Vattenfall to build 150 MW ‘e-boiler’ in Amsterdam

Vattenfall will build a 150 MW ‘Power-to-Heat’ e-boiler at its facility in Diemen, Amsterdam.

The company has been granted a permit and a Dutch SDE++ subsidy to build the boiler, which is believed to be the largest in Europe and can be put into use in 2024.

“We are very glad to have been awarded both the permit and the SDE++ subsidy for building a large 150 MW e-boiler at Diemen,” said Ulrika Jardfelt, head of business area heat at Vattenfall.

“Vattenfall wants to supply 100% sustainable heat in the Amsterdam region by 2040. In addition to e-boilers, Vattenfall is, therefore, also working on a number of other sustainable heat sources, such as biomass, geothermal, data centre heating, and aqua-thermal heat.”

The Dutch SDE++ scheme provides subsidies for the use of techniques for the generation of renewable energy and other CO2 reducing techniques. Subsidies are awarded over 12-15 years, depending on the technology.

The e-boiler is similar to a ‘kettle’, according to Vattenfall. The installation converts electricity into hot water, which can be supplied to households and companies or that can be stored in the already present heat buffer, a large ‘thermal flask’.

“The e-boiler only switches on if the electricity mix is sustainable with a lot of electricity from solar and wind,” said Alexander van Ofwegen, director of heat at Vattenfall Netherlands.

“When there is insufficient green energy, the gas-fired power plants in Diemen are still needed to produce electricity – power plants that also supply heat very efficiently. We expect that these gas-fired plants will remain necessary in the coming decades for security of supply in the Netherlands; first on natural gas, but later hydrogen from renewable sources.”

With the current expected deployment of the e-boiler, Vattenfall initially expects to be able to supply around 15% of the heat in the Amsterdam region with renewable wind and solar electricity. However, the number of hours that the e-boiler can run will increase in the coming years, given the growth in the number of wind and solar farms in the Netherlands.

In 2019, the company commissioned a 120 MW e-boiler in Berlin, which is so far the largest within the company.
