Europe starts DME and LPG blend home heating trial

Dimeta is partnering with Delft University of Technology and The Green Village to trial the use of dimethyl ether (DME) with an LPG blend in home heating for the first time in Europe.

Renewable DME is a sustainable and clean fuel, used extensively in the chemical industry and as an aerosol propellant – and its application may negate costly retrofits or new appliances.

Extensive research and laboratory testing undertaken by Dimeta and various trade associations concluded that a 12% DME/LPG blend is safe and can be immediately blended without modification to infrastructure and equipment. However, it has yet to be trialled in a real-world home heating environment in Europe.

Located at Delft University of Technology’s The Green Village, this trial led by Dimeta will serve as a testing ground for a sustainable heating option for people in Europe living in off-grid, hard-to-decarbonise homes. The home will receive heat and hot water from a DME/LPG blend, using an off-the-shelf LPG boiler and cylinders.

The ability of DME to blend seamlessly into existing infrastructure can help expedite the transition towards cleaner energy sources. Further plans are underway to install space heaters and cooking appliances to test and demonstrate the versatility of DME as a fuel source.

DME can also be used as a pure fuel in 100% DME-dedicated appliances with modifications to supply chain infrastructure.

Dimeta’s project will gather user feedback on the performance of appliances and monitor the improvement of air quality by reducing noxious emissions as it moves beyond the laboratory setting and into real-world applications.

Stephen Hallett, Operations Director at Dimeta, said, “Developments regarding renewable and recycled carbon DME are among some of the most exciting in the global energy landscape, and for the 137 million people in Europe without a connection to the main gas grid, this will provide a pathway towards real decarbonisation options.”

Lidewij van Trigt, from The Green Village, said, “With this trial, not only the technical aspects of using a DME/LPG blend will be tested. Our field lab provides relevant test facilities where residents can provide their feedback and Dimeta is able to gain knowledge on how to apply this gas within the framework of Dutch legislation.”

Meanwhile Mitsubishi Heavy Industries (MHI) is exploring blending hydrogen with natural gas in Thailand.

Under a Memorandum of Understanding (MOU) with the Electricity Generating Authority of Thailand (EGAT), MHI will support the country’s aim of moving toward Net Zero emissions by 2065 as set out in Thailand’s Power Development Plan and Hydrogen Promotion Plan.

The agreement was signed at the sixth Japan-Thailand Energy Policy Dialogue (JTEPD), hosted at the Ministry of Economy, Trade and Industry (METI) in Tokyo.
