Get Price2 天前 · Over the next decade, gas arriving in Europe may be characterised by a wider range of gas quality. This could mean gas in continental Europe may in future be less compatible with Britain’s gas quality standards. It may be necessary to take action to alter the gas quality before continental gas can be accepted onto Britain’s gas network.
