Can Bitcoin Mining Make Nuclear Energy Abundant And Free?

Welcome to part two of this series on Bitcoin and nuclear energy. Let us recap what we went through in part one before we dive deeper into the topics we’ll cover in part two.

Key Takeaways From “Why Bitcoin Is The Future Of Our Energy Grid”

1. Bitcoin has great utility and is important for humans. Not everyone may use or appreciate its utility today, which is fine, but that does not mean it holds no utility to others. Currently, close to $400 billion of the world’s wealth is stored in it, that’s a lot of monetary energy to disregard.
2. Bitcoin uses only about 0.1% of global energy. Current energy usage is between 100 to 200 terawatt hours (TWh) per year and per the projections shared in part one, Bitcoin’s energy usage will always be a rounding error with regards to global energy consumption. It would most likely be sub-1% for a long time to come.
3. Bitcoin, in fact, may use too little energy for the value it may store in the future. Considering that Bitcoin likely grows over this coming decade and could store $20 trillion of world’s wealth, maybe even $50 trillion or $100 trillion, that’s a lot of monetary energy to be secured safely and protected. We should invest and use more energy to protect the network than we do currently.
4. Bitcoin miners are highly mobile, look for the cheapest and lowest cost energy to mine and do not compete with other industries or your personal use for energy.
5. Energy usage is a good thing. You want to live in a place where there is a good amount of energy available to use and enjoy, rather than too little. We need to use and harness more energy to become a Kardashev Type-I civilization which will take decades.

Nuclear plants have always fascinated people over the years but very few average people to date actually understand the economics behind constructing a nuclear power plant at scale. Today we deconstruct this very topic and in a fun and innovative way.

As the industry saying goes, “There are only two things that matter in construction of a nuclear power plant — capital cost and the costs of capital”

A Tale That Begins In 2009

All good tales need to start from the very beginning. Why should we do it any differently? So here we go.

The year is 2009. There are two nuclear reactor technology companies in the market competing to bring their technology online, deploy reactors and sell electricity. We’ll call these companies Alpha Labs and Beta Labs. 

Both companies are currently in their R&D phases and going through their conceptual design for the reactor deployment. The next six or so years would be grueling. Both of these companies will go through extensive R&D, engineering decision making processes, supplier and vendor selections, component testing, hardware testing, conceptual design reviews and iterations and a thorough licensing review by the Nuclear Regulatory Commission (NRC) before they get a construction permit for building a nuclear reactor site. This period will be filled with challenges, both technological and otherwise. Like working on any deep technology, there are always things that need detailed design and engineering to be worked through and iterated upon before you’re ready to bring that technology to reality. The nuclear sector is no different.

However, another thing happened around 2009: the invention or discovery of Bitcoin. In the initial years no one took any notice, at least not in the nuclear industry, since they were pretty occupied in their technology work and Bitcoin was only heard about or really found in the weeds of the internet. And who was really busy searching for that in those days? But this changed. In 2012, one engineer working at Alpha Labs discovered Bitcoin by chance, going through a Reddit blog post. This engineer was intrigued and started looking into it more. Being from an engineering background with deep experience in energy markets, he started thinking about bitcoin as a commodity with a production cost associated with it like any other commodity. He discovered proof-of-work mining. This led him down a rabbit hole which changed the very nature of Alpha Labs’ history and, more importantly, the future of nuclear energy, power markets, the energy grid and humanity forever. This is the story of that one engineer.

The engineer started with mining bitcoin at his home in the beginning. He figured there was no better way of learning about mining than to do it himself and be in the trenches. The year was now 2013 and he had been mining for a good six months and had developed deep thinking about mining. He soon realized the repercussions of this innovation, how mining could be used to monetize energy that could otherwise never be monetized. Bitcoin mining offers a buyer of first resort for any energy that is low cost — wasted, stranded, curtailed, surplus or underutilized. The engineer realized this. He was way way ahead of his time, the world would not figure out the profoundness of this innovation until about 2030.

The engineer, having realized this in 2013, started pitching the idea of a co-location bitcoin mining site on the nuclear island that Alpha Labs was designing for its first site. He received severe pushback in the beginning since no one was aware of Bitcoin, much less of bitcoin mining. But he was persistent and did not give up.

Bitcoin had also started to get into the mainstream news because of a price surge, then a subsequent crash due to the Mt. Gox debacle, and more people were at least becoming aware of it. He started giving talks and presentations to the executive team and orange pilled a few of them. After six months of thorough design and engineering work in early 2014, Alpha Labs announced its plan to co-locate a bitcoin mining center on its nuclear island site, which was supposed to begin construction in 2016.

The engineer got switched to a newly-created bitcoin mining division inside the company and started leading that group. Over the next year, the team worked through the details of the build out and integrated the mining center co-location design into its nuclear island design. Alpha Labs went with a highly-mobile construction design for its mining center, so that in case it had to move or shift the mining center elsewhere it would be relatively easy to do, plus this limited its risk of owning an asset which cannot be moved if the circumstances demanded it. It realized the footprint that the mining center took as part of the nuclear island itself was not substantial and did not have a huge impact (increase) to the size of land it would need to get to build the site.

Alpha Labs received the permit approval for construction of Alpha-1, its flagship nuclear plant with the bitcoin mining co-location in the second half of 2016. It was now ready for construction.

All this was happening while Beta Labs was itself busy developing its own technology for the nuclear reactor and making amazing progress. It had gone through the design process, completed its entire hardware and component testing by 2014 and had itself been keeping engagements with the NRC around the licensing piece as early as 2012. Beta Labs went with a traditional nuclear plant with no bitcoin mining co-location, since it was not sold on the idea of this innovation by anyone particular, even though it had heard about the announcement of Alpha Labs in the early part of 2014.

It had held some preliminary discussions to understand Alpha Labs’ decision making but decided against pursuing a similar strategy, partly due to the fact that there were no resources out in the public markets to guide it around the use case for bitcoin mining colocation with its reactor build out. Beta Labs itself received its permit approval for construction in the second half of 2016 and was ready for its own build out.

Both Alpha Labs and Beta Labs were pursuing a nuclear plant construction of 1 gigawatt electrical (GWe) (or 2.5 gigawatt thermal (GWth), with 40% efficiency) capacity from the very early days. In 2014, Alpha Labs shifted track and announced a 2 GWe (or 5 GWth, 40% efficiency) reactor deployment and construction plan, with 1GWe to be used for selling electricity to the grid while the balance of 1GWe was to be used solely for mining bitcoin onsite.

So, to recap, here is the construction plan for both companies:

Alpha Labs: 2 GWe cap., 1 GWe sell to grid wholesale, 1 GWe to mine bitcoin onsite

Beta Labs: 1 GWe cap., 1 GWe to sell to grid wholesale

Economics Of Nuclear Power Plants

We’re in the second half of 2016 now. Both Alpha and Beta Labs have announced their nuclear power plants (NPPs) constructions and are actively looking to raise capital.

NPP financing can take many different, exotic forms and arrangements. The structure of financing for NPPs is not part of the scope for this article. Here we would assume that both Alpha Labs and Beta Labs get funding on equal terms for their construction plants, so as to do an “apples-to-apples” projection of their capital costs, revenue and profits/losses.

Assumptions

• Let us assume that NPP construction for both companies will take six years to complete. So, from 2016 to 2022. This is in line with construction times of most NPPs to date.
• Let us assume that the capital costs for NPP construction for both companies are $5,000 per kilowatt (kW). This ballpark estimate is in line with the construction costs of NPPs to date.

Based on this number, here are the capital requirements for both companies:

Alpha Labs: $5,000 * 2 Gw/Kw = $10 billion

Beta Labs: $5,000 * 1 Gw/Kw = $5 billion

Now, keep in mind that Alpha Labs would also require capital to buy miners and deploy them onsite at its co-located mining center. But this would only be required when it is ready to produce electricity, which would not happen until 2022. So, it decides to get a higher limit of capital line which they can draw upon when needed six years down the line. At this point in 2016, bitcoin ASICs were going mainstream, new and more efficient machines were expected to come to market over the coming years, which Alpha Labs was keeping a track of. It was still quite a few years away from placing orders for miners, that would consume 1 GWe of nuclear generation, so the only thing to do right then was to track the mining industry and see it evolve.

Here are the funding terms received by both companies:

Alpha Labs: $10 billion at 3% interest, with a debt service period of 25 years. The capital line would be extended up to $15 billion at the same terms if needed in the future. Alpha Labs would draw $2 billion in each year for the first five years of NPP construction.

Beta Labs: $5 billion at 3% interest, with a debt service period of 25 years. Beta Labs would draw $1 billion in each year for the first five years of NPP construction.

Now, based on the terms, Beta Labs would need to pay about $57 million every year for the next 25 years for every $1 billion it drew from its capital line during the first five years of construction.

And, on similar lines, Alpha…
