SANDNES, Norway 20 February 2023 - Horisont Energi (EURONEXT: HRGI), a Norwegian
clean energy company, and Neptune Energy, an independent global E&P company,
have today signed a Memorandum of Understanding (MoU) with the international
energy major E.ON with the aim to develop a European CCS value chain.

Through this MoU Horisont Energi will strengthen the existing cooperation with
E.ON and by bringing in Errai partner Neptune Energy, Horisont Energi will
expand the cooperation towards a jointly development of a European carbon
capture and storage (CCS) value chain. The three energy companies will take a
strong position in the CCS market, accelerating the transition to carbon
neutrality. 

The MoU covers several areas such as the development, financing, and funding of
a complete value chain for CO2 handling. If Horisont Energi´s and Neptune
Energy´s application for CO2 exploration for the Errai project is awarded, the
intention is that this will be the first joint project.

-	"Our cooperation with E.ON and Neptune Energy is already strong. Through this
MoU we are expanding the cooperation to include three experienced energy
companies. Together we will strengthen our position to establish a European CCS
value-chain business. In case of license award of Errai, a possible direct
participation by E.ON would further strengthen the commercial basis for this
project", said Bjørgulf Haukelidsæter Eidesen, CEO at Horisont Energi.

Errai is planned as the first commercial CO2 project in Norway and will
represent an important step in industrialising carbon capture and storage (CCS)
as a competitive service. Bringing in E.ON will strongly contribute to linking
CO2 projects on the Norwegian Continental Shelf (NCS) with development of the
CO2 removal market in Europe. Pending legislative changes, the cooperation could
furthermore lead the way for commercial carbon removal market based on
sequestration of biogenic CO2. 

Several industries cannot be fully electrified and will therefore depend on CCS
to meet net zero emissions requirements and the fulfilment of the 1.5-degree
target by 2050. Such industries are situated across Europe and include
production of steel, cement, various chemicals, pulp, and paper. A full CCS
value-chain will bring the solution to the customers offering a one-stop-shop
for off-take of CO2 and permanent storage in safe sub-sea reservoirs. 

-	Neptune Energy's managing director in UK & Norway, Odin Estensen said "A
partnership with energy major E.ON will strengthen our ambition in establishing
Norway's first commercial carbon storage project. This could be a key
contributor to Neptune's 2030 goal of storing more carbon than is emitted from
our operations and from use of the oil and gas products we sell".

The Errai project was initiated by Horisont Energi in 2021. In December 2022
Horisont Energi and Neptune Energy submitted a joint application for the acreage
identified in the Errai project. In the application Neptune Energy has been
proposed as operator. 

The Errai project is planned with an injection capacity of 4-8 million tonnes of
CO2 annually in the first development phase, with potential for more in later
phases. The project includes an onshore terminal for intermediate CO2 storage
and processing, prior to transport for permanent storage in an offshore
reservoir.  

As a part of the work to further develop the project, Horisont Energi has
obtained a long-term lease option for a site suitable for a CO2 terminal at
Gismarvik in Rogaland. The landowner, Haugaland Næringspark, possesses one of
Norway's largest industrial areas, with critical infrastructure including access
to fibre, electricity, water, sewage, and a deep-sea quay already in place. 

In November 2022 Horisont Energi signed a letter of intent with E.ON concerning
for sequestration services of more than one million tonnes of CO2 planned to
originate from E. ON's European customer by 2030, starting from 2027 with
gradual increase. 

The three companies contemplate to cooperate as partners in different projects,
but in case of license award to Horisont Energi and Neptune Energy, Errai could
be the first possibility for E.ON to become a partner (subject to government
approval).  

The announcement of license award or not for ErraI to the applicants is expected
in the first half of 2023.
