U.S. Policy Towards Sustainability & Energy Independence

Sewage Thermal Energy Use - A Practical Solution to Fossil Fuel Independence

Liquified Natural Gas (LNG) is in the news again with the Biden Administration's recent decision to pause the permitting of new natural gas production facilities in the United States. This is a calculated move because it reflects a long-term vision towards sustainability and energy independence. The U.S. policy is not just a reaction to current events, but a deliberate step towards addressing the broader challenges posed by our reliance on fossil fuels. However, this action has caused concern in European markets, especially in Germany where the US constitutes 80% of their LNG imports. It is important to note that current US exports are increasing, and new LNG terminals are coming online with new ones being built. This temporary pause is for those in the approval process. 

A significant portion of energy consumption in North America and Europe – about two-thirds – is for heating and cooling. In broad terms, if this energy could be recycled, then the need for primary fuel would decrease. Sewage Thermal Energy Use (STEU) is just such a technology. If two thirds of Germany’s need for LNG was reduced itself by two thirds. It would be like increasing their imports by 45%. Recapturing heat from sewage using a water-to-water heat pump with an easy to achieve COP of 3 or above is equivalent to reducing primary energy by 2/3.

Technologies like sewer thermal recapture is not just environmentally sound; it represents a practical solution to reduce our fossil fuel dependency. Utilizing all the heat we already produce (and not just flushing it down the drain) could enhance energy security and economic resilience. This approach aligns with a broader vision of energy independence, where we are not only more sustainable but also less susceptible to geopolitical tensions and supply disruptions.

The recent policy changes by the Biden administration, including the temporary pause on LNG exports to non-FTA countries, are part of this larger strategy. While primarily aimed at evaluating environmental impacts, these decisions are inherently tied to an emerging global energy narrative. They reflect a commitment to balancing immediate energy needs with long-term climate goals and geopolitical considerations. The U.S., as a major LNG exporter, plays a crucial role in supporting Europe, especially in reducing reliance on Russian gas. However, this role must be balanced with the need to transition towards more sustainable energy sources.

For Germany, reducing its reliance on LNG, whether sourced from Russia or the United States, is essential. One viable approach is to harness the potential of wastewater reservoirs. By tapping into this underutilized resource, Germany can move towards a more balanced and self-reliant energy mix.

Selling to European markets is obviously good for American producers, but diversification is good for producers too. The United States has an opportunity to expand its energy market and offerings. Through innovation, the U.S. can reduce costs and enhance the effectiveness of these technologies. Such advancements not only further domestic energy objectives but also position the U.S. as a leader in the growing sustainable energy sector.

As we have been saying for more than half a century - current energy challenges highlight the need for a strategic rethinking of our energy policies and practices. We need a holistic approach that promotes a balance of energy choices. Investing in sewer heat recapture is an important step towards a more sustainable, secure, and independent energy future. When we stop wasting heat, we will reduce the vulnerabilities associated with our carbon-fuels.
