Return to the Investor Forum Event Page

Blue Sky Uranium Corp. (TSX.V: BSK; FSE: MAL2.F; OTC: BKUCF) is one of Argentina’s best-positioned uranium & vanadium exploration companies with more than 4,000 km2 (400,000 ha) of prospective tenements. The Company’s mission is to deliver exceptional returns to shareholders by acquiring, exploring and advancing towards production a portfolio of uranium-vanadium projects, with an emphasis on near-surface deposits with the potential for near-term low-cost production. The Company follows international best practices in exploration, with a focus on respect for the environment, the communities, and the cultures in all the areas in which we work.

Argentina is the largest generator of electricity from nuclear energy in South America. The country is working to further expand their nuclear energy sector with additional power plants, but currently lacks domestic uranium production. Argentina’s desire for security of supply could provide a “guaranteed” first customer for a new domestic supplier. Large scale production could make Argentina a strategic exporter of uranium to the international nuclear energy sector.

Blue Sky’s exploration work between 2007 and 2012 led to the discovery of a new uranium district in Rio Negro Province. The Company’s Amarillo Grande Project covers the district with three major properties, including the Ivana near-surface uranium deposit which hosts the largest NI 43-101 uranium resource in the country; Ivana also has potentially significant vanadium credits. Other exploration targets for blind uranium and vanadium mineralization are also present within the project area. The close proximity of the properties & targets provides the potential for an integrated, low-cost uranium-vanadium producing operation, making Amarillo Grande an excellent candidate to be the first near-term uranium producer in Argentina.

The Company is a member of the Grosso Group, a resource-focused management group that pioneered the mineral exploration industry in Argentina and has operated there since 1993. The group is credited with four exceptional mineral deposit discoveries, and has a highly-regarded track-record for fostering strong relationships with the communities and governments where it works. The Grosso Group leverages its vast network of local, regional and international industry contacts to support the exploration team as they search for quality resource opportunities.

Infinite Energy Through Nuclear Fusion


Nuclear Fusion Breakthrough: What Do New Results Mean for the Future of ‘Infinite’ Energy?

 

The Lawrence Livermore National Laboratory has announced a major breakthrough in nuclear fusion, using powerful lasers to produce 1.3 megajoules of energy – about 3% of the energy contained in 1kg of crude oil.

Nuclear fusion has long been thought of as the energy of the future – an “infinite” source of power that does not rely on the need to burn carbon. But after decades of research, it has yet to deliver on its exciting promise.

How much closer does this new breakthrough bring us to the desired results? Here is a brief overview to put this new scientific advance into perspective.

What is Nuclear Fusion?

There are two ways of using nuclear energy: fission, which is used in current nuclear power plants, and fusion.

In fission, heavy uranium atoms are broken into smaller atoms to release energy. Nuclear fusion is the opposite process: light atoms are transformed into heavier atoms to release energy, the same process that occurs within the plasma core of the Sun.

A fusion reactor amplifies power: the reaction triggered must produce more energy than is needed to heat the fuel plasma for energy production to occur – this is known as ignition. No one has managed this yet. The current record was achieved in 1997 by the Joint European Torus in the UK, where 16 megawatts of power were generated by magnetic fusion, but it took 23 megawatts to trigger it.

There are two possible ways of achieving nuclear fusion: magnetic confinement, which uses powerful magnets to confine the plasma for very long periods of time, and inertial confinement, which uses very powerful and brief laser pulses to compress the fuel and start the fusion reaction.

Historically, magnetic fusion has been favored because the technology needed for inertial fusion, particularly the lasers, was not available. Inertial fusion also requires much higher gains to compensate for the energy consumed by the lasers.

Inertial Confinement

The two largest inertial projects are the National Ignition Facility (NIF) at the Lawrence Livermore National Laboratory in the USA and the Laser MégaJoule in France, whose applications are mainly military and funded by defense programs. Both facilities simulate nuclear explosions for research purposes, though the NIF also carries out research on energy.

The NIF uses 192 laser beams that produce a total of 1.9 megajoules of energy for a period lasting a few nanoseconds to trigger the fusion reaction. Fuel is placed inside a metal capsule a few millimeters across, which, when heated by lasers, emits X-rays that heat up and compress the fuel.

It was this process that, on 8 August 2021, achieved the landmark energy production of 1.3 megajoules, the highest value ever recorded by the inertial approach. That is, the closest we have come to ignition.

The overall gain of 0.7 equals the record achieved by JET in 1997 using magnetic confinement. Still, in this case, the fuel absorbed 0.25 megajoules of energy and generated 1.3 megajoules: fusion, therefore, generated a good part of the heat needed for the reaction, approaching the point of ignition.

Still, a reactor will have to achieve much higher gains (more than 100) to be economically attractive.

 

Magnetic Confinement

The magnetic confinement approach promises better development prospects and is thus the preferred route for energy production so far.

The vast majority of research focuses on tokamaks, and fusion reactors invented in the USSR in the 1960s, where the plasma is confined by a strong magnetic field.

ITER, a demonstration reactor under construction in the south of France involving 35 countries, uses the tokamak configuration. It will be the world’s largest fusion reactor and aims to demonstrate a gain of 10 – the plasma will be heated by 50 megawatts of power and should generate 500 megawatts. The first plasma is now officially expected by the end of 2025, with a demonstration of fusion expected in the late 2030s.

The UK has recently launched the STEP project (Spherical Tokamak for Electricity Production), which aims to develop a reactor that connects to the energy grid in the 2040s. China is also pursuing an ambitious program to produce tritium isotopes and electricity in the 2040s. Finally, Europe plans to open another tokamak demonstrator, DEMO, in the 2050s.

Another configuration called the stellarator, like Germany’s Wendelstein-7X, is showing very good results. Though stellarator performances are lower than what a tokamak can achieve, its intrinsic stability and promising recent results make it a serious alternative.

 

The Future of Fusion

Meanwhile, private nuclear fusion projects have been booming in recent years. Most of them envision a fusion reaction in the next ten to 20 years and together have attracted US$2 billion in funding to outpace the traditional development sector.

While these initiatives use other innovative technologies to reach fusion and could thus very well deliver operational reactors fast, deploying a fleet of reactors throughout the world is bound to take time.

If development follows this accelerated track, nuclear fusion could amount to about 1% of global energy demand by 2060.

So while this new breakthrough is exciting, it’s worth keeping in mind that fusion will be an energy source for the second part of the century – at the earliest.

Technologies to Increase Battery Storage 3000 Percent

The National Renewable Energy Lab Sees Potential to Increase U.S. Energy Storage 3000%

 

In recent decades the cost of wind and solar power generation has dropped dramatically. This is one reason that the U.S. Department of Energy projects that renewable energy will be the fastest-growing U.S. energy source through 2050.

However, it’s still relatively expensive to store energy. And since renewable energy generation isn’t available all the time – it happens when the wind blows or the sun shines – storage is essential.

Kerry Rippy, Researcher, National Renewable Energy Laboratory

 

As a researcher at the National Renewable Energy Laboratory, I work with the federal government and private industry to develop renewable energy storage technologies. In a recent report, researchers at NREL estimated that the potential exists to increase U.S. renewable energy storage capacity by as much as 3,000% percent by 2050.

Here are three emerging technologies that could help make this happen.

Longer Charges

From alkaline batteries for small electronics to lithium-ion batteries for cars and laptops, most people already use batteries in many aspects of their daily lives. But there is still lots of room for growth.

For example, high-capacity batteries with long discharge times – up to 10 hours – could be valuable for storing solar power at night or increasing the range of electric vehicles. Right now there are very few such batteries in use. However, according to recent projections, upwards of 100 gigawatts’ worth of these batteries will likely be installed by 2050. For comparison, that’s 50 times the generating capacity of Hoover Dam. This could have a major impact on the viability of renewable energy.

One of the biggest obstacles is limited supplies of lithium and cobalt, which currently are essential for making lightweight, powerful batteries. According to some estimates, around 10% of the world’s lithium and nearly all of the world’s cobalt reserves will be depleted by 2050.

Furthermore, nearly 70% of the world’s cobalt is mined in the Congo, under conditions that have long been documented as inhumane.

Scientists are working to develop techniques for recycling lithium and cobalt batteries and to design batteries based on other materials. Tesla plans to produce cobalt-free batteries within the next few years. Others aim to replace lithium with sodium, which has properties very similar to lithium’s but is much more abundant.

Safer Batteries

Another priority is to make batteries safer. One area for improvement is electrolytes – the medium, often liquid, that allows an electric charge to flow from the battery’s anode, or negative terminal, to the cathode, or positive terminal.

When a battery is in use, charged particles in the electrolyte move around to balance out the charge of the electricity flowing out of the battery. Electrolytes often contain flammable materials. If they leak, the battery can overheat and catch fire or melt.

Scientists are developing solid electrolytes, which would make batteries more robust. It is much harder for particles to move around through solids than through liquids, but encouraging lab-scale results suggest that these batteries could be ready for use in electric vehicles in the coming years, with target dates for commercialization as early as 2026.

While solid-state batteries would be well suited for consumer electronics and electric vehicles, for large-scale energy storage, scientists are pursuing all-liquid designs called flow batteries.

 

A typical flow battery consists of two tanks of liquids that are pumped past a membrane held between two electrodes. Qi and Koenig, 2017CC BY

In these devices both the electrolyte and the electrodes are liquids. This allows for super-fast charging and makes it easy to make really big batteries. Currently these systems are very expensive, but research continues to bring down the price.

 

Storing Sunlight as Heat

Other renewable energy storage solutions cost less than batteries in some cases. For example, concentrated solar power plants use mirrors to concentrate sunlight, which heats up hundreds or thousands of tons of salt until it melts. This molten salt then is used to drive an electric generator, much as coal or nuclear power is used to heat steam and drive a generator in traditional plants.

These heated materials can also be stored to produce electricity when it is cloudy, or even at night. This approach allows concentrated solar power to work around the clock.

This idea could be adapted for use with non-solar power generation technologies. For example, electricity made with wind power could be used to heat salt for use later when it isn’t windy.

Concentrating solar power is still relatively expensive. To compete with other forms of energy generation and storage, it needs to become more efficient. One way to achieve this is to increase the temperature the salt is heated to, enabling more efficient electricity production. Unfortunately, the salts currently in use aren’t stable at high temperatures. Researchers are working to develop new salts or other materials that can withstand temperatures as high as 1,300 degrees Fahrenheit (705 C).

One leading idea for how to reach higher temperature involves heating up sand instead of salt, which can withstand the higher temperature. The sand would then be moved with conveyor belts from the heating point to storage. The Department of Energy recently announced funding for a pilot concentrated solar power plant based on this concept.

 

Advanced Renewable Fuels

Batteries are useful for short-term energy storage, and concentrated solar power plants could help stabilize the electric grid. However, utilities also need to store a lot of energy for indefinite amounts of time. This is a role for renewable fuels like hydrogen and ammonia. Utilities would store energy in these fuels by producing them with surplus power, when wind turbines and solar panels are generating more electricity than the utilities’ customers need.

Hydrogen and ammonia contain more energy per pound than batteries, so they work where batteries don’t. For example, they could be used for shipping heavy loads and running heavy equipment, and for rocket fuel.

Today these fuels are mostly made from natural gas or other nonrenewable fossil fuels via extremely inefficient reactions. While we think of it as a green fuel, most hydrogen gas today is made from natural gas.

Scientists are looking for ways to produce hydrogen and other fuels using renewable electricity. For example, it is possible to make hydrogen fuel by splitting water molecules using electricity. The key challenge is optimizing the process to make it efficient and economical. The potential payoff is enormous: inexhaustible, completely renewable energy.
