AAB Aberdeen International Inc

Aberdeen International Inc. (“Aberdeen” or the “Company”) (TSX: AAB F:A8H, OTC:AABVF) is pleased to share an update regarding its recent acquisition, AES-100 Inc., from T2M Global (see press releases dated February 1, 2021, February 11, 2021, March 3, 2021 and March 10, 2021, April 8, 2021).

AES-100 has been selected by US Department of Energy (DOE) to be deployed at Hawaii Gas in order to improve overall efficiency of Synthetic Natural Gas (SNG) production and the extraction of pure hydrogen (fuel-cell-ready) from a low-purity waste syngas stream. The expected benefits are (a) an improved cost of production of natural gas for Hawaii Gas; (b) a reduced carbon footprint; and (c) a new revenue stream from the sale of hydrogen into rapidly growing markets for low-carbon fuel and industrial uses.

President of T2M Global, Pinakin Patel, said “Hawaii has the highest electricity prices in the USA (30 to 40 cents/kWh). Recovering hydrogen from stranded dilute syngas can add millions of dollars in new revenue for Hawaii Gas and make it electricity-independent. It will also provide much needed hydrogen for a growing fleet of fuel-cell vehicles in Hawaii, as well as forklifts provided by Plug Power Inc.”

The project is expected to open a pathway for AES-100 to address worldwide dilute syngas-to-hydrogen market of over $50 billion: Hawaii Gas currently produces natural gas from the cracking of naphtha (an oil derivative); the natural gas is then consumed by over 1 million customers in heating, cooking, and energy applications. In the production of natural gas, there is a resulting low-purity hydrogen waste stream (syngas). Using the modular AES technology, which selectively separates high-purity hydrogen from this waste stream using an electrochemical process, Hawaii Gas will be able to create a new revenue stream, while concurrently improving the quality, energy, and emissions intensity of existing natural gas production.

The DOE-sponsored project is intended to prove AES-100’s capabilities as a scalable solution to not only improving plant efficiencies and carbon footprint - at a time when the energy sector is under growing pressure to decarbonize - but also pivoting product offerings towards the forecast $2.5 trillion hydrogen market.
