SANDNES, Norway 6 October 2022 - Horisont Energi (EURONEXT: HRGI) today
announced the signing of a project agreement with Neptune Energy to develop the
Errai Carbon Capture and Storage (CCS) project in Norway. 

The project agreement builds on the memorandum of understanding that was
announced on 30 August 2022. The partners are now setting up a project
organisation to progress the project.

"CCS is a key component of the decarbonisation of European industry, and we see
substantial interest in CO2 storage from European industry. Both partners share
a sense of urgency in realising this technology on a large scale, and we have
been able to move quickly to formalise this agreement. We look forward to
cooperating with Neptune in the years to come," said Bjørgulf Haukelidsæter
Eidesen, CEO of Horisont Energi. 

Errai plan to store 4-8 million tonnes of CO2 annually in the first development
phase, potentially storing more in later phases. The project includes an onshore
terminal for intermediate CO2 storage, with the intention to permanently store
the CO2 in an offshore reservoir. With the current plans the Errai project will
develop the second CO2 terminal in Norway.

The onshore terminal is designed to be capable of receiving CO2 from European
and domestic customers, including from the planned CO2 terminal at the Port of
Rotterdam. Several onshore locations in Southern Norway are being evaluated for
the terminal. 

The Errai project was initiated by Horisont Energi in 2021, and CO2 injections
are expected to start by 2026. With this important agreement with Neptune
Energy, Horisont Energi is now pursuing their second project development
following the flagship project Barents Blue.

Neptune Energy has reinjected CO2 in the K12-B gas field in the Dutch North Sea
for 14 years, as well as being a partner in the Norwegian Snøhvit field, which
has been reinjecting CO2 since 2008. Neptune aims to store more carbon than is
emitted from its operations and the use of its sold products globally by 2030.
