Energy Digital takes a look at liquefied natural gas (LNG) and the organisations that are producing and distributing it in the fast-growing industry.

With global energy demand expected to grow by a further 18% by 2035, over the coming decades liquefied natural gas (LNG) is predicted to be a fast-growing fossil fuel of choice due to its vast quantity, lesser environmental impacts over coal and oil, versatility and safety. LNG trade increased from 100mn tonnes in 2000 to nearly 300mn tonnes in 2017.

LNG is the liquification process of natural gas – extracted from beneath the earth’s crust –predominantly comprised of methane. The natural gas is cooled to -162°C (-260°F) in order to liquify it and, as a result, occupy 600 times less space., This makes long distance and overseas transportation easier and more economical. Once transportation is complete, LNG goes through a regasification process for distribution.

 

Why countries are turning to LNG

LNG currently is a vastly untapped resource; the US alone has an estimated 2,384trnn cubic feet of recoverable resources (2013). When burned, natural gas produces 45% less carbon dioxide than coal, 30% less than oil, and 15% less than wood, making LNG a preferred environmental alternative. It is estimated that if LNG was used to displace coal in China it would reduce CO2 emissions by 60 to 90mn tonnes per year.

LNG has enough horsepower to be used by industrial, commercial and residential users, and can be compressed to form compressed natural gas (CNG) to allow natural gas usage in vehicles such as Ford’s new model, Ford Aspire. Compared with other fossil fuels, LNG is a much safer option. When exposed to a source of heat, LNG will vaporise back into a natural gas leaving no residue behind, as well as only being flammable when there is a gas-to-air concentration of 5-15%.

While LNG is less environmentally impactful than more traditional fossil fuels, over the long-term it is not a fix for current environmental conditions. LNG is not a renewable resource like wind and solar power; it is still a fossil fuel that will eventually run out, and still produces CO2 when it is burnt for heat or electricity by consumers. Additionally, within its own value chain, LNG requires high amounts of energy during liquefaction and regasification, resulting in the production of GHG emissions in the periphery of the gas itself.

Nevertheless, LNG is still a better alternative to coal, nuclear and oil for reasons of GHG emissions, safety and abundance. Therefore, short-term LNG is being used by companies such as NRG Energy and Origin Energy are to repower their plants with LNG so that, in the long-term, companies can naturally retire their current plants and replace them with renewable alternatives.

 

Who is currently providing and distributing LNG?

- LNG Canada

Formed in 2018 with support from the First Nations group, all levels of government, business, labour and the community, LNG Canada is a joint venture (JV) between Shell, Petronas, PetroChina, Mitsubishi Corporation and Korea Gas Corporation (KOGAS). Its export facilities are based in Kitimat (British Columbia), the second largest reserve in Canada that is also close to Asian markets for LNG Canada to export to. From the beginning, LNG Canada has had safety, economic, environmental and community interests at the forefront of its strategy to put Canada on the map for LNG exportation.

What will the new LNG Canada facility do?

  • LNG processing units – Carbon dioxide, water, condensate, sulphur and other impurities will be removed, followed by being chilled to approximately -162°C to turn the gas into LNG. The units have the capacity to produce 14mn tonnes per year.
  • Storage tanks, loading lines and marine terminals – Processed LNG will be piped to storage tanks until ready for loading on LNG carriers at the Wharf. To accommodate this two LNG loading lines will transfer the LNG to the Wharf and LNG carriers. In addition, an existing wharf will be redesigned to hold up to two LNG carriers at a time.
  • Rail yard – Inside the facility, a railyard will be connected to an existing system to load and transport condensate (a petroleum liquid) for sale to customers.
  • Water treatment facility – Water will be drawn from the Kitimat River to be used for predominately cooling and drinking. Water taken will be treated as needed and reused in a closed loop system to reduce water loss.
  • Flare stacks – Acting as a safety device, two flare stacks – one 60m tall and the other standing at 125m – will be installed. When operating normally, a three-metre clean burning pilot light flame will be at the top of the stack.
  • Workforce accommodation – To limit the impact of an influx of people at Kitimat, LNG Canada is building a workforce accommodation centre called Cedar Valley Lodge that can hold up to 7,500 people.

 

- Royal Dutch Shell

Established in 1907, Shell operates in over 70 countries, and is currently diversifying its offering to provide cleaner energy solutions in line with increasing demands for sustainable energy.

Shell has been a developer of LNG for over 50 years. Over those years, Shell has been involved with many LNG project including the first LNG liquefaction plant, established in 1964. Today, Shell is developing a Floating LNG (FLNG) production facility in order to gain access to resources underwater.

Shell is involved with every stage of the LNG value chain and has access to over 40mn tonnes of regasification capacity, 13 liquification plants, and operates 20% of the world’s LNG shipping with nearly 100 carriers.

Countries that Shell provide LNG to include: Japan, Korea, Spain, France, Italy, Turkey, Mexico, the US, Asia and Australia. This is along with supply projects in the West Pacific, Nigeria, Australia, Oman, Qatar, Russia, South Caribbean, Peru, Egypt, UK and India. In 2018, Shell sold a total of 71mn tonnes of LNG.

- Korea Gas Corporation (KOGAS)

Incorporated by the Korean government in 1983, KOGAS is one of the world’s largest importers and distributors of LNG, and is the nation’s sole provider. Currently, KOGAS has 17 power generation plants and 10 power generation companies supplying LNG to Korea. The company operates  four LNG terminals and a nationwide pipeline network to supply the imports from around the world to power generation plants, gas-utility companies and city gas companies throughout Korea.

To provide a stable supply of LNG volume to the nation, KOGAS has invested in numerous LNG research and development, exploration, production, distribution and compression projects.

Startup Form Energy receives $200 million Series D financing round led by ArcelorMittal’s XCarb innovation fund to further develop iron-air batteries

Form Energy believes it has cracked the conundrum of commercialising grid storage through iron-air batteries - and some of the biggest names in industry are backing its potential.

The startup recently announced the battery chemistry of its first commercial product and a $200 million Series D financing round led by ArcelorMittal’s XCarb innovation fund. Founded in 2017, Form Energy is backed by investors Eni Next LLC, MIT’s The Engine, Breakthrough Energy Ventures, Prelude Ventures, Capricorn Investment Group and Macquarie Capital.

While solar and wind resources are the lowest marginal cost sources of electricity, the grid faces a challenge: how to manage the multi-day variability of renewable energy, even in periods of multi-day weather events, without sacrificing energy reliability or affordability.

Moreover, while Lithium-ion batteries are well suited to fast bursts of energy production, they run out of energy after just a few hours. Iron-air batteries, however, are predicted to have theoretical energy densities of more than 1,200 Wh/kg according to Renaissance of the iron-air battery (phys.org)

The active components of Form Energy's iron-air battery system are some of the cheapest, and most abundant materials: iron, water, and air. Iron-air batteries are the best solution to balance the multi-day variability of renewable energy due to their extremely low cost, safety, durability, and global scalability.

It claims its first commercial product is a rechargeable iron-air battery capable of delivering electricity for 100 hours at system costs competitive with conventional power plants and at less than 1/10th the cost of lithium-ion and can be optimised to store electricity for 100 hours at system costs competitive with legacy power plants.

"This product is our first step to tackling the biggest barrier to deep decarbonisation: making renewable energy available when and where it’s needed, even during multiple days of extreme weather, grid outages, or periods of low renewable generation," it states.

Mateo Jaramillo, CEO and Co-founder of Form Energy, said it conducted a broad review of available technologies and has reinvented the iron-air battery to optimise it for multi-day energy storage for the electric grid. "With this technology, we are tackling the biggest barrier to deep decarbonization: making renewable energy available when and where it’s needed, even during multiple days of extreme weather or grid outages," he said.

Form Energy and ArcelorMittal are working jointly on the development of iron materials which ArcelorMittal would non-exclusively supply for Form’s battery systems. Form Energy intends to source the iron domestically and manufacture the battery systems near where they will be sited. Form Energy’s first project is with Minnesota-based utility Great River Energy, located near the heart of the American Iron Range.

Greg Ludkovsky, Global Head of Research and Development at ArcelorMittal, believes Form Energy is at the leading edge of developments in the long-duration, grid-scale battery storage space. "The multi-day energy storage technology they have developed holds exciting potential to overcome the issue of intermittent supply of renewable energy."

Investors in Form Energy's November 2020 round included Energy Impact Partners, NGP Energy Technology Partners III, and Temasek.

In May 2020, it signed a contract with Minnesota-based utility Great River Energy to jointly deploy a 1MW / 150MWh pilot project to be located in Cambridge, MN. Great River Energy is Minnesota's second-largest electric utility and the fifth largest generation and transmission cooperative in the US.

Last week Helena and Energy Vault announced a strategic partnership to identify additional opportunities for Energy Vault’s waste remediation technologies as the company begins deployment of its energy storage system worldwide. It received new investment from Saudi Aramco Energy Ventures (SAEV) in June.

Maoneng has revealed more details of its proposed 240MWp / 480MWh Battery Energy Storage System (BESS) on Victoria’s Mornington Peninsula in Australia (click here).

The BESS represents hundreds of millions of dollars of investment that will improve electricity grid reliability and network stability by drawing energy from the grid during off-peak periods for battery storage, and dispatching energy to the grid during peak periods.
