$480,707.85 Raised


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.

An update about BlueSky Energy ceasing operations was posted but now appears to have been removed. What is the situation? Besides this removed update, I have heard nothing by email and there is nothing I can see on their website on them stopping operations.

Has anyone contacted StartEngine on this? Will StartEngine reach out to their contact at BlueSky Energy to see what is going on and the status of investors’ shares? What help, if any, does StartEngine give their customers/investors in these types of situations?



Fred Bonyadian

This turn of events is disappointing to say the least! Could someone provide clarity as to the status of our investments. Should we put this in the loss column? Does the parent company in Austria accept any responsibility? Closing down the operations is one thing, but what happened to the funds raised? Will the investors receive any refunds? Or will someone provide an accounting of expenditures? Investing in a high risk startup is one thing, but not having any transparency is unreasonable if not unconscionable.

Railroads may be a good market for your saltwater batteries. Most diesel locomotives actually have electric motors and the diesels run generators to feed the motors, which is really inefficient. One advantage to fully electrifying railroads is that they can use lower power density batteries, so less materials conflict with EVs. (Only about 1/3 of the volume of a "battery car" for each locomotive would be needed using lithium ion batteries - so your saltwater batteries would be a perfect fit.)

With Regulation A+, a non-accredited investor can only invest a maximum of 10% of their annual income or 10% of their net worth per year, whichever is greater. There are no restrictions for accredited investors.

With Regulation Crowdfunding, non-accredited investors with an annual income or net worth less than $124,000, are limited to invest a maximum of 5% of the greater of those two amounts. For those with an annual income and net worth greater than $124,000, he/she is limited to investing 10% of the greater of the two amounts.

At the close of an offering, all investors whose funds have “cleared” by this time will be included in the disbursement. At this time, each investor will receive an email from StartEngine with their Countersigned Subscription Agreement, which will serve as their proof of purchase moving forward.

Please keep in mind that a company can conduct a series of “closes” or withdrawals of funds throughout the duration of the campaign. If you are included in that withdrawal period, you will be emailed your countersigned subscription agreement and proof of purchase immediately following that withdrawal.

StartEngine assists companies in raising capital, and once the offering is closed, we are no longer involved with whether the company chooses to list shares on a secondary market, or what occurs thereafter. Therefore, StartEngine has no control or insight into your investment after the close of the live offering. In addition, we are not permitted to provide financial advice. You may want to contact a financial professional to discuss possible investment outcomes.

For Regulation Crowdfunding, investors are able to cancel their investment at any point throughout the campaign up until 48 hours before the closing of the offering. Note: If the company does a rolling close, they will post an update to their current investors, giving them the opportunity to cancel during this timeframe. If you do not cancel within this 5-day timeframe, your funds will be invested in the company, and you will no longer be able to cancel the investment. If your funds show as ‘Invested’ on your account dashboard, your investment can no longer be canceled.

For Regulation A+, StartEngine allows for a four-hour cancelation period. Once the four-hour window has passed, it is up to each company to set their own cancelation policy. You may find the company’s cancelation policy in the company’s offering circular.

Once your investment is canceled, there is a 10-day clearing period (from the date your investment was submitted). After your funds have cleared the bank, you will receive your refund within 10 business days.

Refunds that are made through ACH payments can take up to 10 business days to clear. Unfortunately, we are at the mercy of the bank, but we will do everything we can to get you your refund as soon as possible. However, every investment needs to go through the clearing process in order to get sent back to the account associated with the investment.

Both Title III (Regulation Crowdfunding) and Title IV (Reg A+) help entrepreneurs crowdfund capital investments from unaccredited and accredited investors. The differences between these regulations are related to the investor limitations, the differing amounts of money companies are permitted to raise, and differing disclosure and filing requirements.
