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. 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. To assess and evaluate environmental impacts connected to SIP Power Gas, we conducted a Life Cycle Assessment (LCA) screening with aid from an independent third party. When developing a product with as little environmental impact as possible, all the steps in the supply chain need to be under evaluation. This means that every link in the process has been reviewed in detail to examine the environmental impact of each step. The ultimate goal is to deliver the strongest product possible, from a sustainability perspective.

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.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. Welcome to our complete collection of outdoor gear! We offer a wide range of products to help you make the most of your adventures in the great outdoors. Our product line includes:

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. 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. 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. Accessories: Complete your outdoor kit with our range of accessories, including fuel bottles, windshields, repair kits, and spare parts. 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.Primus have stated that their ultimate goal is to phase out fossil fuels altogether in the world of outdoor cooking. As such, SIP Power Gas is a major step forward, and will be a cornerstone product in the future Primus product range. After all, it’s the only consumable product they make, but also a core product, since it powers many of their camping stoves and lanterns. As I tend to go out alone, usually for just one or two nights, I'll typically default to the smallest and lightest canister-top stove. In comparison to these the Gravity is a bit of a beast, weighing a hefty 260g and taking up a lot more room in the bag. That said, its folding legs make it a smaller load than it could be, and it is certainly less onerous to carry than a typical multi-fuel stove. The Gravity is a lot of stove for a soloist, but it would make sense for a party of two, three or even four people. To compensate for its weight the unit is well made and durable, and although this is a short term test it looks like it'll offer years of service. In general, the production and distribution of camping stove fuel involve complex supply chains that can span multiple countries and companies. What is Primus SIP Power Gas? And how does it work?

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. 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. Our products are made in the best factories in the world. We know the factories personally and they have all signed up to our Code of Ethics in our supply chain. This includes the Ethical Trading Initiative base code, fair pay, safe working environments, no child labour, no modern slavery, no bribery or corruption, no materials from conflict zones and humane farming methods. 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. Verdict

The Swedish partner then sells the mix of biogas and fossil gas to customers who can technically fill that gas into their products. This 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.
