A method for operation of an industrial plant having an energy accumulator unit for production of synthetic natural gas, a power plant unit for production of electricity, an oxygen tank, a carbon dioxide tank and a water tank. In a first operation mode the energy accumulator unit is supplied with excessed electricity from the public grid to produce synthetic natural gas, wherein the produced synthetic natural gas is discharged in a gas network, while oxygen and water which are produced together with the synthetic natural gas are stored in the oxygen tank and the water tank correspondingly. In a second operation mode gas from the gas network together with oxygen from the oxygen tank and water from the water tank are used in the power plant unit to produce electricity, which is supplied to the public grid. This way electricity production excess is efficiently accumulated for industrial or municipal use.

Disclosed herein is a binder-free product and process for making the product. The product is a mechanically stable, water resistant torrefied biomass product that does not comprise an extrinsic binder additive. The product is made using a combination of appropriate pre-treatment steps and compressing the conditioned biomass feedstock into a thermally managed compaction device comprising at least one modified die. The modified die allows for differential cooling/heating modifications so as to control the temperature near the entrance to the compaction device and passing the formed torrefied biomass into a post-formation curing zone.
