LONDON — When Jakob Bitner was 7, he left Russia for Germany with his parents and sister. Twenty-eight years later, he is set on solving a vexing green-energy problem that could help Germany end its dependence on imported energy from Russia, or anywhere.
The problem: how to make wind and solar energy available 24 hours a day, seven days a week, even if the sun is not shining or the wind not blowing.
The company that Mr. Bitner co-founded in Munich in 2016, VoltStorage, found some success selling storage battery packs for solar power to homeowners in Europe. Now the company is developing much larger batteries — each about the size of a shipping container — based on a chemical process that can store and discharge electricity over days, not just hours like today’s most popular battery technology.
These ambitions to overcome the unreliable nature of renewable energy fit perfectly with Europe’s targets to reduce dependence on fossil fuels. But Mr. Bitner’s company is facing a frustrating reality that threatens to undercut Europe’s plans and poses a wider challenge in the global fight against climate change: a lack of money to finish the job.
plenty of capital available globally for the multitrillion-dollar task of funding this transition to greener energy.
Europe’s Shift Away From Fossil Fuels
The European Union has begun a transition to greener forms of energy. But financial and geopolitical considerations could complicate the efforts.
The war in Ukraine has made Europe’s energy transition even more urgent. The European Union has said it will cut imported Russian natural gas by two-thirds this year and completely by the end of the decade. While some of that supply will be made up by imports from other countries, such as the United States and Qatar, expanding domestic renewable energy capacity is a critical pillar to this plan.
But attracting investors to projects trying to move beyond mature technologies like solar and wind power is tough. Venture capitalists, once cheerleaders of green energy, are more infatuated with cryptocurrencies and start-ups that deliver groceries and beer within minutes. Many investors are put off by capital-intensive investments. And governments have further muddied the water with inconsistent policies that undermine their bold pledges to reduce carbon emissions.
