The use of fossil fuels for indirect combustion. Also the use of liquid biofuels for indirect combustion, unless they meet certain criteria.

Proposed Regulation on the Prohibition of the Use of Fossil Fuels for Indirect Combustion in the Industry from 2030

The proposed regulation establishes a national prohibition of the use of fossil fuels for indirect combustion in industries not covered by § 1-3 of the Norwegian Emissions Trading Regulation. The proposed regulation also establishes a national prohibition of the use liquid biofuels for indirect combustion in industries not covered by § 1-3 of the Emissions Trading Regulation, unless land-use criteria and emission reduction requirements equivalent to those set out in §§ 3-6 to 3-9 of the Norwgian Product Regulation are met. It is proposed that the prohibition shall enter into force on January 1st 2030, whilst the rest of the regulation, is proposed to enter into force on 1 January 2029 (except for § 7 regarding administrative fine). The regulation will not be adopted until after the notification process is completed.

For the purposes of the proposed regulation, "the industry" equals all commercial activities falling under the industry codes (NACE) 05, 07, 08, 09.9, 10–33, and 35.3.
Indirect combustion is combustion where the energy from the fuel, in the form of heat, steam, mechanical power, or electricity, is used in industrial processes involving heating, drying, or other treatment of objects or materials, without the flame or gases being in direct contact with these.
The following use of fossil fuels and liquid biofuels in the industry are exempt from the prohibitions mentioned above:
a) Combustion of waste gas from industrial processes
b) Combusition required for start-up and shutdown
c) Required auxiliary combustion in facilities covered by Chapter 10 of the Waste Regulation
d) Combustion of own movable property and substances that, pursuant to § 27 of the Pollution Control Act, are considered waste
e) Combustion of residual or waste gas after refining or processing, with or without hydrogen
f) Mobile machinery, equipment, and required use of fossil fuels in emergency power generators
The prohibitions will not apply in the event of an interruption in power supply, until the supply is restored. Furhermore, the prohibitions will not apply in the event of faults or damage that prevent the use of other energy carriers in industrial processes. In the latter case, the use of fossil fuels shall then be limited to the time required to repair such faults or damage without undue delay.
If an enterprise cannot comply with the prohibition due to it being operationally unfeasible to connect increased electricity consumption to the power grid by January 1 2030, a time-limited exemption from the prohibition may be granted, upon application. The enterprise must provide documentation from the grid operator confirming that connection cannot be made within the deadline. Exemptions from the prohibitions may be granted if it is deemed necessary to safeguard national security interests or in other exceptional cases.
The proposed regulation establish that, in case of a violation of the prohibition, the responsible for the violation may be subject to an administrative fine pursuant to Section 80 of the Norwegian Pollution Control Act.
