Yes according to the latest IPCC report ( http://www.ipcc.ch/report/sr15/ ) in the 1.5 degree scenario we need to deploy bio-energy combined with carbon capture storage on large scale. Carbon removal tech will become indispensable and is definitely part of "Plan A".

Some scenerios rely more on bioenergy with carbon capture and storage, while others rely more on afforestation, which are the two carbon-removal methods most often included in the IPCC reports. Trade-offs with other sustainability objectives occur mostly through increased land, energy, water and investment demand.

There is another scenario were we might not need a lot of bioenergy with carbon capture storage and that would be if we would decorbonise at an incredible fast rate (starting now) and planted a lot of trees. I'm not seeing that happening anytime soon though.
