Alternatively, users may exchange empty cylinders for full. Fixed installations can be replenished by truck, with direct decant into the home installation. Delivering in liquid form concentrates the gas, providing the necessary yield to the device.īecause of their history of widespread adoption, LPG and Propane gas are universally available.
This is sought-after in high-energy applications, where the consuming appliance requires a high amount of energy. So-called “wet” valves allow the gas to leave the container in liquid form. The liquified gas is decompressed on exiting the containing cylinder or tank, consumed by its target appliance. LPG and propane have a 270x liquid to gas expansion ratio, increasing the volume of fuel held by a unit of space. Either way, the system works by reticulating gas from a local store to the appliances that need it.įor efficiency of storage, the gas is stored as a liquid.
#OFF THE GRID FEATURES PORTABLE#
Both LPG and Propane are available in smaller, portable cylinders. While natural gas is delivered through an underground grid, propane is stored in a self-contained tank. Yet, they are practical tools for going off-grid. Being fossil fuels, they are not usually listed with renewable sources like solar and hydro. Propane and Liquid Petroleum Gas (LPG) are well-known sources of industrial and domestic heating. That’s a lot of propane which is why the following power sources are so attractive. That means going through 80 twenty-pound propane tanks per year. propane tank holds 4.6 gallons of propane. If a regular house uses 10,000 kWh per year, you would need 370 gallons of propane per year. But our goal is to get moving toward something that provides much more energy for a far lower cost without relying on any fuel source.ġ gallon of propane generates 27 kWh. Apparently, it lasts pretty good and since we won’t be living there year-around, it’ll work for the time-being. The property came with a large upright propane tank similar to the one pictured above.
The workshop showed that technological advances will, in the future, provide essential contributions to the success of the off-grid energy access market.This is our large propane tank that’s currently providing power to our off-grid boat access cabin.Ĭurrently, the lion’s share of power to our off-grid, boat access cabin is propane. NAS or Redox flow still need more research to justify wider application. Application requirements and cost experience expectations were also taken into account, with the presentation concluding, that in the medium term, off-grid market Li-ion and modern lead acid (Gel and Tubular plates) will be most promising. Na-Ion. Professor Izael da Silva, head of the Strathmore Energy Research Centre (SERC) subsequently presented “Technological Advances in Storing Technologies for the Solar Off-Grid Market” on behalf of SERC and ISE Fraunhofer Institute. The features and different technical data were bench-marked in detail. New ultra-thin back-end solutions and new connector technologies are poised to lead to more design flexibility. Indeed, lower automation and more design flexibility require new innovative tools and processes within production. Robert very clearly showed the difference between Standard PV Modules and Off-Grid solutions. Lower cost transfer technologies like LPWAN (Low Power Wide Area Network), RDS (Radio Data Systems) or RF Remote seem to be of particular interest.įollowing on from this, Robert Händel of OPES Solutions spoke about “Customized Solar Application Modules – Requirements and New Ideas”. This was an excellent overview on Pay-as-you-go technology and showed some interesting outlooks for future innovations in data transfer. Victoria Arch of Angaza presented “Innovations in Data Transfer Mechanisms and Mobile Tools to optimize PAYG”. On Tuesday May 24, approximately 50 participants convened for a dedicated technology workshop.
