No. Any CO2 released when these fuels are burned has to come from the algae. The algae gets it from the air. So CO2 is cycled, but not added to the atmosphere.

For my understanding, the problem with the fossil fuels is that they are trapped in the ground and we are releasing the carbon that was trapped in the ground into the atmosphere.

That is true for fossil fuels. But for oil produced from algae, the carbon came from the atmosphere or the immediate surface environment, so it's not introducing any "new" (or long-sequestered) carbon.
