In a move that could reshape the narrative around Bitcoin mining’s environmental impact, blockchain infrastructure company Blockstream Mining and financial services firm Block, Inc announced on April 13, 2022, that they have begun construction on a fully solar-powered Bitcoin mining facility in the United States. The proof-of-concept project will use Tesla’s Megapack battery storage systems and solar PV technology to power the operation entirely off-grid.
TL;DR
- Blockstream Mining and Block, Inc building a 100% solar-powered Bitcoin mining facility in the US
- Tesla supplying 3.8MW solar array and 12MWh Megapack battery storage
- Facility targets 30 Petahash hash rate using only renewable energy
- Jack Dorsey’s Block partnering with Adam Back’s Blockstream on the project
- Public dashboard will show real-time mining performance and energy metrics
A Groundbreaking Partnership Takes Shape
The collaboration brings together three major players from different corners of the technology world. Blockstream Mining, led by CEO and co-founder Adam Back, is providing the Bitcoin mining expertise. Block, Inc—the financial services company formerly known as Square, led by Twitter co-founder Jack Dorsey—is contributing its digital payments and financial infrastructure knowledge. Tesla, the electric vehicle and clean energy giant headed by Elon Musk, is supplying the hardware that makes the 100% renewable approach possible.
Construction on the open-source, solar-powered facility at an undisclosed US location began in early April 2022. The project represents what the partners describe as a proof of concept aimed at demonstrating that Bitcoin mining can be economically viable without relying on fossil fuels.
Tesla’s Megapack at the Center of the Operation
The mining facility will pair a 3.8-megawatt solar PV array with 12 megawatt-hours of Tesla Megapack battery energy storage. The Megapack units will store excess solar energy generated during peak sunlight hours, ensuring continuous mining operations even when the sun isn’t shining. The combined system is designed to deliver a hash rate of 30 Petahash—a measure of the computational power used in Bitcoin’s proof-of-work consensus mechanism.
To ensure transparency and allow the broader community to evaluate the project’s performance, the partners plan to launch a publicly accessible dashboard. This dashboard will display real-time metrics including power output, energy consumption, and the amount of Bitcoin mined, giving unprecedented visibility into the economics of renewable-powered mining.
Bridging the Gap Between Crypto and Clean Energy
Blockstream’s Adam Back framed the initiative as a step toward proving a broader thesis: that Bitcoin mining can actually fund the development of zero-emission power infrastructure. “This will be a step to proving our thesis that Bitcoin mining can fund zero-emission power infrastructure and build economic growth for the future,” Back stated.
Neil Jorgensen, Block’s global ESG lead, echoed this sentiment. “By collaborating on this full-stack, 100% solar-powered Bitcoin mining project with Blockstream, using solar and storage technology from Tesla, we aim to further accelerate Bitcoin’s synergy with renewables,” he said.
Elon Musk’s Complicated History With Bitcoin
The project carries particular significance given Tesla CEO Elon Musk’s complicated relationship with Bitcoin. In early 2021, Tesla announced it had purchased $1.5 billion worth of Bitcoin and would begin accepting the cryptocurrency as payment for its vehicles. However, just months later in May 2021, Musk reversed course, suspending Bitcoin payments over concerns about the “rapidly increasing use of fossil fuels for Bitcoin mining and transactions.”
That decision sent shockwaves through the crypto market and intensified the debate around Bitcoin’s energy consumption. The new solar-powered mining project, which directly involves Tesla’s energy storage technology, could be interpreted as Musk’s company taking a constructive approach to the problem rather than simply walking away from it.
The Bigger Picture for Green Mining
The Blockstream-Block-Tesla initiative arrives at a time when Bitcoin mining’s environmental footprint faces unprecedented scrutiny from regulators, investors, and the public. The Cambridge Bitcoin Electricity Consumption Index has consistently shown that Bitcoin mining consumes more electricity than many individual countries, though the proportion derived from renewable sources remains a subject of debate.
If successful, this proof-of-concept facility could serve as a blueprint for future mining operations. The combination of declining solar costs, improving battery storage technology, and Bitcoin mining’s inherent flexibility—miners can locate anywhere with cheap electricity—creates a compelling case for renewable-powered operations. The open-source nature of the project means that other companies and mining operations could replicate the model without paying licensing fees.
Why This Matters
This collaboration between three high-profile companies represents one of the most concrete steps yet toward addressing Bitcoin mining’s most persistent criticism. By proving that a mining operation can run entirely on solar power with battery backup, the project could shift the conversation from whether Bitcoin mining can be sustainable to how quickly the industry can transition to clean energy sources.
For the broader crypto market, the timing is significant. With Bitcoin trading at around $41,167 on April 13, 2022, and facing ongoing pressure over its energy consumption, a successful green mining demonstration could bolster the case for institutional adoption. It could also preempt regulatory action in jurisdictions that have considered restricting or banning crypto mining due to environmental concerns. The project’s public dashboard approach adds a layer of accountability that has been largely absent from the industry, potentially setting a new standard for transparency in Bitcoin mining operations worldwide.

3.8MW solar array running 30 PH/s is a proof of concept, not a real mining operation. Still cool that Dorsey and Adam Back got Elon involved
30 petahash is literally nothing in the grand scheme of the network. but as a PR move against the ESG crowd it was brilliant
A public dashboard showing real-time performance metrics was the smartest part of this. Transparency matters when everyone accuses mining of killing the planet.
12MWh of Tesla Megapack storage paired with solar is actually undersized for continuous mining. Wonder if they ever scaled it
