In Powerzeek we focus on providing services which makes it easy for ship owners and truck owners to find, buy and use clean energy. We launched the Powerzeek Energy Platform in 2020, and below is a list of the type of cleaner energy products we have added to the platform so far.
Green LNG is a carbon-free energy product where the calculated CO2 emissions from burning natural gas is offset through carbon offsets and/or Renewable Gas Guarantees of Origin (RGGOs).
LNG is natural gas cooled down to -162 degrees Celsius (-260 degrees Fahrenheit). By cooling down the gas to this temperature the volume is compressed 600 times, thereby allowing a large volume of energy to be stored in a much smaller space.
LNG is regarded one of the most promising energy products for the shipping sector, contributing in reduced emissions of CO2, NOx, SOx and particles.
Upgraded biogas, also often called biomethane, can be compressed either in high pressure as compressed biogas (CBG) or as liquid biogas (LBG/bio-LNG). Biogas is a fossil-free and 100% renewable energy product. The gas can be produced from waste, sewage and other biodegradable materials. The use of biogas emits close to zero oxides of nitrogen (NOx) and sulfur oxides (SOx), and no particulate matter (PM). This contributes to cleaner air, especially for inhabitants living close to the sea and busy ports.
As an energy product, LBG is interchangeable with LNG, as they both consist mainly of methane (CH4). This means that the two gases can be mixed.
