Biomethane is seen by many as a vitally important part of our energy future, with various quarters keen to urge its long-term deployment. It’s part of a wider spectrum of renewable energies like biogas that are increasingly coming to the fore as the world strives for a more diversified and sustainable energy mix.
Though oil and gas prices have been the subject of much falling prices in the last two years, the previous trend towards higher natural gas prices, coupled with the demand for renewable energy, had been creating strong demand for the equipment to upgrade raw biogas to purified biomethane – and a number of industrial gas related companies are already involved in this embryonic space, particularly where the recovery and subsequent re-purposing of associated carbon dioxide (CO2) is concerned.
Today, there is a steadily growing trend for pure streams of biomethane to be injected into the mains gas grid (gas-to-grid) or used as a road fuel. With one cubic metre of biogas at 60% methane content converting to 6.7 kWh energy, according to bioeconomy consultants NNFCC, it is easy to see why.
