now we have installed over 500 systems around the world (source)

  •  In 2019, we began selling power systems in North America with a formal expansion into our US headquarters in 2020.

  • In Jan. 2021, Austria shipped the first VIGOS, installing 3 All-Weather Systems across Europe. This product will be available to us in the United States in Q2 of 2021, and is already gaining traction within our consumer population.

  • By Q2 of 2021, we expect a third flagship product, CEL3050, will be released and is a smaller version of VIGOS 


What We Do

Green Energy Storage to Meet Your Needs 

From small homeowners to large industrial conglomerates - it’s important to us to learn about our customers' varying needs. 

That’s why we designed systems using our product range of high-powered VIGOS or endurance-based Saltwater batteries, and integrate them with various fabricated or off-the-shelf parts such as inverters, controllers, cables, and battery management systems. 


Additional Battery Specifications:

The Saltwater Battery: 

  • 100% renewable, safe and made from abundant materials. 
  • No harmful mining practices, no extraction of rare-earth materials
  • Toxic-free, with no special shipping or handling required  (highly uncommon in the energy storage industry)

Vigos Battery:  

  • Made from LTO (Lithium Titanate Oxide)

  • A safe, non-flammable, non-explosive Lithium-based product without Cobalt

  • Lasts twice as long as NMC and LFP Lithium technologies 

  • Operates in a much wider temperature range of -30C to +50C (source)

The Business Model

Organic Means to Organic Success

Like our product, our sales process will evolve in the coming years - keeping up with the growth of renewable energy and all of its subsequent demand.

With our current systems sold for $15K-$100K each, we’ve had organic, successful traction mainly reaching customers through referral or word of mouth. Our on-the-ground approach has been widely successful. In our first year in the US, we reached USD $370k of revenue with minimal marketing and outreach efforts, and our parent company earned an additional EUR $3M in 2020.


How We Are Different

In a League of Our Own

Our industry and competitors predominantly use NMC and LFP technology, meaning they are made up of Lithium-phosphate or Lithium, Manganese, and Cobalt as cathode materials. We stand in a unique position, as our technology is none of those.


We offer similar solutions as other major players, just in a greener, safer, and more sustainable form. We believe we are the only company to build a system that meets the Living Building Challenge standards for energy storage - architecture's greenest energy standard.

The Vision

The Future of Green Power

We aim to offer one-of-a-kind energy storage solutions that are safe, clean, efficient, and reliable. And we’re at the cusp of major growth, innovation, and development.

Where we are heading:

  • Acquiring a large network of installers to reduce internal costs
  •  Bidding on larger, industrial-sized projects, expanding production to the US in Idaho, and a future site in Canada, allowing us to scale exponentially
  • Employing local workforces from skilled engineers to production teams, and everyone in between


Leaders Across the Globe

In 2012, our parent company, BlueSky Energy Gmbh, was founded in Frankenburg, Austria by Hansjoerg Weisskopf.

After a successful career in high-tech contract manufacturing, Hansjoerg saw the need for energy storage as a required enabler for the growing renewable energy market.

Since then, Blue Sky has built its foundation on a bedrock of strong leadership spanning between the US and Europe. From Austria to Idaho, between all Blue Sky entities, we have 65 employees forging ahead with one collective vision.

Why BlueSky Energy USA Battery Systems

26 days ago

Our mission at BlueSky Energy USA is to deliver battery systems that are safe, clean, and affordable to residential and commercial customers.  BlueSky Energy designs, builds, and sells battery storage systems using environmentally friendly and inherently safe technologies: saltwater or Lithium Titanate Oxide (LTO) systems.  Saltwater and LTO batteries are safer and have longer life cycles than most lead-acid or lithium batteries.  This makes our battery technology solutions ideal for homeowners and commercial applications.  

BlueSky Energy Batteries Will Keep the Lights On 

Solar power alone is not a comprehensive solution to energy independence.  Installations in locations with shorter days in the winter and prolong periods of cloudy days result in insufficient solar PV to meet energy consumption needs – therefore, resulting in having to utilize power from the energy grid.  A solar powered battery system is essential to achieving energy independence – it allows you to store excess energy during peak solar PV times to use later at night or during cloudy days. 

Blackouts due to excessive heat during the summer months and power outages due to extreme weather or wildfire events are happening more frequently in recent years.  Power outages are not only inconvenient – but also dangerous and costly to homeowners and businesses.  By simply installing rechargeable batteries this will allow continued access to electricity during power outages.  BlueSky Energy batteries are also certified for use in a wide variety of temperature ranges which means they can be installed in very extreme climates from Grand Forks, ND to Yuma, AZ.

BlueSky Energy Batteries are User-Friendly and Business-Friendly

Our battery systems are completely maintenance free and optimized for deep discharge.  Depending on your installation requirements – we have a battery system solution that is compatible with all-weather environments.  

Why BlueSky Energy batteries?

  • Safe, non-flammable and non-explosive
  • Plug & Play, ready-to-connect complete battery storage system
  • Long Lifespan, 10+ years for Saltwater and 15+ years/20,000 cycles for VIGOS LTO
  • Daily Deep Discharge, 80% for Saltwater and 100% for VIGOS LTO
  • Warranty our battery systems for 10 years
