About this deal

For most of our stoves you will use gas as fuel. Our containers hold a mixture of propane, butane and isobutane. The mixture between the different gases depends on whether it is Power Gas, Winter Gas or Summer Gas. Through the principle of mass balance, every molecule of SIP Power Gas ensures the same amount of biogas made from food waste is produced.”

The figures show how positive the effects of this process can be: If such products are filled with biogas instead of fossil fuels, their CO2 emissions can decrease dramatically. All our factories sign up to our Code of Conduct. Find out where we make our product by visiting our Factories of Alpkit factory zone. Biogas, biodiesel, and other biofuels are substitutes for their fossil-fuel counterparts. Instead of pulling virgin materials out of the planet, biofuels leverage waste and residues from the food industry* that would otherwise end up in the landfill to make a biobased oil. The biobased oil is treated with hydrogen to produce hydrocarbons and is then refined into various products, such as gas or diesel. This will surely happen. However, to invest in a production line, the demand for biogas in camping gas canisters has to increase first.

The Future of Storage is Flow

Until then, we ensure that for every sold SIP Power Gas canister, the same amount of biogas is being produced and put into the market. We are carbon neutral under PAS2060 and offset our Scope 1, Scope 2 and Scope 3 operations and transport emissions. We recognise that offsetting is not part of the solution but a point to pass through on a journey to Net Zero. Carbon Neutral is just a step in that journey.

Different gases have different boiling points. The lower the boiling point, the higher the pressure in the container at a certain temperature, which leads to higher output on the stove. Propane has the lowest boiling point, followed by isobutane and then butane. At low temperatures, you want a mixture of gases that have a low boiling point as this results in better output on the stove. This is the reason behind the mixture of propane and isobutane in our Power Gas and Winter Gas. At higher outdoor temperatures, you want a mixture of gases with a higher boiling point instead, which is why we have butane instead of isobutane in our Summer Gas. For its clean burning and general convenience gas takes some beating as a fuel source for camping stoves. However it is not without disadvantages. In colder weather its performance can be sluggish at best, and if you're out in a UK winter or high up on an Alp this can be quite an issue. The cause is simple physics. Liquefied gas needs to evaporate before it's burned, but in the cold it is less able to do so. When the temperature outside decreases the pressure inside a gas canister also drops, and as the contents are used up this low pressure becomes progressively more of an issue. The brand has said that other steps on their sustainability journey will be to produce the most fuel-efficient stoves on the market, to carefully consider the choice of materials they use in future and aim to build stoves to be life-long companions (or in other words, achieve sustainability through longevity). In conjunction with offsetting the carbon emissions for all Primus fuel, it’s an ambitious and important programme that looks to a greener future. The Swedish partner then adds the same amount of biogas (coming from a Swedish biogas refinery) to its overall production. Primus is paying for the extra costs.

Some common types of camping stove fuels include propane, butane, isobutane and white gas. Yet, it is not only the products and their raw materials themselves that leave a strong ecological footprint but also their supply chains. Camping stove fuel can be produced in various locations worldwide, depending on the fuel type. The Swedish partner then sells the mix of biogas and fossil gas to customers who can technically fill that gas into their products.

We have joined the Science Based Targets Initiative which sets independent targets for us to achieve to do our bit to limit global warming to 1.5°C. Our targets are to halve our Scope 1 and Scope 2 emissions by 2025 based on 2018 base year and reduce our total carbon intesnity by 15% every year to achieve genuine net zero by 2050.While we traditionally have sourced our gas from South Korea, we have moved the production for SIP Power Gas to Greece to be closer to our main customer base. From there, the gas is now being transported to Northern Germany and then to Sweden – a significant shortening of the delivery routes. The reason that production was not moved directly to Northern Europe is that there is currently no infrastructure in Sweden or Germany to fill biogas into camping gas containers in these countries. Our goal is to deliver the strongest product possible, from a sustainability perspective. When we move production of SIP Power Gas closer to our largest markets, we decrease the distance the fuel is transported. This results in a significate reduction of the canisters' climate impact than regular Primus Power Gas.

Currently, no studies have measured the exact environmental impact of outdoor stove fuel. However, since oil and gas are considered non-renewable resources, their production and use have various ecological, social, and economic effects. SIP Power Gas is also EKOenergy-labelled. EKOenergy is a global, non-profit and independent mark of quality, supported by environmental NGOs. To achieve this labelling a product must fulfil strict sustainability criteria. In turn, the label also finances renewable energy projects in developing countries. In this way, buying EKOenergy-labelled products allows consumers to contribute to the fight against energy poverty and climate change. Construction and PerformanceThis is the first step in our journey of providing a more sustainable stove fuel. Although this model does not include filling our SIP Power Gas canisters with “green molecules,” we have taken one major step – we have secured and supported production of biogas. In terms of performance, SIP Power Gas is a propane/butane mix. This differs slightly to standard red Power Gas, which is a propane/isobutane mix. There’s not much difference between the two, as isobutane has an identical molecular structure to butane. However, it is slightly more efficient when used as a cooking fuel in lower temperatures, so gas canisters containing isobutane rather than butane are generally considered to offer slightly superior performance in colder weather. However, most campers won’t notice a significant difference, and the environmental benefits of SIP Power Gas over other gas canisters on the market means this is a small but worthwhile sacrifice.
