In a medium frying pan cook the green onions in 30g of the butter. Stir in the carrots and cook for 30 seconds. Stir in the ginger and the wine/stock. Once hot add the cream, salt and pepper. Cook, stirring frequently, over high heat until the sauce is reduced by half.
Stir in the scallops and cook for 1 minute. Add the remaining butter and stir until melted. Serve.
