Green methanol is a low carbon liquid chemical and fuel produced from sustainable biomass, often called bio-methanol, or from captured CO2 & hydrogen produced from renewable electricity, referred to as e-methanol. It is a multipurpose liquid which is easier to store and handle than green hydrogen. It's been slow to get much traction, but is showing promising signs of renewed interest with LEGO and others looking at its use in their operations. https://www.reuters.com/article/renewables-plastic-lego-novo-nordisk-idAFL8N36N1YN
