District Energy's Moment: Reflections on a Conversation Worth Having

District and campus energy has long been a proven solution for hospitals, universities, and industrial campuses. But 2020 changed the conversation. Speaking at the Distributed Energy Conference, Alex Marshall argues that rising demand charges and high-profile grid failures have created a compelling and urgent business case for CHP-based district energy systems that goes well beyond efficiency alone.

India's Energy Import Problem Has a Homegrown Answer: The Case for Biogas

India is one of the world's largest importers of oil and gas, and that dependency is a strategic vulnerability that ambition alone will not solve. Speaking at the World Biogas Association eFestival 2020 alongside the Indian Biogas Association and the Indian Institute of Chemical Technology, Clarke Energy's Alex Marshall sets out why biogas, underpinned by the Swachh Bharat Mission and the SATAT initiative, represents one of the most compelling and underdelivered energy opportunities in the world today.

Africa's Energy Transition Needs Local Infrastructure, Not Just Global Ambition

There is no shortage of ambition when it comes to Africa's energy future. But ambition without infrastructure delivers nothing. Reflecting on International Development Minister Andrew Murrison's visit to Clarke Energy's Knowsley facility in January 2020, Alex Marshall argues that resilient, distributed, locally maintained power generation not centralised grid ambition is the answer Africa's energy challenge actually demands.

Natural Gas and the Case for Domestic Energy in Uganda

Africa's energy challenge is not simply a question of resource scarcity. Uganda illustrates the tension clearly: significant hydrocarbon reserves in the Lake Albert basin, yet domestic consumers dependent on imported fuels, unreliable grid supply, and some of the highest electricity tariffs in East Africa. The case for redirecting a portion of Uganda's natural gas toward domestic use has rarely been stronger.

From the Lab to the Field: An Early Lesson in the Limits of Novel Technology

My route into energy and infrastructure was not a straight line. A postgraduate research project in environmental technology and a failed attempt to commercialise a promising water treatment innovation taught me something about the distance between a working prototype and a deployed system that I have returned to many times since. It is a lesson that still applies today, as the energy sector debates which emerging technologies will ultimately power AI infrastructure at scale.
