Energi -og miljøkomiteen inviterer til høring på karbonlagringsprosjektet CCS-Northern Lights “Langskip” 3. november 2020, samme dag som presidentvalget i USA. Dette virker som myndighetenes taktikk for å gå under radaren med et kostbart og ødeleggende industriprosjekt. Norges Miljøvernforbund (NMF) krever at høringsdatoen utsettes.
Stortingsmeldingen Meld. St. 33 (2019-2020) er ikke god nok som beslutningsgrunnlag om igangsetting. Det mangler LCA (Life Cycle Assessment/Livsløpsanalyse), dvs. regnskap på energibruk og klimautslipp i anleggsperioden og i drift.
Dette må utredes og presenteres på en ny høring før beslutning kan tas.
Better alternatives to CCS
The Norwegian Environmental Protection Association believes that there are better, cheaper and more effective climate measures than CCS/artificial carbon storage. The solution is to reduce the amount of waste, sort plastics at source, take out organic waste and use it for compost or bio-oil. Cement production can be greatly reduced, as there are good substitutes for concrete from waste (iron and glass) that do not require huge amounts of energy in production.
The Norwegian Environmental Protection Association (NMF) believes that there is a general weakness in Stortingsmelding 33 (2019-2020). There is a lack of a full LCA (Life Cycle Analysis) on the project. The LCA must include all resource use and pollution/climate footprint and natural footprint from cradle to grave. NMF requires an exhaustive, openly available LCA that includes the entire burden from the construction and operation of the CCS facilities.
This may apply to extraction of metals/mining, fuel consumption, greenhouse gas emissions associated with construction work, use of concrete for production facilities and warehouses. Infrastructure for the construction of pipelines, energy consumption and greenhouse gas emissions associated with capture, cooling, storage, transport by car, reloading, transport by ship and pumping to reservoirs. In addition, all emissions associated with the drilling of new wells, uncertainty factors such as faulty drilling, collapse in the drill string etc. must be entered.
Furthermore, the construction of ships must be factored in with full LCA from mining to smelting of steel, processing and construction of the ships, as well as transport costs in CO2 emissions in addition to methane emissions, NOx and SOx. If it is calculated to use battery-powered ships, the entire climate burden from mining and construction of the battery packs must be factored in.
Hydrogen production requires too much energy, and gives little in return
NMF believes that hydrogen production as an alternative is not advisable, as it requires large amounts of energy for production. Hydrogen delivers only 30% compared to the input of energy in production,
If the energy comes from electricity production from, for example, offshore wind with an average effect of 36.5%, we will be left with 10% of the amount of energy compared to the installed effect of the wind turbines. We note that the drilling of a well has been calculated for start-up, but we expect that the cost will be far higher than what is presented in St.m33. There are several uncertainty factors associated with CCS: Costs during construction, where the costs easily may exceed what is budgeted and allocated. There is a risk that CCS will be unreasonably expensive to implement.
There is great uncertainty related to the risk of earthquakes. An increase in pressure in a reservoir can lead to earthquakes as a result of slippage/movement of the reservoirs.
Uncertainty regarding leakage of CO2 from the reservoirs.
We share Equinor's concern regarding the risk of leakage from the reservoirs.
Prediction of CO2 leakage from large CO2 stores https://ife.no/prosjekt/forutsigelse-av-co2-lekkasje-fra-store-co2-lagre/
The project under the auspices of Ife (Department of Energy Engineering) will investigate mechanisms for CO2 leakage from large CO2 stores in aquifers and reservoirs. CO2 is lighter than water and it is held in place in the reservoir by thick layers of dense sediments. Leakage through these dense sediments may be possible due to the formation of so-called "chimney" or pipe structures. These pipe structures (chimneys) are today observed in most sedimentary basins due to improved seismic observations. It is important to understand leakage through pipe structures with regard to the stability and safety of a CO2 reservoir over a long period of time. Source: Ife
In the summary from the OED, emphasis is placed on the fact that other solutions can be found to reduce greenhouse gas emissions. NMF has suggestions for good alternatives to make CCS redundant:
Natural carbon stock is better than artificial.
The Norwegian Environmental Protection Association believes that it is more important and easier to take care of nature's own carbon store. Forests and especially bogs store large amounts of carbon. Peat bogs are the largest natural carbon store on earth; the area covered by near-natural peatland worldwide (> 3 million km2) stores 0.37 gigatonnes of carbon dioxide (CO2) a year – and stores more carbon than all other vegetation types in the world combined.

Source sorting and reduction in plastic production and waste incineration is a better and more sustainable solution than increasing waste incineration. Minimization of waste incineration, source sorters with fewer fractions of plastic. Phase out fossil plastics.
Source sorting of plastic and organic waste is better than CCS
It is better to sort organic waste, food waste can be used for composting and soil improvement and will increase the binding of CO2. Organic waste must not be burned in incinerators, but used for e.g. composting or bio-oils (Carbon-neutral/0-emission fuel).
Fjernvarme fra avfallsforbrenning kan stoppes, det er 0-utslipp i varmebrønner på 1500 m dyp som holder 20 grader, der vann pumpes opp for oppvarming av bygninger med lite naturbeslag/10 m2. Tilsvarened vil 20-25 varmebrønner på 250m dyp kreve 4000 m2 areal.
Reduce the production of cement
Norge bør arbeide for å minske bruken av sement, og finne alternative byggematerialer som kan erstatte tradisjonell sement/betong (Portlandsement). Sementproduksjon har et enormt energibehov som krever høy forbrenningstemperatur og som gir store CO2-utslipp. CCS forutsetter høyt materialforbruk og energiforbruk.

CCS is closely linked to waste incineration and cement production. Norway must become better at reusing materials and reducing the consumption of new materials, there will be preventive activities that reduce the climate footprint, material use, energy use and nature footprint. Today, huge quantities of concrete are used in road projects and in the wind power industry. There are better, more reasonable and secure solutions that are not a technological solution to a problem.
The conclusion is that we manage without CCS.
