Chris Goggin reviews the operational and ecological benefits of using BioLPG and DME as an alternative fuel source for off-grid rural domiciles and businesses.
Rinnai hot water heating units and systems which are off-grid can be powered by LPG and BioLPG– a lower carbon intensive alternative source of fuel. Alternative energy is currently in demand due to recent developments in Ukraine that have radically altered the global energy landscape.
Current energy market conditions could potentially introduce further alternative fuel sources such as renewable biofuel Dimethyl ether (DME). Renewable DME is similar to LPG. R DME is a molecule-based fuel that can be produced through a wide range of renewable feedstocks which allows for quick and long-term sustainable production.
R DME combusts cleanly and releases no “soot” emissions. Dimethyl ether has many fuel properties that make it easily used in sites and appliances using heating oil. It has a very high cetane number, which is a measure of the fuel's ignitibility in compression ignition engines. The energy efficiency and power ratings of DME and heating oil engines are virtually the same. R DME is safe and reduces greenhouse gas emissions by up to 85% better improving local air quality.
Prior to this development LPG was the lowest carbon emitting source of fuel for the 15% of UK businesses and domiciles that function off-grid. BioLPG contains an almost identical chemical structure to LPG, meaning that a current Rinnai system is futureproofed and can accept either BioLPG or LPG.
BioLPGconsists of renewable materialsderived from a diverse mix of sustainable biological feedstocks and processes. Supported through cleaner sourced chemical ingredients BioLPGprovides huge benefits in carbon reductions and air quality, compared to traditional off-grid fuels such as heating oil.
BioLPG carries identical low NOx, SOx and PM as conventional LPG. NOx and SOx are acronyms relating to Nitrogen (NOx) and sulphur (SOx) oxide emissions which result from energy consumption and production that involves combustion. PM relates to particulate matter – solid matter and liquid droplets released by various chemical fluctuations generated through technology.
Each unit of energy produced for consumption is responsible for releasing a measurement of harmful carbon dioxide. Coal releases 100 units of carbon dioxide per unit of energy yielded; petrol and diesel produce 70 units - natural gases 50 units. BioLPGreleases noharmful emissions at all. DME performs to a higher standard when compared to heating oil, for instance PM emissions are virtually nullified.
As well as LPG and BioLPG, additional low carbon fuels are beginning to be produced, tested and approved for future and current use. DME has been tested extensively on vehicle use in Europe and North America. In one instance of testing a customer managed to operate 10 vehicles for 750,000 miles using DME as opposed to traditional vehicle fuels.
BioLPG is conceptually renewable and sustainable, as it is made from a blend of waste, residues, and sustainably sourced materials. BioLPG, can be described as an eco-propane, the chemical makeup of this gas is identical to LPG and is therefore compatible with existing in situLPG products from a combustion perspective.
In the BioLPGmanufacturing process, feedstocks undergo a series of complex treatments. They are combined with hydrogen in a process called hydrogenolysis which separates and purifies their energy content.
During the refining procedure, a variety of waste gases are produced that contain BioLPG. For every tonne of biodiesel, around 50 kg of BioLPGis produced from this gas stream. This co-product is then purified to make it identical to conventional propane.
LPG and BioLPG is the ideal solution for rural or off-grid commercial business use. An adaptation to BioLPG is simple and swift. New BioLPG units can be “dropped in.” A drop-in BioLPGis transmissible with existing LPG infrastructure, such as LPG storage tanks, water heating systems or any other existing LPG appliance. No expensive or intricate upgrades on current off-grid gas outlets are required to use BioLPG.
The transition to BioLPG will ensure businesses can continue to operate normally and efficiently with limited disruption ensuring minimum stress as no technical adjustments are required to your heating and hot water system. BioLPGcan be considereda convenient and non-intrusive minimum-carbon solution for off-grid businesses and homes.
BioLPG performance is indistinguishable from that of LPG. BioLPG provides instanton-demand heat and hot water without storage and limited adjustments required for use.
and the wider world have entered a new age in many respects, certainly so in terms of energy provision and security. Coupled with global decarbonisation targets and efforts, how separate nations provide domestic power and where this fuel is imported from has become a serious issue. BioLPG and other fuels like DME successfully navigate these ethical issues and deliver all suited power requirements.
BioLPG can be considered to maintain equal performance when compared to LPG, as DME can also be when measured against diesel. BioLPG is as easily purchased and utilized as LPG and helps create cleaner local air and helps meet international decarbonisation targets.

The Building Engineering Services Association (BESA) marked this year’s International Women in Engineering Day (INWED) by celebrating the important role played by women in the past, present and future of building services.
It featured a series of ‘guest blogs’ during the week of the 9th annual INWED that reflected the initiative’s 2022 theme of highlighting the inspirational work of women engineers globally to support “lives and livelihoods”.
In the world we are now living in it is extremely important to achieve Good Indoor Air Quality (IAQ) and all ventilation systems rely on the sensors to provide this information, so that an informed decision can be made on the buildings operation…...
