Damon Smith is accused of unlawfully and maliciously making or having in his possession an explosive substance with intent to endanger life or cause serious injury to property.
North Greenwich station was evacuated last Thursday during the alert.
Mr Smith, from south east London, was remanded in custody until 17 November.
The station was closed until 18:50, with disruption caused to the Jubilee line throughout the day.

Wilder's side were confirmed champions after rivals Oxford lost to Luton Town.
"He's a very down to earth guy, he's a motivator and certainly gets us going for games," said Richards.
"That hour before the game after we've warmed up he's certainly getting in each other's ears. It's loud in the dressing room, put it that way."
Richards continued to BBC Radio Northampton: "But you can go to him and speak to him, anything about football or outside football. He's been first class for all the players this season."
In November, the club owed repayments on a £10.25m loan to the local borough council, while they faced a winding-up petition from HM Revenue & Customs and the club's bank account was frozen.
However, after a takeover from Kelvin Thomas changed the fortunes of the club off the pitch and Wilder and his team continued their fine form to win 10 matches in a row, and they are currently on a 20-game unbeaten run.
Richards himself, though, has missed the run-in because of an Achilles injury, which needed an operation.
"I've had a tendon taken out of each Achilles, apparently you don't need them, and I've had a scrape on my Achilles to take away the scar tissue," said the 33-year-old.
"It'll be another week on my crutches, I should be back jogging within five weeks and then a week before pre-season starts I should be back to full fitness.
"The idea behind getting the operation done now was to make sure I was ready for next season. Maybe I could have battled on through the last few games, but I wouldn't have done myself or the club justice."

Phenytoin sodium capsules, used by 50,000 people in Britain, are made by Pfizer and sold by Flynn.
Pfizer said it was co-operating with the Competition and Markets Authority.
When Pfizer made the drug under its Epanutin brand name, the NHS spent about £2.3m on the drug, the CMA said.
This amount soared to £50m in 2013.
The CMA said Pfizer sold UK distribution rights to Flynn in 2012, but continued to make and supply the drug to the company.

This is a provisional report, with allegations made by the Competition and Markets Authority.  The companies now have a chance to give formal responses and a final ruling may not be made until next year.
But it comes at a time of intense debate about NHS finances, as patient demand and the cost of treatment rise faster than budget increases.  NHS England is grappling with the need for ambitious efficiency savings.  It has been under fire for reducing the number of treatments available to patients through the Cancer Drugs Fund.
So today's provisional findings, with renewed scrutiny of drug spending, are the last thing the pharmaceutical industry needs.
It was after this deal that prices rose, said the watchdog in a provisional finding.
"The CMA's findings on dominance and abuse are provisional and no conclusion can be drawn at this stage that there has, in fact, been any breach of competition law. We will carefully consider any representations from Pfizer and Flynn Pharma before deciding whether the law has been infringed.," said Ann Pope, CMA senior director of anti-trust enforcement.
Companies can be fined as much as 10% of annual sales for abusing a dominant position in a market, depending on the seriousness of the abuse.
Pfizer and Flynn can now supply their own views and evidence before the watchdog makes a decision, it said.
"Ensuring a sustainable supply of our products to UK patients is of paramount importance to Pfizer and was at the heart of our decision to divest the product," said Pfizer in a statement. "Pfizer is co-operating fully with the CMA's ongoing investigation."
A message left with Flynn Pharma was not immediately returned.
