Vast Solar Becomes Vast

Australian renewable energy company Vast is proud to announce its rebrand, effective from 8th May.

The new brand identity is expected to better communicate Vast’s position in the market and improve its visibility among stakeholders.

Vast’s target markets have broadened from initially focusing on dispatchable renewable electricity to now include process heat for industrial uses, as well as combinations of renewable electricity and heat to power green fuel refineries producing zero emissions methanol for sustainable shipping and aviation fuel.

As part of the rebranding initiative, the company's website, social media accounts, and other marketing materials will be updated with the new brand identity. This will include transferring Vast’s website to www.vast.energy, with the www.vastsolar.com site and all existing pages redirected to this domain.

Vast’s rebrand follows the recent announcement of a business combination agreement with Nabors EnergyTransition Corp. (NETC). The combined entity would be named Vast and is expected to be listed on the New York Stock Exchange (NYSE) under the ticker symbol “VSTE” while remaining headquartered in Australia.

Vast’s proprietary concentrated solar thermal power (CSP) technology has received significant support from the Australian government. Most recently, the Australian Renewable Energy Agency (ARENA) approved up to $65 million in funding to Vast to construct VS1, a first-of-a-kind 30 MW / 288 MWh CSP plant in Port Augusta, South Australia.

VS1 will be co-located with SM1, a world-first green methanol demonstration plant, which in February was selected to receive AUD$19.48m and EUR13.2m from a collaboration between the Australian and German Governments. SM1 will take zero emissions dispatchable electricity and heat from VS1 to produce green methanol for sustainable shipping and aviation fuel.

Vast’s CEO, Craig Wood said, "We are excited to embark on this new chapter for Vast. Our new brand identity reflects our continued growth and, following our anticipated merger with NETC, we are confident this new brand will support our company in deploying our world-leading renewable technology in markets around the world."

About Vast

Vast is a world-leading renewable energy company that has developed CSP systems to generate, store and dispatch carbon free, utility-scale electricity, industrial heat, to enable the production of green fuels.

Its “CSP v3.0” system is easier to permit, build and maintain than larger central tower CSP systems, and is more efficient. Vast is proud to enable and help drive the change that we all need now – access to affordable, reliable, renewable electricity and heat. Visit www.vast.energy for more information.
