Different indicators used to describe the same form of green energy<\/h2>\n<\/div>\n\n\n\n

Madrid. 13 October 2026. <\/strong> A biomethane <\/a>plant can produce 1,000 Nm\u00b3\/h, generate 90 GWh a year, or form part of a market whose capacity is measured in bcm per year. These three figures can describe the same reality from different perspectives: flow rate, energy produced and gas volume. <\/p>\n\n\n\n

Understanding the units of measurement for biomethane is essential for comparing plants, interpreting energy targets or determining how much energy a given volume of gas contains<\/a>.<\/p>\n\n\n\n

The key concept is simple: m\u00b3 and Nm\u00b3 measure volume; Nm\u00b3\/h measures flow rate; kWh, MWh, GWh and TWh measure energy; MJ and GJ also measure energy; and bcm is used to express large volumes of gas.<\/p>\n\n\n\n

In Europe, these units are in constant use. The European Biogas Association (EBA), for example, estimated that by 2026 the continent\u2019s installed biomethane production capacity would stand at 8.2 bcm per year, having exceeded 8 bcm for the first time. <\/p>\n<\/div>\n<\/div>\n\n\n <\/div>\n <\/div>\n<\/section>\n\n

Volume, flow rate and energy: the fundamental difference<\/strong><\/h2>\n<\/div>\n\n\n\n
\n

Before converting units, you need to know what each figure represents. <\/p>\n\n\n\n

Volume <\/strong>answers the question: how much gas do we have? It can be expressed, for example, in cubic metres. <\/p>\n\n\n\n

Flow rate <\/strong>answers another question: how much gas flows or is produced per unit of time? Hence units such as Nm\u00b3\/h. <\/p>\n\n\n\n

Energy, for its part, indicates how much energy that gas contains and can be expressed in kWh, MWh, GWh, MJ or GJ. <\/p>\n\n\n\n

That is why 1,000 Nm\u00b3\/h and 100 GWh\/year<\/strong> are not directly comparable quantities. The first figure describes a rate of production; the second, the total amount of energy accumulated over the course of a year. <\/p>\n<\/div>\n<\/div>\n\n\n <\/div>\n <\/div>\n<\/section>\n\n
