![]() The leftover gaseous mixture, aka crude helium (75-80% He), is later put under lower temperatures to remove the nitrogen, leaving ‘Grade A’ helium (99.99% He). Then, the liquid natural gas is separated and returned to its gaseous state to be sold as fuel. At -250☏, all the gas liquefies, except nitrogen and helium. Helium extraction essentially consists of exposing natural gas to high pressures leading to a temperature drop and subsequent liquefaction of the gas. As helium prices have doubled prices in the last 10 years, helium is now worth 40 times LNG (liquefied natural gas). A natural gas deposit with just 0.3% He in is enough to make helium the most valuable component. ![]() Helium is primarily extracted as a byproduct in natural gas wells. a byproduct of natural gas, a significant reduction in their helium production is presumed by the recent collapse of oil and gas prices. Since helium extraction in both countries is secondary, i.e. Similarly, Algeria is subject to political instability. Qatar’s supply is somewhat vulnerable due to conflicts with Saudi Arabia that caused several shutdowns in its industry. Helium projects in Qatar and Algeria, however, are afflicted by geopolitical uncertainty. Processing plants in the US (source: USGS) The two most prominent US sources of helium are the Hugoton-Panhandle complex, in Texas, Oklahoma, and Kansas, which is connected to the Helium Pipeline and the Bush Dome Reservoir (the BLM system), and ExxonMobil’s Riley Ridge Field, in southwestern Wyoming (Figure 2). The US is the largest producer (~ 40 %), followed by Qatar (~ 30 %) and Algeria (15-20 %). Estimated consumption of helium in the US (source: USGS Mineral Commodity Summaries 2019) Currently Producing Helium ReservoirsĪccording to the USGS, the total estimate of global helium reserves in 2018 was 51.9 billion cubic meters. The gas is also applied to inflate aircraft as dirigibles (blimps), conduct analytical and laboratory analyses, welding, leak detection, and hard drive and semiconductor manufacturing. It is dominantly used as a coolant in low-temperature systems, such as in superconductive devices like magnetic resonance imaging (MRI) machines. Aside from its most famous uses as a balloon filling (Figure 2), helium plays a crucial role in many industries (Figure 1). For some of its functions, there is few or no suitable replacement for helium. Helium has unique properties that make it a key commodity in several applications. ![]() The first, an overview of the helium commodity, is available here. This article is the second in a series about helium mining. This means now could be a good time to start thinking about investing in helium. The liquidation of the US federal helium reserve by 2021 adds to the threat of a steady helium crisis. In the past years, recurrent concerns about helium shortages have become more and more common. It is so light that it simply floats away. Reports in July 2022 revealed that Helium had falsely claimed Lime and Salesforce as two of their major customers for years, despite neither company having a formal relationship with Helium or using the network.Although helium is quite abundant in the universe, it is rather scarce here on Earth. and raised $200 million in a funding round led by Tiger Global Management and Andreessen Horowitz. Hotspot operators would also have a vote in the operation of the network. These individually owned nodes are purchased at costs of up to $500 each, and the payments to owners vary based on data usage but can be as low as $.10 a month. In 2017, the company's funds were running low, so it switched to a new strategy: offering individuals payment in cryptocurrency to operate individually owned nodes in their homes or offices. in 2013 as a network of LoRa gateway hotspots which could be deployed throughout an area by agreements with building owners, typically paid in conventional currency. The Helium Network was begun by Helium, Inc. The network aims to provide connectivity to IoT sensor devices in areas where wireless or mobile coverage is minimal, or requires too much power. Nodes on the network are generally owned and placed by individuals in their homes or offices, and they are rewarded for their participation in the network in payments of HNT. The Helium Network is a decentralized wireless Internet of Things (IoT) network using the LoRaWAN system, tied to the cryptocurrency Helium Network Token (symbol HNT).
