Dürr Launches Qflex System for Multi-Fuel Automotive Ovens

Dürr released Qflex technology that decouples automotive paint ovens from specific heat sources. The system uses centralized heating modules compatible with natural gas, electricity or hydrogen without requiring structural oven changes. Dürr will offer two models: EcoInCure transverse ovens and EcoSmartCure longitudinal units. EcoSmartCure employs stop-and-go heating where bodies move through defined stationary phases.

Heating homes with hydrogen is bad for both your wallet and the planet

A review of studies looking at heating homes with hydrogen has found that high cost and poor energy efficiency means the gas isn't a viable

Hydrogen, often touted as a green alternative to heating buildings with natural gas or other fossils fuels, is unlikely to play a significant role in decarbonising homes, a review of international studies has found.

That is bad news for governments, including the UK, that are hoping to use hydrogen as a simple substitute for existing gas boilers. “I think hydrogen is ultimately the silver bullet,” Jacob Rees-Mogg, the UK’s newly-appointed energy minister told the House of Commons on 23 September. “We create it from renewable sources… we use it as an effective battery and it can then, with some adjustments, be piped through to people’s houses to heat them during the winter.”

The review by Jan Rosenow at the Regulatory Assistance Project, a non-governmental organisation, looked at 32 studies from the UK, European Union, California and São Paulo in Brazil. Overall, they show that hydrogen is “less economic, less efficient, more resource intensive and associated with larger environmental impacts”, writes Rosenow.

Heating with hydrogen could double consumer bills, report warns

Burning hydrogen instead of gas to heat homes and water could double consumer energy bills, at a time when consumers are already facing reco

Burning hydrogen instead of gas to heat homes and water could double consumer energy bills, at a time when consumers are already facing record-high gas prices, a new report has warned. 

As cheap fossil gas becomes scarce, some hope that hydrogen fuel will one day step in to fill the gap with a clean-burning alternative. Proponents of hydrogen heating, argue that existing gas boilers can be repurposed at low cost and reduce the financial burden of the transition to low-carbon heating.

Yet, with energy prices going sky-high, switching to hydrogen-based heating risks doubling consumer bills, warns a new report commissioned by Global Witness, an international NGO.

Even by 2050, households could spend an estimated average of 12.5 cents per kilowatt-hours (kWh) while average gas prices at the end of 2021 were but 6.7 cents per kWh, according to the report produced by the energy market consultancy Element Energy.

“The last thing that the tens of millions of people across Europe who will face energy poverty this winter need to hear is that their bills are going to go up again,” said Jonathan Noronha-Gant, senior gas campaigner at Global Witness, on Tuesday (6 September).

“MEPs and national governments must close the door on hydrogen heating, which is an unaffordable pipe dream,” he added.

Scientists have long sought to debunk claims about the merits of hydrogen heating.
