Natural gas is often referred to as a ‘bridge’ fuel? What is meant by this, and is this moniker valid?
Natural gas advocates characterize it as a bridge fuel. The implication is that we will use it now, to achieve short-term greenhouse gas reductions by replacing coal-fired power, then reduce or end reliance on natural gas over some time period to lock in long-term greenhouse gas reductions. While at first glance this makes sense but overtime due to leakage the new coal fired plants. There are some periods in the next 30 years when gas will result in more climate impact than new coal plants. If leakage is higher than 4 percent, there are some periods when gas will be worse for the climate than existing coal plants.
