This time last year Air Liquide officially opened its first, large-scale biomethane production plant in the US.
A year on, and the plant located in Walnut, Mississippi, receives 350,000 metric tonnes of waste yearly, allowing it to inject biomethane into the network to heat 4,500 homes.
The biomethane plant purifies household waste gas provided by the landfill and converts it into a renewable gas that is reintroduced back into the energy grid to provide renewable energy for surrounding communities.
Air Liquide’s technologies convert biogas into biomethane for three main uses: the production of clean fuel, domestic use as a substitute for natural gas, and carbon-free hydrogen production.
In the US, biomethane is produced mainly by landfills, compared to in Europe where it mainly comes from farming biomass.
The industrial gas giant built a 6.5km pipeline to connect the production unit to the energy grid, illustrating the company’s ability to control entire value chain, from biomethane production to its distribution in natural gas networks.
In April 2018, the French industrial gas company announced it had doubled its global biomethane production capacity.
Air Liquide has announced the signing of two long-term supply agreements with Marathon Petroleum Company for a total of up to 900 tonnes per day (tpd) of oxygen for Marathon’s refineries in Texas City, Texas and Garyville, Louisiana.
Air Liquide has revealed the three winners of its 2018 Scientific Challenge.
