Remco Krul, marketing & communications manager at Nordsol, explained the company’s Bio-LNG installations, and how biogas producers can tap into this profitability potential as CHP permits expire.
The main components in biogas are methane (CH4) and carbon dioxide (CO2). To produce bio-LNG, the methane in the biogas is separated from the carbon dioxide and contaminants to produce biomethane. This biomethane is then liquefied. The liquefaction process increases the energy density 600 times and makes the biofuel ideal for heavy-duty and maritime transport.
Bio-LNG is similar to LNG as both fuels are composed of methane. Bio-LNG and LNG can be blended in any ratio. The most important difference between the two fuels is the source of the methane. LNG is made from natural gas while bio-LNG is made from biogas. This makes bio-LNG a renewable fuel.
It is expected that by 2050, long-haul road and maritime transport will use a mix of bio-LNG, other biofuels, hydrogen-derived fuels and electricity. However, most of these fuels are still in research phase and not available at commercial scale. And today's batteries cannot store the amount of energy needed to...
